Abstract: This work presents a low power ultrasonic transceiver line array enabling energy efficient airborne object detection. The line array is based on capacitive micromachined ultrasonic ...

You take what you think is the perfect photo. Then you notice it. Someone in the background. A trash can. Power lines cutting across the frame. Normally, that photo is pretty much ruined. Not anymore.

Abstract: Many object recognition techniques rely on visual-based detection, requiring high-quality cameras and substantial computing power for high recognition accuracy. When visual detection ...
