Abstract:
A security tag (10) including independent EAS (16) and RFID (18) components disposed in a housing (12) configured for geometric placement of the RFID and EAS components for optimum RFID performance. The EAS component (16) is situated in a first compartment (17) and the RFID component (18) is situated in a second compartment (19). The RFID component includes a hybrid antenna RFID inlay (24) and an IC chip (30). The tag housing (12) includes a key structure (38) that minimizes the de-tuning of both the EAS (16) and RFID components (18) by positioning the IC chip (30) such that the IC chip (30) is closer to a first side (25) of the second compartment (19) than the second side (21) of the second compartment (19) when the antenna inlay (24) is inserted within the housing (12). The housing (12) further includes one or more pins that position the RFID inlay (24) closer to the bottom interior surface to further insure optimal RFID read performance.
Abstract:
An anti-theft security system that utilizes an electronic article surveillance (EAS) beacon that emits an electromagnetic field that a corresponding security tag transponder detects in determining whether to set off onboard transponder alarms or to remain dormant. The EAS beacon is a self-contained beacon that can be easily installed at any desired location and can utilize local utility power or revert to battery power. Among other things, this avoids the large installation, calibration and maintenance costs and tasks of conventional EAS pedestals. The EAS beacon includes coil panels that are secured to an elongated housing that can be flexed to avoid or minimize damage should something or someone come into contact with the panels. An audible/visible alarm is activated when such flexing or tampering occurs. A passive infrared detector is provided to reduce power consumption when the EAS beacon is operating on battery power. The EAS beacon may also be used in existing EAS and RFID anti-theft security systems wherein the associated security transponder also includes passive EAS and/or RFID security elements. A wireless disable key can also be used to shut off an alarming transponder.

Abstract:
A method, system and electronic article surveillance tag deactivator detect the presence of an electronic article surveillance tag within a deactivation zone. Video of an item within the deactivation zone is captured. The video is evaluated using a pattern recognition technique to determine the presence of an electronic article surveillance tag within the deactivation zone. The electronic article surveillance tag is deactivated.
Abstract:
A system for detecting electronic article surveillance ("EAS") marker shielding includes an EAS subsystem (10), a metal detector (18), a people counting system (20) and a processor (16). The EAS subsystem (10) operates to detect an EAS marker in an interrogation zone. The metal detector (18) operates to detect a metal object in the interrogation zone. The people counting system (20) operates to detect one or more people in the interrogation zone. The processor (16) is electrically coupled to the EAS subsystem (10), the metal detector (18) and the people counting system (20). The processor (16) is programmed to receive information outputted from the people counting system (20) and information outputted from the metal detector (18) to determine whether to generate an alarm signal based on the presence of EAS marker shielding.

The invention is directed to a Walk through Metal Detector's detection data transferring & displaying methodology mixed with composite video signal and logging the data concerning the detection of the system superimposed on the video with time stamp. The invention includes a Microcontroller based portable computer having manual & automatic inputs coming from a data port. An auxiliary processor or module is used at the output side to superimpose the data with composite video signal coming from a camera output. The system data like Sensitivity, Thresh Hold and Metal Level, these three parameters are being displayed at a time for all the zones on a Alpha Numeric LCD /Graphic LCD and on the Monitor with the composite video signal to enable a comparative study of the zone detection.
Abstract:
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.
Abstract:
A resonant tag for use with a radio-wave detection system for the prevention of shoplifting or the like, which has a coil and capacitor circuit formed on opposite sides of an extremely thin substrate of a biaxially-oriented polypropylene, with one of the capacitor plates formed on one side of the substrate and the coil and other capacitor plate formed on the other side of the substrate, and paper layers on both sides of the tag, whereby the circuit is destroyed when the tag is washed in water or dry cleaned.

An anti-theft device for containers of fluid products comprising: a support element (3) connected to a container (2) to be monitored and attached to the inside of a neck (6) of container (2), between the neck (6) itself and a closure member (11) which is irremovably attached to container (2); and a circuit (7) at least partially housed in said support element (3) to receive an enquiry signal (Sl) and to generate a corresponding response signal (S2).
Abstract:
This invention relates to dynamically controlled, electronic article surveillance (EAS) systems whereby an array of antenna elements is digitally phased and actively driven for concurrent transmission, and digitally phased and combined in the receiver unit to improve security tag detection. In particular, the individual frequency and phase of the plurality of the transmit/receive signals are rapidly varied to allow for automated manipulation (steering) of the transmit field pattern and receive field sensitivity. It is the object of this invention to achieve the following features via means of digital phasing and dynamic computer control: sufficient far-field cancellation, null-free detection and uncompromised detection performance regardless of tag's orientation.
