Abstract:
A security hard tag, uses an attachment clip to couple to an article, such as but not limited to clothing, to be protected and which can only be released from the article by use of an authorized detacher that is inserted into the security hard tag. The attachment clip may include various types of locking mechanisms on its two ends, one end which is permanently secured within the security hard tag housing and the other end which is releasably secured within the housing. Before being releasably secured within the housing, the one end is inserted through or around a portion of an article, or through a security tag loop attached to the article, and then that end is locked into the housing. The detacher uses a cam, either located on the detacher itself or positioned within the security hard tag housing, to interact with the one end of the attachment clip to release the locked end. The housing also includes a security element that may comprise EAS (including AM, RF, EM and microwave), RFID (including LF, HF and UHF), benefit denial (e.g., ink-filled or dye-filled capsules) or any combination thereof. A preferred embodiment of the security hard tag uses all non-ferrous components including its locking mechanism. The non-ferrous composition of the security hard tag, along with the attachment clip design, forms a security hard tag that is strong and lightweight, thereby providing a low impact presentation of a security hard tag with an article.
Abstract:
A microwave-resistant and waterproof security tag for use with food products, especially meat products. The security tag includes a pair of single, open loop conductive traces in between which is disposed a similarly-shaped dielectric layer. This combination is encapsulated within plastic membranes or covers that are sealed at their common edges. The preferred embodiment includes rectangularly-shaped single, open loop conductive traces with rounded corners and with one end of each trace forming a capacitor plate. The width of each trace is at least 1/10 of the length of the security tag.

Abstract:
The present invention is directed towards a novel procedure and system for making a security tag for an aluminum-pressed, cardboard container. The method employs a system of distancing the tag from the container and a method of calibrating the tag. The tag is then inserted into a specially designed cap and spaced a given distance from the container. The product is sealed and then sold to the consumer.
Abstract:
A tag and method of making it. The tag includes a first adhesive layer provided in a first predetermined pattern between a surface of a first substrate and a first conductive foil. The first pattern corresponds to a pattern for a first conductive trace, e.g., a portion of a resonant circuit. The first conductive foil is laminated, e.g., adhesively secured, to the surface of the first substrate to form a first conductive layer. A first portion of that layer is shaped, e.g., die-cut, to generally correspond to the first pattern. A second portion of the first conductive layer not corresponding to the first portion is removed, to establish the first conductive trace, with the adhesive layer confined within the boundaries of the first conductive trace. Another conductive trace is secured to the first conductive trace, with a dielectric therebetween, to form a resonant circuit.
Abstract:
A security tag that is attached to an article in two stages. In a first stage, a first portion of an attachment clip is coupled to an article, such as but not limited to clothing, to be protected by a manufacturer or assembler. This attachment clip is durable to withstand harsh manufacturing environments. Once the article with the attachment clip is ready for presentation, for example, at a retail establishment, during a second stage, a second portion of the attachment clip is then permanently secured in a locking mechanism of a housing containing a security element therein. The security element may comprise EAS (including AM, RF, EM and microwave), RFID (including LF, HF and UHF), benefit denial (e.g., ink-filled or dye-filled capsules) elements or any combination thereof. Because the security tag is not removed from the article at the point-of-sale, the security element is deactivatable. A preferred embodiment of the security tag uses all non-ferrous components including its locking mechanism. Thus, the security tag combines the qualities of being non-ferrous, light-weight, low cost, deactivatable, secure, visually-deterring, and installable in two stages to the article it is meant to protect.
Abstract:
A resonant circuit for use with a radio-wave detection system for the prevention of shoplifting or the like which has a coil and capacitor circuit whereby the circuit is permanently destroyed when the tag is exposed to a radio signal that causes a voltage across the capacitor that exceeds the breakdown voltage of the capacitor. The capacitor comprises a dielectric that does not exhibit self-healing. Such dielectrics include ceramics, metal oxides and minerals.
Abstract:
A security tag includes a combination of a resonant frequency circuit with an adjacent amplification shield for enhancing output signal amplitude. The amplification shield is located adjacent to the resonant frequency circuit and is preferably in the same or substantially the same plane as the resonant frequency circuit or is in a close, generally parallel plane. In an exemplary embodiment, the resonant frequency circuit includes an inductor electrically coupled to a capacitor. The resonant frequency circuit has a center frequency and is arranged to resonate in response to exposure to electromagnetic energy at or near the center frequency, providing an output signal having an amplitude. The amplification shield is arranged to direct a portion of the electromagnetic energy to the resonant frequency circuit to amplify the amplitude of the output signal from the resonant frequency circuit.
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.

The security element may comprise EAS (including AM, RF, EM and microwave), RFID (including LF, HF and UHF) elements or any combination thereof. A preferred embodiment of the security tag uses all non-ferrous components including its locking mechanism. Thus, the security tags combine the qualities of being non-ferrous, light-weight, low cost, deactivatable, secure, visually-deterring, and installable in two stages to the article it is meant to protect.
