Lets Renovate The World.A post every human should read!

This is a special post since today is a special day that is we celebrate this as the Science Day all over India.
Today apart from the mobile phones and Computers and other gadgets I thought of giving a post on the various new technologies that is developing around in the world.Some things maybe familiar to you but keep reading ,because , you may find some knowledge that may be unknown to you


Items Discussed here

• Hologrpahic TV
• Robotic Waiter
• Medical Mirror
• EyeBall Camera
• Finger Print Security Bike

1. Holographic TV

It seems to have been awhile since anything exciting has happened in the realm of the television market, with the long reign of standard plasma, DLP and LCD HDTV. In '08, there was the world's first Laser TV: a technology that utilized lasers to create an on-screen display many times more vibrant and crystal-clear than your standard HDTV.


Then, there were talks of OLED: a super thin screen that needs no backlight, slated to make LCD TV technology obsolete, currently under development by Sony and Samsung. Take a side-step into the upcoming world of 3D TV...it's not quite holographic, but makes objects appear in that quasi-3D way you've experienced in movie theatres...just without the glasses!


Many steps ahead, however, is Holographic TV. Currently nothing more than a speculation, there are theories as to what Holographic TV will be like and how it will perform.

There's not much information hypothesizing how a holographic TV set would work, but early ideas hint at a "screen" or a sheet of glass or plastic in which a hologram projector would draw the image through. Currently, it is thought to eventually provide a floating 3D "virtual reality" view of a motion picture image, in which the image and its components can be viewed from all angles, regardless of where you are standing in relation to the projection.

2.Robotic Waiter

A restaurant that opened this month in the eastern Chinese province of Shandong uses robots for waiters, boosting efficiency and providing further proof that human beings are superfluous. Machines don’t grumble over tips. And they can’t spit in your food.

The traditional hotpot eatery is staffed by more than a dozen automated servers, the distant and brightly colored relations of Star Wars’ golden droid C-3PO. The robots whir around the room on little bicycles carrying meat and veggies to be dipped by restaurant-goers into bubbling broth. Customers need not shout, weep or make obscene gestures to get their waiter’s attention. Every bot is equipped with motion sensors; all you have to do is get in one’s way and nab a plate of food.

3.Medical Mirror

One night in late 2009, Ming-Zher Poh and his roommate, Dan McDuff, asked some friends to sit in front of a laptop. Poh, an electrical- and medical-engineering graduate student at the Massachusetts Institute of Technology, was trying to transform the computer’s webcam into a heart-rate monitor. He hoped that his software would allow doctors to check the vital signs of burn victims or babies without attaching uncomfortable clips, and that it would make it easier for adults to track their cardiovascular health over time.

That night, the program wasn’t working in real time, but its measurements were near perfect. “Right away I knew we had something special,” Poh says.

A year and a half later, a large framed mirror embedded with a more refined version of Poh’s system sits in the MIT Media Lab. Behind the two-way glass, a webcam-equipped monitor is wired to a laptop.

Stand before the mirror, and the otherwise blank monitor projects your heart rate on top of your reflection.

When your heart beats, it sends a pulse of blood through your blood vessels. Blood absorbs light, so when more of it travels through the vessels, less of the light hitting your skin is reflected. A webcam can pick up those small fluctuations in reflected light, Poh says, and a computer program can translate that data into a heart-rate reading.

Researchers had tracked this effect with a high-resolution camera, but Poh wanted to use a simple webcam so that nearly every computer and smartphone could double as a heart-rate monitor. To make that possible, he developed an algorithm that could pick out the heart rate’s light pattern from all the other reflected light captured by a webcam. With help from McDuff, a grad student at the MIT Media Lab, Poh wrote code to process the data in real time, allowing the laptop to generate an instant heart-rate reading.

Poh plans to try to bring the mirror to market after he finishes his Ph.D. later this year. He says the system could be used to measure other vitals as well, including respiratory rate and blood-oxygen saturation, which should broaden its appeal. “This shows your inner health,” he says. “Maybe as people use it, they’ll say, ‘This is part of my identity. It’s not just how I look on the outside.’"

Name: Medical Mirror

4.EyeBall Camera

Do you want to see what is going on in your experiment, but can't because there's limited room to get your eye where you need it to see? Or is the object or pattern you want to view too close, too far or too small? Is laser safety an issue, or is the experiment enclosed or inaccessible to a human observer?

The Data Optics Silicon Eyeball (SiEYE) camera can solve your problems. Mini-sized, you can place the camera in a standard optical post mount, adjust its orientation and focus its removable lens. Use filters, pinholes, lenses and neutral density filters in front of it, as desired.

space

The Silicon Eyeball camera attaches via a standard FireWire cable to any PC or Mac with a powered FireWire port or via a USB cable to any PC with a USB 2.0 port. The real-time image can be viewed with the software provided and a 640 x 480 pixel snapshot can be recorded for later analysis or documentation.

Features:

• Real-time Preview Viewing and Still Picture Capture
• Standard Optical Post Mount
• Focuses from 1cm to Infinity
• PC and Mac Compatible (Mac OS 8.6-9.x, X, Windows)
• 640 x 480 Pixel Resolution
• Great, 24-bit Color Image
• High Speed FireWire (IEEE-1394) or USB 2.0 I/F

5.Finger Print Security Bike

The finger is placed on the fingerprint scanner mounted on the bike's dash board to start the bike engine

The fingerprint scanner compares the finger impression with the ones that were stored in its memory when the system was first installed on the bike.The bike owner has the permission to add or delete fingerprints thus allowing & disallowing people to ride the bike.

If the finger impression matches with those  stored in "Bikesafe-99" memory then access or permission is granted and you can start the bike.

If the fingerprint does not match, the bike does not start as it cuts of fuel supply ie no unauthorized person can ride the bike.
