Multimode device for locating and identifying items

1. An integrated identification system comprising:

a housing;

an active light beacon supported by the housing;

an RF beacon, including an RF receiver, supported by the housing; and

a controller coupled to the active light beacon and RF beacon to facilitate independent control of the active light beacon and RF beacon responsive to receipt of an RF command by the RE receiver.

2. The integrated identification system of claim 1 and further comprising an IR reflector supported by the housing.

3. The integrated identification system of claim 1 and further comprising an IR reflector disposed on an outside surface of the housing.

4. The integrated identification system of claim 1 wherein the RF beacon includes a battery and varies a duty cycle to conserve battery life.

5. The integrated identification system of claim 1 wherein the RF beacon transmits a coded RE signal.

6. The integrated identification system of claim 5 wherein coded RF signal is coded to uniquely identify an item or person.

7. The integrated identification system of claim 1 wherein the active light beacon emits an IR pulse of light that is coded.

8. The identification system of example 1 and further comprising a controller to receive external commands.

9. The identification system of claim 8 wherein the controller is adapted to turn on either or both beacons responsive to the commands.

10. The identification system of claim 8 and further comprising a battery to power the controller and the beacons and wherein the controller controls the activated beacon or beacons to periodically transmit identification signals and lengthens a period between transmissions based on remaining battery life.

11. An identification system comprising:

a housing;

a passive IR reflector positioned on at least one outside surface of the housing;

an active light beacon supported by the housing;

an RF beacon supported by the housing;

a controller coupled to control the active light beacon and the RF beacon;

an RF receiver coupled to receive transmitted commands and provide the commands to the controller; and

wherein the controller is configured to independently activate the active light beacon and RF beacon responsive to the commands.

12. The identification system of example 11 and further comprising a memory device coupled to the controller and having controller executable instructions to cause the controller to activate the active light beacon and RF beacon responsive to the commands.

13. The identification system of example 12 and further comprising a battery coupled to power the beacons, wherein the RF beacon varies a duty cycle to conserve battery life.

14. The identification system of example 12 wherein the RE beacon transmits a coded RE signal.

15. The identification system of example 14 wherein the coded RE signal is coded to uniquely identify an item or person.

16. The identification system of example 12 wherein the active light beacon emits an IR pulse of light that is coded.

17. The identification system of example 12 wherein the controller is configured to turn on either or both beacons responsive to the commands.

18. The identification system of example 12 and further comprising a battery to power the controller and the beacons and wherein the controller controls the activated beacon or beacons to periodically transmit identification signals and lengthens a period between transmissions based on remaining battery life.

19. A method comprising:

receiving a command via an RE receiver to turn on a beacon;

determining which beacon to turn on from an RE beacon and an active light beacon integrated into an identification device;

turning on the determined beacon; and

periodically transmitting a coded pulse identifying a person wearing the identification device.

20. The method of claim 19 and further comprising reflecting IR signals impinging on the identification device via an IR reflector disposed on an outside surface of the identification device.
