Abstract

A system and method for managing the power consumption of power-consuming devices. A remote device manager transmits power save schedules to a local device manager over a communication network such as the internet. The local device manager transmits power save commands to one or more devices in a location such as a store, over a dedicated local communication network. The commands instruct one or more devices to activate or de-activate its power save mode according to the power save schedules. The commands could be dependent upon one or more trigger events.

Claims

1. A system for managing power consumption of at least one device, the system comprising:

a first device manager for transmitting at least one power save schedule; and

a second device manager for receiving the at least one power save schedule, the second device manager also in communication with the one or more devices, the second device manager configured to transmit power save commands based on the at least one power save schedule to the one or more devices and to receive power mode status signals from the one or more devices;

the at least one power save schedule defining power mode activation and deactivation times for the one or more devices, activation and deactivation taking place upon occurrence of a trigger event.

2. The system of claim 1, wherein the at least one device is an electronic article surveillance device and is grouped and scheduled according to a location within a corresponding electronic article surveillance interrogation area.

3. The system of claim 1, wherein the at least one device is grouped and scheduled according to a similarity in function with other devices.

4. The system of claim 1, wherein the at least one device is an electronic article surveillance device and the second device manager is located within an electronic article surveillance interrogation area.

5. The system of claim 1, wherein the trigger event is a specific time on a specific day of the week.

6. The system of claim 1, wherein the at least one device is a product deactivation device and the trigger event is a point-of-sale transaction involving the deactivation device.

7. The system of claim 1 wherein the at least one device is a people detection device and the trigger event is based upon a number of people passing within a predetermined proximity of the people detection device.

8. The system of claim 1, wherein the at least one power save schedule can be altered by the first device manager.

9. The system of claim 8, wherein the second device manager transmits the received power mode status signals from each device to the first device manager, and wherein the first device manager alters at least one power save schedule based on the received power mode signals.

10. The system of claim 1, wherein the at least one power save schedule can be altered by the second device manager.

11. The system of claim 1, wherein the second device manager creates a profile for each of the one or more devices and alters the at least one power schedule based on the profile for each device.

12. A power management system for managing power consumption of at least one device, the power management system comprising:

a local device manager in communication with the at least one device; and

a remote device manager in communication with the local device manager, the remote device manager comprising;

a scheduling module for creating at least one power save schedule; and

a schedule communication module for sending the at least one power save schedule to the local device manager,

the local device manager transmitting power save commands based on the at least one power save schedule to the at least one device; and

receiving power mode status signals from the one or more devices;

the schedule communication module receiving the power mode status signals from the local device manager, the scheduling module altering the at least one power save schedule based on the received power mode signals.

13. The power management system of claim 12, wherein the local device manager creates a profile for each device and communicates the profile to the remote device manager, the remote device manager storing and managing the profiles received from the local device manager.

14. A method for managing power consumption of at least one device, the method comprising:

creating, at a remote device manager, at least one power save schedule, the at least one power save schedule dictating when each of the at least one device enters into a power save mode;

receiving, at a local device manager, power status information from each of the at least one device, the local device manager in communication with the remote device manager;

updating the at least one power save schedule based upon the received power status information; and

transmitting power mode commands to the at least one device, the power mode commands based upon the at least one power save schedule and the power status information and instructing the at least one device to either activate or deactivate their power save mode.

15. The method of claim 14, wherein the power mode commands instruct the at least one device to activate or deactivate their power save mode based upon the occurrence of a trigger event.

16. The method of claim 15, wherein the trigger event is a specific time on a specific day of the week.

17. The method of claim 15, wherein the at least one device is a product deactivation device and the trigger event is a point-of-sale transaction involving the deactivation device.

18. The method of claim 15 wherein the at least one device is a people detection device and the trigger event is based upon a number of people passing within a predetermined proximity of the detection device.

19. The method of claim 15, wherein the at least one device is an electronic article surveillance device and further comprising grouping and scheduling the at least one device according to a location within a corresponding electronic article surveillance interrogation area.

20. The method of claim 15, further comprising grouping and scheduling the at least one device according to a similarity in function with other devices.
