SICK, one of the world’s leading manufacturers of sensors, safety systems, machine vision, encoders and automatic identification solutions for factory and logistics automation, announced the launch of ...

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

Ken-ichi Nomura (Researcher) and Hirobumi Ushijima (Leader, also Deputy Director of the research center), the Advanced Surface Processing Team, the Flexible Electronics Research Center (FLEC; Director ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Gill Sensors announces the new range of miniature fuel, oil and coolant level sensors, planned for launch at AUVSI Unmanned Systems North America 2010. The miniature sensors feature Gill's new ...
