Abstract: RFID devices for use in electronic surveillance article (“EAS”) systems may be differently configured, resulting in different performance at the operating frequency or range of frequencies of an EAS system. The performance of differently configured RFID devices may be converged or rendered substantially similar by testing the performance of such RFID devices in a range of frequencies. At least one of the RFID devices is reconfigured to converge the performance of the RFID devices in the range of frequencies if the performance of the RFID devices is not sufficiently similar. This may include changing the configuration of an antenna, an RFID chip, and/or a non-functional component of an RFID device and/or the location in which an RFID device is associated to an article. Differently configured RFID devices may all be manufactured from the same initial configuration, with different RFID devices being differently processed before incorporation in an EAS system.

Abstract: A method of detection of unauthorized intervention into an identification structure is provided. The method includes configuring the identification structure such that the identification structure interacts with the intervention such as a physical intervention, or mechanical intervention, or electrical intervention. Further, the method involves propagating the intervention along the identification structure in such a control as to cause a detectable alteration in any predetermined attributes associated with the identification structure including a physical attribute, mechanical attribute, electrical attribute, and an optical attribute. Finally, the alteration in the attributes is detected by visual, electrical, or optical assessments or a combination of assessments.

Abstract: Compositions and methods to produce adhesive articles with active agents concentrated at the substrate contacting surface. The active agents are applied in powder form, or in combination with a liquid or gel vehicle, to the substrate contacting surface of an adhesive layer of an adhesive article. The active agent compositions are directly applied to the adhesive layer, or are first applied to a release liner, which is then brought into contact with the adhesive layer to dispose the active agent compositions to the substrate contacting surface of the adhesive layer. Upon application of the adhesive article to a substrate, the active agent is delivered to a region of interest on the substrate.

Abstract: A temperature-sensing RFID device includes an RFID chip and an antenna electrically coupled thereto. The RFID chip includes a temperature sensor, while the antenna is adapted to receive energy from an RF field and produce a signal. A shielding structure and/or a thermally conductive or absorbent structure may be associated with the RFID chip. The shielding structure is oriented so as to be positioned between at least a portion of the RFID chip and an outside environment and configured to shield the temperature sensor from at least one environmental factor capable of affecting a temperature sensed by the temperature sensor of an article to which the RFID device is secured. The thermally conductive or absorbent structure is oriented so as to be positioned between at least a portion of the RFID chip and the article and configured to enhance thermal coupling between the temperature sensor and the article.

The first and second openings together may define a passage through both the conductor and the flexible backing material.

Abstract: Provided herein are multilayer tape constructions comprising a damping layer and a bonding layer, wherein the multilayer tape construction effectively dissipates vibrations at low temperatures. The materials and configurations of the layers are selected such that the glass transition temperature of the bonding layer is greater than the glass transition of the damping layer, and the difference between the glass transition temperatures is related to the relative thicknesses of the damping layer and the bonding layer. The multilayer tape constructions may further comprise a carrier layer. Also provided are systems and methods using the disclosed multilayer tape constructions.

Abstract: A method, system, and apparatus for inserting a woven label with integrated radio frequency identification (RFID) capabilities into a garment seam is shown and described. In exemplary embodiments, a woven RFID label is inserted into a garment seam during stitching.
