A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

New surface-mount optical sensors increase vertical headroom, enabling more flexible encoder and position-sensing designs across industrial and consumer electronics.

Fig. 1 Overview of the OFN sensor. (A) Schematic diagram of the OFN sensing system; (B) Photographs of the output light when the sensor was untouched, (C) subjected to normal force, and (D) subjected ...

Cameras may soon see without lenses, and the change could be as profound as the leap from film to digital. A new imaging technology developed at the University of Connecticut promises to rewrite the ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...

Maintaining optical sorters can help a recycling system reach its optimum efficiency, a field supervisor says. Checking valves can be a critical maintenance step, since a broken or clogged valve leads ...
