  • 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: 10170116
    Abstract: A system capable of generating and storing progress data associated with third party services. A voice enabled device may receive voice commands and the system may perform natural language understanding (NLU) to interpret the voice commands, determine a corresponding process and send instructions to a third party server associated with the process. In order to resume the process after the process is interrupted, the system may save and/or cause the third party server to save progress data and/or a checkpoint corresponding to a status of the process at the time that the process is interrupted. The system may use the progress data to resume the process at a later point based on the status. In addition, the system may track processes associated with saved progress data/checkpoints and may interpret incoming voice commands based on the tracked processes.

  • Patent number: 10170939
    Abstract: A foreign object detector detects a metallic foreign object between a first resonator and a second resonator which is composed of a parallel resonant circuit including a coil and a capacitor. The foreign object detector includes the first resonator; an oscillator circuit capable of oscillating at a first frequency (f1) which is lower than a resonant frequency (fr) of the second resonator and at a second frequency (f2) which is higher than the resonant frequency (fr); and a measurement circuit to measure changes in input impedance of the first resonator. The measurement circuit detects a metallic foreign object between the first resonator and the second resonator based on: changes in input impedance of the first resonator as measured by the measurement circuit while the oscillator circuit is oscillating at the first frequency f1; and changes in input impedance of the first resonator as measured by the measurement circuit while the oscillator circuit is oscillating at the second frequency f2.

  • Patent number: 10152435
    Abstract: A system includes a bus, at least one processor coupled to the bus, and a storage device coupled to the bus. The storage device includes storage class memory, a buffer; and a controller. The controller is configured to receive an instruction to provide data to the bus. Responsive to receiving the instruction to provide data to the bus, the controller is configured to retrieve data from the storage class memory, update the buffer to represent the data retrieved from the storage class memory, and output, at the bus, an indication that data responsive to the instruction to provide data to the bus is available at the buffer. The at least one processor is configured to refrain from modifying local data corresponding to the instruction to provide data to the bus after the controller receives the instruction to provide data to the bus and before the controller outputs the indication.

  • Patent number: 10146965
    Abstract: The invention relates to a method of reading RF transponders disposed in one and the same magnetic interrogation field, in which a magnetic coupling of the transponders is ensured with a passive resonant circuit during reading. The method is distinguished in that the passive antenna of the resonant circuit is associated with at least one transponder antenna, and the passive resonant circuit is tuned in such a way that the resonant frequency resulting from the association corresponds to one of the frequencies of the emission side bands of the transponder to be read. The invention also relates to the system corresponding to the method, a transponder structure and an object containing the transponder, in particular a travel document.

  • Patent number: 10142591
    Abstract: This disclosure is directed to facilitating voice and video communication between users independent of a location or a device. A communication request can specify users, who may be identified and located in their respective environments. For example, users can be identified and located using facial recognition imaging techniques and/or by monitoring a radio frequency (RF) signal associated with a device that is carried or worn by a user. After determining a location of a user, individual devices can be configured as a functionally grouped device to allow the users to communicate. For example, capabilities of a television, microphone, speaker, and imaging device can be combined to allow a video communication between users. Further, as a user moves around his or her environment, the location of the user can be tracked and additional functionally grouped devices can be provided for seamless communication.
