Abstract

The present invention provides radio frequency identification devices, remote communication devices, identification systems, communication methods, and identification methods. A radio frequency identification device according to one aspect includes a substrate; communication circuitry coupled with the substrate and configured to receive a wireless signal including an identifier, to process the identifier of the wireless signal and to output a control signal responsive to the processing of the identifier; and indication circuitry coupled with the communication circuitry and configured to receive the control signal and to indicate presence of the radio frequency identification device responsive to the control signal. A communication method according to another aspect includes providing a radio frequency identification device; receiving a wireless signal including an identifier within the radio frequency identification device; processing the identifier; generating a control signal after the processing; and indicating presence of the radio frequency identification device using indication circuitry of the radio frequency identification device responsive to the control signal.

Claims

1-5. -5. (canceled)

6. A radio frequency device configured to provide an indication relating to the location of an object disposed at a first location, the radio frequency device comprising:

apparatus configured to receive from a radio frequency communications device a first radio frequency signal;

apparatus configured to transmit a second radio frequency signal in response to receipt of the first radio frequency signal; and

apparatus configured to provide an indication associated with the first location, said indication being representative of the proximity of the radio frequency device to the radio frequency communications device.

7. The radio frequency device of claim 6, wherein the indication includes a visual indication of the first location.

8. The radio frequency device of claim 7, wherein the visual indication includes a light.

9. The radio frequency device of claim 6, wherein the indication is further configured to indicate generation of wireless signals from said radio frequency communications device.

10. The radio frequency device of claim 6, wherein the indication includes an audible indication.

11. The radio frequency device of claim 6, wherein the apparatus configured to provide an indication is further configured to assist with the determination of the communication range of the radio frequency communications device.

12. The radio frequency device of claim 6, wherein the apparatus configured to provide an indication is further configured to indicate operation of the radio frequency device.

13. The radio frequency device of claim 6, wherein the first radio frequency signal comprises at least a portion of an identifier associated with the radio frequency device.

14. A radio frequency device configured to provide an indication relating to the location of an object disposed at a first location, the radio frequency device comprising:

a receiver configured to receive a first message that includes at least a portion of an identifier of the radio frequency device;

a transmitter configured to transmit, to the transmitting radio frequency device, a second message comprising the identifier; and

an indicator that when invoked is representative of the proximity of the radio frequency device to the transmitting radio frequency device.

15. The radio frequency device of claim 14, wherein the indicator provides a visual indication relating to the first location.

16. The radio frequency device of claim 15, wherein the visual indication includes a light.

17. The radio frequency device of claim 14, wherein said indicator is further configured to indicate generation of wireless signals from the transmitting radio frequency device.

18. The transmitting radio frequency device of claim 14, wherein the indicator is further configured to include an audible indication.

19. A radio frequency device configured to provide an indication relating to the location of an object disposed at a first location, the radio frequency device comprising:

a receiver configured to receive a first message, the first message being indicative of at least a transmitting radio frequency device; and

an indication apparatus configured to provide an indication that is indicative of the proximity of the transmitting radio frequency device to the first location.

20. The radio frequency device of claim 19, wherein the indication apparatus further includes a visual indication at the first location.

21. The radio frequency device of claim 20, wherein the visual indication includes a light.

22. The radio frequency device of claim 19, wherein the indication apparatus is further configured to indicate generation of wireless signals from said transmitting radio frequency identification device.

23. The radio frequency device of claim 19, wherein the indication apparatus is further configured to facilitate the rapid identification of the item at the first location.

24. The radio frequency device of claim 23, wherein the indication apparatus is further configured to allow for distinguishing the item from other items.
