Publication number: 20100279056Abstract: The invention may include a novel composition for and/or processing of an active element for an EAS marker that achieves the same or better performance of existing materials while solving the problem of higher cost. It may include a magnetomechanical active element formed by planar strip of amorphous magnetostrictive alloy having a composition FeaNibMc wherein a+b+c=100, wherein a is in a range of 40-70 weight percent, b is in a range of 10-50 weight percent, and c is in a range of 10-50 weight percent, and where M is the balance of remaining elements; wherein the magnetomechanical active element is subject to batch annealing in the presence of a magnetic field that is substantially transverse to the ribbon length of the element and at a temperature of less than about 300° C. and for a time greater than at least about one hour.Type: ApplicationFiled: June 7, 2007Publication date: November 4, 2010Applicant: Sensomatic Electronics CorporationInventors: Ming-Ren Lian, Nen-Chin Liu, Chaitali China, Kevin R. Coffey

Publication number: 20100148962Abstract: An embodiment is an EAS tag that may be included in an EAS system. More specifically, an embodiment is a reusable EAS tag including an arcuate channel with an L-shaped keyway, into which an appropriate corresponding tool, in the form of an arcuate probe, can be inserted for releasing a clamp and thereby detaching the EAS tag from its article. Prevents tampering and activation of the detaching mechanism with other tools than the intended one.Type: ApplicationFiled: November 23, 2007Publication date: June 17, 2010Applicant: Sensomatic Electronics CorporationInventor: Thang Tat Nguyen

Patent number: 7495565Abstract: A method for controlling electronic article surveillance (EAS) transmissions is described. The method includes calculating system parameters associated with one or more of a desired frequency, a desired duty cycle, and a desired phase difference between antennas for a transmitter, and initializing a counter with a value based on the system parameters. The method also includes comparing a count from the counter to the system parameters, and modulating EAS transmission signals based on the comparison between the count and the system parameters. An EAS transmitter and an EAS system are also described.Type: GrantFiled: May 4, 2005Date of Patent: February 24, 2009Assignee: Sensomatic Electronics CorporationInventors: Jeffrey T. Oakes, Thomas J. Frederick, Richard L. Herring

Publication number: 20090045954Abstract: 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.Type: ApplicationFiled: February 21, 2006Publication date: February 19, 2009Applicant: Sensomatic Electronics CorporationInventors: Stewart E. Hall, Richard L. Copeland, William Farrell

Publication number: 20090009296Abstract: A radiofrequency identification (RFID) multiplexer, which may be in a network, interprets an RF signal from an RFED reader as RFE) tag interrogation data. A single cable directs an RF signal from the RFID reader and RF control signals and/or RF power through the multiplexer. An RF sampler may be coupled to the cable; and an RF detector detects the RF signal from the cable via the RF sampler. A data decoder decodes and interprets the RF signal as the RFID tag interrogation data and forwards the RFID tag interrogation data to a control logic circuit as a MUX channel-change command. The logic circuit and decoder may be combined in a microcontroller, and an RF backscatter modulator coupled to the cable enables reverse communication with the RFID reader to determine whether another RFID multiplexer is coupled to the RFID multiplexer.Type: ApplicationFiled: February 15, 2006Publication date: January 8, 2009Applicant: Sensomatic Electronics CorporationInventor: Gary Mark Shafer

Publication number: 20080303902Abstract: A method and system detects potential suspicious behavior in a monitored facility. The monitored facility includes at least one point of transaction terminal. Video content of an activity occurring at the monitored facility and transaction data relating to a transaction processed at the transaction terminal are collected. The video content is correlated with the transaction data to produce correlated data. A set of user-defined rules are applied to the correlated data. Responsive to identifying a match between the correlated data and at least one rule of the set of user-defined rules, the transaction is determined to be potentially suspicious.Type: ApplicationFiled: June 9, 2008Publication date: December 11, 2008Applicant: Sensomatic Electronics CorporationInventors: Kevin Douglas ROMER, Shuhai SHEN, Amber Marsel HEROLD

Publication number: 20080007457Abstract: A near field linear element microstrip antenna is disclosed which is configured to read an RFID label such that a localized electric E field emitted by the antenna at an operating wavelength resides substantially within a zone defined by the near field. The localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.Type: ApplicationFiled: November 2, 2005Publication date: January 10, 2008Applicant: Sensomatic Electronics CorporationInventors: Richard Copeland, Gary Shafer
