Abstract
An electronic device () such as a cell phone, or a proximity detector for an electronic device (), has an ultrasound transmitter (), an ultrasound receiver (), and a processing system. It transmits an ultrasonic sine-wave signal from the transmitter (), and receives the ultrasonic sine-wave signal, through air, at the receiver (). It detects when the frequency of the transmitted signal and a frequency of the received signal satisfy a predetermined difference criterion, and uses this to determine whether to disable or enable a touch or touchless input () on the device ().
