Bluetooth Technology Helps Injured Vets

Bluetooth is usually associated with cell phones and laptop computers. But the short range wireless communication provided by Bluetooth technology has been successfully used in another arena: making better prosthetic limbs.

Two injured veterans who underwent double leg amputations above the knee have benefited from the new type of artificial legs. Marine Lance Cpl. Joshua Bleill and Army Lt.Col. Gregory Gadson now use the prosthetics fitted with Bluetooth to achieve a greater range of walking motion and better endurance.

The Bluetooth devices, located in each ankle, communicate to coordinate motion between the legs. The system responds to muscle movements in the thigh and works to create a smooth motion with good balance.

Right now, the patients are able to walk on their prosthetic limbs using canes to aid their balance. Doctors hope that this technology will eventually allow double amputees to walk even without a cane.

Working Out the Wii Way

It used to be that video games were for couch potatoes.

Then the Nintendo Wii came along. The Wii moved video gaming up a level in terms of physical action, using a wireless controller to simulate actions like throwing, punching, or swinging an object.

The first time you tried playing Wii Sports, you might have noticed that you were a little out of breath. You were having so much fun playing tennis, bowling, baseball, or boxing that you didn’t even notice you were working out!

Now, Nintendo has chosen to emphasize the physical benefits of Wii gaming by introducing the Wii Fit system. This system uses a small, flat box (the Balance Board) that senses your weight distribution and motions and wirelessly sends the information to the gaming box. While you perform exercises such as aerobics, dancing, and balancing, the Wii makes measurements and gives you feedback.

The bad news? Wii Fit is not yet available to American gamers. It has been a huge success in Japan, and Nintendo intends to release it in the U.S. this year.

The Switch to Flash and the Death of the Hard Drive?

Hear that loud whirring sound from your laptop? That’s the fan working overtime to try and cool down your overheated machine. This massive heat dissipation is caused by many culprits, and the main one is your hard drive.

What’s on your hard drive? It’s a bunch of spinning disks, and it’s those that drain so much power. But several recent advances in Flash technology innovation mean that the spinning disks may soon turn into a relic of the past.

A few years, the introduction of the NAND flash memory looked like it would signify a revolution in computer storage, with a lot of memory packed into a small space. But there was one drawback: data transfer rates between devices were sluggishly slow.

Now, a partnership of Intel and Micron has come up with a potential cure for the bottleneck. Their joint venture recently released a new flash drive with data transfer rates up to 200 MBps (reading) and 100 MBps (writing). That’s about 5 times faster than traditional flash technology.

What else can you power with solar energy?

Solar powered device 1 Taking advantage of solar energy means dedicating a significant size of your roof space to large, unwieldy solar panels, right?

The answer is, of course, no. You can buy solar panels in all sorts of sizes, ranging from a square foot or less to an entire yard-size. Of course, if you want to get all of your home power from solar energy, you’ll have to invest in a large span of panels. But if you’re looking for a smaller, cheaper place to begin your relationship with the sun, why not start by powering your personal electronics?

Several companies now offer solar power packs that are small, attractive, and portable. They’re meant for powering devices like CD and MP3 players, speakers, and cell phones. While prices can range up into the hundreds for elaborate systems, some companies like Solar Style offer small packs for as little as $27.99.

How do they do it? We start with the most essential item: the photovoltaic cells that capture energy from the sun. In fact, the sun isn’t even necessary; light from any source can be converted into usable energy. Of course, the more intense the light, the more energy you will store.

The next step is to store the energy. Solar packs have an on-board battery that acts as your savings account for the energy you collect. Leave your power pack collecting light whenever you can, and save the energy for later. (But don’t turn on a houselight specifically to shine on the pack – that’s just being silly!)

Now, the only remaining step is getting that power to your electronic devices. All you need for this is the right connector. Most purchase options include some connectors for cell phones and music players. If your device has an unusual power connector, you may have to buy one separately. The point is, you can power any device this way, as long as you have the connector.

At these prices, there is no reason not to purchase a solar power pack. The devices are small and convenient, and can eliminate the need for an outlet – thus allowing us to truly enter the wireless age. In addition to convenience, these gadgets are green. Instead of using expensive electricity from the power grid, which increases carbon emissions and dependence on foreign oil, you can tap into a free, renewable energy source that already surrounds you.

Google Street View: Useful Tool or Attack on Personal Privacy?

Street sample So you want to meet a few friends at a trendy restaurant in downtown San Francisco. Trouble is, you don’t remember the exact location or even the name. How are you going to tell your friends where to meet you?

Solving this dilemma used to require a long quest to track the place down. Now you can make that journey virtually, by clicking on Google Maps’ new Street View feature.

Street View is available for dozens of major cities across the U.S. It doesn’t cover all of each city. But in covered areas, it provides access to a 360 degree street-level view from almost any point on the block. All you need to do to locate your restaurant is to take a "stroll" down the street and check out the surroundings until you find it. Map

Here’s an idea for your next vacation: In order to capture everything you see, keep a camera rolling every time you walk down the street. That way you’ll have a virtual record of every intersection, every market, every coffee shop you pass.

That’s essentially what Google has done. They hired Immersive Media Corp., out of Calgary, to provide their high-resolution digital photographs. This meant mounting a camera on a car and driving down every single street that is covered.

It’s hard to deny that this is a really useful feature. Knowing what your surroundings look like is invariably helpful in finding your way. Everyone from the average citizen to local police officers can find a use for this.

But not everybody is so thrilled about the idea.

Suppose you find that restaurant by noticing the sign out front. But that’s not it. You can also see the people sitting at the outdoor tables, including one who looks a lot like your significant other. And who is that sitting suspiciously close to them…?

You get the idea. In addition to shots of the street, the images also capture people, cars, windows, yards, and all sorts of things that opponents say constitute a huge breach of privacy. And since there’s nothing we love more than privacy breaches, there are a bevy of blogs on the Internet where users have posted "items of interest" found on Street View. These show possible drug deals, people caught in embarrassing positions, and views of homes through windows.

Google defends its venture by saying that it offers protection for the embarrassing lack of privacy. Compromising images can be reported, after which they will be removed or altered. And of course, the images aren’t live; they were collected many months ago.

The bottom line? Lawsuits are inevitable. All it will take is a "discovery" on Google Maps that leads to a divorce, loss of job, or a burglary. Will this remove the Street View feature forever? Or will it simply force Google to be more careful about what it shows in its virtual Universe?
