A polymer corrugated diaphragm-based fiber-optic Fabry-Perot (FP) interferometer is proposed as an ultrasonic sensor and directly fabricated on an optical fiber tip by direct laser writing via ...

This paper introduces a novel method for arm flexion/extension angles measurement using wireless ultrasonic sensor network. The approach uses unscented Kalman filter and D-H kinematical chain model to ...

For those of us who aren’t blessed with a green thumb and who are perhaps a bit forgetful, plants can be surprisingly ...
