Gathering data concerning publication usage
First Claim
Patent Images
1. A system for producing data concerning usage of a publication by a person, comprising:
- a piezoelectric element disposed in or on a predetermined portion of a publication and operative to produce as an output electrical energy when deformed; and
a communication device disposed in or on the publication and responsive to the electrical energy output by the piezoelectric element to communicate data indicating usage of the publication to a data receiver apart from the publication.
