In one embodiment, a security includes a planar EAS component having opposing first and second surfaces; and an adhesive layer adhered to the second surface of the planar EAS component and configured to adhere the planar EAS component to an object; wherein the first surface of the planar EAS component comprises a perforation line defining a closed interior portion of the planar EAS component and an exterior portion of the planar EAS component; and wherein the adhesive layer has a strength such that, when the adhesive layer is adhered to the object and the exterior portion is peeled away from the object, the planar EAS component tears along the perforation line and the interior portion remains adhered to the object.

An acoustic magnetic tag includes a housing, a resonant sheet, and a biasing magnetic sheet received in the main body. The housing includes a main body having an opening, a first connecting portion connected to one side of the main body, a second connecting portion connected to an other side of the main body opposite to the one side, a partition connected to the first connecting portion, and a cover connected to the second connecting portion. The partition is rotated relative to the main body to be received in the main body by folding the first connecting portion, and the cover is rotated relative to the main body to cover the opening by folding the second connecting portion. The partition is positioned between the resonant sheet and the biasing magnetic sheet.

A security tag may include a pin cover, a pin housing, a receiving gap disposed between the pin cover and the pin housing, a pin configured to engage an article placed within the receiving gap, and a biasing member configured to actuate the pin by urging the pin toward the pin cover in response to the article being substantially placed within the receiving gap.

A Non-transferable Radio Frequency Identification (RFID) assembly for attachment to an article comprises a RFID module; and a antenna module coupled with the RFID module, the antenna module comprising a conductive layer, a substrate, and an adhesive modification layer between the conductive layer and the substrate, the adhesive modification layer configured such that when the assembly is attached to the article and attempt to remove the assembly will cause the substrate to release and leave the conductive layer intact.

An article, system and method related to a magnetomechanical marker used to mark stationary assets. Magnetomechanical markers can be arranged in clusters and associated with stationary assets, including assets buried underground. Markers can be associated with an asset by being attached to the asset, arranged in a particular spatial relationship with the asset, or in any other appropriate way. A portable locating device can be used to generate an alternating magnetic field to activate the magnetomechanical marker and thus locate the asset.

A perforating gun includes a charge tube having shaped charges affixed thereto. Each shaped charge includes a radially outward pointing post adapted to receive a detonator cord. A retention member installed on the post provides a compressive force that energetically couples the detonator cord to the post. The radially outermost portion of the retention member is radially flush with or radially recessed relative to the radially outermost portion of each post. In one embodiment, the retention member has a rounded medial portion, a central opening and a pair of locking tabs that point radially inward to the central opening. Each post may include a slot for receiving the detonator cord and a circumferential groove that is adapted to receive the locking tabs.

A Non-transferable Radio Frequency Identification (RFID) assembly for attachment to an article comprises a RFID module; and a antenna module coupled with the RFID module, the antenna module comprising a conductive layer, a substrate, and an adhesive modification layer between the conductive layer and the substrate, the adhesive modification layer configured such that when the assembly is attached to the article and attempt to remove the assembly will cause the substrate to release and leave the conductive layer intact.

A wireless communication tape, dispenser of the same and methods of usage of the wireless tape and the dispenser in asset tracking applications are disclosed. The wireless communication tape can be manufactured in an ultrathin form factor by laminating a stack of layers to impart functionality to the wireless communication tape. Methods of use and operation of the wireless communication tape are disclosed to save battery resources of the communication tape.
