  • Patent number: 9033852
    Abstract: In hydraulic control, an electronic control unit controls controlled hydraulic pressure of a control valve in order to control a hydraulic oil amount in a torque converter and a hydraulic oil pressure of a forward-reverse travel switching mechanism, and the electronic control unit increases the controlled hydraulic pressure when the hydraulic oil amount in the torque converter is insufficient at an engine start or immediately after the engine start in comparison with a case where the hydraulic oil amount in the torque converter is sufficient. The hydraulic control device includes: the torque converter; the forward-reverse travel switching mechanism; the control valve configured to change the hydraulic oil amount in the torque converter and the hydraulic oil pressure of the forward-reverse travel switching mechanism by changing the single controlled hydraulic pressure; and electronic control unit.

  • Patent number: 8627403
    Abstract: Provided are, among other things, systems, methods and techniques for determining applicability of a policy defined by reference to a source document. A first sketch that was generated based on content of the source document is obtained, and a matching criterion is defined based on the first sketch. Also obtained is a second sketch that was generated based on content of a potential target document. A determination is made as to whether the policy applies to the potential target document based on whether the second sketch satisfies the matching criterion and, if the policy applies, a notification regarding applicability of the policy automatically is provided and/or an action automatically is blocked so as to prevent a violation of the policy.

  • Patent number: 7634575
    Abstract: A method for clustering data streams. Specifically, one embodiment of the present invention discloses a method for clustering data streams for use in a virtual environment. The embodiment of the method begins by determining a cluster of receiving nodes in the virtual environment. Each of the cluster of receiving nodes have associated values for at least one clustering parameter that as a set satisfies a test. Then, the embodiment continues by generating a common data stream based on the clustering parameter. Thereafter, the embodiment sends the common data stream from a sending node to the cluster of receiving nodes.
