Itasca, Ill. — Knowles Acoustics introduces an ultrasonic acoustic sensor (UAS) to detect/receive ultrasonic sound in air. The UAS uses the latest micro-electromechanical (MEMS) technology to provide ...

Ultrasonic sensors use sound waves above 20 kHz to measure the distance from the sensor to a specified target. The sensor transmits and receives sound via a ceramic transducer that acts like a ...

Ultrasonic time-of-flight (ToF) sensors are embedding more powerful on-chip processors with higher computational capability to run a wide range of application algorithms while offloading the system ...

Photoacoustic imaging, a technique for examining living materials through the use of laser light and ultrasonic sound waves, has many potential applications in medicine because of its ability to show ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

Toposens, a manufacturer of safety equipment, announces the launch of a 3D ultrasonic collision avoidance sensor for automotive and industrial vehicles. Called ECHO ONE, the product is based on ...

Consider scrapyards: These dirty outdoor environments are filled with objects of every shape, size, and material. Controls on machinery that manipulate scrap need sensors to detect when conveyor belts ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...
