Abstract: Techniques for proximity-sensing devices to detect movement of a person in an environment by emitting pulsed ultrasonic signals into the environment, and detecting a change in the energy measurements of the reflections of the pulsed ultrasonic signals off the person caused by the movement of the person relative to the proximity-sensing devices. In addition to detecting movement, and thus presence, of a person, the proximity-sensing devices may further perform techniques for identifying a direction of movement of the person, and also to perform techniques for identifying a number of people that are in the room. The use of pulsed ultrasonic signals, and monitoring changes in energy in reflections of the emitted signals over time, not only enables movement detection and tracking, but also requires less power and computing resources than continuous emission techniques.
