The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Abstract: Conventional phased-array ultrasound can detect defects in nuts; however, accurately reconstructing their irregular shapes and precise spatial structures remains challenging. To faithfully ...

Abstract: This paper presents the development of an (Field Programmable Gate Array) FPGA-based system for ultrasonic detection of stratified flow, focusing specifically on the liquid phase. The system ...
