Abstract: An inventory monitoring system and process for monitoring inventory is shown and described herein. The system and process includes an RFID reader configured to collect or receive product code data, location data, and secondary metric data of inventory RFID tags relative to that of other RFID tags or markers for determining the location of the inventory from such data. From the information obtained from the RFID tags, the location of inventory in an environment can be determined.

Abstract: A dual security tag including an RFID component and an electronic article surveillance (EAS) component, respectively disposed on opposite sides of a PET carrier substrate, is provided. The RFID component may include one or more ultra-high frequency antennae, such as a near field loop antenna and a far field dipole antenna, and an integrated circuit (IC) chip. The EAS component may be provided as an RF device, an acoustic-magnetic (AM) device, a low power Bluetooth (BLE) device, or other suitable device. The security tag may also include a facesheet affixed to the RFID component, a release liner layer affixed to the EAS device, and one or more intermediary films or protective layers. A method for manufacturing a dual security tag is also described.

Abstract: The present invention provides for an RFID transponder, suitable for use in a wristband, which has a non-uniform loop that provides a staple RF environment between the wrist and the transponder; a tuning capacitor for minimizing the overall transponder link; a single transmission line for fine tunings; and an asymmetric location of the RFID IC and capacitor for accommodating needs for specified “keep out” areas for packaging.

Abstract: A RFID system that includes a RFID user input device and an RFID-enabled device. The user input device is configured to send one or more commands to control the enabled device. The user input device may include an antenna pattern operatively connected to one or more separate integrated circuits. The user input device may further include an input component associated with each integrated circuit. The input components may be activated causing information stored at the associated integrated circuit to be sent to the enabled device. The enabled device may be configured to act upon the information in a desired manner.

Abstract: An identification system for machinery or equipment, such as an aircraft engine, includes a name plate, a mounting bracket for mounting the name plate, a housing, and an RFID tag positioned within the housing between the name plate and the mounting bracket. The RFID tag includes an integrated circuit and an antenna such as a patch antenna.

Abstract: A Radio Frequency Identification (RFID) device can comprise a dielectric separator and a RFID antenna with a RFID chip region. The antenna can have a main section and at least two tuning stubs that fold back from areas on the main section of the RFID antenna which are away from the RFID chip connection region back towards the RFID chip antenna region. The tuning stubs can be spaced away from the main section.

Abstract: An RFID tag system includes a housing that includes an enclosed sidewall and forms a recess with a housing base surface, where the housing is configured and arranged to be mounted to a mounting surface. An RFID tag is located within the housing, and the RFID tag comprises an integrated circuit, an antenna and a metal backplane, where the housing base surface separates the antenna and the metal backplane. A metal surface is secured to a top surface of the sidewall to cover the recess, where the metal surface and a transmission path from the integrated circuit to the antenna are electromagnetically coupled and tuned to operate across a wide band frequency range. The metal surface may include a name plate of a data plate for a gas turbine engine, or a component thereof.

Abstract: A radio frequency identification (RIFD) inlay includes an electrical connection between a chip and an antenna. The electrical connection includes conductive interposer leads and a capacitive connection. The capacitive connection may involve putting the antenna and the interposer leads into close proximity, with dielectric pads therebetween, to allow capacitive coupling between the antenna and the interposer leads. The dielectric pads may include a non-conductive adhesive and a high dielectric material, such as a titanium oxide. The connections provide a convenient, fast, and effective way to operatively couple antennas and interposers. The RFID inlay may be part of an RFID label or RFID tag.

Abstract: A method of aircraft maintenance involves storing part information relating to an aircraft part on the aircraft part. The part information is wirelessly transmitting from the aircraft part to a receiver. A note of a change relating to the aircraft part is made. The part information with the note of the change relating to the aircraft part is electronically stored at a location remote from the aircraft part.

Abstract: A tool tray can comprise a body with tool shaped recesses. A Radio Frequency Identification (RFID) tag can be positioned in one of the recesses. The RFID tag can be such that when no tool is placed in the one of the recesses, the tag is not detectable at a reading distance; but, when a corresponding tool is placed into the one of the recesses, the RFID tag is detectable from a reading distance.

Abstract: An RFID antenna can include a shunt across a connector region of a length in a range of 1/6 to 1/3 of the operating wavelength of the RFID antenna. This can improve the operating characteristics of the RFID antenna.

Abstract: A radio frequency identification (RIFD) inlay includes an interposer that has a chip, and an antenna on an antenna substrate. The antenna substrate has a recess or hole, and the chip is at least partially in the recess or hole. By placing the chip or the interposer face down and at least partially in a recess or hole, thickness of the inlay may be reduced.
