Lenovo ThinkPad UltraNav Keyboard


As we’ve pointed out many times in the past, ThinkPads are well known for the quality of their keyboards. This has long been a strength of the ThinkPad brand, but when we say how good ThinkPad keyboards are we almost always implicitly mean “relative to the keyboards on other laptops”. That might not be the case for everyone though, because the ThinkPad Full-Size UltraNav USB Keyboard is currently available for sale and it is a testament to how attached people have become to these keyboards.

The UltraNav is just what you would expect: a ThinkPad keyboard modified to connect to you computer using a USB connection. It comes in two styles, Full-sized and Travel, depending on if you want a numberpad or not. Just like your T series it has dual cursor controls built in so you can control your mouse with the trackpoint or a trackpad under the space bar.

The keyboard itself, in our case the Full-sized model, is quite light and extremely flat. At about 15.5 inches wide and 8.5-inches deep it’s not exactly travel-sized, but it weighs less than a hardcover book and it keeps under 0.75-inches thick, so throwing it in a backpack or suitcase would not be impossible. . . . .



Despite being an external USB device, the keyboard’s layout stays extremely true to that found in a ThinkPad notebook. In addition to retaining the cursor controls (which do not require a second USB connection) the UltraNav has all the double-mapped Function commands of a notebook keyboard. These will have limited functionality on the desktop as a command like Fn + End (lower display brightness) won’t be able to control a normal monitor and the blue Access IBM button doesn’t work either. The good news is that the volume/mute keys work as did Fn + NumLk, which will get the Windows calculator to popup.

The real test of the UltraNav, of course, is typing. The layout is pretty much identical to that of a Thinkpad (plus a numberpad) so many people will instantly feel at home. Anything you like or dislike about the keyboard will still be present and features like the Fn key being in the bottom left corner or the Delete key being to the right of F12 (above Backspace) will obviously still be an annoyance if you don’t like them on the 8-row ThinkPad keyboards. The key action itself doesn’t feel quite as precise as that of the X300/X301, T500, T61, or some of the other keyboards that we’ve been using lately. Maybe it’s just the odd feeling of using a ThinkPad keyboard with my desktop, but the action feels a slight bit different. Without getting into minutia, the key action has a distinct “click” point which feels right but the keyboard seems a bit louder than it should be. Overall it’s a ThinkPad experience, but one without the feeling of a notebook behind it, and maybe that in and of itself is enough to lend the UltraNav a slightly ersatz experience. It feels good, just not perfect.



The cursor controls are just what we’ve come to expect: the red pointing-stick wedged between G, H, and B with the three buttons below it and then the trackpad with its two buttons. The trackpad was not sensitive enough to deal with my desktop’s 1920×1200 display, but the trackpoint was a bit better. Either way they would both benefit from using a higher sensitive setting than my normal mouse. Ultimately I ended up preferring the trackpoint, but that’s the same thing I use on ThinkPads so I doubt that my choice had anything to do with the UltraNav.



When we type on a notebook we accept that it won’t be quite as comfortable as it could be. When we are at home or in the office there is no reason to not be as comfortable as possible, which is immediately a mark against the UltraNav’s standard layout and very flat profile. It does have two settings with which users can incline the rear to improve the typing angle, but this will never be an ergonomic keyboard. It’s no worse than any other laptop-style keyboard by Logitech of a similar manufacturer, but if you are going to spend all day on something, this should be kept in mind.

The UltraNav sells fro $79.20 whether you get it with the numberpad or not. That’s no small price for a USB keyboard, but if you factor in that it includes a mouse and that it can be an excellent addition to any notebook (while retaining function commands) it might seem like a better deal. Plus either version would be good for travelling and you get that ThinkPad experience on any computer you want (laptop or otherwise). It’s a laptop-style keyboard is that is more expensive than some, and types better than most, but and despite its minor flaws and lackluster ergonomics, it’s going to be just want some people are looking for.

Casio offers best of both worlds with CA001 touchscreen phone


When Apple released the iPhone it created a market for mobile phones with touchscreens and other manufacturers have followed. Some people prefer the touchscreen interface, while others may still want access to a proper keypad. Casio’s latest phone aims to cater for everyone by combining both a touchscreen and a keypad.
. . . .
The Casio CA001 can look like both a typical clam shell phone, or a touchscreen input phone. It achieves this by using two separate screens – one is a touchscreen the other one isn’t. As you can see in the image above the CA001 looks like a normal phone sporting a keypad, but if you twist the screen round and lay it over the keypad you get something more akin to the iPhone as you can see below.



Casio have also included a 5 megapixel camera, Bluetooth, and a microSD slot. Buttons along the side of the phone suggest the company are going to push the music capabilities of the phone and it is also capable of wireless music playback with the right headphones.



Viewing the CA001 promotional website it looks like that are going to offer a range of dual-color case options including brown-black, yellow-silver, and white-silver combinations. There is also an area of the case that looks like grating, which actually turns out to be a very simple display showing the time and whether you have any text messages or e-mail. It is called the Illumi-Sign Sub Display and exists so you don’t have to fire up one of the main, energy-sapping screens to see if you have messages waiting.



The CA001 is set to be released this month in Japan, but there is no information on whether the phone will ever be released in the West.

Matthew’s Opinion
With touchscreen phones still being a fairly new addition to the range of models you can buy I’m sure a lot of consumers are still dubious about trying them. When you consider most will be locked into a 12 or 18 month contract with the phone they choose you can see why many would fall back on what they know.



Casio’s phone solves that problem. If you don’t like the touchscreen change the phone to the more well-known screen and keypad design. On the flip-side, if you are unsure about the touchscreen this is a phone that lets you try it safe in the knowledge it has an alternative setup.

I really like the Sub Display feature. It looks to be a very low power draw on the phone while active, but gives you the information you need before deciding to bring your phone fully out of sleep mode.

I hope we do see Casio bring this phone to Western markets, but as with many Japanese phones, it may stay exclusively in its home territory.

Why Techhnology Professionals Are So Important to Your Company


Of all the Technology Jobs in Massachusetts the CIO is one of the most important. Here is a little more information as to why they are essential to the success of any company:

CIO — Job Description: A database administrator (DBA) is responsible for installing, backing up, testing, securing and making changes to production databases within an IT environment. They work on ongoing development projects with developers and architects and, increasingly, with business-side workers. They also maintain operations on a day-to-day basis.
. . . .
Why You Need One: A company's data is its lifeblood and therefore it needs an experienced, skilled steward at the helm, says John Mahoney, a senior staffing consultant at Hollister, a staffing firm specializing in technology. "A good DBA—they really are tough to find," Mahoney says. "You're talking about the data integrity of the entire company."

Desired Skills: Companies and recruiters prize real-world experience—from several years to more than 10—over certifications (although those do help, especially for popular platforms like Oracle and, to a lesser extent, SQL Server 2000 and 2005). "The database experience we look for most of the time is Oracle," says Tom Hart, executive vice president of the operations and technology group at Veritude. "SQL Server is more of a 'nice-to-have.'"

Demand for other platforms, such as DB/2 and open-source offerings like MySQL, is much softer, say specialists. There is also not yet a great deal of demand for the newer SQL Server 2008.

Where to Look: Go to the likely sources to find DBA candidates, such as job boards for Technology Jobs in Massachusetts and user groups. The main problem, says Hart, is that there are "more DBA jobs than there are people to fill them."

What to Look For: Before the tech-bust, "clients just needed bodies," says Mahoney. Now, "they want DBAs to interact with different business units in the company. Especially in smaller shops, they want their DBAs to be able to go out and speak to end users and developers and figure out the crux of the problem."

Sean Gorman, who is a DBA with HiWired, a remote tech-support provider, agrees. "People who can sit down with business end users and collect requirements, that's huge," he says. "A lot of business users are big fish, and so you can't get pushed around. You're the expert and the one who's got to solve the problem, so you have to be able to push back if it is necessary."

Elimination Round: Mahoney says one of the first things he asks a candidate is about their knowledge and opinion of the client's operation. What comes out of their mouth—or doesn't—is telling, he says. "If they don't have an answer, if they're not prepared for me, why would they be prepared for the client?"

Salary Range: $65,000 to $130,000

Growing Your Own: Compounding the tight supply of outside candidates is the fact that it is difficult to cultivate DBAs within an organization, says Gorman. "I haven't seen a whole lot of that personally. The only two sources of people who would fit that role are systems people or developers," he says. "Typically, people in those two roles are in that because they want to be." Big enterprises, which may have multiple senior DBAs that can provide mentoring, are more likely to have success in grooming junior employees for DBA slots, Gorman suggests.

Significance of Laser Marking on UID Registration Products


It is mandatory for the UID registration products to have unique identification marks on them before they are submitted to the UID registry. The UID laser marking techniques bear huge significance for the marking procedures. As per the mandate of DoD the product identification must be directly as well as permanently marked on the surface of the part. As direct part marking and permanent identification are crucial to enhance traceability of the items, a reliable marking procedure is worth considering. Among all the identification marking technique for the UID registration products, UID laser marking is regarded as the most efficient and accurate one.

UID Markings for UID Registration Products . . . .

It is essential for the UID registration products to have the UID labels that comply with the UID policy. The marking is done with 2D data matrix codes that are encrypted to the surface of the products. The data of the UID labels are encoded with a specific language and format to be etched on to the surface. While scanning the data of the items, the codes are decoded with the help of Automatic Identification Technology. The coding and decoding technology of the laser marking system ensure highest level of security for the products.

Advantages of Laser Marking for UID Registration Products

The UID mark validation and the UID quality verification that comply with MIL-STD-130M have to undergo several techniques. To ensure that the marks on the UID registration products are legible for the life of the product, the DoD has implemented UID policy for the contractors. The immense popularity of the laser marking procedure is due to its benefits over the other methods of labeling.
The data required for the marking include enterprise identifier and unique number of the items. The higher resolution capacity of the UID laser marking enables embedding of more data in the UID mark.
Other marking techniques such as chemical etching, silk screening, mechanical engraving, pad printing, and some of the other low-quality methods are can not be considered as environment-friendly methods. On the other hand laser marking is surely an organic option to all these things that reduces carbon footprints.
Laser engraving and laser marking are exclusive techniques of identifying as well as decorating the UID registration products.

Other benefits of laser marking for UID registration products

The 2D data matrix symbols help the DoD in
boosting the inventory accuracy
sourcing the items on property accurately
enhancing access to lifespan of items and part history during design
decreasing workforce burden through increased productivity and efficiency
reducing inventory management cost

one of the most noteworthy aspects of laser marking is it can imprint the marks on any surface including auto parts, glass, plastics, pharmaceutical tablets, stainless steel, crystal, et all.

The UID verification of the UID registration products are changing faster and becoming more complex. Hence, the contractors and the suppliers need to understand the mandate of the DoD to comply with the UID program. UID laser marking can provide end to end solution for the requirements of UID registration.

Robots: America’s Answer to Dwindling Math Scores


The United States of America may lose its supremacy as a superpower if our children of today can’t grasp the technologies of tomorrow. The trend has already been set. High-level engineering jobs are currently being outsourced to other nations, not only because of cheaper costs, but inadequacies of filling them in the states. Let’s face it; there are not too many Americans who strive to have a doctrine in Electrical Engineering to do research and development. To other countries like Korea, many students see Math as the “universal language” and foresee a technically based doctorate level diploma as a necessity for excelling in their country. To many, this is the only road out of poverty. American children, stereotypically, do not have this fear to motivate them. Many children in this “superior” country just view mathematics as something needed to pass a proficiency test. Its value is discarded. The implementations are unseen. The desire of children to follow this type of career path is decreasing. Obviously, these future implications are disturbing and may some day be detrimental to the foundation of our country. However, I believe nurturing children’s enthusiasm in needing to use math may be the answer. Not surprisingly as stated in Robots for Kids, “Robots rank right up there with dinosaurs when it comes to grabbing the attention of elementary school students…” [1 p. 232]. Hence, I predict an interest, active participation, and proper guidance in robotics will increase nationally recorded math scores.

II. Staggering Math Scores

The facts don’t lie. According to the US Department of Education in 1999 [2], the United States ranked 12th among 4th graders, a staggering 28th among 8th graders, and just 19th among seniors in nationally recorded math scores. How can poverty stricken and problematic country like Israel be three rankings ahead of us with 8th graders? Clearly, money isn’t the answer. Nor do I believe Israelis have fewer fears about violence than our inner city children do to distract them. Although I’m a bit perplexed by the answer, I believe solution lies in a child’s own aspirations and inner desires. Many of our youth dream to be professional athletes or pop singers. That’s what they see. That’s what they know. That’s what they love. These young easily influenced children view these avenues not only as fun, but also as a means for financial freedom. With mathematics being the “universal language,” children in other countries may see this as the only way to break through levels of poverty and thrive in life. Let’s face it; math can be a difficult subject to grasp. Unless one either has the first name ‘Albert’ or discovers motivational reasons to put forth extra effort, the scores will suffer. The Third International Mathematics and Science Study (TIMSS) has found that “students who agreed that they like math and that math was useful for solving problems, scored higher than students who disagreed” [3]. To no surprise, many educators have already taken this as a given. The question that now arises is how to motivate the children? Or better yet, how does one follow a handed-down curriculum while taking advantage of today’s enticing technologies? As stated by Druin and Hendler, “I believe the desire for learning has to do with an animating idea or an engaging project. New technologies enable students of all ages to pursue richer, far more complex learning experiences. With robots, students can truly be scientists, engineers, designers, and builders” [1 pp. 161-62]. . . . .

III. Robots in the Media

Television may be lending a helping hand in the educational pursuit of sparking kid’s interest in robots. Maybe the eyes have been blessed to see Honda’s commercial of a 4 foot robot walking down the driveway to pickup a Sunday paper. This completely autonomous robot, which appears to be wearing a space suit, is currently on tour around the world. This “Advanced Step in Innovative MObility,” or better known as ASIMO, is the result of a robotics program that began in 1986. Being the most advanced humanoid robot in existence, this intriguing creation walks on two legs, has 26 degrees of freedom, can walk up steps, and is currently on a North American Educational Tour. Recently, this technological marvel visited the Bronx schools in an attempt to “encourage the interest in the study of robotics and science” [4]. Even a section on the website is dedicated to teacher’s resources for children. With ASIMO, Honda is truly giving our youth “The power of dreams” [4].

Sony is also doing its part to “Change the way you see world.” AIBO has become a pet of the future for many while the SDR-4X II is all the rave. AIBO is an autonomous dog that can learn, do tricks, and express feelings. This approximately $2000 piece of entertainment is completely programmable for upgrading and educational purposes. Be prepared for the pet to express 6 different types of feelings, act according to its environment and attention it’s receiving, seek out its toys, and without human help it will wake up and fall asleep on a charging station. Not only does the dog mature overtime, but also it won’t dirty the carpets as a puppy! The SDR-4X II, on the other hand, literally has become the rave among youngsters. This humanoid can be caught “raving” (a techno dance technique), throwing balls, doing tai chi, and even jogging. Even better, the video clips available on the Internet and television demonstrate five of them doing it in unison. And it gets better! This robot also has face recognition, a 20,000-word vocabulary for speech recognition and synthesis, color recognition, and still finds time to map out a room for optimum placement to show off. Now only if this thing didn’t need to be charged. Oh, did I mention work is already being done on that [4, 5]?

The stated robots do a wonderful job of creating attention for themselves and portraying to youngsters “cool” jobs to have when they grown up. However, I believe the television show Robot Wars is a driving force for inspiring them to begin building. I can vouch as living proof of that statement. Turn on TechTV and you will have the pleasure of watching robots battle to the death in an arena that has gusts of fire, pits to oblivion, and flippers that launch unfortunate robots through the air to their doom. Combine this with hundreds if not over a thousand screaming children in the stands and this show becomes a quick favorite. The program’s website even provides a daily quench for the thirst of building. Direct links are provided on how to start creating robots from home. GI Joes begin to look like baby toys in comparison to a 500 pound robot that shoots fire, spins blades, has crushing pinchers, and is moving strictly to survive and destroy someone else’s creation. Inside this 20- by 54-foot arena is the ultimate in robot combat and competition. Children love it [7, 8]!

IV. Creative Avenues

A common place many turn to when compelled to build a bot is David Cook’s book, Robot Building for Beginners. Following these instructions, not only will a line following robot be built, but math is unavoidably used and pursued. In order to understand speed, one must first understand Revolutions Per Minute, trade offs between speed and torque, battery levels, friction, robot mass and ways to manipulate these values with different voltages, gear ratios, and tire sizes. Trial and error is always an option and, might I add, a popular one amongst beginners. Remember, robotics is something that making a mistake is ‘OK’ and a tremendous amount of the learning results from these mistakes. However, this is where a teacher steps in and provides a ‘bag of tricks’ to the knowledge hungry children. I believe Miller and Stein say it best when they detail reactions from a second grade class:

“…several students will stare with awe and admiration at the one or two students who know their multiplication tables and can predict how many times a motor needs to turn to make the wheel on their robot turn once… All of a sudden radii, circles, circumferences, and so on have utility—as one of our students suddenly loudly exclaimed, “So that’s what pi is for!”” [1 pp. 231-32].

Wow, all that to just determine speed. Lets not forget that the person reading the book is going to learn about materials science (i.e. textile strength), basic electronics (voltage = current * resistance), mechanics (loads and stress), diodes, resisters, capacitors, LEDs, and all the tools and procedures to use them effectively. At first glance, this may seem like a lot to learn for a child. Remember this: it’s not the teacher’s lessons being forced on the kids, it’s their own! What child becomes enthused with a question stating, “If Jack is half as old as Jill, and Jill is one third as old as Jan? Then how old is Jack on Jan’s 60 birthday?” Building robots is a teacher’s dream--true problem solving with the added benefit of enthusiasm [9].

With DC robots, the sky is the limit on how technical the project will become. However, sometimes quicker and less complex solutions may be more appropriate. BEAM technology uses solar energy to power very simplistic, yet captivating, robots. This acronym for Biology Electronics Aesthetics Mechanics represents an area of robotics using no computational power, inspirations from Mother Nature, a focus on designs that appeal to the eye, while making it all work with the small amount of power given from a solar panel. There are rarely circuit boards used, no programming is involved, and just a few inexpensive are parts needed. My first BEAM robot involved a paper clip, a pager motor, a solar panel, a capacitor, and a little solder. In about 20 minutes, the 5 parts came to life! The beauty of these robots is the simplicity to build, the parts are cheap to buy or easily found in techno junk around the house, and only a soldering iron is necessary to build them. While these robots generally take the form of a bug or some other small creature, they have a large appeal to children. Projects are very quick. This fact alone adheres to those with a short attention span who want immediate feedback on their progresses. In addition, many of the basic principals of science and biology are incorporated in the design and can be discussed with respect to solar energy. Visits to the zoo will become more educational as children will seek out animals to mimic their moments and appearance. “Construction material and project ideas that appeal to a broad range of interests allow multiple entry points into science, mathematics, engineering, design, art and music for all types of learners. These materials not only make new knowledge domains accessible, but also provide new ways for children to relate to domains of knowledge to which they have already been exposed” [1 p. 22]. In addition, an obvious challenge of this solar technology is to minimize the current used and find ways of storing (capacitors) what little energy that is available. Hence, young robotists will learn the importance of reading and comprehending part data sheets in order to choose the appropriate parts wisely. Naturally, some of the most basic problem solving techniques are utilized at its finest [10].

When the pupil is young or the soldering skills have not quite matured, Lego Mindstorms is always an exceptional choice. Actually, anyone of any age will find this technical and robotic line of Legos a wise investment. Not only are the parts reusable and nonexclusive to a particular project, but also they can be programmed in various languages on a computer from Visual Basic to Lego’s own object oriented programming language. No cables are needed either. All of this can be done via an infrared transmitter! It’s difficult to fathom how Legos have walked hand-in-hand with technology. For example, let’s take a closer look at the kit “Robotics Invention System 2.0.” This set includes a battery operated RCX Microcomputer used to store programs and connect all the peripherals, 718 pieces which include 2 motors, 2 touch sensors, and 1 light sensor, a USB infrared tower, and a simple yet powerful picture based programming language on CD. Of course, all the Legos from any of the prior kits can be used in conjunction with this educational tool. In addition, at the Mindstorms website, there is a free online program in which to create projects choosing any Lego in existence. This 3D virtual environment is ideal for posting creations on the web or experimenting with Legos that have yet to be purchased [11, 12, 13].

As a result of the software included, children can have their first robot built in less than an hour after purchase. There are a slew of practice lessons, training sessions, and missions included on the CD. Each of these training sessions teaches a specific capability of the Robotics System while describing various ways to test, troubleshoot, and tweak the constructions. Eventually, the lessons will escalate into such capabilities as: using sensors to interact with the environment, programming with icons that represent blocks of code, and create environmental responses for the robot to do anything its creator desires. By the time the CD is completed, nearly all the fundamental techniques necessary to complete projects will have been covered [11, 14].

Already, there are over a dozen books written about Lego Mindstorms with detailed how-to’s of creating everything from a scanner, musical instrument, and a picture creator, to a spy bot, fingernail polisher, and M&M color sorter. I even own books that describe the creations of an ATM machine, card dealer, elephants that squirt water, and even a robot that does the work of cleaning the Lego’s from the floor [15]. By completing these projects, according to Cole and O’Conner, “(Educational) benefits include helping children to improve their concentration skills, work with instructions, problem solve, and develop patience” [16]. This line of Legos created by MIT professors is currently being used with thousands of educators across the world. Since most children only view the robot as a “toy”, they tend to stay highly focused and engaged throughout the lessons. Thus allowing more productive group settings, more creative and in depth solutions to given scenarios, and development of interpersonal skills and team-building skills. All of this is accomplished without the use of a pencil [17, 18]!

V. Case Study

If something can’t be measured, then I believe it cannot be proven or improved. My hypothesis is that with an interest, active participation, and proper guidance in robotics, the TIMMS scores on average will increase at least 10 points over a year’s time. Since the tests are taken at 4th, 8th, and 12th grade years respectively, this undertaking would need to involve an entire school system and then relate the scores to the year’s prior. Remember, the content of an experience, and not so much the tools, are what is vital to learning. Hence, the roles, guidance, and trainings of the teachers and designated robot/BEAM/Lego Mindstorms “experts” cannot be stressed enough. It is naive to consider placing a computer in front of a person and expecting one to be capable of building a network, creating a webpage, or becoming fluent in a programming language. The same goes for robotics. When launching this curriculum upgrade in the beginning of a fall school year, it is essential to educate the teachers during the prior summer. Obviously, this time will be spent to understand the equipment, discuss and personalize previously created and borrowed lesson plans, and provide an entire summer of uninhibited experimentation. However, this is also a period to overcome any fears or dislikes of technology and change. “For example, some people uncomfortable with new ways can replicate the old ways by using technology. It is a safe way to sneak up on change… Some teachers, who have little experience with new technologies in their classroom, have been known to force-fit new technologies to well-worn curricula” [1 p. 159]. For this case study to be effective, educators must embrace breaking through the mold of “old school” comfortable habits and adhere to the potentials of what technology can foster. This is, of course, the pursuit of “richer, far more complex learning experiences [1 p. 161].

The procedure itself is laid out in a similar pattern amongst the different grade zones. Months prior to the start of the school year, a letter detailing the curriculum changes should be sent out to all the parents. This letter should brief the intentions and communicate resources that a parent could turn to for pre-exposure to themselves and their children with the upcoming technologies. Parental support and involvement are essential to exceeding expectations in this new process.

A. Elementary School

Beginning with the elementary level, grades 1-5, the year should begin with a speaker. Here, Lego Mindstorms will be introduced and accompanied with a display case full of inventions. Demonstrations will be shown to all. This will incite interest and curiosity amongst the listeners. Also, leaving these creations in a strategic trophy-case-like display will perpetuate the excitement and foster a desire for involvement. Lego Mindstorms will be added to the curriculum. This time invested can be substituted for some of the weekly sciences and designated math time slots. When executed properly, the lesson plans of different mathematical principals can be shared as helpful hints to the students. Also, in replacement of the annual science fair, a “Lego Fair” could be established. This will provide for more parental involvement regarding the Mindstorms. How many projects are really done 100% by the student anyway? Also, a sense of pride and achievement will be attained in the ownership of a creation on display for everyone to see. In addition, having the student stand by the project during showing to answer questions and provide detailed descriptions and demonstrations will solidify the understanding, theories, and principles used in the creation process.

Just as in high school, I believe tenure and seniority should have its perks. Assuming the continuation of this curriculum advancement, 4th and 5th graders would eventually have 3 and 4 years of Mindstorms experience under their belts. Thus, allowing for more advanced projects and deeper problem solving capabilities. To add fuel to this fire, a monthly competition could be established solely for the “upper class people.” This could involve creating a solution to build a robot that follows a line and picks up Legos, a race around a track following a line, or even a robot that can navigate through a simple maze. Whatever the challenge; a secret agenda should be accomplished. Carefully choose a project that is best solved using principles that coincide with the forecasted science or mathematical lesson plans that month. I believe this would serve as an honor to be old enough to participate in these activities. Student involvement would inevitably increase as a result. Also, what’s better than having a child seeking out mathematical tricks from the teacher, i.e. how to use fractions for simplification of programming timings, in an attempt to gain a competitive advantage over a fellow classmate? Stated in business terms, competition fosters innovation. Then last of all, administer the TIMMS tests and compare the scores to a prior non-Lego integrated year. . . .

B. Middle and Junior High School

In a similar fashion, grades 6th through 8th will experience robotics with a heightened level of technical skills necessary to complete the projects. The main differences are the integration of electrical components, basic electrical principles, soldering techniques, and solar technology used in the foundation of BEAM technology. A guest will also be brought in at the start of the school year for the technical overview and exhibitions of a display-case amount of BEAM robots. However, this speaker will also be an electrical engineer. This expert will relay the pertinence of the BEAM skills to be learned as they are utilized in the real world. Also, the professional should state the educational path best taken in math and science to prepare for a college major in this field. As with the elementary children, the creations will be left on display and questions will be welcomed both during the presentation and on a one-on-one basis.

Since students will more than likely be changing classes for the different subjects, the science labs should be equipped with the necessary tools for the solar robots. This robotics class will need to be slotted in a certain portion of the week in replacement of the sciences. In addition, a yearly BEAM robot fair should also be created. Robots that interact, seek out light, and intertwine independent ideas (as apposed to just following directions out of a book) should be suggested. A new twist will be added to this fair though. Students will be required to provide a write-up that details schematics, electrical calculations, and descriptions of the robot. This should even include how light transforms to energy for the motor. This insures that the student is actually understanding the creation and learning the principles—not just excelling in the field of directions following. If the Beam Robot Fair is the yearly event for all grades, the monthly projects for the privileged 8th graders could be a robot race. I would like to better name these functions “The Solar Roller Races.” Here, students will create solar powered drag cars to race their fellow classmates. These simple creations will be entered into a bracketing system in which the monthly winners will have their names engraved on an annual plaque. Winners could be encouraged to retire that car and work on a new one for the next month. This will encourage continued devotion to these races from everyone. And as the last step in this process would be, TIMMS test should be administered to the students and compared to prior non-robot years.

C. High School

With no surprise, the most involved, demanding, and in depth robotic projects will be asked of those in high school. The sky is the limit on the complexity of any project here. Also, in hopes of keeping the robotics program alive for many years, those who began with the Lego Mindstorms will be able to utilize their skills since first grade on the projects. Robot bases can easily be made of Legos and light can also be used as a power source. Students will eventually learn there are advantages and disadvantages to every decision they make.

The school year for grades 9-12 will follow in line with K-8 and begin with a visit from a speaker. This speaker will be an Electrical Engineer fluent in the field of robotics. Again an overview will be given, creations will be demonstrated, a Q/A session will take place, career paths will be detailed, and specific class routes will be suggested. Although the speaker descriptions appear to just be reiterations of other grade levels, the importance cannot be stressed enough. Many teenagers begin career paths based upon what they enjoy. Hopefully, those who become passionate about robotics understand the importance of accelerated classes for technical majors in college. This fact cannot be forgotten. The classes specific to robotics will be offered to each grade level with increasingly more in depth coverage for the higher grades.

Also, instead of a yearly robot fair, I desire the yearly event to be participation in FIRST. “For Inspiration in Science and Technology” is a 6 weeklong competition modeled after an MIT 2.70 mechanical engineering class [1 p. 248-49]. As described on the FIRST website:

“The FIRST Robotics Competition is a national engineering contest which immerses high school students in the exciting world of engineering. Teaming up with engineers from businesses and universities, students get a hands-on inside look at the engineering profession. In six intense weeks, students and engineers work together to brainstorm, design, construct and test their “champion robot.” With only six weeks, all jobs are critical path. The teams then compete in a spirited, no-holds-barred tournament complete with referees, cheerleaders and time clocks.

The partnerships developed between schools, businesses, and universities provide an exchange of resources and talent, highlighting mutual needs, building cooperation, and exposing students to new career choices. The result is a fun, exciting and stimulating environment in which all participants discover the important connection between classroom lessons and real world applications.

Each year, the competition is different, so returning teams always have a new challenge to look forward to. However, the details are kept secret until the unveiling at the Kick-Off workshop. This provides a high level of excitement as everyone sees the new challenge for the first time and ideas immediately being forming in people’s minds” [19, 1 pp. 248-49].



Upper class people will also have their privileges in high school. The monthly event open to 10th and 11th graders could be robot sumo. Here, students will create completely autonomous robots and mimic the rules of one of Japan’s most popular sports—sumo. Instead, the idea is for the size and weight class restricted robots to push each other out of a circular ring. Robot sumo has already made its way into many robot clubs, high schools, and universities. The popularity of this event can be credited to its low part costs and simplicity of rules. In 2001 alone, more than 4,000 robots competed in a 4-month season in Japan and those numbers are growing at an exponential rate. Innovation is what keeps this “game” growing in numbers and proves invaluable for student participation and educational advancement [20].

Naturally, in order to prove my hypothesis, the high school students would also need to be administered an internationally recognized TIMMS exam. These scores would then need to be compared to non-robotic years.

VI. Conclusions

Although the robotic case study has not been implemented to test my hypothesis, I will make predictions on the findings. As forethought, I also believe the conclusions to be correct to a high amount of accuracy. There are many ingredients to this success and I will attempt to touch on most of what I consider obvious outcomes. However, as a person of science, I admit that these ideas are not factual and even incomplete without the study actually taking place.

Public displays of projects and competitions have fostered extraordinary outcomes. So does the cooperative participation with all students. In time, I believe this will portray robotics as a “cool” thing to do in school. This being the case, some of the educational barriers will be hurdled in the process. Especially during the competitions, students will be working with the adults and not for them. Realizations that it is not the gender, race, creed, sex, or social status that matters in reference to partnering in robotics, but what they know and can contribute to the cause is a vital lesson. The differences in people will be grayed out while their possibly unknown qualities will shine. Robotics gives a chance for people who generally wouldn’t have associated with each other to seek each other out for their robotic potential [1 pp. 287-88].

Specifically looking at gender differences, it is important to note the participation of females in robotics. A finding from Robocamp states, “It appears that girls in particular may need encouragement and a formal structure in order to experiment and be creative… They would do more advanced exercises only when specifically asked” [1 p. 321]. Another finding exhumed from the book Robots for Kids details finding at an elementary school in Reston, Virginia. Believing the importance of ideas to be best left in the author’s words,

“We (KISS Institute for Practical Robotics) distributed flyers to the fifth and sixth graders (ages 10-11), and the next day 30 registrations appeared: 29 boys and 1 girl.

This overwhelming imbalance highlighted an obvious need to reach out to girls, and this inspired immediate action on our part. We received permission to present short robot demos for second graders. During these demos, students were invited to push buttons, flip levers, and otherwise interact with a couple of real robots. We then distributed flyers to the second graders for an after-school robotics class. This time we had enough response to form two classes, and about 40 percent of the registrants were girls.

Four years later when this group became sixth graders, we again offered a fifth/sixth-grade class. This time half the students who signed up were female. None of this resembles an actual scientific study (why we are developing); however, there was a fairly strong indication that when students had a fun experience with robots at an early age, they were much more likely to pursue that topic at a later point in their life. Presumably, the same effect would occur later in life, in that students would be more likely to choose college courses and/or career paths further down the line after having been exposed to fun experiences with robotics in middle and high school” [1 pp. 232-33].

Along with the proposed findings that more students will choose a technical career later in life, I believe that local robotics clubs will also begin forming in the community. This will lead to in depth community involvement of older more experienced people volunteering for robotics help in the local schools. Hence, this cycle will lead to better teachings and of course better projects. Also, I believe this will help perpetuate a more enjoyable school experience for children. This can be proven just by a jump in attendance. Another way to validate the statement is to look at the children’s Christmas/birthday lists. I believe they will include more robotic related materials than before.

All of these reasons encapsulate why math scores will improve. More specifically, I believe scores will improve by at least 10 points on the TIMMS scores as compared to non-robotic years. I say this because,

“In regular classes many teachers try to use grades to motivate students, and sometimes they miss the mark. It is best for students to push themselves to excel, so teachers give exams to test student achievement and attach a grade to motivate students to do their best. But one of the real problems of…education is that grading standards vary widely and continually slip downward. At the same time, students would seem to be foolishly wasting their time if they did anything more than the minimum required to get an ‘A’ in a class” [1 pp. 289].

Also, I foresee a higher enrollment in advanced math and science classes. This is, of course, a result of more students having their eyes opened to technical careers and taking proactive educational steps to achieve these dreams. If more students enroll in advanced math classes, then more students will score better on nationwide math based exams. In addition, lets not forget that students have been unknowingly working on problem solving skills and math based robotic inspired formulas for the duration of the year. The best part is that these processes were probably utilized in a majority of the student’s free time as projects were being created and completed. If portions of students are inspired to focus on robotics every spare hour they are free, increased math use is unavoidable. Hence, with this practice, so is improvement upon these skills. A 12-year long study of the continued robotic intervention of the 1st graders to their 12th grade testing would be interesting. The implications of perpetuated involvement in the robotics field would be fascinating.

People under the legal age of 18, or dare I categorize them as children, possess all the tenacity, creativity, and capacity to learn, as do adults. Channeling these incredible energies into something as positive and productive as robotics will have effects that ripple on beyond our comprehension. As best stated by a high school participant in FIRST, Daniel Lehrbaum shares his insight on people.

“…I think if students are put in a position where their opinions are valued and their designs are valued and people listen to them, suddenly they can rise to that new level. I think the one thing is that people fill the shoes that you put them in. If the engineers and advisors (that assist the team with FIRST) put them in really big shoes, they are going to fill them. They will do the things they need to do to get the job done. Especially if they are, you know, dedicated to the cause. People can do incredible things” [1 p. 271].

Honda’s Continuing Progress With the Asimo Robot and the Honda Odyssey


Honda (producer of high quality auto parts like Acura CL EGR valve) has recently achieved another breakthrough in the field of robotics when it has successfully made two humanoid robots to work in pairs.

The demonstration was held in Tokyo where the two child-size ASIMOs were made to serve tea and do other tasks in coordination with each other. According to Honda, the new robot buddy system enables the humanoids to share information on each other’s location as well as keep track of each other’s activities. . . . .

To demonstrate the new capabilities of the ASIMOs they were made to make their way around the room while pushing a refreshment cart then picking up and setting down drink trays.

According to the automaker the upgrades that they have put on the ASIMO robots allow them to recognize drink choices and to carry a tray with the particular ordered drink. The most amazing about the ASIMO is the part where they can analyze and at the same time predict the movement of real humans enabling them to avoid getting in the way.

Dodge Minivan to Bow Down to Honda Odyssey
Aside from the ASIMO, Honda’s Odyssey is also making waves and it may grab the minivan crown from Chrysler.

It can be noted that it was Chrysler that single-handedly developed the minivan market segment with its Dodge Caravan and the Chrysler Town & Country. Since the introduction of the Caravan in the US in 1983 it has become the top-selling minivan.

But it seems that Chrysler will not be holding the minivan crown for long especially with Honda selling over 158,139 Odyssey minivans compared to the 154,824 Dodge Caravans sold in the same period that is according to data gathered by AutoData.

Chrysler’s sales suffered for 2007 because of changeover to the new version that is according to Chrysler spokeswoman Beverly Thacker. Aside from that more buyers are shifting to crossover SUVs thereby reducing further the minivan market share. The Caravan sales are now down by 21 percent as compared to the number it sold by the end of November in 2006.

With regards to total minivan sales including Chrysler Town & Country and Dodge Caravan, Chrysler LLC remains to be the market leader with 279,000 units of minivans sold. But despite this fact industry analysts thinks that Chrysler need to do better than that, if it wants to keep the title as US best-selling minivan especially with Honda working hard to improve the sales of its minivans and so far it’s doing a pretty good job.

Honda Unveils Latest Asimo Robot at La’s Consumer Electronics Show

>In California: Honda, the world’s creator of the first ever ASIMO robot has one again made another breakthrough with their humanoid creation. Honda’s latest ASIMO was presented at the Consumer Electronics Show (CES) in Las Vegas, Nevada.

The new ASIMO has been upgraded and was given a streamlined of new design. Honda’s ASIMO is now more agile and is capable of quick movements – such as running nearly 4mph. Aside from the ability to run, the humanoid robot was also provided with artificial intelligence capabilities to further enhance human interaction. . . . .

Jeffrey Smith, American Honda Assistant Vice President was the one tasked of presenting the ASIMO during its North American Debut at the CES. And here is what he has to say about the ASIMO:

“For the first time in North America, we’re demonstrating this newest iteration of Honda’s remarkable humanoid robotics technology. ASIMO now has a revolutionary ability to run and maneuver at unprecedented speeds… Honda continues to further the development of humanoid robotics technology, believing that one day ASIMO will be a helper to people in need.”

“The new ASIMO can much better interact with and carry out commands given by people and can more effectively perform numerous new tasks including moving carts and carrying objects. The primary advancements of the newest ASIMO include:
Enhanced human Interaction- By providing ASIMO with the ability to recognize the surrounding environment through its visual sensors, floor surface sensor, ultrasonic sensor, and by an IC Tele-interaction Communication Card1, ASIMO can more autonomously interact with people. Through the coordinated use of its eye cameras in the head and the force (kinesthetic) sensors on its wrists, ASIMO can give and receive an object such as a tray. And by using these force sensors, ASIMO can hold the hand of the person and move in sync with them.
Carrying objects using a cart- ASIMO is now capable of handling a cart freely while maintaining an appropriate distance from the cart by adjusting the force of its right and left arms to push a cart using the force sensors on its wrists. Even when the movement of the cart is disturbed, ASIMO can continue maneuvering by taking flexible actions such as slowing down or changing directions.
Running- Through proactive control of ASIMO’s posture while both feet are off the ground, ASIMO can run at nearly 4 mph. In addition, running in a circular pattern at a high speed was achieved by tilting the center of gravity of ASIMO’s body inside of the circle to maintain balance with the amount of centrifugal force experienced.

The main objective of Honda in pursuing the development of the ASIMO robot is to one day create a robot that would have ability to assist those whose mobility are restricted and to replace those who are working in environments that are harmful to humans.

Facts on Honda
Honda is one of the leading producers in the world of various types of mobility products such as automobiles, motorcycles and ATVs, power products; top-of-the-line auto parts products like Civic tie rod end, marine engines, personal watercraft, and light jet. Honda has started its North American operations in the year 1959 with the American Honda Motor Co., Inc. as its first overseas subsidiary.

At present Honda is employing 35,000 associates and operates 13 major manufacturing plants. A great number of Honda products are designed and developed at Honda’s US R&D centers in Ohio, LA and North Carolina. Honda spends $16 billion annually for parts and materials for its North American operations.

More and more Robots on the Way

Many years ago nobody would have believed that robots would become such a big part of the world. But as technology advances this is becoming more and more realistic as the years go by. At this time, robots are used within a variety of industries. There are both pros and cons of robots taking over in some regards, but despite the potential drawbacks there is no slow down in sight. The number one benefit of using robots is that they are more accurate than humans. Once a robot is set to perform a specific task it can do so the same way, time after time. Obviously, this is something that humans cannot do no matter how skilled they are. To go along with accuracy, robots can also save particular businesses a lot of time. Thanks to superior strength and technology a robot can perform many tasks much quicker than humans. This alone is reason enough to consider robots valuable. After all, the more time that is saved the more products that can be produced. Finally, robots can help save money. Although robots may cost a lot upfront they don’t ask to be paid a salary or for benefits. With the use of robots many companies have been able to cut back on production costs. Of course, robots are harmful in the way that they take jobs away from humans who used to complete the same tasks. This is something to keep an eye on as robots become more sophisticated and widely used. There is no denying that robots offer many benefits within many industries. More and more robots are on the way, and there is no slowing their progress down at this point.

Thermal Profiler for Wave Soldering Process

Among the different process involved in the wave soldering process thermal profiling is one of the most important processes which can affect the wave soldering process to a great extent. Thermal profiling is one of the most important processes which should be performed very carefully so as to make the production of the printed circuit board good in quality. Thermal profiling is done during the travel of the printed circuit board through the whole process. . . . .

Thermal profiling is the process of measuring the time against the temperature during the whole travel of the product through out the process from the beginning to the end. The collection of the data like the peak temperature, time above the liquids, immersing of the product into the wave and more also comes under the process of thermal profiling during the wave soldering process. These whole processes comprises of the thermal profiling process for the wave soldering. The data collected during the thermal profiling process helps in making the process of wave soldering even more efficient and to bring a valuable improvement in the quality and the consistency in the quality of the product. So we can say that the process of thermal profiling is an important part of the process of wave soldering and it contributes in a successful completion of the wave solder process.

The devices used for the thermal profiling is known as the “Thermal Profiler” or some people even call them as “Data Loggers” for the proves of the wave soldering. Actually the thermal profilers are basically the temperature recorders which are used for keeping the record of the temperatures during the whole process and they have the capability for traveling through the complete process of wave soldering along with the product so as to get the actual reading for the temperature that the product observes.

There are various thermal profilers or can say temperature recorders available in the market but there are some specific companies which manufactures the thermal profilers especially for the wave soldering process. These thermal profilers are used in the reflow profiling process of the wave soldering. These profilers also help in optimizing the wave soldering process. They provide pretty accurate data for the whole process which makes the optimization for the process even more affective.

General thermal profilers are equipped with the thermocouple based sensor which is attached to the surface of the PCB and then the PCB is made to travel through the thermal profiler which helps in monitoring the complete data for the wave solder process. The most common thermal profiler is the one which downloads the information while it is passing through the whole process.

Now these thermal profilers have become a must for the people involved in the business of the PCB manufacturing. It helps in optimizing the process of the wave soldering to make it even more efficient.

The Secret To Door Panels And Door Speakers

For some, the prospect of changing out speakers is a daunting one, since you have to remove the door panels to access the speakers tucked away within its walls. They are not a tricky as they seem, if you know the right techniques.The first thing to do is to locate any screws holding the panel in place. These are generally found in or under the armrest piece, in the door opener latch, or near the bottom of the door panel. Remove as many as you can find to start.With the screws removed, you will need to carefully.... pry the door panel off the door. Start in the bottom corner nearest the speaker. Gently pull the panel until it pops loose. There are usually several clips holding it in place. Work around the bottom of the door panel popping the clips out. Be careful to not break them, because you will need them to reinstall it. Continue around the outside of the panel until you have removed as many of the clips as you can. If you have power windows, doors, etc, remove the control panel from the door panel. It is usually clipped in place, and can be carefully pried out. Look for small notches that may give away the position of the clips. If you have mechanical windows, you will need to push the door panel into the door at the window crank, and look for the snap ring clip holding it in place. With a thin flathead screwdriver, pop the clip loose, taking special note of where it goes, as you will need it to secure the piece back in place. Once this is removed, you should have enough clearance to reach the speaker. If not, you can attempt to completely remove the door panel by sliding it upwards and out of the window compartment. You may be caught up by the door opener latch. These can be a little tricky, as some will slide in place horizontally, screw in, or pop out. Look for screws, and if you don't find any, try sliding it horizontally towards the inside. If that doesn't work, see if it pops straight out. It will be connected to the bars that pull the door latch, so they will have to be positioned correctly for the door panel to be removed. If there is a triangular piece of trim in the top corner of the door panel, you will need to remove it also. It also clips in place and can be removed. This should allow the door panel to slide out, assuming you have disconnected the control panels electrical wires.You should now be in full view of the door speaker. it can be removed by removing the four screws holding it in place. You may also find that the connectors on these speakers won't work for your aftermarket ones, so you will have to clip the wires and attach the end connectors provided with your speakers. Pay attention to positive and negative here. If you are unsure of what is what, there are a few ways to check. Look at the terminals on the factory speaker. It may have a "+" and "-" sign designating positive and negative. If it doesn't tell you, you can log on to installdr.com and look up the color codes for the speaker, or try the battery test. Take a good charged battery and place one of the factory speaker wires (attached to the speaker) on the positive, and one on the negative of the battery. If the speaker pushes out, the polarity is correct as you have it, and attach the wires accordingly. If it pushes in, the polarity is reversed, so reverse the battery and try again. If it pushes out, wire the speakers following that polarity.Install the speaker in the door by replacing the 4 screws and securing it in place, and reinstalling the door panel. be sure to slide it back down in place, and line up the clips exactly before applying pressure to reattach them. You don't want to break any of those. Finish screwing the door in place, then attach the window control panel/window crank, and congratulations, your done! Read More...

How Do I Start A Hot Engine In Summer?

It is usually a cold engine, which is exposed to extreme weather that most often is difficult to start. However, hot engines sometimes have problems too. Hot engines can be tough to start, and many people do not know how to deal with this situation when it occurs. With the intention of overcoming this dilemma, it is important to know exactly why it happens.

The most common reason why a hot engine will not start is because... the problem is related to fuel. When your car engine is too hot, fuel cannot circulate well, due to the way vapour obstructs it workings and therefore the engine just will not start, as it should. You can find out more information on this subject online at autopages.com.au who suggest to keep your engine running at the correct temperature and to protect its alloys and metals, you need to use a properly designed coolant.

A car engine will keep gaining temperature until it has been turned off. During this time is when the highest concentration of vapour is circulating around and chances are, that it shall obstruct the engine to a greater extent. Obviously, when and if you are driving in hot weather and have just turned off the car engine you may experience start problems. The solution is simple; you must wait for a few minutes until trying to start it again. The most sensible solution of course, is to use a high quality engine coolant.

Fuel injected engines do not experience this problem as much as other engines, because the fuel remains inside the injectors under high pressure. Owing to this, fuel injected engines do not become so easily subjected to vapours as other engines. Therefore, the vehicle does not have the same issues when it comes to starting a hot engine. It may be time to change over your old vehicle to a newer model with fuel injection, and when this becomes an important issue, you can go online to OzFreeOnline.com and begin a quick search by entering and submitting all the data you have researched for your new car. Let OzFreeOnline.com do all the work for you.

Another reason why you may have an engine, which is hard to start while hot, is that it may be due to seasonal weather as refiners change from one fuel blend to another. Petrol refiners often change a higher volatility fuel to a lower one when summer approaches. This is simply because hot weather causes fuel to evaporate more quickly. If refiners change back to a higher volatility fuel, while vehicles are still exposed to days of extreme temperatures, this may cause swift evaporation of the fuel which, in turn would create too much vapour within the engine.

Refresh Engine with Radiators

Automotive radiators are the important components of a vehicle's cooling system. A vehicle's cooling system is intended to protect the engine from the destructive forces of too much heat. Radiators take charge of removing excess heat from the engine even under the most extreme conditions. Cooling the motor helps it last longer, taking the vehicle to the distance. If the system isn't in good repair, simple tasks such as sitting idle in rush-hour traffic can cause a vehicle to overheat even when temperatures drop below the freezing mark.

Radiators extend engine life, and keep.... the vehicle's engine at a safe and efficient operating temperature. Without passing the hot coolant through the cool metal grates or cooling cores of the radiator, the incredible heat under the hood of the car or truck would cause the vehicle to very rapidly overheat, potentially leaving the driver stranded. Intense heat could also destroy other parts of the engine that can be very costly to replace. The radiator is a heat exchanger designed to transfer thermal energy from one medium to another for the purpose of cooling and heating. After which, it transfers the heat from the fluid inside to the air outside, thus cooling the engine. This heat-dissipating device is connected to channels running through the engine and cylinder head, through which pumps a liquid.

On some cars, the radiator fan is electrically driven and comes on automatically even after the engine has been turned off. Disconnect the ground wire from the battery before starting to work to keep away from injury. Since the engine works harder than most of auto parts, it has a tendency to overheat; therefore, it needs a cooling system that would keep it operating at the right temperature. Radiators protect the engine from the destructive forces of too much heat.

When you find a leak because of a rock, a hose, or sometimes because of an accident, replace the radiator to allow motor to continue working and be cooled as it should. Overtime, dirt, dust and rust can build up and clog the essential components of the car's radiator. Therefore, routine maintenance can slow this process and makes the life of the radiator temporarily longer. Timely radiator replacement is also important when the current car radiator wears out.

Be aware of the serious responsibility that comes with driving and car maintenance. Reduce much of the risks with cars by simply being safety conscious and always check radiators to guarantee protection and long time performance of automobiles.

Search Engine Optimization: Gearing Up For 2008 and Beyond

The SEO paradigm shift has already started kicking in. As search engine algorithms evolve, more weight is placed on trust-based factors and topical-relevance forcing marketers to sharpen up or lose their edge. Keyword density, perfect anchor text alignment and sheer volume of link equity will not cut it any more.

Mainstream Media Engagement

If marketers are working with brands... that have an established off or online presence they already have a key advantage. Mainstream media and B2B publications with established trust will likely link to your website, and stimulate others to do the same through simply discussing your operations, strategies, successes and failures. This is a foot-print that's hard to manipulate. Gaining mainstream coverage can (usually) only come with an established brand presence or exciting angle. If SEO clients don't have this in place, chances are that they will be swimming against the tide.

Topical Expertise

While engaging with the wider media is important, becoming a topical expert on your field is important too. If you gain topical coverage, you will most likely gain column inches to discuss topical issues when they come up. Search engines use this linkage data to establish your trust and (in the case of topical coverage) your authority on a subject area.

Content Strategies

Gaining media coverage has lots to do with business decisions made at board-level, but gaining media coverage, and in turn editorial citations, can be pulled off through effective content strategies and relationship building. If you're already immersed in your local community it's that much easier. Publishing studies, writing a blog, and making effective software tools relevant to your industry can all help if the content hits the spot. But, if you're getting started, you might have to send emails and make phone calls to get the ball rolling. Social media can also play an important role here, if done effectively.

Link Buying

It wasn't that long ago that Google dropped to toolbar pagerank of websites selling links. This, contrary to what some people think, hasn't killed the effectiveness of link buying. It has just changed the game. Now, buy-side companies should stay clear of websites that have an obvious link-selling footprint, and they should ensure that their links are placed within content too. The most cautious of link buyers will also ensure they are not given a link that would raise an SEOs eyebrows. This means perfect anchor text, and linking to a strange page, at a strange time, shouldn't be on the menu.

On-page Relevancy Factors

With publishing strategies being more frequently used to gain link equity, ensuring the effective flow of link equity up-stream to your most important pages can play a vital role in the success or failure of your SEO strategy. Using keyword permutations, derivatives and synonyms within website copy and meta data also helps to drive relevance for a main keyword set and help clients to tackle a wider keyword basket.

The Advantages and Disadvantages of an Automatic Garage Door

When you are deciding to buy a new garage door you certainly have a lot of choices to make. One of these choices is whether you are going to opt for an electrical door or a manual one. However before you rush ahead and decide, it is firstly essential that you set a budget. Without a budget you can not be sure of what you can afford, what will work, and what will not.

So how should you decide what budget is suitable for your new garage door? The first thing I would consider is how much you can afford to spend! An automatic door can cost around $5000, so if you do not have that kind of budget do not get too excited about the thought of an automated door, because you might not be able to afford it.

So if you can afford an automated garage, what are the advantages of having one? Well the first major advantage of one is the fact that when you drive into your drive you do not have to get out of you car, open the door, then get back in your car to drive it in. With an automatic garage door not of that isnecessary.

The advantages of automation does not stop there. It is not only great for the lazy people amongst us, it is also great for those of us who do not have the time to waste in getting in the house. With this door, we can fast-forward the the time it takes to get into the garage/out of the garage and where we want to be.

Another great benefit of this is security. Security is the most important aspect of your garage door, since it can effect whether or not your car is safe or not. With an automatic garage door you do not have to worry about security issues as much because many of these can be addressed through automation.

With an automatic garage door there are also disadvantages you have to consider. The first of these is obviously the cost that you will have to incur. Yes, ladies and gents, they do not come cheap compared to a normal manual door.

The next problem with automatic doors is when they dont work! Although this is not common it will happen. When this does occur you will have to call in an engineer which could be very expensive and you will also have to find an alternative in the mean time.These are all issues you will have to address and consider when you decide whether or not to buy an automatic garage door.

Whatever choice you make, make sure you are not just aware of what you get with the purchase, you also have to be sure you know what level of support you will attain after the sale. Remember that with garages things can go wrong, and you have to be prepared for when that day will come. Before you buy a garage I would consider reading reviews before hand.

10 Bone-Headed Mistakes Plasma TV Shoppers Must Avoid

Shopping for a Big Screen TV means avoiding lots of people trying to dazzle you with new technology.

You have to side-step slick TV salesmen talking about “DLP”, “EDTV” or “1080i”. You have to outsmart internet con artists selling “gray market” Plasmas. And you have to ignore bone-headed advice from Fred, the neighborhood know-it-all.

Mistake #1:.... Don’t Buy A “No-Name” Plasma TV!
The most important decision you can make when buying a big screen TV is to decide not to buy a “No-Name”. A device as complex as a LCD, Plasma or DLP TV must be manufactured with the finest components by dozens of expert technicians working in multi-million dollar plants. “No-name” companies use none of those.

Mistake #2: Never Trust A “Seeing Eye” TV Salesman!
If you walk into a TV showroom and don’t know EDTV from HDTV, some slick salesman will smile and eat you for lunch! Don’t let salesmen make choices for you, or you’ll end up with some outdated TV his boss wants to get rid of. Or you’ll end up with screen burn-in on your new Plasma when your son hooks up his Playstation 3; or suffer with a dim display in your brightly lit living room. Do a little research before you make a purchase; it’s not difficult.

(If you’re not familiar with some of the terms used above - DLP, EDTV, LCD - Google the "123 Guide To Plasma TV.com")

Mistake #3: Don’t Buy From A “No-Name” Retailer!
It’s important to buy your Plasma TV from a reputable dealer selling brand name merchandise. The return of a faulty 00 Plasma TV won’t bankrupt Wal-Mart or Sony; but could devastate a Mom and Pop electronics store. Try to make major purchases from a major retailer’s website; make sure they offer a good return policy and have brand name Plasmas at a discount price.

Mistake #4: Don’t Fall For Plasma Internet Scams!
We’ve all seen what look like great deals on Plasma TVs online. But exactly what is a great deal? It means getting GREAT MERCHANDISE at a GREAT PRICE. It’s not a great deal if you get CRAPPY MERCHANDISE at a GREAT PRICE! You don’t want your “new” Plasma to be a returned or refurbished item. Avoid “gray market” or “B stock” merchandise, and avoid sellers who aren’t authorized retailers.

Mistake #5: Don’t Play Video Games On A Plasma Television!
The chance of screen burn-in on a Plasma TV has been greatly reduced by improved technology, but not eliminated. Computer programs, video games, stock tickers and station logos can burn permanently into the screen, ruining your expensive TV. LCD and DLP TV screens cannot suffer screen burn-in, ever.

Mistake #6: Don’t Let A Know-It-All Pick Your TV!
Your neighbor Fred says he’s an expert on Big Screen TVs, and volunteers to help you buy one. Fred may be a good guy. . . he may even know the difference between DTV and DLP. But Fred may also be a Boob blowing smoke out the rear of his shorts. How can you tell? Rely on the only person you can trust to look out for your interests . . . you! Listen to Fred, but take him with a grain of salt . . . and do your own research!

Mistake #7: Don’t Try To Bring Home A Plasma TV By Yourself!
There was a time you could go to Circuit City, buy a 19-inch color TV, throw it in the back seat and take it home . . . those days are over! Shipping a Plasma TV to your home is the only sensible way to get it there; it’s too big, expensive, heavy and delicate to be shoved in the trunk of a car. Your retailer will arrange shipping for you; make sure that insurance and order tracking are included in the deal. Don’t sign for delivery until you’ve inspected your TV for damage.

Mistake #8: Don’t Install A Plasma TV Without Help!
A Plasma TV, although thin, is actually very heavy. A 50-inch Plasma TV can weigh over 160 pounds. Mounting a Plasma TV on it’s table stand is a three person job; call some strong friends over. The delivery people will put your TV on the curb, or in your living room, depending on what you paid for. They won’t install your TV on a wall mount, that service costs 0-0.

Mistake #9: Don’t Fail To Connect A Dolby Sound System!
You shouldn’t settle for the sound coming from your TV speakers. Attached to your TV, a Dolby 5.1 Surround Sound amplifier sends six separate channels of sound through speakers in front of, on both sides of and behind the viewer. Home Theater Systems start as low as 0 and go into the thousands; they include an amplifier, five speakers, wire and a sub woofer. Dolby 7.1 is even more advanced with eight sound channels.

Mistake #10: Don’t Forget To Budget For Peripherals!
For full enjoyment of your new Plasma TV, you’ll need lots of other stuff: HDMI cables for each peripheral, surge protectors, a TV stand or wall mount, a HDTV DVD player and digital cable for High Def broadcasts. You’ll also need a Home Theater System with at least Dolby 5.1 Surround Sound and a comfortable viewing area. I’m not trying to scare you . . . a modest system can cost less than 0, A good system between 0-00 and a Top-of-the-Line system 00 and up.

Well, there you have it . . . the 10 Biggest Bone-Headed Mistakes you could make when shopping for the perfect Plasma TV! Avoid them like the plague!

Good luck . . . I hope you find the Plasma TV that will thrill your family for years to come!

It’s as easy as 123!
