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.
