Abstract:
1. A hand-held device, comprising: a display having a touch sensitive, user input interface; a processing device in communication with the display; a sensor for providing to the processing device a signal indicative of a position of the hand-held device relative to an object surface; and a memory having instructions executable by the processing device for managing power provided by a battery to at least the sensor; wherein the instructions enable power to the sensor at a first time interval when the hand-held device is indicated to be in a position that is stationary and adjacent relative to the object surface, enable power to the sensor at a second time interval shorter than the first time interval when the hand-held device is indicated to be in a position that is moving and adjacent relative to the object surface, and enable power to the sensor at a third time interval when the hand-held device is determined to be in a position that is removed relative to the object surface.
