Abstract

A bistable addressable label which is usable with a recordable media to display certain characteristics of the recordable media, including the remaining storage space available. An electric paper label according to this invention is usable with recordable media to display certain characteristics of the recordable media or data stored therein; for example, detecting a write/read function, activating the label display, retrieving format and access authorization to contain fields within the label display, retrieving a serialization number and updating the serialization number, evaluating content transfer, evaluating remaining storage space, date stamping content transfers, evaluating content media and transfer reporting error determinations and displaying location of errors.

Claims

1. An addressable display useable as a label, comprising:

a bistable display device usable as a label;

an energy source that generates an operating signal; and

a microcontroller that receives the operating signal generated by the energy source and provides a control signal to the bistable display device so that an image is generated on the label.

2. The addressable display according to claim 1, wherein the bistable display comprises at least one of:

a transducer, and an electric paper.

3. The addressable display according to claim 2, wherein the bistable display device comprises a gyricon display.

4. The addressable display according to claim 1, wherein the power source is at least one of:

a thin film battery, and an ambient energy source.

5. The addressable display according to claim 4, wherein the ambient energy source converter is a photoelectric cell.

6. The addressable display according to claim 1, wherein the bistable display detects at least one of:

a write-to function, and a read-from function.

7. The addressable display according to claim 1, wherein the bistable display retrieves at least one of:

format and access authorization, and serialization information.

8. The addressable display according to claim 1, wherein the bistable display evaluates at least one of:

content transfer, expiration date, capacity remaining in the media, errors in the media, and location of the errors in the media.

9. A user configurable bistable display useable as a label, comprising:

a bistable display device usable as a label;

a power source that generates an operating signal;

a controller that receives the operating signal and generates a control signal; and

user configurable pattern electrodes affixed to a portion of the bistable display, the pattern electrodes receiving the control signal from the controller and applying an electric field across the user selected portions of the display device.

10. A method of displaying images usable as a label, comprising:

displaying a first image on a bistable display device usable as a label, the first image including a first region displayed with a first optical characteristic which is different than a second region displayed with a second optical characteristic;

receiving the display control signal produced by a circuit, the circuit be powered by a power source; and

responsively to the control signal, displaying a second image on the bistable display device, the second image including the first and second regions, the first region being displayed in a third optical characteristic other than the first optical characteristic and the second region being displayed in a fourth optical characteristic other than the second optical characteristic.

11. The addressable display according to claim 10, wherein the bistable display comprises at least one of:

a transducer, and an electric paper.

12. The addressable display according to claim 11, wherein the bistable display device comprises a gyricon display.

13. The addressable display according to claim 10, wherein the power source is at least one of:

a thin film battery, and an ambient energy source.

14. The addressable display according to claim 13, wherein the ambient energy source converter is a photoelectric cell.

15. The addressable display according to claim 10, wherein the bistable display detects at least one of:

a write-to function, and a read-from function.

16. The addressable display according to claim 10, wherein the bistable display retrieves at least one of:

format and access authorization, and serialization information.

17. The addressable display according to claim 10, wherein the bistable display evaluates at least one of:

content transfer, expiration date, capacity remaining in the media, errors in the media, and location of the errors in the media.

18. A method of creating a display usable as a label, the method being suitable for execution proximate to a location where the display is to be deployed, the method comprising:

configuring a set of electrodes in a pattern corresponding to an image to be displayed as a label;

affixing the set of electrodes to a bistable, electrically activatable display device; and

operatively coupling the display device with the electrodes thus affixed to a power source and a controller, the controller being capable of generating a control signal for the display device using the power source.
