Abstract

A system for providing a configurable display for a signal activated device may include a receiver, a memory, a processor, and a display. The receiver may be operative to receive a radio frequency signal. The memory may be coupled with the receiver, and may be operative to store an item. The processor may be coupled with the memory and may be operative to retrieve the item stored in the memory, in response to the activation signal received by the receiver. The processor may use a current induced in the receiver by the radio frequency signal to retrieve the item. The display may be coupled with the processor and may be operative to display the item retrieved from memory using the current induced in the receiver.

Claims

1. A method of providing a configurable display for a signal activated device, comprising:

receiving a radio frequency signal through an antenna, the radio frequency signal inducing a current in the antenna;

retrieving an item stored in a memory coupled with the antenna, in response to the radio frequency signal, using the current induced in the antenna; and

displaying the item using the current induced in the antenna.

2. The method of claim 1 wherein displaying the item using the current induced in the antenna further comprises displaying the item, on a display coupled with the memory, using the current induced in the antenna.

3. The method of claim 2 wherein the display comprises a low power electronically controllable display.

4. The method of claim 2 wherein the display comprises a plurality of organic light-emitting diodes.

5. The method of claim 2 wherein the display comprises a plurality of organic thin film transistors.

6. The method of claim 1 further comprising displaying the item in a machine readable format.

7. The method of claim 6 wherein the machine readable format comprises a bar code.

8. The method of claim 1 further comprising displaying the item in a human readable format.

9. The method of claim 1 further comprising:

determining whether a security criterion has been satisfied; and

displaying the item using the current induced in the antenna if the security criterion has been satisfied, otherwise not displaying the item.

10. A method of displaying data stored in a radio frequency identification device, comprising:

receiving an activation signal by a receiver of a radio frequency identification device;

retrieving an item from a memory of the radio frequency identification device in response to the activation signal; and

displaying the item on a display of the radio frequency identification device.

11. The method of claim 10 wherein the activation signal comprises a radio frequency signal.

12. The method of claim 10 wherein the activation signal comprises at least one of an optical signal, a magnetic signal, or an infra-red signal.

13. The method of claim 10 wherein the activation signal comprises a laser from a bar code reader.

14. The method of claim 10 wherein the activation signal is received from a touch sensor.

15. The method of claim 10 wherein the activation signal is received from a timer.

16. The method of claim 10 wherein the display comprises a low power electronically controllable display.

17. The method of claim 10 further comprising:

determining whether a security criterion has been satisfied; and

displaying the item on the display of the radio frequency identification device if the security criterion has been satisfied, otherwise not displaying the item on the display of the radio frequency identification device.

18. A method of verifying memory rewrites in a signal activated device, comprising:

receiving a radio frequency signal through an antenna, the radio frequency signal comprising an update item;

storing the update item in a memory coupled to the antenna using a current induced in the antenna by the radio frequency signal; and

displaying the update item using the current induced in the antenna.

19. A system for providing a configurable display for a signal activated device, comprising:

a receiver operative to receive a radio frequency signal;

a memory, coupled with the receiver, operative to store an item;

a processor, coupled with the memory, operative to retrieve the item stored in the memory, in response to the radio frequency signal, using a current induced in the receiver by the radio frequency signal; and

a display, coupled with the processor, operative to display the item using the current induced in the receiver.

20. The system of claim 19 wherein the receiver comprises a radio frequency antenna.

21. The system of claim 19 wherein the display comprises a low power electronically controllable display.

22. The system of claim 19 wherein the display comprises a plurality of organic light-emitting diodes.

23. The system of claim 19 wherein the display comprises a plurality of organic thin film transistors.

24. The system of claim 19 wherein the display is operative to display the item in a machine readable format.

26. The system of claim 19 wherein the display is further operative to display the item in a human readable format.

27. The system of claim 20 wherein the processor is further operative to determine whether a security criterion has been satisfied.
