Generator implanted in shoe sole to generate power



Assistant professor of electrical engineering at the Louisiana Tech University (La Tech), Dr Ville Kaajakari, has invented a technology that is able to produce power from a small generator, which can be implanted in a shoe sole.

He said that, MEMS are small intelligent devices that merge computer chips with micro-components such as gears, sensors, mirrors, flow-channels, and actuators.

This new initiative was invented by Dr Kaajakari at La Tech for the purpose of Micromanufacturing (IfM). Now, IfM is based on new voltage regulation circuits that can efficiently alter a piezoelectric transducer into voltage that can be utilised for charging batteries or for directly producing electricity that can be further used by electronic gadgets.

According to Dr Kaajakari, this technology is beneficiary for people such as hikers who would want to use their emergency location devices while hiking; or on a more general note, it can also be utilised to power portable electronic gadgets without making the use of batteries.

Energy harvesting is the smartest way to power MEMS sensors and other devices such as a GPS system. Unlike the regular ceramic based transducers, the piezoelectric transducer is soft and strong, thereby, easier to take the place of a regular heel shock absorber without disturbing the user.

Dr Kaajakari concluded by saying that, “I am planning to increase the power levels to a point wherein this type of generators could also recharge portable electronic gadgets such as mobile phones.”

Google searches for "hung Parliament" have been soaring, and if you put the word in the box, you will find both the Tories and an electoral-reform group called Power2010 advertising alongside your search outcome - along with a certain lingerie retailer.
The Conservatives are using their latest party election broadcast to warn of the dangers of such an result but there's also a number of websites springing up with the aspire of bringing it about.
Of course, it's nigh-on impractical for individual voters to make a hung Parliament happen, because we simply do not have adequate information.
yet in a three-way marginal, unless we identify something about how our neighbours plan to vote, you could find that voting for your first choice might end up handing success to the candidate who was third on your list.
But some web evangelists believe they can solve this predicament by using the net to build communities with the information to act together to change the electoral outcome.
One site, Count My Vote, asks you to name your favorite candidate - with a guarantee of ambiguity - and then tells you how other people in your constituency are voting so you can work out whether it's worth voting tactically.
But when I looked, I was the first in my constituency to use the site, so it needs the network effect to kick in pretty rapidly if it's to make a difference.
One more site, Hang'em, describes its mission thus:
"The aim of Hang 'em is not ideological. It is not about voting for a candidate whose views you agree with (and is likely to lose). It's about voting for people with integrity and character - the more independent the better - including Tories and Labour candidates with a record of rebellion."
So the idea is to recognize independent-minded candidates with a chance of winning and then rally people behind them. Already there are recommended candidates in most constituencies, and a Facebook group which the organisers believe will be the main way of spreading the message.
But even in this brand-new political movement, there are already splits and rows. Some are angry that any Labour or Conservative candidates are being put forward as suggested candidates; others are rowing over whether a Lib Dem/Labour or a Lib Dem/Conservative union would be better.
Of course, for sufficient of people all this is irrelevant anyway because they live in places where the outcome of the election is not really in doubt.
The Electoral Reform Society has a versatile site called Is Your Election Over? which maps constituencies and tells you whether your vote is likely to make any difference.
Right now, the web is proving very good at providing voters with a mountain of information about the parties, their candidates and their policies, with sites like Vote Match helping you make up your mind how to choose from the menu according to your personal policy tastes.
But, however keen the evangelists for a hung Parliament may be, they're going to have to draw huge crowds to their websites over the next 10 days to have a hope of making any difference to the outcome. And, according to the polls right now, they don't even need to bother - it will happen anyway.

Sony to stop selling floppy disks from 2011



Sony has signalled what could be the final end of the venerable floppy disk.
The electronics giant has said it will stop selling the 30-year-old storage media in Japan from March 2011.

Earlier this year Sony stopped selling the disks in most international markets due to dwindling demand and competition from other storage formats.

The slow death of the "floppy" or "diskette" began in 1998 when Apple decided not to include a floppy drive in its G3 iMac computer.

Since then various other firms have stopped support for floppy disks, including computer giant Dell in 2003.

Computing store PC World stopped selling them in 2007.

However, Sony has continued to sell the disks, and continues to ship them in the millions.

Now, the firm - which claims to have produced the first 3.5in (9cm) disks in 1981 - has decided to halt sales completely faced with competition from online storage and portable USB drive

Nokia launches first open source Symbian phone


The first handset to use the Symbian operating system since it became open source has been announced by Nokia.

The N8 phone has a 12 megapixel camera and allows people to record and edit High Definition video clips, as well as watch web TV services.

Analysts said the phone was a "pivotal device" in efforts "to make Nokia's high end phones credible again".

It is also a chance for Symbian to prove itself alongside Google's Android operating system and Apple's iPhone.

Despite being the world's most popular smart phone software, Symbian has lost "mindshare" against more high-profile software, according to industry experts.

Analysts at CCS Insight described the Symbian 3 software as "evolutionary not revolutionary" but said it was a "key first step if it proves reliable".

Cinema support

It is the first version of the software since the Symbian foundation announced that it had made its code open source in February.

The Foundation - which includes Nokia, Motorola and Samsung amongst others - gave away the code to developers for free in the hope that it would help speed up the pace of improvements. Any organisation or individual can now use and modify it.

The software in the N8 allows the phone to have multi-touch and multi-tasking, meaning more than one application can be open at any one time.

The device will be Nokia's flagship smartphone. It can be plugged into home theatres and supports surround sound as well as high-quality video.

Social networks, such as Twitter and Facebook, can be displayed on the home screen in a single application.

Lee Williams, executive director of the Symbian Foundation, said he was "stoked" that Nokia had chosen to use the operating system on its phone.

The phone will ship in the third quarter of 2010, following delays.

NASA's android astronaut assistant prepares for launch


NASA is preparing to send its first humanoid robot into space. Robonaut first twitched to life in September 1999 and, after a decade of tests, the 140-kilogram R2 model will finally be launched to the International Space Station on the space shuttle Discovery's last mission in September.

With continual maintenance work needed on the ISS, the idea is to give the crew an assistant that never tires of undertaking mundane mechanical tasks - initially inside the craft but later outside it too.

R2 comprises a humanoid head and torso with highly dexterous arms and hands. It was developed by NASA in conjunction with roboticists at General Motors. After being bolted to a piece of ISS infrastructure, R2 can use the same tools, such as screwdrivers and wrenches, as the astronauts.

One reason for the mission, NASA says, is to see how Robonaut copes with the cosmic radiation and electromagnetic interference inside the space station.

The main challenge, though, will be to ensure the robot is safe to work with, as tools can fly off easily in microgravity, says Chris Melhuish of the Bristol Robotics Laboratory in the UK. "Robots have to be both physically and behaviourally safe," he says.

Athletes' sweat test road to glory



Track athletes in Ireland preparing for the 2012 Olympics have been testing a device designed to improve performance by optimising their hydration levels during training.

Dehydration can undermine both mental and physical performance, including causing tiredness and cramping.

Analysis of sweat samples taken after training is unreliable because the key compounds oxidise when in contact with air. "It does not give a real measure of what is happening during exercise," says Fernando Benito Lopez at the Clarity Centre for Sensor Web Technologies at Dublin City University.

To tackle the problem, Benito Lopez and colleagues have developed a device that assesses hydration levels while athletes are training. It is based on an absorbent pad strapped to the athlete's body, which draws sweat through a narrow channel containing pH sensors.

Skinput Touch Interface




Skinput is a new futuristic interface currently being developed by Microsoft and Carnegie Mellon University. The system is the combination of two technologies, the ability to detect ultralow-frequency sound, and a microchip-sized projector.

This amazing interface can recognise which parts of the body has been tapped using the sounds that is created by the sin, bone and skeleton. The Skinput technology uses a band which is strapped on to the arm. The armband contains piezoelectric cantilevers, or sensors that measure pressure, acceleration and force.
The actual interface is beamed onto the skin using a pico projector similar to those found in mobile phones. The applications for such technology are endless but major ones include gaming systems, phones or PC controllers.

US General Demands Robot Army, Counts 122 Lives That Bots Could Have Saved



Robo-grunt There was something unnerving about how it kept asking about John Connor... via California Science and Technology News

Like most Army commanders, Lt. General Rick Lynch says that he needed more troops in Iraq, and that they would have saved the lives of men lost under his command. Unlike most commanders though, Lynch isn't demanding flesh and blood soldiers, but steel and rubber robotic infantrymen.

Speaking at the Association for Unmanned Vehicle Systems International conference, Lynch said that robot systems already in place could have saved 122 of the 155 men who died during his time in Iraq.

Lynch's concerns hold particular weight, as he has both the combat experience of leading the Army's Third Infantry Division in Iraq, and the academic experience of earning a Master's Degree in robotics from MIT.

Echoing similar statements he made in August, Lynch claims that deploying remotely, or autonomously, navigated ground vehicles could have lowered casualties as a result of IEDs, and that robotic infantry could have replaced humans on dangerous surveillance missions.

Some robot infantry had been deployed to Iraq, specifically the SWORD gun platform, but the Army severely restricted their use over safety concerns.

Lynch went even farther than most in his talk, demanding the implementation of autonomous, armed robot systems. He countered other Army critics, saying that he believed the current level of technology was advanced enough to overcome problems with autonomous robots shooting the wrong people.

"There's a resistance saying that armed ground robots are not ready for the battlefield. I'm not of that camp," Lynch said.

Development of Futuristic Super Lightweight Electric Vehicle by TEIJIN




Comparatively unknown to this industry, Teijin Group showcased a revolutionary electric concept vehicle weighing only 437 kg, less than half the weight of conventional electric vehicles. The PU_PA EV as company calls it, is made based on Teijin proprietary equipment and technologies which include fiber composites, polycarbonate resins as well as bio-derived polyester. The name of the PU_PA which is a reference to metamorphosis is an embodiment of company’s vision of what a vehicle will look like in five to ten years time. The vehicle is capable of running at a 60 km/hr with a cruising range of 100 km.
Key contributing factors to PU_PA’s weight lessening are incorporation of carbon fiber composite in its body core structure and windows that are made of polycarbonate resin with heat absorbing function weighing half as much as glass as well as modularized parts made with single-piece molding, resulting in reduction in total parts which is only 20. Teijin biotechnology know how has contributed to making of interior items such as seats, floor mats, etc., with bio-derived polyester. From the ecological side of things, the company used its metal-toned TEFLEX PET film, as an substitute to chrome plating, as well as low-noise tire cord made of TEONEX polyethylene naphthalate (PEN) fiber. The PU_PA uses a multi-device communication using CELL FORM two-dimensional communication sheet. This may not be The ultramodern vehicle that some of us have in mind but it is certainly a good marketing tactic by Teijin in showcasing the innovative technologies and know how that company possesses.
