Abstract

A utility conservation system and method uses a system controller to detect an access device entering or leaving a building area. A wireless transmission corresponding to the detection is received by one or more interruption devices that connect or remove an electrical load from an electrical supply for conservation when the building area is unoccupied.

Claims

1. A conservation system for a building area requiring an access device to gain entry, comprising in combination:

a system control device comprising a sensor for detecting said access device and further comprising a transmitter coupled to said sensor for wirelessly transmitting a result of said detecting; and

an interruption device for interrupting use of a resource managed by said conservation system, comprising a receiver for wirelessly receiving said result of said detecting and further comprising a switch coupled to said receiver, said switch being electrically coupled between an electrical supply and an electrical load, wherein said switch operates in conformity with said result of said detecting to control use of said resource.

2. The system of claim 1 wherein said resource comprises power supplied to an air-conditioner.

3. The system of claim 2 wherein said interruption device further comprises a timer coupled to said receiver and further coupled to said switch, so that an operation of said switch is controlled by said timer when said access device is not detected.

4. The system of claim 3 wherein said interruption device further comprising a duty-cycle control for controlling the duty-cycle of said operation of said switch when said access device is not detected.

5. The system of claim 1 wherein said interruption device further comprising a wall-mounted electrical receptacle for controlling an operation of an appliance coupled to said wall-mounted electrical receptacle, whereby said resource comprises power supplied through said wall-mounted electrical receptacle.

6. The system of claim 1 wherein said resource is water and wherein said electrical load comprising an electrically-controlled valve in a water supply line for controlling a water flow when said access device is not detected.

7. The system of claim 1 wherein said electrical load comprising a motor coupled to a window blind for controlling an operation of said window blind when said access device is not detected.

8. The system of claim 1 further comprising a manual switch coupled between said electrical supply and said electrical load.

9. The system of claim 1 wherein said access device is a key card having a magnetic stripe, wherein said system control device further comprising a holder for holding said key card, and wherein said sensor detects said magnetic stripe when said access device is positioned in said holder.

10. The system of claim 1, wherein said access device is a key card having an opaque portion, wherein said sensor detects light, and wherein said system control device further comprising a light source and a holder for holding said key card between said sensor and said light source, whereby said system control device detects said opaque portion of said key card between said light source and said sensor.

11. A resource conservation system for a building area requiring a key card to gain entry, comprising in combination:

conservation data encoded on said key card;

a system control device located inside said building area and proximate an entryway to said building area, said system control device comprising a key card holder, a sensor for detecting said conservation data, and a transmitter coupled to said sensor for wirelessly transmitting a result of said detecting; and

a first interruption device for interrupting use of a first resource managed by said conservation system, comprising a receiver for wirelessly receiving said result of said detecting and a switch coupled to said receiver, said switch being electrically coupled between an electrical supply and a first electrical load, wherein said switch operates in conformity with said result of said detecting to control use of said first resource.

12. The system of claim 11, wherein said first resource is power and wherein said first electrical load comprises at least one of an air conditioner, a wall-mounted electrical receptacle, an electrically-controlled valve in a water supply line, a motor coupled to a window blind, and a manual switch.

13. The system of claim 12 wherein said first interruption device further comprises:

a timer; and

a duty-cycle control coupled to said timer and further coupled to said switch for controlling said operation of said switch in conformity with said detecting.

14. The system of claim 11, further comprising a second interruption device for interrupting use of a second resource managed by said conservation system, comprising a receiver for wirelessly receiving said result of said detecting and a switch coupled to said receiver, said switch being electrically coupled between an electrical supply and at least one of an air conditioner, a wall-mounted electrical receptacle, an electrically-controlled valve in a water supply line, a motor coupled to a window blind, and a manual switch, wherein said switch operates in conformity with said result of said detecting to control use of said second resource.

15. The system of claim 11 wherein said sensor comprises at least one of a magnetic stripe detector and a photodetector.

16. The system of claim 11, further comprising a second interruption device for interrupting use of a resource managed by said conservation system, comprising a receiver for wirelessly receiving said result of said detecting and a switch coupled to said receiver, said switch being electrically coupled between an electrical supply and a first electrical load, and wherein said conservation information comprises first information controlling an operation of said first interruption device when said key card is removed from said key card holder and further comprises second information controlling an operation of said second interruption device when said key card is removed from said key card holder.

17. A resource conservation method for a building area requiring an access device to gain entry, comprising the steps of:

wirelessly transmitting a first signal in response to said access device proximate said building area;

electrically coupling an electrical load to an electrical supply in response to said first signal;

wirelessly transmitting a second signal in response to said access device leaving said building area; and

electrically decoupling said electrical load from said electrical supply in response to said second signal.

18. The method of claim 17 wherein said wirelessly transmitting said first signal is performed by an access device holder detecting an insertion of said access device, and wherein said wirelessly transmitting said second signal is performed by said access device holder detecting a removal of said access device.

19. The method of claim 17 wherein said electrically coupling is performed by an interruption device comprising a receiver and a switch coupled to said receiver, said switch being electrically coupled between said electrical supply and said electrical load.

20. The method of claim 17 wherein said resource comprises power supplied to an air-conditioner.
