An Ultrasonic 3D Positioning System Using a Single Compact Receiver Unit
We present a system that can identify positions of objects in three-dimensional space using ultrasonic communications. The proposed system uses the time of flight of ultrasonic waves to calculate the distance ...

A Scalable Ultrasonic-Based Localization System Using the Phase Accordance Method
We introduce a localization system using ultrasonic signals. Our system adopts the Phase Accordance Method, which we proposed previously for accurate distance measurement [1, 2]. Unlike other ultrasonic-based ...
