A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).

Peanut Butter Blossoms. As the story goes, a woman by the name of Mrs. Freda F. Smith from Ohio developed the original recipe for these for The Grand National Pillsbury Bake-Off competition in 1957.
DARPA Shredder Challenge 2011 was a prize competition for exploring methods to reconstruct documents shredded by a variety of paper shredding techniques. The aim of the challenge was to "assess potential capabilities that could be used by the U.S. warfighters operating in war zones, but might also identify vulnerabilities to sensitive information that is protected by shredding practices ...
The sensor circuit is supplied with constant current. A distinguishing feature of the IEPE principle is that the power supply and the sensor signal are transmitted via one shielded wire. Most IEPE sensors work at a constant current between 2 and 20 mA. A common value is 4 mA. The higher the constant current the longer the possible cable length.
