Abstract
One embodiment is a book includes a plurality of pages, a plurality of magnets, and a sensor. The plurality of the magnets generate a combined magnetic field strength, which is variable depending on positions of the pages on which the magnets are disposed. The sensor senses the combined magnetic field strength and generates a varying signal based on a varying of the combined magnetic field strength when at least one page is moved. The varying signal indicates a position of at least one page in the book.
Claims17
A book, comprising:
- a plurality of pages;
- a plurality of magnets, wherein each magnet is disposed on a pre-determined location of each of at least two of the plurality of pages and generates a magnetic field, the plurality of the magnets generate a combined magnetic field strength, the combined magnetic field strength is variable depending on positions of the pages on which the magnets are disposed;
- and
- a sensor that senses the combined magnetic field strength and generates a varying signal based on a varying of the combined magnetic field strength when at least one page is moved, wherein the sensor comprises a sensor magnet;
- wherein a load is provided in the book at a position juxtapose the sensor magnet, wherein the sensor is a pressure sensor that measures the combined magnetic field strength acting on the sensor magnet against a preloading force produced from the load;
- and
- wherein the varying signal indicates a position of at least one page in the book.

A method that indicates a page of a book that is currently open, wherein the book includes a plurality of pages, the method comprising:
- providing a first sensor comprising a first sensor magnet in the book, and a second sensor comprising a second sensor magnet in the book;
- producing, by a plurality of magnets with each magnet disposed on at least two of the plurality of pages, a first combined magnetic field strength and a second combined magnetic field strength that act on the first sensor magnet and the second sensor magnet respectively, wherein the first combined magnetic field strength and the second combined magnetic field strength are variable depending on positions of the pages on which the magnets are disposed;
- sensing, by the first sensor in the book, the first combined magnetic field strength that acts on the first sensor magnet;
- generating, by the first sensor, a first signal based on the first combined magnetic field strength;
- sensing, by the second sensor in the book, the second combined magnetic field strength that acts on the second sensor magnet;
- generating, by the second sensor, a second signal based on the second combined magnetic field strength;
- and
- indicating, based on the difference between the first signal and the second signal, the position of the page of the book that is currently open.

A book, comprising:
- a plurality of pages;
- a first sensor magnet disposed at a back cover page of the book;
- a second sensor magnet disposed at a front cover page of the book;
- a plurality of magnets, wherein each magnet is disposed at the plurality of pages and generates a magnetic field, one or more of the magnets generate a first combined magnetic field strength and/or a second combined magnetic field strength that act on the first sensor magnet and/or the second sensor magnet respectively, the first combined magnetic field strength and the second combined magnetic field strength are variable depending on positions of the pages on which the magnets are disposed;
- a first sensor in the book that measures the first combined magnetic field strength and generates a first signal based on the first combined magnetic field strength;
- and
- a second sensor that measures the second combined magnetic field strength that acts on the second sensor magnet and generates a second signal based on the second combined magnetic field strength,
- wherein the first signal determines a position of at least one page in the book wherein a difference between the first signal and the second signal indicates the position of at least one page in the book.
