Miniaturization of radio frequency integrated circuits has made attaching these circuits to their antennas increasingly difficult and costly. This invention uses magnetic coupling, as performed in transformers, between circuits and antennas as a practical solution to reduce cost and effort in attaching the two sides as well as to protect the circuit against electrostatic discharge. Furthermore a simple pre-assembly testing methodology is accounted for as an additional benefit of the method.Type: GrantFiled: April 21, 2008Date of Patent: April 29, 2014Assignee: Tagarray, Inc.Inventors: Kourosh Pahlavan, Mohammad Amin Arbabian

Publication number: 20140111338Abstract: Method for reducing undesired alarms in an electronic article surveillance (EAS) system involves measuring a tag response at a first and second pedestal to obtain contemporaneous first and second tag responses. The tag responses are compared to evaluate relative signal strength and thereby discern a lesser signal strength tag response. A reduced level exciter drive signal is applied to a selected one of the first and second pedestals associated with the lesser signal strength tag response. A detection zone is then monitored to determine the occurrence of a third tag response resulting from the reduced level exciter signal. The approximate location of the tag in relation to the first and second pedestals is determined based on the first, second, and third tag responses.Type: ApplicationFiled: May 17, 2013Publication date: April 24, 2014Applicant: Tyco Fire & Security GmbHInventors: ADAM S.

Patent number: 8704642Abstract: The present invention relates to an RFID-based intelligent storage cabinet and its management method, while utilizing the shielding effect enabled by each partitions for allowing any electromagnetic wave in one compartment to transmit only inside the confinement of such compartment without interfering another compartment. Each stock keeping unit (SKU) that is to be stored in the RFID-based intelligent storage cabinet is attached with at least one RFID tag, and different SKUs of different usages are sorted so as to be stored in different compartments. Moreover, each RFID reader can be designed to function according to the command of a control device for scanning the corresponding compartment in a periodic manner or non-periodic manner, by that any SKU that is stored in the corresponding compartment can be detected and identified as each RFID reader is also connected to an inventory database, a database of item list, or a memory database.Type: GrantFiled: September 23, 2011Date of Patent: April 22, 2014Assignee: Claridy Solutions, Inc.Inventor: Horng-Ji Chen

Patent number: 8706050Abstract: There are provided a matching circuit which is less prone to impedance mismatch even with variations in pattern dimension, and a wiring board, and also a transmitter, a receiver, a transceiver, and a radar apparatus that succeed in offering stable characteristics with the installation of the matching circuit. Characteristic impedance of a first transmission line including a connection portion is varied between a reflection source including a stub portion and a bonding wire serving as a load. Impedance variation is achieved by varying a distance from the connection portion to a back conductor layer coupled thereto with respect to a distance from the stub portion and a transmission line portion to an inner conductor layer coupled to them.Type: GrantFiled: July 31, 2009Date of Patent: April 22, 2014Assignee: Kyocera CorporationInventor: Nobuki Hiramatsu

Patent number: 8698697Abstract: In a semiconductor device in which a copper plating layer is used for a conductor of an antenna and in which an integrated circuit and the antenna are formed over the same substrate, an object is to prevent an adverse effect on electrical characteristics of a circuit element due to diffusion of copper, as well as to provide a copper plating layer with favorable adhesiveness. Another object is to prevent a defect in the semiconductor device that stems from poor connection between the antenna and the integrated circuit, in the semiconductor device in which the integrated circuit and the antenna are formed over the same substrate. In the semiconductor device, a copper plating layer is used for the antenna, an alloy of Ag, Pd, and Cu is used for a seed layer thereof, and TiN or Ti is used for a barrier layer.Type: GrantFiled: June 9, 2008Date of Patent: April 15, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Teruyuki Fujii, Kazuya Hanaoka

Patent number: 8695243Abstract: The secure license plate holder is specific to the vehicle to which it is assigned, having the vehicle identification number (VIN) permanently disposed on the holder. The holder is secured with tamperproof security fasteners requiring specialized tools for installation and removal. The license plate is also secured to the holder with tamperproof security fasteners. Decorative covers are installed over the fastener heads to prevent misinterpretation of the head as a part of the alphanumeric characters on the license plate and to indicate tampering. The holder includes an embedded SIM (subscriber identity module) chip, and the vehicle has a corresponding chip installed therein. Thus, removal of the plate and holder requires removal of part of the vehicle structure in order to avoid obvious damage to the fasteners and their covers.Type: GrantFiled: May 28, 2013Date of Patent: April 15, 2014Inventor: Farraj J.
