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 ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...

A research team led by Dr. Shin Hur at the Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu), ...

Consider scrapyards: These dirty outdoor environments are filled with objects of every shape, size, and material. Controls on machinery that manipulate scrap need sensors to detect when conveyor belts ...

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 ...

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

I recently met Dr. Dave Horsley, CTO and co-founder of Chirp Microsystems. This is a company that was created in 2013 after incubating with Skydeck at Berkeley and the government-based SBIR program.
