Abstract: A novel extrinsic Fabry–Perot interferometric (EFPI) ultrasonic sensor is developed that can detect ultrasonic signals of partial discharge (PD) in high-voltage electrical equipment under ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: In the emerging field of mobile robotics, Simultaneous Localization and Mapping (SLAM) of robots play an increasingly important role. In spite of the availability of various algorithms and ...
