Abstract
Multiple independently movable devices are located upon a platform. On the platform is a directional microphone array. Each of the movable devices is assigned a unique audio signature, which may be a pulse train of chirps or a pseudo random signal or some other audio sequence that is unique to the respective device. Each movable device announces itself with its unique audio signature, and the platform's directional microphone system determines the location from which the unique audio signature comes from. For range, a difference between the time of flight (TOF) of the light relative to the sound signature is used. As another technique a unique audio signature may be an audio water mark concealed in normal audio which may be emitted by the movable device. The watermark provides the identifying information of each movable device.
