Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

This study comes as the number of confirmed exoplanets from NASA has reached 5,839 with 1,738 being designated as super-Earth (radii between Earth and Neptune/Uranus) and 213 being designated as ...

The Circular Ring 2 is set to arrive in four finishes this spring boasting specs and a starting price comparable to the best smart rings available in 2025. Here's everything you need to know about ...

With linear ultrasonic welding, parts typically have to be around 3.2 millimeters thick. By comparison, torsional welding can achieve welds on parts less than 2.5 millimeters thick without read ...

Professor Dong Shuxiang's research group has developed a novel symmetric-actuating linear piezoceramic ultrasonic motor ... (B 3) modes to produce two symmetrical elliptical movement trajectories in ...

The difference is very simple. A linear-polarized antenna is designed to concentrate RF energy in a narrow plane. Imagine a strong water hose with a nozzle that has a narrow slit in it. Water would ...

In plastic welding, conventional LINEAR ultrasonic welding heads are arranged vertically and use a converter, operating at between 20kHz and 40kHz together with a booster, to increase the amplitude.
