PRINT MEDIA WITH INDUCTIVE SECONDARY

摘要

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 indude 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.
