Abstract:
Embodiments of the invention include delay line circuitry that is integrated with an organic substrate. Organic dielectric material and a plurality of conductive layers form the organic substrate. The delay line circuitry includes a piezoelectric transducer to receive a guided electromagnetic wave signal and to generate an acoustic wave signal to be transmitted with an acoustic transmission medium. An acoustic reflector is communicatively coupled to the acoustic transmission medium. The acoustic reflector receives a plurality of acoustic wave signals from the acoustic transmission medium and reflects acoustic wave signals to the piezoelectric transducer using the acoustic transmission medium. The transducer converts the reflected acoustic signals into electromagnetic waves which are then transmitted back through the antenna and decoded by the reader.
Abstract:
A multi-media reader (MMR) apparatus, secure transaction system and methods thereof are provided. The MMR apparatus includes a slot to receive a card and a near field communication (NFC) antenna to communicate with other NFC enabled devices and cards. The system is provided for securely sharing information over a network to complete one or more transactions using the MMR apparatus and a mobile device. The shared information may be separated and reassembled using on or more servers to increase security.
Abstract:
The present disclosure is directed at systems, methods, and apparatus for precisely inventorying items placed within a user-portable container. The system may comprise one or more interrogators configured to repeatedly send interrogation signals to detect tagged items placed within the portable container by a user. The system may also comprise one or more readers configured to detect response signals produced by the tagged items in response to the repeated interrogation signals. The system may also comprise a communication interface configured to provide information regarding the detected response signals to an adjunct processor configured to analyze the signals and determine whether they originate from items within the user-portable container, as well as to maintain an inventory of items within the portable container.

Abstract:
A dental implant identification system of the non-contact type has a dental implant (260) and a non-contact tip (262) of a reader probe (263). The dental implant (260) has a non-contact RFID tag (264), which is cylindrical in shape, positioned immovably inside an open cylindrical cavity (266) within the main body of the dental implant (260), The non-contact tip (262) of the reader probe (263) includes, at its leading end, a reader antenna coil (268) (which is a transmitter receiver element in the form of a power coil), a coil positioning spring (270) and a reader positioning collar (272). The reader antenna coil (268) is electrically connected to, and receives its power through, wiring (273) from a match circuit (274) along which current flows. In use, the contact tip (262) of the powered on reader probe (263) is inserted through the opening of the cavity (266) of the dental implant (260) until further insertion is prevented by the reader positioning collar (272) becoming wedged ill the opening, and the tag antenna coil (276) and the reader antenna coil (268) are magnetic field coupled. The non-contact RFID tag (264) is passively powered by electromagnetic wave transmissions from the reader antenna coil (268) of the reader probe and received by the tag antenna coil (276).
Abstract:
An underwater antenna assembly (or array thereof) suitable for subsurface RFID tag interrogation in flowing water such as a river. In preferred embodiments, the antenna interrogates RFID tags implanted in aquatic species. The antenna resides in an elongate antenna housing whose cross-sectional shape is preferably a hydrodynamic teardrop shape. A first end of the housing is linked to a pivoting mechanism such that when the pivoting mechanism is held substantially stationary with respect to the water flow, the second end of the housing is free to rotate generally about the first end in a substantially vertical plane parallel to the water flow direction. The length of the antenna housing is advantageously selected to enable the antenna to monitor for signals across substantially the entire water depth.

Abstract:
In accordance with an example embodiment of the present invention, a radio frequency identification (RFID) device comprises a first part (27) having an antenna (27), wherein the antenna is concentrating its radiation power in a main beam propagating in a particular direction (A). The RFID device further comprises a second part (21 ) that is configured to form a body of a portable device and it comprises a transceiver being connected to communicate with the antenna (27). The RFID device further comprises coupling means (25) that is configured to movably couple the first part (27) and the second part (21). The coupling means (25) is configured to move the first part (27) in relation to the second part (21) to the position, in which the antenna is oriented to transmit and receive radio signals to and from a radio frequency identification tag in the direction (A) where the main beam is directed towards the radio frequency identification (RFID) tag.
