Abstract:
A magnetic decoupling unit that is capable of magnetically releasing several types of magnetically releasable antitheft devices may include a magnet assembly. The magnet assembly may be placed inside a magnet housing with a cover that has an aperture and insert for receiving portions of a magnetically releasable antitheft device. The magnet assembly may include a first magnet with a vertical magnetic orientation which is surrounded by adjacent magnets with magnetic orientations that are orthogonal to the vertical magnetic orientation. Additionally, the magnet assembly includes one or more additional magnets oriented in the vertical and orthogonal directions. The resulting magnet assembly may be capable of magnetically releasing single clutch, double clutch, and electronic media type antitheft devices.

A security tag may include a pin cover, a pin housing, a receiving gap disposed between the pin cover and the pin housing, a pin configured to engage an article placed within the receiving gap, and a biasing member configured to actuate the pin by urging the pin toward the pin cover in response to the article being substantially placed within the receiving gap.
Abstract:
A system for RFID communication includes an antenna device for emitting a wireless signal, and a circuit connected to the antenna device. The antenna device, as a near field antenna, has a dual stripline having a first stripline and a second stripline formed parallel to the first stripline. The antenna device further has a termination, and a balancing element for damping a common mode signal. The balancing element is connected to first connections of the dual stripline, and the termination is connected to second connections of the dual stripline. The circuit is connected to the balancing element for symmetrical emission of the wireless signal to the dual stripline.
Abstract:
A security device may include a lanyard, a lanyard retention lock, and connectivity detection circuitry. The lanyard may include a first conductor and a second conductor that form an open circuit due to an insulator being electrically disposed therebetween. The lanyard retention lock may be configured to retain one or more ends of the lanyard to secure the security device to a protected object. The connectivity detection circuitry may be electrically connected to the first conductor and the second conductor. The connectivity detection circuitry may be configured to detect an occurrence of a closed circuit connection between the first conductor and the second conductor due to, for example, physical damage to the insulator, and may be configured to generate an alarm trigger signal in response to detecting the occurrence of the closed circuit connection between the first conductor and the second conductor.
Abstract:
According to some example embodiments, systems, apparatus, methods, computer readable media, and computer program products are provided for implementing an item pusher apparatus with channel-based shuttle displacement detection, One example method includes determining a position of a channel engagement member affixed to a shuttle, where the shuttle is movable and configured to at least exert a force on an item to urge the item towards a stopping member. The channel engagement member is configured to at least physically interface with as channel defined such that movement of the shuttle alone, to defined movement path causes movement of the channel engagement member in a direction that is nonparallel to the defined movement path in at least one plane. Example systems apparatuses, methods, computer readable media, and computer program products are also provided.
Abstract:
A tag communication method includes providing a tag reader operating at a first frequency and having transmit and receive antenna ports, providing a frequency converter module having transmit and receive plugs adapted to directly mate with the transmit and receive ports, and directly mating the transmit plug with the transmit port and the receive plug with the receive port. A transmit signal at the first frequency is received from the reader by the converter module by way of the directly mated transmit plug and converted to a second frequency differing from the first frequency to provide a converted transmit signal which is transmitted to the tag. A receive signal is received from the tag at the second frequency and converted to the first frequency to provide a converted receive signal which is applied by the conversion module to the reader by way of the directly mated receive plug.
Abstract:
A solid housing tag and method to form the solid housing tag, the method including for example, an injection molding process. The solid housing tag has a single, continuous housing of which at least partially surrounds one or more various tag components arranged about a frame. The tag components may include a lock component and/or security component. The security component may include EAS elements, such as AM, EM, and/or RF technology elements; RFID elements; and/or benefit denial type elements.
Abstract:
A method of making a resonant frequency tag which resonates at a predetermined frequency comprises the steps of forming a first conductive pattern comprising an inductive element and a first land, the first land having a first end connected to one end of the inductive element, and a second end spaced a predetermined distance from the first end; separately forming a second conductive pattern comprising a second land and a link element, the second land having a predetermined width; placing the second conductive pattern proximate to the first conductive pattern at a first predetermined location so that the second land overlies at least a portion of the first land with a dielectric therebetween to establish the plates of a capacitive element with a first predetermined capacitance which with the inductive element forms a resonant circuit; measuring the resonant frequency of the resonant circuit and comparing the measured frequency with the predetermined frequency; if the resonant frequency does not match the predetermined frequency within a selected tolerance, moving the second conductive pattern so that the second land moves along the length of the first land to thereby change the capacitance of the capacitive element; repeating the last two steps until a match occurs; and securing the second conductive pattern to the first conductive pattern.
Abstract:
Apparatus for and method of auditing document numbers from sequentially numbered documents such as business records which includes a scanner for sensing numerics printed on a sales slip or guest check, a memory for receiving and storing a block of numbers associated with a block of such sales slips or guest checks, circuitry for removing from memory a particular guest check number when the guest check is received for payment of the transaction, and a printer for displaying the guest check numbers remaining in memory. In operation, when a block of guest checks which are sequentially numbered have been assigned to the employee of an establishment at the beginning of the business day, the guest checks having the lowest number and the highest number of the assigned block are scanned and the respective numbers printed thereon are stored. The apparatus initiates a count beginning with the lowest number entered and terminating with the highest number entered and stores all of such numbers from the lowest to the highest in the memory. Thereafter, when a guest check is entered into the scanner at a time when payment is received thereon, the number printed on that guest check is removed from memory. Whenever it is desired to determine which guest checks have not been received from the particular block which has been issued, the apparatus can be actuated to provide a print out of the numbers remaining in memory. Also disclosed is a coded member corresponding to a numeric character which has a plurality of pattern portions, one for each half of a horizontal line of a character in a block form, and a pattern portion for an index mark associated with such a character. A scanner is also disclosed for reading such a coded number.
