Patent number: 7068172Abstract: A deactivator for deactivating label-style EAS devices is claimed. The preferred embodiment, of which, employs a microprocessor unit to control two transceiver coils, and a deactivation coil in series with a capacitor. The two transceiver coils are essentially two flat figure eights arranged concentrically but rotated through some angle with respect to each other. The transceiver coils are operated alternatively, first transmitting an interrogation signal and then listening for a response. When an EAS device is detected, the microprocessor unit drives the capacitor and deactivation coil at the system's resonant frequency to generate a high amplitude magnetic field then shifts the frequency of the driving current away from the resonant frequency to attenuate the magnetic field. A field sensor or current sensor provides feedback to the microprocessor to determine the resonant frequency of the system during a frequency sweep.Type: GrantFiled: May 21, 2004Date of Patent: June 27, 2006Inventors: Xiao Hui Yang, Arthur Bradley Fuss

This opposite side of the support is designed to be secured to a conductive surface via an insulating dielectric layer. The labels are designed to be affixed on products having conductive surfaces such as laser discs, gas bottles and the like.Type: GrantFiled: September 11, 2001Date of Patent: September 27, 2005Assignee: GemplusInventor: Philippe Martin

Patent number: 6933848Abstract: The disclosed embodiments of the present invention are used to permanently disable or destruct an RFID so that it is no longer possible to read some or all of the data encoded on the RFID tag. In one method for disabling data on a radio frequency identification (RFID) tag, an RFID tag is identified and its identity is confirmed. Verification that a prerequisite event has occurred is obtained, occurrence of which is required prior to disablement of the data. A destruct instruction is transmitted to the RFID tag. The RFID tag verifies that the destruct instruction is valid and disables the data upon verifying validity of the destruct instruction. The tag may disable the data by erasing the data, disabling the data, auto-destructing, or performing any operation that makes the data unreadable.Type: GrantFiled: May 7, 2002Date of Patent: August 23, 2005Assignee: Alien Technology CorporationInventors: Roger G. Stewart, John Rolin, Curtis Carrender

Patent number: 6933844Abstract: A security seal for a freight car, freight container or other enclosure. The seal has an electronic timepiece which displays the time and date and is preset at an established reference time. A cut-resistant strap is secured at one end to the seal and has a latch at the other end. When the latch is passed through a lock and is engaged in a receiver in the seal, the strap is locked in place and the power to the timepiece is interrupted providing an indication of the time and date on which the lock was sealed. Other information may be applied to the seal at the time of sealing such as the identification of the individual responsible for the sealing.Type: GrantFiled: March 10, 2003Date of Patent: August 23, 2005Inventors: Quent Augspurger, James W. Hill

Patent number: 6919793Abstract: A Write Broadcast system and method uses a base station to write sent data to all or some selected number (sub group) of tags in a base station field simultaneously. By unselecting the tags that have been successfully written to, and requesting a response from the remaining tags in the field (or sub group), the system determines, by receiving a response to the request, that there are tags in the field (sub group) that were unsuccessfully written to. Another Write Broadcast signal is sent to these tags. The system is useful for quickly (simultaneously) “stamping” information on the tag memory of a large number of tags in the field of the base station.Type: GrantFiled: August 24, 1999Date of Patent: July 19, 2005Assignee: Intermec IP Corp.Inventors: Harley Kent Heinrich, Christian Lenz Cesar, Thomas A. Cofino, Daniel J. Friedman, Kenneth Alan Goldman, Sharon Louise Greene, Kevin P. McAuliffe

Patent number: 6919806Abstract: A deactivation apparatus for an electronic article surveillance tag having a plurality of layers and an equivalent resonant circuit containing an inductor and a capacitor is provided. The apparatus includes: a capacitor formed by a pair of conductive capacitor plates separated apart by a dielectric layer; an inductor connected to each of the pair of capacitor plates where an electromagnetic field of a preselected frequency at a first magnitude impinging upon the tag causes the equivalent resonant circuit to resonate and produce a detectable response from the tag; and, an electrically weakened area in the dielectric layer between the pair of conductive capacitor plates where the electromagnetic field at a second magnitude higher than the first magnitude impinging upon the tag causes a conductive path through the weakened area electrically connecting the pair of capacitor plates together and deactivating the tag.Type: GrantFiled: September 6, 2002Date of Patent: July 19, 2005Assignee: Sensormatic Electronics CorporationInventors: Douglas Narlow, Hubert A. Patterson

Patent number: 6864792Abstract: An electronic key capable of reinitializing or resetting a security disabled electronic article surveillance (EAS) device is provided. The electronic key can be a secure, portable, and battery powered for initializing a secured EAS system's security protocol to factory default state, or to another preselected state. The key has its own set of security protocols to prevent unauthorized use and can easily be reprogrammed for a wide variety of other functions including, but not limited to, firmware upgrading, diagnostic testing, and the like. The key can be connected to the programming port of an EAS device and perform a preset reprogramming operation, resetting activated security features. The key could be purchased for customer use, and would be secured by preselecting the total number of uses, such as one use. The one-time use would begin once the key is activated. Activation of the key is also uniquely controlled to prevent its misuse.Type: GrantFiled: September 6, 2002Date of Patent: March 8, 2005Assignee: Sensormatic Electronics CorporationInventors: Rich Labit, Steven R. Maitin, Carl A. Brooks, Larry Canipe

Publication number: 20040263319Abstract: A system, apparatus and method for supporting multiple reader-tag configurations and reader-tag distances using a single multi-mode tag. A multi-mode radio frequency (RF) transponder is provided, which includes operational tag circuitry configured to provide information in response to being activated by a reader device(s). Multiple antenna circuits are coupled to the operational tag circuitry, where each of the antenna circuits is configured to operate at a different reader-tag distance. At least one disabling circuit is coupled to the operational tag circuitry and to at least one of the antenna circuits, where the disabling circuit is configured to disable operation of at least one of the antenna circuits to which it is coupled.Type: ApplicationFiled: June 30, 2003Publication date: December 30, 2004Applicant: Nokia CorporationInventor: Heikki Huomo

Patent number: 6819245Abstract: Vehicle security systems comprise at least one addressable transponder for communication with at least one base station. Each transponder and base station comprises a steerable directional antenna having an antenna azimuth sensor. Transponder and base station antenna azimuths assist in locating a vehicle carrying a transponder and allow near real-time estimation of vehicle heading. Base station networks facilitate location, tracking and/or interception of vehicles within a network geographic area. Use of multiple effective transmission ranges for transponders and/or base stations improves the accuracy of vehicle location.Type: GrantFiled: May 27, 2002Date of Patent: November 16, 2004Inventor: Emery W.
