Abstract:
A combination EAS and UHF security tag that adds the ability to add item level UHF functionality to a retail tag and maintain the integrity of the EAS systems installed in the business and whereby the EAS and UHF security elements are substantially formed from a common conductive layer. This combination tag also includes the ability to change a tag from a "far-field read" tag to a "near-field read" tag.
Abstract:
A security hard tag (20), uses an attachment clip (24) to couple to an article (3), 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 (24) 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 (28) uses a cam (28B), 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 includes a security element and/or a benefit denial. The tag may consist of non-ferrous components only including its locking mechanism.
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:
A re-usable identification tag that includes a combination of RFID (radio frequency identification) elements and EAS (electronic article surveillance) elements, or multiple RFID elements without an EAS element, or multiple EAS elements without RFID elements. Systems and methods for tracking or detecting a re-usable identification tag having multiple elements therein to correspond with multiple detection zones such that as the re-usable tag moves from one detection zone to another, the tag can be tracked and/or activate an alarm and/or transmit data to a database.
Abstract:
Security labels and tags (100) including elements and methods of making them are disclosed. The elements are in the form of an oriented polymer layer (14), conductive traces (12, 16) clad to the polymer layer to form an open loop (24) forming a window (w) in the interior of the loop and an open support framework (102a - 102g) extending into the window to support the polymer layer in the window. In some embodiments the open support framework is in the form of parallel, interleaved linear extensions from the conductive traces which extend into the window. In other embodiments the open support framework is in a pattern of intersecting sections (e.g., a fishbone pattern) located in the window.

A three-dimensional dipole antenna system or an RFID tag that optimizes detection for a given available volume in which to situate the RFID tag
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 multi-attach reusable security tag (MARST) that is attached to an article in two stages, hx a first stage, an attachment clip is coupled to an article, such as but not limited to clothing, to be protected by a manufactxirer 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, the attachment clip is then secured in a reJeasable locking mechanism of a housing containing a security element, therein. The security element may comprise HAS (including AM, RF, EM and microwave), !IFID (including LF, ITf and UHF) elements or any combination thereof. Alternatively, a fluke element can be used to secure the attachment clip to the reJeasable locking mechanism and wherein this fluke element permits the attachment clip to swivel outside of the housing. 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, visuaily-deterring, and installable in two stages to the article it is meant to protect.
Abstract:
A multi - attach disposable security tag is attached to an article in two stages. In a first stage, an attachment clip is coupled to an article by an article manufacturer or assembler. This attachment clip is durable to withstand harsh manufacturing environments. During a second stage, the attachment clip is then permanently secured in a locking mechanism of a housing (604) containing a deactivatable security element for article presentation at a retail establishment. The attachment clip may be rotatable or non - rotatable with respect to the tag housing (604). 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. 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.
