  • Publication number: 20150372362
    Abstract: A feeding network is realized by dielectric phase shifting module. The module includes a dielectric device into which interlayer space is defined, a first conductor and a second conductor disposed side by side into the interlayer space and a third conductor located outside of the interlayer space and connected, at different locations, to one end, located at a same side, of each of the first and second conductors. Another end of the first conductor is defined as an input end, while another end of the second conductor and any end of the third conductor are all defined as output ends. The dielectric device is configured to slide along a longitudinal direction of the first and second conductors under external force so as to change phase of signals fed in from the input end and fed out from the output ends. Two dielectric phase-shift modules constitute a phase-shift unit thereof.

  • Patent number: 8457847
    Abstract: A powertrain includes a transmission coupled to a driveline. A method for monitoring torque of the driveline includes monitoring signals from first and second rotational sensors located at respective first and second rotationally-coupled positions of the driveline separated by a distance along the driveline, determining rotation of the driveline at the first and second rotationally-coupled positions from said signals, determining a twist angle derived from a difference between the rotations of the driveline at the first and second rotationally-coupled positions, calculating a driveline torque corresponding to the twist angle, and controlling operation of the powertrain in response to the driveline torque.

  • Patent number: 8090512
    Abstract: A method optimizes a fill event of an apply chamber of a fluid-actuated clutch, and includes determining input values describing the fill event, and then estimating a fill time using the input values. The method includes filling the apply chamber using the estimated fill time (EFT) or within an allowable range of the EFT. The input values can include a command line pressure, command fill stroke pressure, and an estimated viscosity of the fluid, although other values can be used. The input values are processed through a neural network having an input layer, an optional hidden layer, and an output layer. An assembly includes a fluid-actuated clutch having an apply chamber and a controller operable for estimating the fill time required for filling the apply chamber, and for controlling the fill of the apply chamber within the EFT.

  • Patent number: 7948574
    Abstract: An exemplary bezel includes two generally L-shaped bezel parts and two generally I-shaped bezel parts. All the bezel parts are joined end-to-end to cooperatively define a window therebetween, and this assembly is configured to accommodate a display panel. A minimum area of a rectangular region that can be occupied by the two generally L-shaped bezel parts alone includes a central unoccupied portion sufficient in size to accommodate the two generally I-shaped bezel parts.
