Abstract: A radio frequency identification (RFID) device programming system and method may be used to provide pre-programmed RFID devices, for example, as a roll of RFID devices that may be later applied to articles or items. The programming system may include a plurality of RFID probes configured to apply programming signals to the RFID devices and a RFID programmer connected to the probes and configured to generate the programming signals. The programming system may also include a web positioning mechanism configured to position a web including the RFID devices such that the group of RFID devices is positioned in within a programming range of the probes. A controller may be configured to control the web positioning mechanism such that sequential groups of the RFID devices are programmed.

Abstract: The invention relates to an RFID label applicator (100) may include a peeler member (140) having a peel end (142), the peeler member being configured to cause an RFID label (102) to peel away from a web (110) when the web passes around the peel end; and a label tamp assembly (150) having a receiving surface (612) configured to receive the RFID label and to move it into contact with an item (104) on which the RFID label is to be applied, the label tamp assembly having at least one forward opening in a portion of the receiving surface away from the peeler member and a plurality of rearward openings in a portion of the receiving surface proximate the peeler member, wherein at least one of the forward or rearward openings is configured to draw in air such that a leading portion of the RFID label is substantially secured.
Abstract: A video image data reduction system through the use of object tracking reduces information in a video signal having a having a plurality of frames received from a motion video camera with a field of view. Moving objects in the field of view of the motion video camera are detected. These objects are selected if they are of interest. This is determined either by comparison of the detected object against predetermined characteristics of objects of interest or by manual user selection. A data set for each frame of the plurality of frames in the video signal is created based on the selected moving objects. If a frame contains no selected objects then the data set for that frame is marked as empty.
Abstract: A system and method of managing assets using a combined electronic article surveillance (EAS) and barcode scanning device. The combined EAS/Scanner is portable and wirelessly connected to a network for facilitating a number of asset management functions, including personal shopping, pre-checkout, data mining, and inventory tracking.
Abstract: A method according to one embodiment may include detecting an activated electronic article surveillance (EAS) tag in an interrogation zone, and reading at least one radio frequency identification (RFID) tag in response to the detecting of the activated EAS tag in the interrogation zone to investigate a cause of the EAS tag in said interrogation zone. A method according to another embodiment may include detecting a condition representative of an activated RFID tag in a controlled area, and taking corrective action to prevent removal of the activated RFID tag from the controlled area.
Abstract: A method for controlling operation of a transmitter in an electronic article surveillance (EAS) system is described that includes coupling each of a plurality of transmit channels to a corresponding antenna, configuring a modulator within each transmit channel to output a modulated signal to the corresponding antenna, providing feedback of each modulated signal, and adjusting operation of each modulator based on the feedback. An EAS transmitter and an EAS system are also described.

Abstract: A near field meanderline like antenna assembly is disclosed which is configured to read an RFID label. The antenna is configured as a single and continuous conductor and is configured to extend from one end of a substrate forming a feed point to another end of a substrate forming a termination point. The termination point is connected to a ground through a resistor and the conductor is configured to direct current in two dimensions along the conductor. A localized E field directs a current distribution along an effective length of the antenna corresponding to a half-wave to a full-wave structure.
Abstract: A security device detaches a combination electronic article surveillance (EAS) and radio frequency identification (RFID) tag (EAS/RFID tag), and includes a detacher (magnet) to selectively disengage a clutch release disposed in a first portion of the combination EAS/RFID tag, a near field circular microstrip antenna configured to electronically read information stored in a second portion of the combination EAS/RFID tag. The antenna encircles the detacher and reads information from the second portion of the combination EAS/RFID tag at a position relative to the detacher when the second portion of the tag is disposed at any angle relative to the detacher and only when the detacher is positioned to disengage the clutch release. As long as the portion of the EAS/RFID tag containing the clutch end mechanism is located over the detaching magnet, the RFID label is in a valid detection zone regardless of its orientation relative to the antenna.
Abstract: The invention relates to an RFID label applicator that may include a peeler body portion having a peel end, the body portion being configured to cause an RFID label to peel away from a web when the web passes around the peel end. The body portion may define a cavity having an RFID programming antenna located therein that is configured to transmit programming signals to the RFID label prior to its passing around the peel end. The system may also include an extendable path altering mechanism configured to advance from a retracted position to an extended position to alter a path of the web around said peel end, and wherein the extendable path altering mechanism is positioned and dimensioned to inhibit a RFID label from peeling away from the web when in the extended position.

Abstract: Methods of operation of a data reader and security tag deactivation system whereby a data reader such as a barcode scanner is equipped with EAS deactivation coils or modules disposed in the vicinity of the read volume or generally proximate thereto and the system is operable to permit reading of the ID tag (such as the barcode label) on an item, and upon a successful read, the deactivation unit is operable to (1) sense the presence of an EAS tag; (2) if presence of an EAS tag is sensed, energize the deactivation coil/module to deactivate the EAS tag; and (3) sense if the EAS tag is deactivated. If the EAS tag is sensed to have been deactivated, the system signals as such and a next item may be scanned. If the EAS tag is sensed to have not been deactivated, the system proceeds to alternate operational steps to handle the exception.
