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 ...

In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is vertically ...

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), ...
