  • Patent number: 12001672
    Abstract: An interface display method of an application is provided. The interface display method of an application may include: displaying a first user interface of the application; and in response to detecting a startup operation for a second user interface of the application, controlling states of components used to display the first user interface and the second user interface as a visible state, so that the first user interface and the second user interface are simultaneously displayed on a display panel, and the second user interface is a sub-interface of the first user interface.

  • Patent number: 11542758
    Abstract: The present invention relates to a linkage test apparatus for deepwater drilling riser and hang-off system. The linkage test apparatus includes a motion excitation system, a hang-off system and a riser system. The motion excitation system includes a six-degree-of-freedom excitation platform and sensors. The hang-off system includes a hydraulic cylinder actuating mechanism and a hydraulic system. The hydraulic cylinder in the hydraulic cylinder actuating mechanism is composed of an inner cylinder and an outer cylinder and it is fixed on the six-degree-of-freedom excitation platform by a spider. The inner cylinder of the hydraulic cylinder is hollow. A hang-off joint passes through the center of the inner cylinder, and a bottom of the hang-off joint is connected to the riser system via a rotating flange. The riser system is successively connected by multiple riser test joints, and the bottom is suspended with a lower marine riser package model.
