    摘要: 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.

    摘要: A resonant circuit for use with a radio-wave detection system for the prevention of shoplifting or the like, which is formed on a flexible substrate and has a coil and capacitor circuit whereby the capacitor has an indented area in the dielectric of the capacitor to promote disablement of the circuit when exposed to a strong electromagnetic field. Upon exposure to a strong electromagnetic field, an electrical short forms across the dielectric of capacitor in the indented area. Because the short is fragile and can be opened by flexure of the circuit, an island of reinforcing material is formed in the indented area, such that when the substrate is flexed, the indented area remains rigid to protect the short. The indented area can be further stress-relieved by introducing a gap in the conductors forming the capacitor plates.

    摘要: 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.

    摘要: 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.
