    摘要： A computer implemented method for controlling a software defined network (SDN) is disclosed. The method includes providing one or more client portals configured for facilitating users controlling networked devices, generating configuration data based on input received from users via the client portals, and providing a master SDN controller for managing data flow control on the SDN network. The master SDN controller is operable to route data for the networked devices, generate a plurality of discrete co-controllers each associated with a particular end user with each co-controller having configuration data and routing data for an associated networked device, dispatching the co-controllers to the networked devices associated with the respective end users, installing the co-controllers on the networked devices, and registering the installed co-controllers with the master SDN controller for controlling the routing of data and configuration of the networked devices.

    摘要： Methods and apparatus for enhancing a search performance for timing includes a mobile station that detects a plurality of signals, each from one of a plurality of cells, wherein one of the plurality of cells is identified by the mobile station as a strong cell and the remaining cells are identified by the mobile station as weak cells. A first matched filter is applied to a signal from the strong cell to detect first parameters associated with the strong cell. A second matched filter is applied to at least one signal from one or more of the weak cells resulting in at least one second matched filter output. Interference is removed from the at least one second matched filter output to detect one or more second parameters associated with one of the weak cells and to establish a timing of one of the weak cells.

    摘要： Clutch cooling grooves formed on a friction plate are provided. The grooves are shaped to provide for substantially uniform steel disk temperatures in friction launch of a vehicle. The grooves are shaped such that the largest cross-sectional area is located adjacent to what would otherwise have been a hot area on the steel disk and the smallest cross-sectional area is located at the coolest location on the steel disk, at the cooling fluid inlet. Thus, the groove is shaped such that the smallest cross-sectional area is located at the cooling fluid inlet, the largest cross-sectional area is located between the cooling fluid inlet and the cooling fluid outlet, and the cooling fluid outlet has a cross-sectional area larger than the cooling fluid inlet and smaller than the cross-sectional area adjacent to the hot spot of the steel disk, between the cooling fluid inlet and the cooling fluid outlet.
