Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

Machines are moving beyond single-point sensing. Multi-sensor fusion now delivers vision, ranging and inertial data. The ...

Optical-based smoke alarms use light instead. They are slightly better at detecting the large smoke particles created by slow ...

For as long as people have watched storms roll across the sky, lightning has inspired awe and fear. You can see the flash and ...

This oversight can lead to serious consequences. Automatic gates are powerful mechanical systems. When safety is not properly ...

Abstract: Failure mode (FM) recognition and remaining useful lifetime (RUL) prediction play pivotal roles in the field of prognostics and health management (PHM), particularly in regard to monitoring ...

Photoelectric sensors and light curtain sensors are among the most commonly used sensing devices in factories. Photoelectric ...

Cooking is the leading trigger for home fire alarms, yet the device you rely on to protect your family can become so annoying near the kitchen that you are tempted to silence it or take it down. The ...

Kitchen smoke alarms are supposed to protect you from the leading cause of home fires, not punish you every time you sear a steak. Yet one common placement mistake virtually guarantees nuisance alarms ...

Abstract: Conventional gallium arsenide (GaAs) photodetectors (PDs) encounter challenges in achieving high performance and sufficient photoelectric conversion efficiency with the near-infrared (NIR) ...
