20080284605 | Automated Tuning Method for Rfid Labels - A method and an analogous system for tuning an RFID label prior to application to an article are disclosed. The method includes providing an RFID label having at least one antenna disposed therein, identifying an article, relaying information related to the identification of the article to a controller, with the controller including a memory of predetermined tuning parameters for the article, retrieving from memory one or more of the tuning parameters for the article; and adjusting the tuning parameters of the RFID label to correspond to the article by altering a geometric parameter of the antenna of the RFID label. The system includes a cutting device to alter a geometric parameter to correspond to the article by removing material from at least one antenna forming part of the RFID label. | 11-20-2008 |
20090027202 | RFID SYSTEM WITH INTEGRATED SWITCHED ANTENNA ARRAY AND MULTIPLEXER ELECTRONICS - An RFID detection system for determining the location of tagged items within an interrogation zone. The system includes one or more printed circuit boards coupled to each other and placed within a region of the interrogation zone. Each printed circuit board contains an antenna array having one or more antennas where each antenna detects the presence of one or more tagged items within a specific read zone in the region. The printed circuit board also contains a multiplexer coupled to the antenna array, where the antenna array and the multiplexer are provided on a substrate. Upon an interrogation request from an RFID reader, a specific antenna can be activated and selected by the multiplexer and tagged items within the antenna's read zone are interrogated. RF signals containing RF identification information are then transmitted back to the RFID reader where a host computer interprets the signals and determines the location of the identified tagged items. | 01-29-2009 |
20090045954 | Wide Exit/Entrance Electronic Article Surveillance Antenna System - An electronic article surveillance antenna system with wide interrogation zones has a number of core transceiver antennas with each connectable to a transmitter. The core transceiver antennas are adapted to be installed adjacent a ceiling of the wide interrogation zone and generate an interrogation signal into the wide interrogation zone. The core transceiver antennas each are connectable to a receiver to receive and detect a response signal from an electronic surveillance marker disposed in the wide interrogation zone. The system also has transceiver antenna coils with each connectable to the transmitter and adapted to be installed adjacent a floor of the wide interrogation zone. The transceiver antenna coils generate the interrogation signal into the wide interrogation zone and each is also connectable to the receiver to receive and detect the response signal from the electronic surveillance marker disposed in the wide interrogation zone. | 02-19-2009 |
20090189768 | COMBINATION SECURITY TAG USING A PERIMETER RFID ANTENNA SURROUNDING AN EAS ELEMENT AND METHOD THEREOF - A security tag and system for securing objects, the system and security tag includes an acousto magnetic (“AM”) electronic article surveillance (“EAS”) component that has a housing with a defined surface area. The housing of the EAS component includes a perimeter boundary that defines an EAS component plane. The system and security tag further include a radio frequency identification (“RFID”) component that includes an integrated circuit and a dipole antenna defining an RFID component plane that is substantially coplanar with the EAS component plane. The integrated circuit and the dipole antenna are positioned externally along the perimeter boundary of the EAS component. | 07-30-2009 |
20090289116 | HANDHELD COMBINATION BAR CODE AND RFID READER WITH INTEGRATED ELECTRONICS AND ANTENNA - A handheld barcode/RFID reader includes a printed circuit board having a first side and a second side opposite the first side. The first side includes at least a portion of barcode/RFID electronic circuitry affixed thereto. The second side contains a ground plane for the electronic circuitry. The handheld barcode/RFID reader further includes a patch antenna, electrically coupled to the circuitry, and mounted on the second side of the printed circuit board such that the ground plane of the printed circuit board also provides a ground for the patch antenna. | 11-26-2009 |
20110001620 | COMBINATION EAS AND RFID SECURITY TAG HAVING STRUCTURE FOR ORIENTING A HYBRID ANTENNA RFID ELEMENT - A security tag including independent EAS and RFID components disposed in a housing configured for geometric placement of the RFID and EAS components for optimum RFID performance. The EAS component is situated in a first compartment and the RFID component is situated in a second compartment. The RFID component includes a hybrid antenna RFID inlay and an IC chip. The tag housing includes a key structure that minimizes the de-tuning of both the EAS and RFID components by positioning the IC chip such that the IC chip is closer to a first side of the second compartment than the second side of the second compartment when the antenna inlay is inserted within the housing. The housing further includes one or more pins that raise the RFID inlay above the magnetic resonator of the EAS component to further insure optimal RFID read performance. | 01-06-2011 |
20120001814 | WIDE BANDWIDTH HYBRID ANTENNA FOR COMBINATION EAS AND RFID LABEL OR TAG - A radio frequency identification (RFID) antenna exhibiting a multiple resonance is disclosed. In one exemplary embodiment, a dipole antenna and a loop antenna are disposed upon a substrate and have dimensions and orientation to exhibit the multiple resonance. The dipole antenna may exhibit a first dipole section having a first length and second dipole section having a second length. The loop antenna may be disposed in a region of the dipole antenna. The ratio of the perimeter of the loop antenna to the sum of the lengths of the dipole sections may be selected to exhibit the multiple resonance. | 01-05-2012 |
20120032803 | SECURITY TAG WITH INTEGRATED EAS AND ENERGY HARVESTING MAGNETIC ELEMENT - An EAS security tag for providing both EAS and battery recharging features within one tag. The tag includes a rechargeable battery and an antenna having a magnetic core and at least one coil winding disposed around at least a portion of the core. The antenna supplies a voltage corresponding to a first frequency or a second frequency when placed within a magnetic field. The tag also includes an EAS circuit having a resonant frequency corresponding to the first frequency, and an energy harvesting circuit having a resonant frequency corresponding to the second frequency, where the battery recharging circuit recharges the rechargeable battery. Depending upon the magnetic field that the tag is exposed to, either the EAS circuit is enabled thus allowing for EAS detection or the energy harvesting circuit is enabled allowing for the battery to be recharged. | 02-09-2012 |
