Publication number: 20080238680Abstract: A radio frequency identification (RFID) tag may have a non-responsive mode, triggered by a command from an RFID reader, that temporarily prevents the RFID tag from responding to a query from any RFID reader for a period of time. In some embodiments this non-responsive mode may automatically end after a certain period of time without further action by the RFID reader. In other embodiments this non-responsive mode may end when directed to by another command addressed specifically to the RFID tag.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Inventors: Joshua D. Posamentier, Joshua R. Smith

Patent number: 7429920Abstract: Systems and methods for radio frequency identification and tagging of implantable medical devices and their components are disclosed. A preferred embodiment includes tagging a device and its components with manufacturing information relating to the device and it components and with information identifying a patient using the device. The information can be automatically transmitted or extracted from the device when the device or its components come into communication range of an external programmer or other device adapted to read or sense the RFID information. Some embodiments of a system disclosed herein can also be configured as a component of an Advanced Patient Management System that helps better monitor, predict and manage chronic diseases.Type: GrantFiled: July 20, 2005Date of Patent: September 30, 2008Assignee: Cardiac Pacemakers, Inc.Inventors: Alan H. Smythe, Howard D. Simms, Jr., Kenneth P. Hoyme

Patent number: 7425898Abstract: A self adhesive label including a removable RFID tag. The multi-layer label includes a content label and a base label. A removable portion of the content label includes an RFID tag. An exposable portion of the base label is exposed when the removable portion of the content label is removed. The exposable portion of the base label includes markings substantially similar to markings on the removable portion. A related method includes the steps of permanently applying a label to an article in which the label includes a removable RFID tag; utilizing the RFID tag while applied to the article; and subsequently removing the RFID tag without substantially damaging the label before further transfer of the article.Type: GrantFiled: June 1, 2006Date of Patent: September 16, 2008Assignee: CCL Label, Inc.Inventor: Robert W. Ryckman

Patent number: 7425897Abstract: An RFID device is capable of stopping and restarting a response via a response stop command. The device is capable of initializing a part of or the whole of internal data including a response restart set data storage portion. The device is capable of using command data from an external communication equipment to look up response restart data at the restart of a response, deciding a data storage area and content that may be initialized when the restart is possible, and rewriting a data storage portion.Type: GrantFiled: March 27, 2006Date of Patent: September 16, 2008Assignee: Hitachi, Ltd.Inventors: Shinichiro Fukushima, Yutaka Takami, Masumi Moritani

Publication number: 20080204247Abstract: An integrated electronic article surveillance (EAS) and radiofrequency identification (RFID) marker is provided which a semiconductor device which may he coupled to an antenna for receiving and retransmitting energy and signals to the antenna. A current receiving front end section of the semiconductor device communicates with at least one other section of the device so more than one function can be implemented upon receiving and retransmitting energy and signals. A first switch is operatively coupled to the front end section such that the functions are entirely but reversibly disabled upon closure of the first switch thereby effecting a reversible EAS function. A second switch is operatively coupled to the front end section such that at least one of the functions is at least partially disabled upon closure of the second switch. RFID functions of the marker am retained upon EAS deactivation.Type: ApplicationFiled: November 18, 2005Publication date: August 28, 2008Applicant: SENSORMATIC ELECTRONICS CORPORATIONInventors: Ming-Ren Lian, Gary Mark Shafer
