Abstract

An item of print media (30) including an inductive secondary (50) for providing power to a load (32). The inductive secondary is responsive to an electromagnetic flux to generate a time-varying current or voltage therein. The current or voltage induced in the inductive secondary directly or indirectly powers the load to thereby enhance the functionality and/or the appeal of the item of print media without significantly adding to its cost. The load can provide a visual and/or auditory output, and can include an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED or an LCD display. Embodiments of the invention can be utilized in connection with a wide variety of print media, including for example books, booklets, pamphlets, labels, magazines, manuals, brochures, maps, charts, posters, journals, newspapers or loose leaf pages.

Claims

1. A secondary circuit for an article of print media having first and second sheets interconnected along a fold line, each of the first and second sheets including a cover or a page, the secondary circuit comprising:

a load supported by the first sheet;

an inductive secondary supported by the second sheet; and

an electrical conductor traversing the fold line to couple the inductive secondary to the load, wherein at least one of the first and second sheets includes print media content, and wherein the load is operable to provide a sensory output to enhance the print media content.

2. The secondary circuit of claim 1 wherein the electrical conductor includes a conductive epoxy.

3. The secondary circuit of claim 1 wherein the electrical conductor includes a plurality of conductive pads.

4. The secondary circuit of claim 1 wherein the electrical conductor includes a plurality of conductive staples.

5. The secondary circuit of claim 1 wherein the electrical conductor is adapted to withstand repeated folding or flexing along the fold line.

6. The secondary circuit of claim 1 wherein the first and second sheets include a front cover and a back cover, respectively.

7. The secondary circuit of claim 1 wherein the first and second sheets include adjacent pages.

8. The secondary circuit of claim 1 wherein the inductive secondary includes one of a wire coil and a PCB coil.

9. The secondary circuit of claim 1 wherein the load includes one of an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED and an LCD display.

22. The secondary circuit of claim 1 wherein the sensory output includes at least one of a visual output, an auditory output, and an olfactory output.

23. The secondary circuit of claim 1 wherein the print media content includes textual or graphic content.

10. A method comprising:

joining an inductive secondary to an item of print media including at least one of a cover and a page having print media content;

joining a load to the item of print media, the load being operable to provide a sensory output to enhance the print media content; and

coupling the inductive secondary to the load, wherein the inductive secondary is operable to drive the load in response to a time-varying electromagnetic field.

11. The method of claim 10 wherein the inductive secondary includes one of a wire coil and a PCB coil.

12. The method of claim 10 further including laminating the inductive secondary.

13. The method of claim 10 wherein the inductive secondary extends across a fold line.

14. The method of claim 10 wherein the load includes one of an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED and an LCD display.

15. The method of claim 10 wherein the load is adapted to release an aroma in response to an electrical current or voltage.

24. The secondary circuit of claim 10 wherein the sensory output includes at least one of a visual output, an auditory output, and an olfactory output.

25. The secondary circuit of claim 10 wherein the print media content includes textual or graphic content.

16. An item of print media comprising:

a first substrate including textual or graphic content thereon; and

an inductive secondary supported by the first substrate, wherein the inductive element is operable to drive a visual, olfactory, or auditory device in response to a time-varying electromagnetic field to enhance the textual or graphic content.

17. The item of print media of claim 16, wherein the inductive secondary includes one of a wire coil and a PCB coil.

18. The item of print media of claim 16, wherein the first substrate includes one of a page, a label, a cover, a jacket, a binding, a spine and a sleeve.

19. The item of print media of claim 16 further including a second substrate including a display area and supporting the visual or auditory device thereon.

20. The item of print media of claim 19 wherein the first and second substrates are joined along a fold line.

21. The item of print media of claim 16 wherein the visual or auditory device includes at least one of an electroluminescent display, an e-ink display, a piezo speaker coil, an electrostatic speaker, an OLED, an LED and an LCD display.
