Abstract
A hand-held device with a sensor for providing a signal indicative of a position of the hand-held device relative to an object surface enables 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, enables 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 enables 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.
