    摘要: A security tag used with an electronic article surveillance system for detecting the presence of the tag within a surveilled area utilizing electromagnetic energy at a frequency within a predetermined detection frequency range includes a dielectric substrate having first and second opposing principle surfaces, a peripheral outer edge, and a resonant circuit capable of resonating at a frequency within the predetermined detection frequency range. The security tag also includes a guard member, in one embodiment a discontinuous conductive member, effectively electrically isolated from the resonant circuit, extending along at least a portion of the peripheral outer edge of the substrate for surrounding at least a portion of the resonant circuit. The guard member electrically isolates the resonant circuit to facilitate testing of the resonant circuit during an early stage of the manufacturing process when the resonant circuit is in web form.

    摘要: A security tag for use with an electronic security system which functions within a second frequency range comprises a substantially planar dielectric substrate having first and second sides. A first conductive pattern is provided on the first side of the substrate, the first conductive pattern comprising at least a first inductive element, a first plate of a first capacitive element and a first plate of a second capacitive element. A second conductive pattern located on the second side of the substrate comprises at least a second inductive element, a second plate of the first capacitive element and a second plate of a second capacitive element with the plates of the capacitive elements being generally aligned. The inductive elements and the capacitive elements form a resonant circuit which resonates at a first frequency within a first frequency range which is outside of the second frequency range. A direct electrical connection extends through the substrate to electrically connect the first conductive pattern to the second conductive pattern to thereby continuously maintain both sides of the substrate at substantially same static charge level.

    摘要: A resonant tag used with an electronic article surveillance system for detecting the presence of the tag within a surveilled area utilizing electromagnetic energy at a frequency within a predetermined detection frequency range includes a resonant circuit capable of resonating at a frequency within the predetermined detection frequency range. The resonant circuit includes an inductor formed at least in part on a surface of a dielectric substrate of the tag. The inductor is formed with a discontinuity or gap, causing an electrical open circuit. The open circuit is closed with a fuse secured proximate to the gap and wirebonded to the portions of the inductor proximate to the gap. The fuse is melted by a current greater than a predetermined level flowing therethrough. Such a high current may be induced in the inductor by an external electromagnetic field. Melting of the fuse causes an open circuit condition, which alters the frequency at which the tag resonates.

    摘要: 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.

    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.
