Abstract:
A magnetic article surveillance system in which surveillance is carried out by operating the system in first and second different modes of a magnetic transmitting and receiver means in order to make a determination as to the presence of an article in the zone.
Abstract:
Una etiqueta de seguridad reutilizable que comprende una estructura de alojamiento similar a una pinza elástica que tiene dos brazos que están unidos entre sí por un extremo formando un ángulo agudo predeterminado, cuyo ángulo se mantiene en ausencia de cualquier flexión de dichos brazos; estando dicha estructura construida y dispuesta para ser deformable elásticamente mediante tal flexión de por lo menos uno de dichos brazos para permitir que los extremos libres de dichos brazos sean llevados a juntarse por presión manual directa.
Abstract:
A surveillance assembly wherein the assembly utilizes a solid state image pickup which is separately mounted from a camera body of a solid state camera and wherein a shutter is utilized for shielding the viewing region of the assembly.
Abstract in simplified Chinese:本发明提供一种于一控制区内,由监视区至监视区追踪与通过电子方式识别资产之系统。一触发事件可以是一 RFID阅读机之输出,或其他事件,初始化该资产之视频追踪与该RFID标签或其他触发器有关。当该资产之影像从摄影机交递至摄影机,该视频监视继续从区至区。该资产之影像与该资产身分一起有选择性地被显示与纪录。该系统使用复数个不同之触发感应器与视频摄影机,是有弹性且可程控用于复数种不同的环境与监视区。

Abstract:
A method, system and computer program product for filtering a RFID signal. At least one pre-operational interference signal is measured. Amplitude and frequency data are extracted from the at least one measured pre-operational interference signal. At least one filter-dependent parameter is computed based at least in part on the extracted amplitude and frequency data extracted from the measured at least one pre-operational interference signal. A table is generated during a pre-operational mode. The table has at least one set of filter coefficients based on the computed at least one filter-dependent parameter.
Abstract:
A method, device and system for radio frequency identification ("RFID") performance analysis. An analyzer for analyzing the performance of an RFID reader is provided. The analyzer has an interface in communication with the reader. A processor is in communication with the interface. The processor operates to use the interface to monitor communication with the reader and/or simulate one or more RFID tags.

Abstract:
A system and method for controlling door-mounted or door-embedded antennas. An antenna, for example, an EAS or an RF antenna, sends interrogation signals which are received by markers located on merchandise within a range of detection, i.e., an "interrogation zone". Antennas that are mounted on or embedded in a door move along with the motion of the door. Thus, the interrogation zone covered by the antenna's magnetic field is continually changing with the movement of the door. The system and method of the present invention control door-mounted antennas by monitoring the motion of the door upon which the antenna is mounted, and by adjusting the size and breadth of the interrogation zone generated by the antenna accordingly. A processor within a control unit receives positional signals from a position sensor mounted on the moving door, determines whether the interrogation zone should be increased, decreased, shut off, or maintained, and transmits signals to the antenna or to an alarm device, the signal containing interrogation zone modification instructions.
Abstract:
A magnetoniechanical tag for use in an electronic article surveillance (EAS) system and a method of manufacturing the magnetomechanical tag may be provided. The EAS may include at least one resonator, a housing configured to allow vibration therein of the at least one resonator and a cover heat sealed to the housing at a heat sealing temperature. The EAS tag further may include a powder lubricant within the housing. The powder lubricant may have a melting temperature less the heat sealing temperature.
