TDK Corp presents an angle sensor developed through GMR elements and focused on motor control of hybrid and electric vehicles. The angle sensor is embedded with features like a resolution as high as 0.35 and a smaller size compared with existing angle sensors that use a coil and a magnet. The angle sensor comes with a great combination of metallic disk, placed on motor shaft. Designed in circular arch consisting of four GMR elements inside each loaded with a permanent magnet on the rear side.
The metallic disk being oval in shape makes the distance between disk and sensor change as the shaft rotates, favouring changes in the magnetic field. The GMR elements detect those changes and determine the angles. When it comes to hybrid and electric vehicles, it is necessary to have an angle sensor that can detect the angle of a shutdown motor with the resolution of 0.5 to 0.8, according to TDK.

Radioactive waste has been giving nightmares to a number of people and in times like these when people could smuggle radioactive material for terrorist purposes, it becomes all the more necessary for us make sure the movement of radioactive material is curbed and detected at the earliest. Radiation detection technology, which has been developed by the Lawrence Livermore National Laboratory, could be used to detect radioactive material present in vehicles on the highways.
Adaptable radiation Area Monitor could help detect nuclear material at vehicular entrances. ARAM can detect nuclear material as tiny as a grain of sand and even when a vehicle is moving at a speed of 45 miles per hour. Another device is the RadTrucks, which can detect radioactive signatures emitted by uranium, cesium, and plutonium. ARAM can be installed in a number of places such as a portable detector in a SUV, vehicle monitor alongside motorways, pedestrian portable monitor, luggage or package detector, and the possibilities are endless.

If you thought humans were not meant to fly, think again, for a Swiss pilot has just flown across the English Channel. What’s new, you may ask. Well, he did not pilot an aircraft over the channel but piloted his own body, in short, he just flew!
All he did was, he fired up his attached jets and flew after leaping from a plane at the height 8,800 feet and then flew across the channel. He reached the other side in less than fifteen minutes. Probably, humans can now dream about flying anywhere they want, if they just attach a few jet engines to their backs.

If you like the classical pianist Chopin, you definitely would love to play the piano yourself. However, pianos are not only bulky but also very expensive. Since most of us can’t afford to buy a piano, we can go ahead and buy the piano hand gloves, which is a cheap and fun alternative to a bulky grand piano.
You don’t even have to go the piano classes and you could just start tapping your fingers wherever you want. The gloves will do the job of resonating melodious sounds from virtually nowhere. The Iwoot Piano Hand Gloves come with sensors at the fingertips and they translate the tapping into musical notes. This would actually mean, you could go ahead and start playing music in air without carrying any instruments.

Raytheon is one of the most famous companies that have been conducting research on exoskeletons. In fact, they are the leaders of the exoskeleton industry. Their latest contribution to this realm is a biologically inspired aquatic exoskeleton. These robotic suits enhance the user’s strength and allow him or her to mimic the movements of penguins and dolphins.
If you remember a certain episode where Tom swam in the water like various aquatic animals, you can do just that, but there wouldn’t be a mer-Jerry to eat. These exoskeletons will allow swimmers to achieve speeds of 1m/s and also a top speed of 1.5m/s. It emulates two types of biological propulsion, which are the body and/or caudal fin locomotion and median and/or fin locomotion.

You might always have dreamt of owning your own toy sentry and keeping all worries at bay.� The Rovio, one of WowWee’s finest Webcam-Equipped Robotic Sentry might sound like a science fiction robot but this product is made closer to reality. The Rovio comes with a great package of Audio and high-resolution.
640 x 480 Webcam to stream back live video in MPEG4 format is a great feature and further, the Rovio consists of two-way microphone and a speaker enabling real-time interaction with subjects. Three wheels support its chassis, providing 360° movement and its camera boom extends to its surroundings. It operates for two hours and requires a PC running on Windows XP or Vista or Macintosh with a Wi-Fi card, a broadband Internet connection, router, or other type of wireless access point.

The Department of Homeland Security have developed a new anxiety-detection technology designed to detect unusually high biological fluctuations in humans at airport checkpoints like changes in breathing patterns, increased heart rate, etc. Our inability to know when someone is deceiving us has enormous consequences in the fight against terrorism. These bio scans may help authorities to spot dangerous people.
This may remind one of the redundant and annoying saying “prevention is better than cure”. You might have a doubt nagging at the back of your mind that a person might shows signs of anxiety the moment he walks through a checkpoint like quickened heart rate and heavier breathing, and fluctuations in body temperature.
