Abstract

A remote control device is provided that is configured for use in a load control system that includes one or more electrical loads. The remote control device includes a mounting structure and a control unit, and the control unit is configured to be attached to the mounting structure in a plurality of different orientations. The control unit includes a user interface, an orientation sensing circuit, and a communication circuit. The control unit is configured to determine an orientation of the control unit via the orientation sensing circuit. The control unit is also configured to translate a user input from the user interface into control data to control an electrical load of the load control system based on the orientation of the control unit and/or provide a visual indication of an amount of power delivered to the electrical load based on the orientation of the control unit.

First claim

The invention claimed is:

1. A remote control device that is configured for use in a load control system, the remote control device comprising:
a mounting structure; and
a control unit configured to be attached to the mounting structure in a plurality of orientations, the control unit comprising a user interface, a communication circuit, and a switch configured to indicate an orientation of the control unit relative to the mounting structure;
wherein the control unit is configured to:
determine an orientation of the control unit relative to the mounting structure in response to a state of the switch;
translate a user input from the user interface into control data based on the orientation of the control unit, the control data configured to control an electrical load of the load control system; and
cause the communication circuit to transmit a control signal comprising the control data.

2. The remote control device of claim 1 , wherein the switch of the control unit is configured to be closed when the control unit is in a first orientation and open when the control unit is in a second orientation.

3. The remote control device of claim 2 , further comprising:
a faceplate that is configured to be attached to the mounting structure, the faceplate having an opening that is configured to receive at least a portion of the user interface;
wherein the switch comprises two electrical contact pads that are configured to be in electrical communication with a shorting member of the faceplate when the control unit is in the first orientation and not in electrical communication with the shorting member of the faceplate when the control unit is in the second orientation.

4. The remote control device of claim 3 , wherein the two electrical contact pads reside on a printed circuit board (PCB) of the control unit.

5. The remote control device of claim 2 , wherein the switch comprises two electrical contact pads that are configured to be in electrical communication with a shorting member of the mounting structure when the control unit is in the first orientation and not in electrical communication with the shorting member of the mounting structure when the control unit is in the second orientation.

6. The remote control device of claim 2 , wherein the mounting structure comprises a protrusion and the switch comprises a tactile switch on the control unit, and wherein the protrusion is configured to actuate the tactile switch when the control unit is attached to the mounting structure in the first orientation, but not actuate the tactile switch when the control unit is attached to the mounting structure in the second orientation.

7. The remote control device of claim 2 , wherein the switch comprises a gravity switch that is configured to be in the closed position when the control unit is in the first orientation and the open position when the control unit is in the second orientation.

8. The remote control device of claim 2 , wherein the switch comprises a mercury switch that is configured to be in the closed position when the control unit is in the first orientation and the open position when the control unit is in the second orientation.

9. The remote control device of claim 1 , wherein the switch is configured to be manually operated to indicate the orientation of the control unit.

10. The remote control device of claim 1 , wherein the control unit is configured to automatically determine the orientation of the control unit upon the control unit being attached to the mounting structure.

11. The remote control device of claim 1 , wherein the control unit is configured to determine the orientation of the control unit each time the control unit wakes up from an off or sleep state.

12. A remote control device that is configured for use in a load control system, the remote control device comprising:
a mounting structure; and
a control unit configured to be attached to the mounting structure in a plurality of orientations, the control unit comprising a user interface comprising a plurality of light sources, a communication circuit, and a switch configured to indicate an orientation of the control unit relative to the mounting structure;
wherein the control unit is configured to:
determine an orientation of the control unit relative to the mounting structure in response to a state of the switch; and
control the plurality of light sources to provide a visual indication based on the orientation of the control unit.

13. The remote control device of claim 12 , wherein the switch of the control unit is configured to be closed when the control unit is in a first orientation and open when the control unit is in a second orientation.

14. The remote control device of claim 13 , further comprising:
a faceplate that is configured to be attached to the mounting structure, the faceplate having an opening that is configured to receive at least a portion of the user interface;
wherein the switch comprises two electrical contact pads that are configured to be in electrical communication with a shorting member of the faceplate when the control unit is in the first orientation and not in electrical communication with the shorting member of the faceplate when the control unit is in the second orientation.

15. The remote control device of claim 14 , wherein the two electrical contact pads reside on a printed circuit board (PCB) of the control unit.

16. The remote control device of claim 13 , wherein the switch comprises two electrical contact pads that are configured to be in electrical communication with a shorting member of the mounting structure when the control unit is in the first orientation and not in electrical communication with the shorting member of the mounting structure when the control unit is in the second orientation.

17. The remote control device of claim 13 , wherein the mounting structure comprises a protrusion and the switch comprises a tactile switch on the control unit, and wherein the protrusion is configured to actuate the tactile switch when the control unit is attached to the mounting structure in the first orientation, but not actuate the tactile switch when the control unit is attached to the mounting structure in the second orientation.

18. The remote control device of claim 13 , wherein the switch comprises a gravity switch that is configured to be in the closed position when the control unit is in the first orientation and the open position when the control unit is in the second orientation.

19. The remote control device of claim 13 , wherein the switch comprises a mercury switch that is configured to be in the closed position when the control unit is in the first orientation and the open position when the control unit is in the second orientation.

20. The remote control device of claim 12 , wherein the switch is configured to be manually operated to indicate the orientation of the control unit.

21. The remote control device of claim 12 , wherein the control unit is configured to automatically determine the orientation of the control unit upon the control unit being attached to the mounting structure.

22. The remote control device of claim 12 , wherein the control unit is configured to determine the orientation of the control unit each time the control unit wakes up from an off or sleep state.
