Linear guideways with built-in encoders are transforming precision motion systems by combining guidance and feedback in one ...

Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

Generally when a game console with an optical drive stops reading discs the first thing that people do is crank on the ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: Incremental optical encoders are widely used as photoelectric sensing components in direct current motor servo systems, but their inherent susceptibility to optical interference ultimately ...

Quantum optics is the study of how individual quanta of light, known as photons, interact with atoms and molecules. This includes studying the particle-like properties of photons. Photons have been ...

The RE200 Series encoders use readily available low cost industry standard connector systems with integral connector interlocks. GOLETA, CA – September 24, 2007 – RENCO ENCODERS INC. introduces a Low ...
