Abstract

A configurable remote controller for remotely sensing the status(es) of one or more electrically-powered target systems and for altering the status(es) of the target systems in response. In one embodiment, the remote control device is coupled to a preexisting communication channel established between a command system and one or more target systems. A system administrator transmits control instructions over the pre-existing communication channel to the remote controller. The remote controller receives and processes the control instructions as well as senses for a change in the status of at least one of the target systems. If a change in status is detected, then the remote controller alters the status in accordance with the control instructions. The change can be a lowering of the voltage level in which disconnecting the one target system from the power source can be considered a form of altering the status.

Claims

1. A method for remotely controlling a plurality of systems, said method comprising:

receiving control instructions passing through a pre-existing communication channel of the plurality of systems;

processing said control instructions by a remote controller;

directly sensing a first change in a status of a first system of said plurality of systems, said sensing being separate from said receiving and said processing, said status directly relating to the control instructions; and

upon sensing said first change, altering the status of said first system by transferring a message to a selected system of the plurality of system, the message being in accordance with said control instructions for dissemination to the first system of the plurality of systems.

2. The method of claim 1 wherein said status is a voltage level of a primary power source associated with said first system, said first change is a lowering of said voltage level normally associated with a power outage or a brown-out of said primary power source.

3. The method of claim 1 further comprising:

directly sensing a second change in the status of said first system; and

upon sensing said second change, re-altering the status of said first system in accordance with said control instructions.

4. The method of claim 3 wherein said status is a voltage level of a primary power source associated with said first system, said first change is a lowering of said voltage level normally associated with a power outage or a brown-out of said primary power source.

5. The method of claim 4 wherein said primary power supply is also coupled to a second system of said plurality of systems, and said altering and re-altering acts also decouple and recouple said power supply to and from said second system, respectively.

6. The method of claim 1 further comprising reprogramming said remote controller.

7. The method of claim 6 wherein said reprogramming includes:

transmitting additional control instructions through the pre-existing communicate channel; and

receiving and processing said additional control instructions by said remote controller.

14. The method of claim 1, wherein altering of the status of the first system includes decoupling the first system from the power source.

15. The method of claim 3 wherein said status is a voltage level of a primary power source associated with said first system, said first change is a lowering of said voltage level normally associated with a power outage or a brown-out of said primary power source, said altering includes decoupling said first system from said power source, and wherein said second change is a rise of said voltage level normally associated with a return of power to said primary power source.

16. The method of claim 15 wherein said status is a voltage level of a primary power source associated with said first system, said first change is a lowering of said voltage level normally associated with a power outage or a brown-out of said primary power source, and said altering step includes the step of decoupling said first system from said power source, and wherein said second change is a rise of said voltage level normally associated with a return of power to said primary power source, said re-altering includes recoupling said first system to said power source.

18. The method of claim 1, wherein the first system is the selected system.

19. The method of claim 1, wherein the first system is different than the selected system.

8. Adapted to a plurality of systems, a remote controller comprising:

a communication interface circuit configured to receive control instructions through a pre-existing communication channel;

a processor coupled to the communication interface circuit, said processor being configured to process said control instructions;

a first sensor physically separate from said communication interface circuit and said processor and coupled to said processor, the first sensor being adapted to a first system of the plurality of systems and configured to directly sense a change in a status of any of said plurality of systems, said status directly relating to the control instructions; and

a first controller coupled to said processor and adapted to the first system, the first controller being configured to alter said status of the first system in accordance said control instructions.

9. The remote controller of claim 8 wherein said status is a voltage level of a primary power source associated with said first system, said change is a lowering of said voltage level normally associated with a power outage or a brown-out of said primary power source, and said first controller is a switch for coupling/decoupling said first system to/from said power source.

10. The remote controller of claim 8 further comprising:

a second sensor configured to directly sense a change in a status of a second system of said plurality of systems; and

a second controller configured to alter the status of said second system in accordance with said control instructions.

11. The remote controller of claim 10 wherein said status is respective voltage levels of primary power sources associated with said first and second systems, said change is a lowering of said voltage levels normally associated with a power outage or a brown-out of said primary power sources, and said first and second controllers are switches for coupling/decoupling said first and second systems to/from said power sources.

12. The remote controller of claim 8 further comprising a reprogrammable memory configured to store said control instructions.

13. Adapted to control a plurality of systems, a remote controller comprising:

a tap connector attached to a pre-existing communication channel to allow a control instruction to be routed to both a first system of the plurality of systems and a communication interface circuit;

a processor coupled to the communication interface circuit to receive the control instruction, the processor being configured to process the control instruction;

a first sensor physically separate from said communication interface circuit and said processor, and coupled to said processor and adapted to the first system, said first sensor being configured to directly sense a change in a status of the first system, said status directly relating to the control instructions; and

a first controller coupled to said processor and adapted to the first system, the first controller being configured to alter the status of the first system in accordance said control instructions.

17. Adapted to a plurality of systems, a remote controller comprising:

a communication interface circuit configured to receive control instructions through a pre-existing communication channel;

a processor coupled to the communication interface circuit, the processor configured to process the control instructions;

a plurality of sensors separate from the communication interface circuit and the processor and coupled to the processor and to a selected system of the plurality of systems, each of the plurality of sensors further configured to directly sense a change in a status of the selected system, said status directly relating to the control instructions; and
