Tap-to-wake and tap-to-login near field communication (NFC) device

摘要

Described herein are techniques related to a tap-to-wake and tap-to-login system. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope and meaning of the claims. A tap-to-wake and tap-to-login system allows a user of a near field device to wake up a computing platform from a deep sleep state using a bump/tap without having to move a mouse or enter a keyboard stroke.

主权项

1. An apparatus comprising:
a wireless communication module that is configured to detect a presence of a wireless communication device while the wireless communication module is in a device-detect mode and at a power-gated sleep state; an authentication module that is configured to obtain an indication of the detection of the presence of the wireless communication device from the wireless communication module and, in response to the obtained indication, to authenticate the wireless communication device; a login module that is configured to obtain a login credential for the wireless communication device and to validate the login credential; and a power management module that is configured to cause a power state of a computing device platform to change from the device-detect mode to a first power state in response to the validation of the login credential and the indication of the detection of the presence of the wireless communication device from the wireless communication module, and to change from the first power state to a second power state in response to the indication from the authentication module that the wireless communication device is authenticated, wherein the first power state and the second power state includes a low-power state and a normal operation power state, respectively, of the apparatus.
