Patent number: 7978078Abstract: A magnetic core transceiver antenna for EAS marker detection is provided. The core includes a stack of amorphous alloy ribbons insulated from each other and laminated together. A coil winding of wire, also insulted from the ribbons, and connected to an electronic controller provides the transmitter and receiver modes. The transceiver antenna is optimized for the dual mode operation, and is smaller and uses less power than conventional air-core EAS antennas with equivalent performance. Complex core geometries, such as a sandwiched stack of different sized ribbons, can be implemented to vary the effective permeability of the core to customize antenna performance. Multiple transceiver antennas can be combined to increase the size of the generated EAS interrogation zone.Type: GrantFiled: December 21, 2001Date of Patent: July 12, 2011Assignee: Sensormatic Electronics, LLCInventors: Richard L. Copeland, Brent F. Balch, Steven W. Embling, William M. Farrell, Stewart E. Hall

Patent number: 7973661Abstract: A detacher unit for disengaging a combination EAS/RFID tag from its article. The detaching unit detaches the spring clamp mechanism of a combination EAS/RFID tag when the tag is placed within a particular region within the detaching unit. A near field magnetic loop antenna is situated within the placement region in a housing. When the combination EAS/RFID tag is placed within the placement region just above the near field magnetic loop antenna, the RFID code of the tag is read and the detachment unit releases the clamp mechanism that attaches the EAS/RFID tag to its article.Type: GrantFiled: March 6, 2008Date of Patent: July 5, 2011Assignee: Sensomatic Electronics, LLCInventor: Richard L.

Publication number: 20110001620Abstract: 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.Type: ApplicationFiled: June 24, 2010Publication date: January 6, 2011Applicant: SENSORMATIC ELECTRONICS, LLCInventors: Richard L.

Publication number: 20090027202Abstract: 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.Type: ApplicationFiled: July 27, 2007Publication date: January 29, 2009Applicant: SENSORMATIC ELECTRONICS CORPORATIONInventors: Richard L.
