In a recent development, NTT Corporation unveiled the “first” gigahertz ultrasonic circuit that utilizes topological insulator principles, indicating a new era in ultrasonic communication technology.

The first sensor a robot usually gets fitted with is an obstacle detector. It may take three different forms, depending on the type of obstacle you want to detect and also — indeed, above all — on the ...

INTROTEK ® Non-Invasive PAD (Point-Air Detection) Sensor provides a reflective ultrasonic signal from a single contact point, making it the ideal air detection solution for fluid-handling cassette ...

The circuit operates using a pair of ultrasonic transmitter and receiver modules which are used to detect the person. When the person is detected (the person is in the front door), the doorbell is ...
