摘要： A reflective communication system allows information from wireless communication devices, such as radio-frequency identification devices (RFID), to be reflectively communicated to a receiver. A transmitter at a known location transmits a communication signal to the wireless communication device. The wireless communication device modulates a data signal onto the communication signal to form a reflected data signal and reflects the reflected data signal to the receiver. The receiver receives the communication signal from the transmitter and can determine a distance between the wireless communication device and the transmitter based on data that includes a time delay between receipt of the communication signal and receipt of the reflected data signal by the receiver. The receiver can further determine the approximate location of the wireless communication device based on data that includes the known location of the transmitter and the determined distance between the wireless communication device and the transmitter.

摘要： A method of producing antennas for RFID devices includes cutting or otherwise physically separating the antennas from a preformed sheet of conductive material that includes apertures in the conductive material. Cutting locations relative to the apertures may be selected based on desired performance characteristics of the antenna and/or of the RFID device for which the antenna is to be used. The cutting locations may include one or more cuts through the aperture, and other cuts that do not pass through an aperture. The cutting locations may be selected as a function of such parameters as the desired bandwidth of the antenna and the operating frequency of the antenna. The method allows production of antennas with different characteristics, from a previously-prepared supply of sheet conductive material. This facilitates the ability to make small production runs of antennas, and/or to reduce the lead time for providing antennas with specified characteristics.

摘要： An RFID label includes a release liner having an opening or window, to allow placement of an interposer through the window, and in contact with end portions of an antenna. By coupling the interposer to the antenna through the window in the release liner, the coupling may be performed at a later point than usual in the fabrication of the label. This allows the label to be fabricated with less wear and tear on the interposer, which is a relatively expensive and fragile part of the antenna. In addition, testing of the interposers before applying them to a web of labels may save costs by eliminating waste of material. Testing of the straps alone can allow prediction of performance of the finished label.

摘要： A radio frequency identification (RFID) system includes a portable RFID reader, and a read infrastructure that includes a distributed read structure, which may be part of a display (such as a shelf) for holding objects. The read structure is used to couple the RFID reader to RFID devices (tabs and/or labels) on or near the structure. The RFID reader and the read structure communicate in a near field or proximity region communication, without any use of a direct ohmic electrical connection. The RFID reader may have an antenna that is configured for near field or proximity communication with a coupler of the read infrastructure. The RFID reader may also have a separate antenna for use in far field communication. The RFID reader may be able to obtain information more efficiently in the near field or proximity mode, allowing information to be received faster and with greater reliability.

摘要： A radio frequency identification (RFID) device has multiple modes of operation. One of the modes of operation is an electronic article surveillance (EAS) mode, which is used to allow use of the RFID device as an EAS device. Another mode of operation is an RFID mode, which allows normal function of the RFID device in RFID communications. The EAS mode has greater sensitivity than the RFID mode, requires less power than the RFID mode to operate the device, and requires less current and/or voltage for operation. The EAS mode may achieve these different characteristics by one or more of: switching off some digital blocks in the circuitry of the RFID device; reducing power storage required to respond to incoming signals; reducing the length of response to incoming signals; reducing modulation required for a response; changing chip input impedance; and having multiple chip ports with different impedances.

摘要： An RFID device includes a chip, an antenna operatively coupled to the chip, and a visual indicator operatively coupled to the chip. The visual indicator provides a visual indication of an operative state of the device. The visual indication may be human readable and/or machine readable, and may provide visual indication that is dependent on a change in an operative state of the device. The operative state that triggers the visual indication may include a state in which the chip has temporarily or permanently been rendered inoperative or disabled, that is, in which the chip no longer responds to, or otherwise interacts with, ordinary incoming RF signals such as from a device reader. The visual indicator may be included in a display that functions by any of a variety of suitable mechanisms, such as by use of electrochromic materials, thermochromic materials, liquid crystals, or chemically-reactive materials.

摘要： An RFID device includes an antenna structure that provides good performance throughout a range of different positions relative to nearby materials, such as metallic objects in a carton or other container. The antenna structure has compensation elements that interact with the nearby materials to provide good performance over the range of different positions. The compensation elements include both electrical compensation elements, which interact with the nearby materials primarily using electric fields, and magnetic compensation elements, which interact with the nearby materials primarily using magnetic fields. The electrical compensation elements and the magnetic compensation elements may be selected and may be positioned within the antenna structure such that the performance of the antenna structure is substantially unchanged (or at least acceptable) through the range of different positions.

摘要： An RFID device preparation system includes a printer combined with a short-range tester/reader. The tester/reader operatively couples to the RFID device using capacitive and/or magnetic coupling. By use of capacitive and/or magnetic coupling, good read characteristics may be obtained, while obtaining excellent discrimination between various RFID devices that may be in or near the tester/reader. Thus, RFID devices may be inexpensively and reliably tested one at a time, without appreciable interference or effect due to the presence of other RFID devices. The tester/reader may include electric-field and/or magnetic-field coupling elements that are configured to receive different signals, in order to test a variety of configurations of RFID devices. This may enable the device preparation system to accommodate various types and configurations of RFID devices, increasing versatility of the system.
