Abstract: An electronic book (ebook) lending system for requiring at-library book activation. The lending system includes a central system for managing and hosting ebooks, the central system including a storage device and a processor to control a user interface that enables a user to interact with the central system. The central system also includes an access device for activating ebooks at the library. A user may reserve an ebook through the user interface accessed by a remote user device or a library device. The content of the ebook is inaccessible to the user until the ebook is activated, wherein a user may activate the ebook by providing user identification information to the access device, and after the ebook is activated, the user may access the content of the ebook remotely. The present disclosure further includes an ebook lending system for incentivizing library visits by patrons and a digital content lending system for requiring at-library digital content activation.

Abstract: Techniques for detecting radio-frequency identification (RFID) tags are disclosed. For example, an exit control system is described that detects unauthorized removal of articles from a protected facility. A series of antennas are setup to produce interrogation corridors located near the exit of the protected area. RFID tags are attached to the articles to be protected. Each tag includes information that uniquely identifies the article to which it is affixed and status information as to whether the articles removal from the facility is authorized. The RF reader outputs RF signals through the antennas to create electromagnetic fields within the interrogation corridors. The reader outputs RF power from a single port to the multiple antennas via a splitter/combiner. In this way, a single RF reader with only one transmitter/receiver port simultaneously interrogates multiple antennas. A variety of techniques are described by which the reader can detect the removal of an unauthorized article.
