Abstract: The proposed system, Delayed Telop Aid (DTA), improves the teleoperator's ability to control the vehicle in a three step process. First, DTA predicts robot motion given the operators commands. Second, DTA creates synthetic images to produce a video feed that looks as if the robot communication link had no delay and no reduced bandwidth. Finally, DTA performs closed loop control on the robot platform to ensure that the robot follows the operator's commands. A closed loop control of the platform makes sure that the predicted pose after the delay (and therefore the image presented to the operator) is achieved by the platform. This abstracts away the latency-sensitive parts of the robot control, making the robot's behavior stable in the presence of poorly characterized latency between the operator and the vehicle.

Abstract: Methods for performing power management of InfiniBand (IB) switches and apparatus and software configured to implement the methods. Power management datagrams (MADs) are used to inform IB switches that host servers connected to the IB switch's ports are to transition to a reduced-power or offline state or have returned to a normal operating state.

Additionally, when all of a switch's ports are connected to idle or offline servers the SMA may put the switch's core switch logic into a reduced-power state.
