Abstract

An apparatus for managing an energy consuming load in a group of energy consuming loads comprising the load and a plurality of other loads, including a transmitter to transmit a set of load state data generated from the load and a receiver to receive sets of load state data generated from the other loads. A processor generates the set of load state data from the load, to compile the set of load state data from the load with the sets of load state data from the other loads, and to process the compiled sets of load state data in order to make an enablement state decision for the load, wherein the enablement state decision reflects an enablement state of the load which is either a load enabled or a load disabled state. The enablement state decision is made independently of the other loads, and is implemented by a controller.

Claims

1. An apparatus for managing an energy consuming load in a group of energy consuming loads comprising the load and a plurality of other loads, the apparatus comprising:

(a) a transmitter configured to transmit a set of load state data generated from the load;

(b) a receiver configured to receive sets of load state data generated from the other loads;

(c) a processor configured to generate the set of load state data from the load, to compile the set of load state data from the load with the sets of load state data from the other loads, and to process the compiled sets of load state data in order to make an enablement state decision for the load, wherein the enablement state decision reflects an enablement state of the load, wherein the enablement state is either a load enabled state or a load disabled state, and wherein the enablement state decision of the load is made independently of the enablement state decisions of the other loads without negotiation amongst the load and the other loads and without regard to the enablement state decisions affecting the other loads; and

(d) a controller for implementing the enablement state decision.

2. The apparatus as claimed in claim 1 wherein the controller is comprised of a control circuit and a switch.

3. The apparatus as claimed in claim 2 wherein the load is connected within an energization circuit and wherein the switch is actuatable so that the energization circuit is closed when the load is in the load enabled state and so that the energization circuit is open when the load is in the load disabled state.

4. The apparatus as claimed in claim 3 wherein the load is comprised of an electrical load and wherein the energization circuit is comprised of an electrical energy source.

5. The apparatus as claimed in claim 2 wherein the load is connected within a control line circuit and wherein the switch is actuatable so that the control line circuit is closed when the load is in the load enabled state and so that the control line circuit is open when the load is in the load disabled state.

6. The apparatus as claimed in claim 5 wherein the control line circuit is comprised of an electrical control line.

7. The apparatus as claimed in claim 1 wherein the transmitter is comprised of a wireless transmitter and wherein the receiver is comprised of a wireless receiver.

8. The apparatus as claimed in claim 7 wherein the wireless transmitter is comprised of a radio frequency wireless transmitter and where the wireless receiver is comprised of a radio frequency wireless receiver.

9. The apparatus as claimed in claim 8 wherein the wireless transmitter and the wireless receiver are configured to comply substantially with an IEEE 802.15.4 standard.

10. The apparatus as claimed in claim 1 wherein the load has an energy demand and wherein the apparatus is further comprised of a sensor device for sensing the energy demand of the load.

11. The apparatus as claimed in claim 10 wherein the load is an electrical load and wherein the sensor device is comprised of an electrical energy sensor device.

12. The apparatus as claimed in claim 11, further comprising a rechargeable battery for providing electrical power to the apparatus and further comprising a recharge circuit for recharging the battery.

13. The apparatus as claimed in claim 12 wherein the recharge circuit is comprised of the electrical energy sensor device.

14. The apparatus as claimed in claim 1, further comprising a device for adjusting the duty cycle of the load.

15. The apparatus as claimed in claim 14, further comprising a display for providing a visual representation of the duty cycle of the load.
