    Abstract: An RF device comprising a plurality of drift tubes, each drift tube having a plurality of gaps defining resonant cavities, is immersed in an axial magnetic field. RF energy is introduced at an input RF port at one of these resonant cavities and collected at an output RF port at a different RF cavity. A plurality of electron beams passes through these drift tubes, and each electron beam has an individual magnetic shaping applied which enables confined beam transport through the drift tubes.

    Abstract: A data switching system is described to allow arbitrary types of connections to be established over arbitrary link types that include link types that do not inherently support virtual circuits. The data switching system includes a label switching system to establish virtual circuit connections over any link types. The data switching system also includes a connection routing and signaling controller, coupled to the label switching system to determine routes for connection over any link types.

    Abstract: Disclosed is a system, method, and program for magnifying displayed content downloaded from a server over a network. Information is received indicating selection of a region of the displayed content to magnify. A determination is made of at least one region of the selected region including image content. The server maintains a high resolution file version and a low resolution file version of the image content. A determination is then made as to whether the selected image content from the displayed image file is the low resolution file version. If so, a command is generated to retrieve from the server specific byte locations from the high resolution file version including the image content in the selected region. The specified bytes are less than all the image data bytes in the high resolution version of the file if the image content in the selected region comprises less than all of the image content maintained in the high resolution version of the file.

    Abstract: A connection control interface for switches in a network is provided. The connection control interface allows the multiservice switch to provide a number of switch resource partitions to a number of independent controllers coupled to the switch. The switch resource partitions comprise a number of subsets of switch resources that define a number of independent subset networks of a physical network. The connection control interface allows the independent controllers to control the connections of the switch using the number of switch resource partitions. The independent controllers each use one of a number of control systems, the control systems comprising a network software level. The independent controllers comprise a virtual switch interface having a master component and a slave component where the master and slave components may be hosted on different processors. The slave components may be hosted on a control card that controls a number of port cards of the switch or on a port card processor. The switch and the independent controllers are resynchronized when discrepancies are detected between the connections on the switch and those expected by the each of the plurality of independent controllers.
