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 ...

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 ...

NTT Corp. (NTT) and Okayama University have developed a solution to the increasing problem of IoT signal interference by creating a topological ultrasonic circuit. Claimed as the first of its kind, ...

Ultrasonic double-sheet detectors distinguish between single and double sheets of paper, plastic, or metal foils to prevent waste or machine damage. The sensor operates by beaming ultrasonic sound ...

Since Tesla is equipping all its vehicles with the same sensor suite for self-driving, the company doesn’t have the luxury to install racks of sensors hanging around its cars like other firms ...
