Abstract:
An antenna assembly is capable of being installed in a structure wherein the structure includes a covering and a substructure and the antenna assembly is configured with thin film materials to have a total thickness such that the antenna assembly can be disposed between the substructure and the covering. The antenna assembly may have a total thickness not greater than about 15 millimeters (mm), and may include at least one of a transmitter antenna, a transceiver antenna, and a receiver antenna. The receiver antenna may be configured as an air core antenna or a non-air core antenna. The receiver antenna may be configured as a non-air core receiver antenna in an internal compartment over or within a base insulating layer. The antenna assembly may be at least partially housed within a housing assembly of thin film materials so that both can be disposed between the substructure and the covering.

Abstract:
An electronic article surveillance antenna system with wide interrogation zones has a number of core transceiver antennas with each connectable to a transmitter. The core transceiver antennas are adapted to be installed adjacent a ceiling of the wide interrogation zone and generate an interrogation signal into the wide interrogation zone. The core transceiver antennas each are connectable to a receiver to receive and detect a response signal from an electronic surveillance marker disposed in the wide interrogation zone. The system also has transceiver antenna coils with each connectable to the transmitter and adapted to be installed adjacent a floor of the wide interrogation zone. The transceiver antenna coils generate the interrogation signal into the wide interrogation zone and each is also connectable to the receiver to receive and detect the response signal from the electronic surveillance marker disposed in the wide interrogation zone.
Abstract:
An EAS/expulsion detrimental substance tag in which the tag is held to an article by an attaching assembly, a part of which may be releasably prevented from being withdrawn from the body of the tag. The tag body may be provided with an arcuate channel through which an arcuate detacher probe can be guided for releasing the attaching assembly part. A spring clamp may provide the releasable preventing function and may include jaws specifically adapted to respond to in-plane torsional and/or other forces provided by the arcuate probe, which may be moved through the arcuate channel by rotation to reach the spring clamp. An abutment may be placed within the arcuate channel to prevent a relatively rigid wire formed into an arcuate shape from being used to release the attaching assembly part. The Benefit Denial (Ink portion) of this tag may feature an ink vial that may be disposed inside of a rubber bladder, which may then be placed in a completely sealed, ultrasonically welded compartment. In one embodiment, when the tag and its ink vial are attacked, the tag will expel the detrimental substance out and onto the article being protected. In another embodiment, when the tag is attacked, the detrimental substance may be forced out of the bladder and then into a channel and then out a hole in the rampart area and may stain the article that is being protected.
