Abstract
Ultrasonic ranging for mobile devices is disclosed. A mobile device using ultrasonic ranging can include an ultrasound transmitter capable of emitting an ultrasound signal for detection by a proximate device and an ultrasound receiver capable of receiving an ultrasound signal from the proximate device. The mobile device can then use a time lapse associated with one or both of these ultrasound signals to find a range to the proximate device.
