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.

First claim

What is claimed is:

1. A hand-held device, comprising:
a processing device;
a sensor coupled to the processing device;
a plurality of input receiving elements coupled to the processing device;
a first transmission device coupled to the processing device;
a second transmission device coupled to the processing device; and
a memory coupled to the processing device, the memory having stored thereon instructions wherein, when executed by the processing device, cause the hand-held device, to perform steps comprising: using signals received from the sensor to determine when the hand-held portable device is positioned proximate to an object surface and to determine when the hand-held portable device is removed from the object surface; and causing the hand-held device to automatically 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 automatically 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 hand-held device is configured to use the first transmission device when transmitting one or more communications in response to an activation of one or more of the plurality of input receiving elements and, in the second operational mode, the hand-held device is configured to use the second transmission device when transmitting one or more communications in response to an activation of one or more of the plurality of input receiving elements and wherein the first transmission device is different from the second transmission device.

2. The hand-held device as recited in claim 1 , wherein the first transmission device comprises a radio frequency transmission device and wherein the second transmission device comprises an infrared transmission device.

3. The hand-held device as recited in claim 1 , wherein, in the first operational mode, the hand-held device is configured to use a first command code set when transmitting one or more communications in response to an activation of one or more of the plurality of input receiving elements and, in the second operational mode, the hand-held device is configured to use a second command code set when transmitting one or more communications in response to an activation of one or more of the plurality of input receiving elements and wherein the first command code set is different than the second command code set.

4. The hand-held device as recited in claim 3 , wherein the first transmission device comprises a radio frequency transmission device and wherein the second transmission device comprises an infrared transmission device.

5. The hand-held device as recited in claim 3 , further comprising a touch sensitive display and wherein the plurality of input receiving elements comprise a plurality of soft input elements caused to be displayed in the touch sensitive display.

6. The hand-held device as recited in claim 5 , wherein, in the first operational mode, the hand-held device is configured to display a first set of the plurality of soft input elements in the touch sensitive display and, in the second operational mode, the hand-held device is configured to display a second set of the plurality of soft input elements in the touch sensitive display and wherein the first set of the plurality of soft input elements is different than the second set of the plurality of input elements.

7. The hand-held device as recited in claim 3 , wherein the instructions cause the hand-held device to use input received into the hand-held device to select the first command code set and the second command code set from a library of command code sets stored in the memory.

8. The hand-held device as recited in claim 7 , wherein the input used to select the first command code set and the second command code set is received via activations of one or more of the plurality of input receiving elements.

9. The hand-held device as recited in claim 3 , wherein the first command code set and the second command code set are received into the hand-held device from a device located remotely from the hand-held device.

10. The hand-held device as recited in claim 1 , wherein the instructions cause the hand-held device to use a distance between the hand-held device and the object surface as sensed by the sensor to determine when the hand-held device has been moved proximate to and away from the object surface.

11. The hand-held device as recited in claim 1 , wherein the sensor comprises an optical sensing system.
