  • Publication number: 20130061129
    Abstract: A computer-implemented system is provided for monitoring performance of a media player launched by a web browser. The media player is referenced by a document that defines a web page and is implemented as a plug-in to the web browser. Upon accessing the web page, the web browser launches the media player. The media player in turn launches a performance monitor that is implemented as a plug-in to the media player. The performance monitor subscribes to event listener objects exposed by the media player and receives event data that is reported by the event listener objects. Performance metrics pertaining to the media player are derived from the event data.

  • Publication number: 20110213594
    Abstract: It is an object of the present invention to accomplish both improvement of a calculation precision and reduction of a calculation time in prediction of a welding distortion of a large welded structure. A method of modeling a welded structure subjected to analysis by generating a mesh and performing thermo-elastic-plastic analysis thereon constructs a global model of the welded structure, and extracts a local model including a welded part from the global model. Next, the method constrains a boundary part of the extracted local model with the remaining portion of the global model, performs thermo-elastic-plastic analysis, and pastes the local model including the analysis result of the thermo-elastic-plastic analysis on the remaining portion of the global model, thereby reconstructing the global model. Thereafter, the method releases the constraint on the boundary part, and performs elastic analysis on the global model, thereby calculating a distortion of the welded structure.

  • Patent number: 6657333
    Abstract: A rotating coupling allows a vacuum chamber in the rotor of a superconducting electric motor to be continually pumped out. The coupling consists of at least two concentric portions, one of which is allowed to rotate and the other of which is stationary. The coupling is located on the non-drive end of the rotor and is connected to a coolant supply and a vacuum pump. The coupling is smaller in diameter than the shaft of the rotor so that the shaft can be increased in diameter without having to increase the size of the vacuum seal.
