Abstract: The present disclosure is directed to routine recognition for adjusting the power state of a device. Human activity recognition is performed to detect various activity states, and create a current sequence of activity states. In response to detecting a new activity state, routine comparison is performed in order to compare the current sequence to a past sequence that ended with the user starting to interact with the device. The device is preemptively turned on in response to finding a match.

Abstract: The present disclosure is directed to human presence detection with an infrared sensor. The human presence detection utilizes signal regularization and edge detection to minimize the effect of drift on the human presence detection. The human presence detection is accurate regardless of changes in ambient temperatures.
