Systems and methods are described for mobile device collaboration. An exemplary collaborative architecture enables aggregation of resources across two or more mobile devices, in such a manner that the aggregation of resources is practical even considering the miniaturized and limited battery power of most mobile devices. In a video implementation, the exemplary collaborative architecture senses when another mobile device is in close enough proximity to aggregate resources. The collaborative architecture applies an adaptive video decoder so that each mobile device can participate in playing back a larger and higher-resolution video across combined display screens than any single mobile device could playback alone. A cross-display motion prediction technique saves battery power by balancing the amount of collaborative communication between devices against the local processing that each device performs to display visual motion across the boundary separating displays.

The present invention discloses a support leg and a mobile offshore work platform having that leg. The disclosed support leg for a mobile offshore work platform comprises a support arm extending in a vertical direction, further comprising a support platform that has a cross section larger than that of the support arm, and that the lower end of said support arm is fixed to the upper surface of the support platform. When wind turbine installations or other offshore works are carried in sea areas of soft foundation ground, the support platform is supported on a soft foundation ground by a larger cross-sectional area, providing a greater support force and improving the stability of the mobile offshore work platform, and the mobile offshore work platform can be used to complete wind turbine installations and other predetermined works in sea areas of soft foundation ground.

A computer including a processor and a verification device. The processor in the computer performs the steps of authenticating a secure connection between a hypervisor and the verification device, measuring the identity of at least a portion of a select guest before the select guest executes any instruction, and sending a measurement of the identity of the select guest to the verification device. The verification device compares the policy stored in the verification device with the measurement of the select guest received by the verification device. The steps of authenticating, measuring, sending, and comparing are performed after receiving a signal indicative of a request to execute the select guest and without rebooting the computer.

The present invention discloses a gravity center adjustment device (2) for a wind turbine installation vessel. The gravity center adjustment device (2) is movably mounted to an outside of a vessel body (4) of the wind turbine installation vessel, so that the gravity center adjustment device (2) can selectively move in a plane substantially parallel with the vessel body (4). Since the gravity center adjustment device (2) according to the invention is movably installed to the vessel body and can move in a plane substantially parallel with the vessel body (4) so as to adjust the horizontal position of the gravity center of the installation vessel, its ability of adjusting the gravity center of the wind turbine installation vessel can be improved and the stability of the wind turbine installation vessel can be improved. Therefore, the operation efficiency can be improved and the cost of constructing a wind power plant on the offshore can be reduced. The present invention also discloses a wind turbine installation vessel including the gravity center adjustment devices (2) described above.

The present invention discloses a gravity center adjustment device for a wind turbine installation vessel, with the gravity center adjustment device (2) fixedly mounted to the outside of the vessel body (4) of the wind turbine installation vessel. The existence of the gravity center adjustment device (2) according to the present invention is independent from the vessel body and no longer limited by the size of the installation vessel and the size of the ballast bank provided in the vessel body of the wind turbine installation vessel. The size of the gravity center adjustment device (2) may be set as desired so that the adjustment ability of the gravity center adjustment device can be changed, whereby its ability for adjusting gravity center of the wind turbine installation vessel can be improved and the stability of the wind turbine installation vessel can be improved. Therefore, the wind turbine installation vessel can operate in an environment of poor weather condition, so that the operation efficiency can be improved and the cost of constructing a wind power plant on the offshore can be reduced. The present invention also discloses a wind turbine installation vessel including the above-mentioned gravity center adjustment device (2).
