Abstract: A system for locating a RFID tag in a space or area having a physical barrier is disclosed herein. More specifically, the system comprises a plurality of guard tags for use in conjunction with a RFID tag disposed on an item and a RFID reader for locating the same. The system is configured to locate the RFID tag on either side of the physical barrier. The plurality of guard tags may comprise a plurality of negative encoded guard tags and a plurality of positive encoded guard tags, and an algorithm may be used to determine a probability of the RFID tag location within the physical space. A method of locating a RFID tag within a physical space, and a method of virtually shielding the physical space is also disclosed.

Abstract: A RFID label for use on a lid of a container, and a method of using the RFID label. The RFID label comprises a substrate component, a RFID antenna formed on the substrate component, and a RFID chip for storing data coupled to the RFID antenna. The RFID label is positioned or configured on the lid so as to limit or avoid any interference between the RFID antenna and the RFID chip by any metal component of the container. The RFID label is particularly useful for containers that have small lids or metal components, such as vials, where conventional RFID usage is limited.

Abstract: A radio frequency identification (RFID) tag with a configurable anti-tamper structure includes an RFID chip electrically connected to a configurable anti-tamper structure. The configurable anti-tamper structure includes a plurality of conductive segments substantially oriented in a ladder configuration. At least some of the plurality of conductive segments are cut to leave a single conductive path in accordance to the desired tamper detection application, and the RFID tag is attached with the anti-tamper structure placed across a break point to be monitored for tampering. When tampering occurs, the conductive path is broken and the RFID chip changes the data sent in response to interrogation by an RFID reader.

Abstract: Radio frequency identification (RFID) systems for use with tires include a stud comprising reactive strap technology including an RFID chip and conductor. The stud is configured so as to be connected to a tire and to provide near field communication. The stud also may be coupled to an antenna structure to provide a far field RFID tag. The stud may unintentionally move with respect to the antenna structure during use, so the antenna structure may be configured to accommodate such movement without a change in the tuning of the RFID tag. A multi-antenna label may be provided to allow for selective coupling of the stud to a particular antenna, with differently configured tires being coupled to different antennas of the same type of multi-antenna label, which allows for the same label configuration to be used with a wider variety of tires.

Abstract: A label stack assembly and method and system for preparing the label stack assembly is disclosed herein. The label stack assembly may be applied to a product in order to provide care instructions in multiple different languages. Individual pages of the label stack assembly may have separate content, such as translations of care instructions into multiple languages, and may be marked by tabs of various shapes, sizes, or styles that may protrude from an edge of the label stack assembly. Tabs may be marked with country codes indicating the translations or other information. The pages of the label stack assembly may be printed on both a front and a back side, such as may be desired, in order to minimize the number of pages used while maximizing the number of care instruction translations or other content pages.

Abstract: Systems and methods are provided for creating printed tags for use in connection with a heated food item placed into a hot holding unit. System components may include a user interface, a printer, and a controller. The controller is programmed to instruct the user interface to display a prompt for an operator to input information identifying one or more characteristics of a food item positioned within or to be placed into a hot holding unit. The controller receives the information from the user interface and instructs the printer to generate a tag identifying the food item and the time at which the food item is to be removed from the hot holding unit and discarded. The tag may include a display area to display the printed information and a support area with a slit that allows the tag to be supported by a rack of the hot holding unit.

Abstract: Improved RFID devices and manufacturing methods that utilize more efficient RFID designs, result in less manufacturing material waste and increased recycling opportunities, all without sacrificing RFID device performance, are disclosed herein. Some exemplary embodiments of the improved RFID device may make use of a thinner foil, a hollowed-out foil, a “no-strip” design, or a tessellated design that may reduce material usage. Other exemplary embodiments may use a lower-impact and/or biodegradable adhesive so as to improve aluminum recycling and lessen risks to the environment.

Abstract: The antenna of an RFID device is formed by applying an adhesive to a substrate. A conductor is secured to the substrate using the adhesive and then a gap is defined in the conductor in the shape of an antenna so as to isolate an inner region of the conductor from an outer region of the conductor. Heat is applied to the outer region of the conductor so as to cause at least a portion of the adhesive positioned between the outer region of the conductor and the substrate to undergo a phase change or be activated without causing at least a portion of the adhesive positioned between the inner region of the conductor and the substrate to undergo a phase change or be activated. The outer region of the conductor is then dissociated from the substrate, with the inner region of the conductor remaining secured to the substrate by the adhesive as an antenna.
