The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

I recently completed designing an ultrasonic receiver that accepted signals in the 100- to 200-kHz band, downconverted the signal to an audio band, digitized it, and sent it to a remote computer. The ...

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 ...

Air leaks cost money. According to the U.S. Department of Energy (DOE), over $5 billion per year is spent on energy to power compressed air systems. The DOE estimates that optimizing these systems ...

Bats have been using sonar to navigate and communicate for ages, and now humans can do the same, thanks to lightweight and efficient ultrasound microphones and loudspeakers developed by physicists.
