PORTABLE COMPUTER SLEEP MODE SYSTEM SENSORS

摘要

A sleep mode system for an electronic device can include a light source, a sensor, and a light altering component. The light altering component can rotate with one device component, such as a laptop lid, while the light source and/or sensor remain stationary with another device component, such as a laptop base. A controller can determine the orientation angle of the light altering component based on the detected light, and can put the device into or remove the device from a sleep mode based on the angle, which can reflect an open state or closed state for the electronic device.

主权项

1. An angular detection system configured for use in an electronic device, the angular detection system comprising:
a light source component; a light sensing component configured to detect light emitted from the light source component; and a light altering component configured to affect light emitted from the light source component before the light reaches the light sensing component based upon a variable rotation of the light altering component, wherein the variable rotation of the light altering component corresponds to a variable rotation of a first electronic device component with respect to a second electronic device component.
