LOW POWER SCAN FOR DEVICE WAKE UP AND UNLOCK

摘要

A low power can for device wake up and unlock is disclosed. The low power scan can include one or more algorithms used to detect a sequence and/or one or more gestures to wake up a processor and unlock the device for user interaction. A sequence and/or one or more gestures can be determined by a microcontroller and/or by a separate hardware component. The microcontroller can send a notification or a wake signal to the processor and/or switch the device from an idle to an active state. By detecting a sequence and one or more gestures in the microcontroller before powering on or waking up the processor, the amount of power consumed can be reduced and the battery life extended.

主权项

1. A method for switching a device from an idle state to an active state, the method comprising:
determining if a touch on a touch surface of the device is at least one of an object presence, tap, hold and swipe; and when the touch is at least one of the object presence, tap, hold and swipe, generating a wake notification.
