US Patent 11853497 Power management for input device

An input device for a computer system includes a force sensor, disposed in a dedicated sensing region, a touch sensor, disposed in the dedicated sensing region, and a processing system. The processing system detects a presence of a force applied in the dedicated sensing region, using the force sensor, and based on the detection of the presence of the force, changes a state of the input device from an idle state to an active state. When in the idle state, touch sensing by the input device is inactive. When in the active state, the touch sensing by the input device is active.
