Abstract
An apparatus having a touch sensor able to detect the touch of a tip of a digit of a user, having a conductive ring able to detect the approach of the tip towards the touch sensor, having a motion sensor to sense movement of a casing the apparatus, and having components of a controller to place the apparatus in one of a lower power mode after a predetermined period of inactivity has elapsed, a partial power mode in response to an indication of the approach of a tip of a digit, and a higher power state to detect touching of the touch sensor by a tip of a digit. Other forms of proximity detectors may be employed in place of the conductive ring, or the conductive ring may be replaced by one or more elongate conductors positioned about one or more sides of the periphery of a touch-sensitive surface of the touch sensor.
