DEVICE THAT MANAGES POWER PROVIDED TO AN OBJECT SENSOR
First Claim
1. A non-transitory, computer readable media having stored thereon instructions for managing a hand-held device having a touch sensitive surface providing at least one input element, a plurality of hard keys, and a sensor, the instructions, when executed by a processing unit of the hand-held device, performing steps comprising:
- using signals received from the sensor to determine when the hand-held portable device has been moved proximate to an object surface and to determine when the hand-held portable device has been subsequently moved away from the object surface; and
causing the hand-held device to transition from a first operational mode to a second operational mode when it is determined from a signal received from the sensor that the hand-held portable device has been moved proximate to the object surface and to transition from the second operational mode back to the first operational mode when it is determined from a signal received from the sensor that the hand-held portable device has been subsequently moved away from the object surface;
wherein, in the first operational mode, the instructions cause the touch sensitive surface and the plurality of hard keys to be monitored for user input and, in the second operational mode, the instruction cause only the plurality of hard keys to be monitored for user input with the touch sensitive user interface being disabled.

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.
