Abstract
This disclosure describes, in part, techniques for using presence detection in order to switch between power modes of a device. The disclosure relates to detection of oscillating and rotating objects (or other repetitive motion objects) for rejection of radar returns related to the motion of such objects. Accordingly, the systems described herein provide for identifying radar returns as related to a repetitive motion object in proximity of the device. The radar returns can be processed to determine if related to a repetitive motion object such as a fan or a non-repetitive motion object such that the device can be controlled for presence detection based on actual presence and avoiding false presence detections due to repetitive motion and movement.
