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.

Claims (5)

1. A system for displaying audio with text, comprising: a book having pages bound together between front and rear covers, a book holder accepting said book, the book having electrical components attached to at least some of the pages, the electrical components of different pages being electrically connected in parallel when the different pages are overlaid to form a circuit; wherein when a first set of the pages are overlaid, an electrical characteristic assumes a first value at a point in the circuit; and wherein when a second set of the pages are overlaid, the electrical characteristic assumes a second value at the point in the circuit, said book being in electrical communication with said book holder when accepted.

2. The system of claim 1 , wherein the electrical characteristic is a voltage value.

3. A system for displaying audio with text, comprising: a book holder designed to receive a book, the book having a plurality of pages; electrical components attached to at least some of the pages, the electrical components of different pages being electrically connected in parallel when the different pages are overlaid to form a circuit; wherein when a first set of the pages are overlaid, an electrical characteristic assumes a first value at a point in the circuit; and wherein when a second set of the pages are overlaid, the electrical characteristic assumes a second value at the point in the circuit, wherein the electrical characteristic is the duration of a voltage pulse width.

4. The system of claim 3 , wherein the electrical components are capacitors.

5. The system of claim 3 , wherein the pulse width is compared to a reference pulse width.
