A Biometric bracelet recognizes it’s wearer just by the electrical impedance!

It’s a device that measures someone’s unique response to a weak electric signal could let medical devices such as blood-pressure cuffs automatically identify the wearer and send measurements straight to his or her electronic medical record.

This is how it works:

One electrode on the device sends an alternating current through its wearer’s wrist to a second electrode. While the current is passing through the wrist, the electrodes detect the wrist’s resistance and reactivity, which are components of impedance. A processor extracted seven features from the electrode pattern, and the team then used a series of five readings per user to train the processor to recognize a given user’s bioimpedance profile.

Syyn Labs.

Um..I have been thinking to write some posts on the companies which come forward with their uniqueness into the market.Here is the one called “Syyn Labs”.

Syyn Labs

Syyn Labs

Syyn Labs is a Los Angeles-based organization that fuses the worlds of technology and interactive sciences with artistic mediums to design and construct visually dynamic spectacles that inspire thought and provoke conversation.

They really do some crazy stuff with a team having engineers,artists and what not! They got real famous after a viral(not a true virus 😛 ) video on youtube.

Here is the video for you.

Forgotten heroes of technology-2

John Cioffi:Father of DSL

John Cioffi

John Cioffi

Not one to blow his own horn, Cioffi shies away from publicity. But by all accounts, the Stanford professor was intent on coming up with a way to deploy broadband over copper wires and developed asymmetrical digital subscriber line (DSL) technology. He left Stanford in 1991 to found Amati Communications Inc. He has since returned to Stanford, where his research focuses on Dynamic Spectrum Management (DSM).

 Gary Thuerk:Father of spam

Gary Thuerk

Gary Thuerk

In 1978, an overly aggressive sales rep from Digital Equipment Corp. sent out a pitch to several hundred names on an early ARPANET mailing list. Not only did Gary Thuerk get flamed, the feds running ARPANET threatened to throw him in jail. How times have changed. Today, 80 to 90 percent of all email is spam and nobody seems to know where it’s coming from or how to stop it. As for Thuerk, he’s at HP, still selling computer gear. Is Thuerk embarrassed about unleashing the scourge of spam on the world? Not really. “I’m the first one to do it, and I’m proud of it,” he says.
Here is some cool stuff about the first spam ever!

 Doug Engelbart:Father of the mouse

Doug Engelbart

Doug Engelbart

Engelbart is an early Internet pioneer. In 1969, ARPANET’s first transmission was between nodes at Leonard Kleinrock’s lab at UCLA and Engelbart’s lab at Stanford. A philosopher, scientist, and inventor, he’ll always be known as the father of the mouse, which he patented in 1970. He never received any royalties however. His patent expired in 1987, before the personal computer revolution. Today, at 83, he heads the Doug Engelbart Institute.

New user interface device by MIT

Wow! man. I seriously got a shock by looking at this. a small metal orb floating in free space that users can manipulate by moving around and placing in mid air. Suspended by a highly tuned electromagnetic field, the orb really does seem to levitate, and the degree to which the system keeps the ball stable even as it is moved around on all three axes is pretty mind-blowing. The ball floats until it is moved, and when placed in a point in space it stays there. And with an added layer of software surrounding it, the orb becomes a tool for all sorts of applications.

The trick to all this is a precision electromagnet fitted to a moving actuator above the ZeroN’s workspace. The electromagnet can move around the space above and rapidly adjust its magnetic pull or resistance based on where the ZeroN is in space, a value that is measured every few milliseconds by an array of IR cameras. So while the ZeroN appears to float as if in defiance of gravity, the setup is purely mechanical. All it really requires is a very precise electromagnet and the right software to keep the orb stable.

But,as usual nothing is too easy! Here is the video.I would like to ask you a question at the end of the video which I didn’t get how it works….

Almost at the end, how did the small metal orb tackled with the gravitational force(I am some of them who believe that gravity doesn’t exists!) when it was made up side down?

Control stuff by brain waves..!

Firstly,I guess you need to know more about the brain waves.The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment (such as an EEG), measuring electricity levels over areas of the scalp. The combination of electrical activity of the brain is commonly called a Brainwave pattern.

Find the more info about this here… You may also google it… 😛

Coming to the main topic by using these brain waves we can control the objects….You can understand this more easily by checking this video out….

So,in other words we can say that we ourself are controlling the television set without remote.But,only with our thought..!!
