But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

Expensive spinning lidar units can be found atop and around Level 4 autonomous vehicles, such as those from Cruise and Waymo.

Diffuse or Reflective sensors have the transmitter and receiver packaged in the same housing. When a target enters the sensing range of the device, the ultrasonic waves are reflected back to the ...

like with this ultrasonic flow meter, could be a big deal for DIY projects and the trades in general. The principle behind the sensor [ItMightBeWorse] is working on is nothing new. He discovered a ...

These sound waves are then focused on a target and the echo is read by sensors to determine ... using four different ultrasonic wave types: (1) longitudinal wave, (2) lateral wave on the surface ...

The chip supports pulsing ultrasonic transducers, with excitation voltages of up to 50V, and has high gain and low noise receivers, for increased sensitivity to ultrasonic echoes. The chip is ...
