  • Publication number: 20210009218
    Abstract: The present invention discloses a method of tracking control for a foot force and moment of a biped robot. According to the method, a double-spring damping model is designed, and a force tracking controller is designed by using an LQR optimization method, so as to realize tracking of the foot force and moment of the biped robot. Further, a desired force on a foot and a desired moment on the foot are calculated through a planned ZMP distribution method, thereby eventually achieving better ZMP tracking of the biped robot and adapting to ground of certain unevenness.

  • Publication number: 20190034229
    Abstract: An electronic device monitors a volume of data processed by the electronic device within a first monitoring time segment, where a processor of the electronic device is configured to be in a first working mode, and the processor processes data in a poll mode driver (PMD) manner in the first working mode. The electronic device switches the processor from the first working mode to a second working mode when it is determined, according to the volume of data processed by the electronic device within the first monitoring time segment, that the processor is idle within the first monitoring time segment, where the processor processes data in the PMD manner and a sleep manner in the second working mode.

  • Patent number: 8856317
    Abstract: In one embodiment, a method includes receiving at one of a plurality of servers, a request from a client for a secure communication session, storing context information associated with the secure communication session at a virtual context server in communication with the servers, and establishing the secure communication session between one of the servers and the client. The context information includes a session identifier, a secret, and a session state. The stored context information is available to the servers to allow the secure communication session to move between the servers. An apparatus for secure data transfer in a virtual environment is also disclosed.

  • Patent number: 7509431
    Abstract: A method is disclosed for performing message and transformation adapter functions in a network element on behalf of an application. According to one aspect, the network element determines an application layer message that is collectively contained in payload portions of data packets. The application layer message conforms to an application layer protocol, such as Hypertext Transfer Protocol (HTTP). The network element determines the application layer protocol to which the application layer message conforms. Based on the application layer protocol, an adapter is selected from among a plurality of adapters that are accessible to the network element. The application layer message is provided to the selected adapter, which converts the application layer message into a “canonical” message that is not specific to any particular application layer protocol.
