    摘要: A method and apparatus for operation in a multi-frequency band wideband system in the presence of an interference, the method comprising the steps: receiving signaling in a plurality of wideband frequency sub-bands, each wideband frequency sub-band having a different center frequency, wherein a bandwidth of each wideband frequency sub-band is at least 2 percent of a center frequency of the wideband frequency sub-band; detecting an interfering signal having signal energy in a portion of a respective sub-band of the wideband frequency sub-bands; modifying at least one of a center frequency and a bandwidth of the respective sub-band in order to operate in the presence of the interfering signal; and instructing a transmitting device transmitting the signaling to transmit subsequent signaling accounting for the modification of the center frequency of the respective sub-band.

    摘要: An electro-hydraulic control system is provided for a transmission with a torque-transmitting mechanism that has a dual area piston. When pressurized fluid is provided to a first of the two piston areas, the position of a spring-biased shift valve controls whether pressurized fluid communicates with the second piston area. A solenoid valve in fluid communication with the shift valve is energizable to direct pressurized fluid to the shift valve to urge the shift valve to the unstroked position to which the spring also urges. The shift valve may also be urged by pressurized fluid to the stroked position, but only when the solenoid valve is not energized. The spring maintains the shift valve in the unstroked position when pressurized fluid is directed to the shift valve to act both against and with the spring.
