摘要:
A radio-frequency identification (RFID) tag includes a face stock and an RFID device. The face stock has a printable side and an inlay side, with the RFID device mounted to the inlay side. A layer of adhesive is coated on the inlay side of the face stock. A liner is releasably adhered to the layer of adhesive and includes a relief area that accommodates for defection of the RFID device. The accommodation of the thickness of the RFID device results in a tag that has a substantially uniform printable surface. Accordingly, when passing through a printer, the printable surface is maintained substantially flat or linear at the print head of the printer, thereby minimizing jamming and enhancing printability. A pinch roller for a printer also accommodates for deflection of the RFID tag by providing a deformable section along a length thereof the body that has a greater resiliency than the rest of the body. At the location of the RFID device, the layer of adhesive may also include a blank that is substantially free of adhesive for accommodating the RFID device.

摘要:
A radio frequency identification (“RFID”) antenna structure such as may be found on a tag, label or inlay for use with consumer products that has a conductive surface. The RFID structure of the present invention can be attached to the conductive surface without significantly modifying the performance of the RFID device. The RFID device has first and second portions, with the first portion having a first antenna pattern and the second portion including an elongate section for attachment to the consumer item.
摘要:
A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is bent in alternating sections to form peaks and valleys. The wireless communication device is coupled to the wave antenna to provide wireless communication with other communication devices, such as an interrogation reader. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its bent structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breaks that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly.
摘要:
A label includes a first portion that is printable with optically readable information and a detachable second portion that has an RFID tag that can be encoded with corresponding RFID information. The printable portion and the RFID portion can thus be printed and encoded, respectively, with information for the same container or object. Both portions can then be kept together until the label is ready to be applied. This greatly reduces the chances of applying mismatched optical and RFID labels.

摘要:
A dual mode detection device provides both radio frequency identification and electronic article surveillance functionality. The device includes a dual mode microchip including a logic circuit and a non-volatile memory, the dual mode microchip having an electronic article surveillance (EAS) capability and a radio frequency identification (RFID) capability. An antenna is operatively coupled to the microchip for operation of the RFID capability. A coil is operatively coupled to the microchip and a capacitor is integrated into the microchip such that the coil resonates at a specific frequency, wherein exceeding a breakdown voltage of the capacitor alters a state of a memory location in the non-volatile memory.

An RFID sensing system and method. An array of sensing elements is disposed on a surface of a mat, wherein each sensing element includes an RFID microchip, an antenna operatively coupled to the microchip, and a pressure-sensitive material disposed on at least the antenna. An RFID reader is provided for interrogating the array of sensing elements. An antenna operatively coupled to the reader communicates with each sensing element disposed on the mat. Each sensing element in the array, in response to an interrogation signal, transmits a signal to the reader via the coupled antenna when a subject placed on the mat compresses the section of pressure-sensitive material for the sensing element.
