  • Patent number: 10305606
    Abstract: Communication between a wireless base-station and a microwave reflector link are enhanced by feeding back a portion of the transmitter signal, adjusted for phase and amplitude, to cancel ambient reflection blocker signals being received at the base-station. The microwave reflector link does not utilize a transmitter gain stage, but communicates data back to the base-station in response to modulating the reflections of its antenna (e.g., in gain and/or phase). The disclosure aids in the proper amplification and processing of reflection signals from the microwave reflector link, by canceling out the blocking signals which arise as background objects reflect transmitter signal energy back to the base-station.

  • Patent number: 10297914
    Abstract: An apparatus and method for enhancing full-duplex radio communications using an indented transmitter and receiver antenna. A multi-element antenna array is configured with each antenna coupled to a circulator that has connections to both a transmission path and a receiving path. The apparatus is configured with indentations that provide a tilting of the array from its broadside to create a progressive phase delay between adjacent pairs of elements. Transmitted and received waves travel a single trip through the indention, while antenna reflection or circulator leakage travels a round trip through indention, so that these signal components can be readily separated to achieve high levels of isolation during full-duplex transmitting and receiving.

  • Patent number: 10256672
    Abstract: A first power receiving apparatus observes a power transfer signal from a power supply apparatus, and detects whether power transfer is being performed between the power supply apparatus and a second power receiving apparatus. When the power transfer is being performed between the power supply apparatus and the second power receiving apparatus, a waveform of the signal is deformed with a predetermined pattern. The second power receiving apparatus detects deterioration in power which is received from the power supply apparatus and detects whether the waveform of the signal changes with the predetermined pattern within a predetermined time after detecting the power deterioration. When detecting the change in the waveform of the signal with the predetermined pattern, the second power receiving apparatus determines that the first power receiving apparatus is in a power suppliable range of the power supply apparatus.

  • Patent number: 9941934
    Abstract: In a general aspect, a method can include producing, by an inductive antenna circuit, a first periodic signal that is based on an alternating external magnetic field; producing, by an oscillator circuit, a second periodic signal that is based on the first periodic signal; and transmitting, in correspondence with a data-carrying modulation signal, a sequence of data bits. The transmitting can include sequentially and repetitively: applying, with the oscillator circuit operating in a free oscillation mode, the second periodic signal to the inductive antenna circuit; and inhibiting, with the oscillator circuit operating in a synchronous oscillation mode, application of the second periodic signal to the inductive antenna circuit. The synchronous oscillation mode of the oscillator circuit can cause the second periodic signal to be synchronized to the first periodic signal.

  • Patent number: 9911020
    Abstract: Aspects of the subject disclosure may include, for example, a device, including a radio frequency interface configured to receive, from a radio frequency identification device, a first wireless signal of a first carrier frequency that indicates a personal identifier. A transceiver can be configured to generate a transmission signal of second carrier frequency that indicates the personal identifier and location information associated with the device and to transmit electromagnetic waves in response to the transmission signal at a first physical interface of a transmission medium that propagate without requiring an electrical return path. The electromagnetic waves are guided by the transmission medium and are received by a receiving device at a second physical interface of the transmission medium, and the transmission signal can be extracted from the electromagnetic waves by the receiving device. Other embodiments are disclosed.

  • Patent number: 9872141
    Abstract: A method includes moving an interrogation device through multiple geographical positions. At each geographical position of the interrogation device, a wireless communication terminal is solicited to establish temporary communication with the interrogation device, and a value indicative of a distance between the wireless communication terminal and the interrogation device is estimated using the temporary communication. A geographical location of the wireless communication terminal is calculated based on multiple estimated values corresponding to the respective multiple geographical positions of the interrogation device.

  • Patent number: 9779342
    Abstract: A radio frequency identification (RFID) reader sequentially carries out inventory rounds with passive RFID sensor tags. Each RFID sensor tag has at least one sensing element arranged to sense a predetermined quantity. The reader reads one value of the predetermined quantity based on a backscattering modulation frequency used by the passive RFID sensor tag during each inventory round and releases the RFID sensor tag prior to reading next value of the predetermined quantity based on a backscattering modulation frequency used by the passive RFID sensor tag during a subsequent inventory round. If the passive RFID sensor comprises two or more sensing elements having different sensor characteristics, the reader reads one of the sensing elements of the passive RFID tag during one inventory round and releases the passive RFID sensor tag prior to reading another one of the sensing elements of the passive RFID sensor tag during a subsequent inventory round.
