Proximity sensors, which detect when your ear and cheek are about come into contact with a a touchscreen, have been a standard part of modern day smartphones. Elliptic Labs believes it has come up ...

Optical Proximity Sensor The optical proximity sensor consists of an LED that’s ON, a photodiode, a transimpedance amplifier (TIA). and a light shield with a window.

San Jose, Calif.—Avago Technologies has developed an ultra-thin integrated optical proximity sensor for use in a wide range of portable consumer electronic devices, and personal computers. Avago's ...

The optical proximity sensor requires one rectangular black shape or two large holes on the screen, these sensors detect when users are in call mode so the touchscreen can be deactivated.

Integrating an optical touch switch in their compact, surface-mount packages, the SFH7740 and SFH7741 proximity sensors use distance measurements to detect a mobile device’s operating ...

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 ...

Elliptical Labs has found a way to replace a staple of smartphones — the hardware optical proximity sensor — with an ultrasound software solution.

This development is expected to help streamline smartphone designs and bring down costs by eliminating the need for a traditional optical proximity sensor.

Able to detect the presence of objects from a distance of 0.04 to 24 in. by means of a reflective sensor, the OPB720 series optical-proximity sensor features a synchronized infrared LED and ...
