White light scanning interferometer (WLSI) systems are also used in RDL process monitoring. These methods rely on ...

The present paper proposes a highly innovative obstacle detection sensor, combining both passive and active optical devices and based on a new concept of optronic system. It is specifically conceived ...

This post will share some tamper detection ... and sensors that can assist in the effectiveness of tamper detection. Now let’s go into a bit more detail. The most common tamper detection system ...

This work performs obstacle detection and attitude estimation for a small quad-rotor by using low-cost sensors, namely, a Sonic Ranging Sensor (SRS) and an InfraRed Sensor (IRS), widely used in mobile ...

Traditional time-difference methods were found to be less effective for calculating water flow velocities using the ... the mobile ultrasonic stratified flow velocity measurement device was feasible ...

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.
