Ultrasonic fingerprint sensors are taking smartphone security to the next level, offering reliable and fast unlocking even in less-than-ideal conditions. If you’re interested in experiencing ...

Ultrasonic sensors are used across a variety of industrial areas, as they measure distance simply via calculating the difference of time between transmission and reception of signals. However, ...

To address this problem, we propose a ultraprecise simultaneous localization and mapping (SLAM) positioning method, namely, preciseSLAM, which tightly couples LiDAR, inertial measurement unit (IMU), ...
