To implement a motion control system, it is necessary to sense the movement of a device that is rotating or travelling along a straight line. This requirement is common in a growing number of ...

Accelerometers are increasingly ubiquitous in consumer devices and industrial applications, largely as a result of the advances in MEMS manufacturing techniques that have allowed the sensors to become ...

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Noncontact motion sensors detect speed and direction of motion using a CMOS video imager. In many printing, packaging, and general web applications, it is often necessary to know whether the web is ...

Readers with long memories will remember the days when mice and other similar pointing devices relied upon a hard rubber ball in contact with your desk or other surface, that transmitted any motion to ...

Can one sensor handle fast motion, low light, IR scenes, and tiny devices at once? A new 5 MP design claims it can — here is more.

A silicone strain sensor glued to a rubber glove bends easily with the wearer's finger. The amount of light transmitted by the fiber changes with the bending. Disclaimer: AAAS and EurekAlert! are not ...

Entanglement is usually considered to be a prime example of the fantastic challenges which our imagination must master when dealing with quantum mechanics, the non-classical physics. The properties of ...
