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 ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

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 ...

Some kinds of data should be encoded onto an inaudible, near-ultrasound layer placed on top of normal, audible sounds — a process that could rapidly scale Internet of Things (IoT) adoption, says ...

The UK’s LettUs Grow has developed a unique method of growing plants with sound and water aimed at boosting sustainable production in horticulture. The Bristol-based company supplies vertical farm ...

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 ...

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 ...
