A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track ...

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 ...

The need for accurate and reliable level measurement systems is increased by the demands of advanced automated processing systems, more stringent process control and strict regulatory requirements. By ...

The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...
