Abstract: Local Positioning Systems (LPS) have emerged and spread during the last decade, mainly associated to the development of location-based services in those environments where GPS (Global ...

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 ...

Abstract: Barium titanate (BTO) nanoparticles-based miniaturized, three-dimensional pyramid receiver is presented for wireless ultrasonic power transfer. A single pyramid ultrasonic receiver can ...

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 ...

To overcome these limitations, researchers are now considering the use of ultrasound as a new wireless power transfer technology. Ultrasound has the advantage of being human-friendly and less absorbed ...

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 ...
