[Mike] built a sensor rig to measure projectile speed. The setup uses a tunnel with two sensors in it. Each consists of a laser diode on one side focused on a photodiode in the other. The two are ...

The wheels of a moving vehicle can move at different speeds, with some turning faster than others. This can cause a loss of steering control and compromise safety on the road. To mitigate this, speed ...

Advances in embedded systems and sensors have enabled efficient, intelligent surveillance solutions that improve safety and ...

Electrical engineers at Duke University report they have built a record-setting pyroelectric photodetector that uses trapped ...

Novotechnik’s new Vert-X 05E Series of dual angle/speed sensors include easy mounting in small and narrow spaces with a body depth of 5 mm and mounting flanges with metal inserts. Sensors feature ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Future motorcycles and other vehicles may have sensors that read roadside speed limit signs and electronically intervene to limit the vehicle’s speed. Traffic Sign Recognition (TSR) is already ...

Conventional CMOS image sensors are not suitable for low-light applications such as fluorescence, since large pixels arranged in a matrix do not support high readout speeds. A new optoelectronic ...

Investigators trying to determine why Air France Flight 447 broke apart in a violent storm over the Atlantic are looking at the possibility that speed sensors - or an external instrument key to ...
