  • Patent number: 7961096
    Abstract: A system for detecting electronic article surveillance marker shielding includes electronic article surveillance (“EAS”), metal detection and video analysis subsystems communicatively coupled to a system controller. The EAS subsystem detects EAS markers within a detection zone. The metal detection subsystem detects metallic objects within the detection zone. The video analysis subsystem captures a video image of the metallic object. The system controller determines a probable classification for the metallic object and calculates a confidence weight for the probable classification. If the metallic object is identified as EAS marker shielding according to the probable classification and the corresponding confidence weight, an alert is generated.

  • Publication number: 20110113437
    Abstract: An apparatus, system and method discourage theft of a media disc. The media disc has a central aperture and is retained within a media disc case by an inner spindle that extends through the central aperture. A pin is insertable through the inner spindle. A locking clutch is operable to engage the pin. When engaged, the locking clutch secures the media disc upon the inner spindle and prevents the media disc from being removed from the inner spindle. A liquid-dispensing container is positioned between the pin and the media disc such that when a force is exerted upon the media disc to attempt to remove the disc from the inner spindle when the locking clutch is engaged, the liquid-dispensing container releases a liquid which renders the media disc unreadable.

  • Publication number: 20110050400
    Abstract: A system and method selectively reads radio frequency identification (“RFID”) tags within an RFID interrogation zone. A portion of the RFID tags have a first operating range and a portion of the RFID tags have a second operating range that is different from the first operating range. Each RFID tag is programmed with an identifier associated with the operating range of the RFID tag. A first interrogation signal is transmitted which has sufficient power to activate RFID tags that are located within the RFID interrogation zone and have the first operating range. A response signal is received from each RFID tag capable of receiving the first interrogation signal. Each response signal indicates the identifier of the associated RFID tag. Each RFID tag that has an identifier associated with the first operating range is selected.

  • Publication number: 20110025498
    Abstract: A method and system are provided for adjusting a threshold value of an alarm for a metal detecting system, based on a detected interference with other systems that operate at adjacent frequencies. The method and system include receiving a plurality of sample values and calculating a discrepancy value based on a difference between a maximum value and a minimum value of the plurality of sample values, wherein the discrepancy value corresponds to detected interference. The discrepancy value is compared to a predefined interference threshold value and an activation signal is generated. A fast threshold adjustor receives the activation signal when the discrepancy value is greater than or equal to the predefined interference threshold value and a slow threshold adjustor receives the activation signal when the discrepancy value is less than the predefined interference threshold value.

  • Publication number: 20100308998
    Abstract: An EAS tag is provided having improved anti-defeat devices and methods. A pin assembly is coupled to a lanyard and includes a reduced cross-sectional profile that may be passed through a monitored article to produce no damage or minimal damage to the monitored article. The pin assembly engages a spring clamp provided in the EAS tag and is electrically coupled to an intermediate spring contact that provides an electrical current to a PC board for arming the EAS tag. A force may be applied to the intermediate spring contact to generate a reset signal that disarms the EAS tag. An alarm signal is generated if current to the PC board is disrupted without a corresponding reset signal, such as if the pin assembly is removed without rotating the intermediate spring contact or if the lanyard is cut. The tag body is provided with an arcuate channel through which an arcuate detacher probe can be guided for releasing the attaching assembly part.

  • Publication number: 20100148969
    Abstract: A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet.

  • Publication number: 20100141451
    Abstract: An Electronic Article Surveillance (“EAS”) tag and method and system for deactivating EAS tags without the need to physically contact the tag with a deactivation device. The EAS tag replaces the conventional diode with a non-linear device such as a metal-oxide-semiconductor (“MOS”) capacitor with a given breakdown voltage threshold. Inducing a predetermined voltage across the MOS capacitor results in destruction of the MOS capacitor rendering the EAS tag undetectable in the EAS interrogation system.
