    摘要: Superplastic metal alloys having a high defromation rate are disclosed. Their structure is characterized by the presence of at least two principal constituents, the major one of which is of a particulate globular or elongated shape while the minor one surrounds the first completely or partially in the form of a particle on the boundry surface of the major constituent which is less than 10 .mu.m thick. This invention can be applied to the shaping of alloys in the superplastic state at a high deformation rate above 100% min.sup.-1.

    摘要: An enhanced reality maintenance system for operating in a hazardous environment employs an environment modeler which creates a computer model of the environment. An environment renderer creates a plurality of images, each corresponding to a viewing location and orientation, `viewpoint`. A remotely operated manipulator arm is attached at a fixed end to a stationary structure, has a utility package, such as a video camera, attached to a distal end, and actuators which move the manipulator arm to desired locations within the environment. The position and orientation of the manipulator arm, are determined by a position and attitude (P&A) sensing unit. This information is passed to an manipulator arm renderer which creates an image from a prestored model of the manipulator arm, viewed from several different viewpoints. The may be interactively determined as an offset from the current position and orientation of the utility package. Alternative embodiments include an image archive and comparison unit capable of storing images linked to information of the image acquisition, retrieving stored images and transforming the images to match the image acquisition parameters. Also, another embodiment employs an automated positioner, which desired path information is provided by an operator. The environment, manipulator arm size, shape, and motion constraints, are analyzed to result in a trajectory which most closely fits the provided path information which would not cause a collision with structures in the environment. This trajectory, if acceptable, is then automatically executed by an automated positioner.

    摘要: An enhanced reality maintenance system operates one or more remotely operated vehicles (ROVs) in a hazardous or inaccessible environment. A computer model of the environment is created from spatial parameters provided to the system. Positions and orientations of moving objects are monitored. The projected course of the moving objects is extrapolated and constantly updated. An automated flight planner, receives desired destinations from an operator, analyzes the environment, the projected courses of moving objects and planned trajectories of other ROVs, and selects a planned trajectory of a selected ROV through the environment without collision.
