Abstract
An ultrasonic input includes two or more ultrasonic transceiver units having transducers separated from each other by a predetermined spacing and a processor coupled to the transceiver units. In some implementations one unit transmits while two receive and in other implementations one unit transmits and receives while the other just receives. The transmitter sends an ultrasonic pulse and first and second receivers receive echoes of the ultrasonic pulse from an object. The processor and/or transceiver units use first and second receive signals to determine first and second time-of-flight (ToF) measurements corresponding to times between transmitting an ultrasonic pulse and receiving an echo of the ultrasonic pulse.
