  • Patent number: 7290700
    Abstract: A system for displaying audio content with text including a book holder and a book. The book holder identifies which book of a plurality is placed in the holder by detecting magnetic indicators in specific locations and arrangements which are unique to each book. The page of the book which a user views at any given time is identified by detection of ambient light, by detection of a number of circuit elements in parallel, by detection of progressively stacked magnetic sensors, or by microwave reflection.

  • Patent number: 7201317
    Abstract: A system for illustrating sound and text including a book with pages having illustrations and/or text, at least some of the pages including a magnetic signature; a book holder adapted to accept the book, the book holder having a reading surface with a magnetic signature sensor, cartridge slot, a reading controller, a speaker, and a power supply; and a cartridge adapted to be inserted in the cartridge slot, the cartridge including stored audio representations related to the illustrations and/or text of the pages; wherein the magnetic signature sensory is predisposed to detect and make direct contact with the magnetic signature on the pages as they are turned by a user viewing the book, and wherein the reading controller is adapted to interact with the magnetic signature sensory to determine a given page that the user is viewing responsive to the direct contact between the magnetic signature sensor and the magnetic signature on the given page, and to retrieve audio representations and/or text stored on the cart

  • Patent number: 6763995
    Abstract: A method and system (10) for illustrating sound and text comprising a book (18) with pages (20) including illustrations and/or text, wherein at least some of the pages (20) include magnetic signatures (24). The system further includes a book holder (12) adapted to accept the book (18). As such, the book holder (12) has a reading surface (14) with a magnetic signature sensor (16), a cartridge slot (36), a reading controller (42), a speaker (44), and a power supply (46). The system also comprises a cartridge (34) adapted to be inserted in the cartridge slot (36). The cartridge (34) includes stored audio representations related to the illustrations and/or text of the pages (20). The magnetic signature sensor (16) is predisposed to detect the magnetic signatures (24) on the pages (20) as they are turned by a user viewing the book (18).
