  • Publication number: 20190369177
    Abstract: A power supply apparatus for a magnetic resonance apparatus has a power supply terminal module with a power supply unit and a reference voltage pull-down unit, and a load terminal module with a voltage comparator connected to a load power-feed terminal, which compares a nominal voltage and an actual voltage of the load power-feed terminal. A counter begins counting when the actual voltage is lower than the nominal voltage, and keeps its count unchanged when the actual voltage is equal to the nominal voltage, and emits a signal corresponding to the count to a digital-to-analog converter, connected to a phase inverter, which converts the digital signal to a positive analog voltage. A phase inverter is connected to an output voltage reference terminal of the power supply unit, and inverts the phase of the analog voltage to produce a negative analog voltage that compensates voltage drop loss on a cable between the power supply and the load power-feed terminal.

  • Patent number: 10488476
    Abstract: An RF choke resonator assembly has a cylindrical magnetic field shielding case with openings at two ends thereof, a magnetic field shielding plate and a winding skeleton, and a capacitive plate inside the case. The magnetic field shielding plate closes the opening at one end of the case, and has a through-hole allowing a cable to pass there through. The cable is wound on the winding skeleton. The capacitive plate is disposed opposite the magnetic field shielding plate in the case, separated therefrom by the winding skeleton, and is electrically connected to the case in a closed manner. The capacitive plate has a through-hole allowing the cable to pass there through. The capacitive plate is remote from the other opening case end opposite the opening closed by the magnetic field shielding plate. An insulation space is formed at that other opening, having a length in the axial direction greater than or equal to one quarter of the length of the magnetic field shielding case in the axial direction.

  • Publication number: 20190331745
    Abstract: A radio-frequency system for a magnetic resonance apparatus has a local coil, a body coil, and an impedance adjusting shield. The body coil is wirelessly power-coupled with the local coil such that the body coil serves as a transmitting coil for radio-frequency signals and the local coil serves as a receiving coil for magnetic resonance signals. The local coil is disposed in an internal cavity of the impedance adjusting shield. An impedance of the local coil is adjusted by the impedance adjusting shield so as to match the impedance of the local coil and the body coil. The impedance adjusting shield has a frequency modulation element that adjusts the resonance frequency of the local coil. The body coil couples power to the local coil, and the impedance adjusting shield effectively reduces energy transmission efficiency loss caused by reflection, thereby improving energy transmission efficiency.

  • Publication number: 20190044751
    Abstract: Systems and methods for carrier sense multiple access (CSMA) protocols for power line communications (PLC) are described. In some embodiments, a method may include performing a virtual carrier sensing operation and, in response to the virtual carrier sensing operation indicating that a communication channel is idle, calculating a contention window. The method may also include performing a physical carrier sensing operation subsequent to the virtual carrier sensing operation, the physical carrier sensing operation based, at least in part, upon the contention window. In response to the physical carrier sensing operation indicating that the communication channel is idle, the method may then include transmitting data over the channel. In other embodiments, another method may include determining that a data transmission is a unicast transmission and that an acknowledgement message has not been received.

A second type of traffic may be transmitted from the gateway AP to the station via at least one relay AP. The first type of traffic may include low-throughput traffic and may be transmitted over a long-range radio link (e.g., 2 GHz band link or sub-1 GHz band link). The second type of traffic may include high-throughput traffic and may be transmitted over at least one short-range radio link (e.g., 5 GHz band link). The gateway AP may receive low-throughput traffic directly from the station and high-throughput traffic from the station via the at least one relay AP.

  • Patent number: 9614229
    Abstract: Non-flammable electrolyte compositions for lithium metal primary batteries and the cells containing these electrolytes are described. The electrolyte compositions comprise one or more partially or fully fluorinated functionalized short chain polyethers with one or more lithium salts, and may include one or more cosolvents, and may have one or more fire retardants added. Said short chain functionalized fluorinated polyethers have much better ionic conductivity than the alkyl terminated fluorinated polyethers or long chain perfluoropolyethers, which provide superior flame resistance without sacrificing overall battery performance. Heat resistant, non-flammable primary lithium cells are also disclosed.
