Abstract: A small differential-electric-field-activated UHF RFID device. Such a device may be small and easy to manufacture, improving the viability of incorporating RFID technology into articles like tickets, cards, and tokens. Such a device may also be small and inexpensive enough to allow for redundant RFID chips to be placed on an article, improving the survivability of an RFID-enabled article. Such a device may also reduce the amount of metal or plastic that is used in order to create an article such as a smart ticket or card, improving recyclability.

Abstract: A feedback control system for RFID assembly production. The control system can include a measurement system and a control system. The measurement system may take measurements of one or more electrical properties of an RFID chip assembly, for example an RFID strap or RFID antenna. The measurement system may then communicate to the control system to adjust one or more parameters affecting the electrical properties. Once the desired set of electrical properties is achieved, the chip assembly may be cured. The feedback control system may be implemented dynamically, either for precision assembly of individual chip assemblies or in batch for controlling the average properties of assemblies on a rolling production line. The feedback control system can also be implemented in a step-wise fashion and be used to collect data and iteratively self-improve.

Abstract: A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap. The HF coil antenna can include a gap between turns for non-interfering placement of the UHF tuning loop. The EAS circuit can be deactivating upon application of a field at the resonant frequency of sufficient intensity to cause the breakdown voltage to be exceeded between a coil end and coupling area. The threshold breakdown voltage between a coil end and a coupling area can be reduced by laser ablation treatment of a conductive surface of one or both of the coil end or coupling area.

Abstract: Disclosed herein are RFID tags. In one exemplary embodiment, the RFID tag includes an RFID chip; a first antenna segment secured to the RFID chip; a second antenna segment secured to the RFID chip; and a wire segment secured on a first end to the first antenna segment and secured on a second end to the second antenna segment. Generally, the wire segment spans a mounting position of the RFID chip. In one embodiment, the wire segment is secured to the first antenna segment and the second antenna segment with ohmic contacts. The ohmic contacts can be formed by a conductive adhesive, soldering, or welding. In another embodiment, the RFID tag further includes a first non-conductive material positioned between the first end of the wire segment and the first antenna segment, and a second non-conductive material positioned between the second end of the wire segment and the second antenna segment.

Abstract: An RFID device includes a substrate and a lead frame secured to the substrate. The lead frame includes a pair of connection pads formed of a conductive material. An RFID chip and an antenna are electrically coupled to the lead frame. The width of the lead frame is substantially equal to the height of the lead frame. The connection pads of the lead frame may be oriented, among other options, along a direction parallel to a height of the substrate or along a direction parallel to a width of the substrate.

Abstract: An RFID device includes an antenna and an RFID strap. The RFID strap is coupled to the antenna by a combination of magnetic and electric fields. The RFID strap includes an RFID chip and a strap conductor coupling the RFID chip to the antenna. The strap conductor has a loop section positioned generally adjacent to the antenna to magnetically couple the RFID strap to the antenna. The strap conductor also has an extension section overlapping and crossing the antenna to electrically couple the RFID strap to the antenna. By adjusting the size of the RFID strap, the configuration of the RFID strap, the degree of overlap between the extension section and the antenna, and/or the angular orientation of the RFID strap with respect to the antenna, the impedance transformation between the RFID chip and the antenna may be varied to better match the RFID chip and the antenna.

Abstract: A read tunnel device is disclosed for scanning a plurality of cartons of high density packaged items moving through an enclosure via a conveyor belt. The read tunnel device is positioned over a section of the conveyor belt, such that the plurality of cartons on the conveyor belt pass directly through the read tunnel device. Further, the cartons are induced to tumble as they transit through the read tunnel device in one or more dimensions, the tumbling changes arrangement of the items within the cartons and also changes read direction with respect to the antenna in the enclosure. For example, the read tunnel device can comprise a tube angled down from the conveyor belt so a carton will transit down the tube using the force of gravity. Or, a mechanical structure such as mechanical flippers can pick up the carton and rotate it in controlled increments.

Abstract: Methods and systems are provided for testing and/or programming a thread-type string of RFID tags or devices. A thread-type RFID tag is formed on a length or thread having an RFID chip, a first antenna section and a second antenna section, the first and second antenna sections being positioned on the length of thread on opposite sides of the RFID chip. An RFID reader is positioned in electronic communication with a first coupler and a second coupler lying along a path, and the RFID tag and couplers are in relative motion with respect to each other such that the first and second couplers are on opposite sides of the RFID chip. A differential electric field is applied between the first coupler and the second coupler and across the RFID chip whereby the RFID reader couples to the RFID chip and interacts with the RFID tag to carry out testing and/or programming tasks with respect to the RFID tag.
