The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without ...

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: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

In this series I will be documenting my design and testing process for making a 3D printed arduino hexapod. This video sets up the basic premise of the project with a quick test of a servo controlled ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don ...

In a development that could transform how scientists study cancer, neurodegeneration and inflammation, researchers have ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...

Abstract: In view of the complex electric field, the internal field of power equipment will have different degrees of distortion, so that the local electric field outburst will be strengthened, and ...
