20120127124 | Dual Mode Touchpad with a Low Power Mode Using a Proximity Detection Mode - A system includes a touchpad sensor array, a touch circuit, and a proximity circuit. The touch circuit executes a touch mode configured to track the position of a user or conductive object on the touchpad sensor array by detecting a change in an electrical property of the touchpad. The proximity circuit executes a proximity detection mode configured to track the position of a user or conductive object near or proximate to the touchpad sensor array by detecting a change in an electrical property of the touchpad. The system is configured to switch from the touch mode to the proximity detection mode after a predetermined period of inactivity, where the proximity detection mode can operate at one or more reduced polling rates, resulting in a reduced overall power dissipation. The system is configured to switch back to the touch mode when activity is detected by the proximity circuit. | 05-24-2012 |
