  • Publication number: 20040083256
    Abstract: A system for real time image transmission monitoring for use in a network system connecting a server and a client. The system includes a remote image monitoring system having a VGA signal-gathering module to gather first and second frames from a client, and a VGA signal-gathering module. The VGA signal-gathering module defines each frame into a plurality of sub-frames, and numbers each sub-frame. Then, the contents of the sub-frames with the same number in the first and second frames are compared, and the content of the variation sub-frame in the second frame and its corresponding number are output to the server if the contents are different. The server replaces the content of the sub-frame with the number in the first frame by the received content, and thus forms the second frame to output.

  • Patent number: 5920412
    Abstract: A method and apparatus for optical signal routing in an optical network that includes one or more optical fibers to carry multiplexed signals. Each optical fiber may include a plurality of optical carriers with each optical carrier operating at a different wavelength. The optical network includes an optical network routing apparatus to receive the multiplexed signals from the optical fiber, to categorize the multiplexed signals as local signals or as non-local signals, to drop the local signals to a local switch, and to transmit the non-local signals to the optical fiber for further routing in the optical network. Advantageously, the transport of multiplexed signals on optical carriers of different wavelengths on a single optical fiber multiples by the number of optical carriers the bandwidth capacity of the optical fiber.

  • Patent number: 5888894
    Abstract: A method for reducing stray conductive material near vertical surfaces in semiconductor manufacturing processes comprising the following steps. Deposit the gate oxide, polysilicon and cap oxide layers. Apply a Poly1A mask. The Poly1A mask pattern comprises the Poly1 areas that are part of the final circuit layout as well as additional Poly1 areas that are included to provide planar surfaces to prevent stringer formation. Etch the cap, polysilicon and gate oxide layers to partially form the transistor gate structures. Form oxide spacers on the sides of the transistor gate structures. Apply a source/drain mask. Deposit source/drain dopants to form diffusions. Deposit an interlayer dielectric. Mask and pattern contacts to the diffusions and the Poly1 layer. Deposit blanket TiN/Ti layer(s). Pattern the TiN/Ti layer(s) using a TiN/Ti mask and a dry anisotropic etch. Patterning the TiN/Ti layer(s) may create TiN/Ti stringers along vertical surfaces of the interconnect layer.

  • Patent number: 5867502
    Abstract: A method and system for maximization of the use of bandwidth capacity of an optical network when adding a data stream received from a switch to the optical network. In one embodiment, a data stream is added to the optical network. A data stream is received from a switch and grouped into a destination group. The destination group is then sent to the network. In another embodiment, a method for dropping a data stream received from an optical network to a switch is provided. A segment is received from the optical network. If the segment is a private segment, then it is demultiplexed into at least one data stream. The data stream from the private segment is then sent to the switch. In still another embodiment, a method for providing an interface between a switch and an optical network is provided. In this embodiment, a data stream is received from the switch. The data stream is grouped into a destination group and the destination group is sent to the optical network.

  • Patent number: 4512349
    Abstract: A new method of tissue oxygen tension measurement which is suitable for human use utilizes an implanted Silastic tube which is inserted through four to five cm of subcutaneous tissue leaving the ends exposed. With the tube filled, for example, with a saline solution, reference and oxygen electrodes are inserted at the exposed ends and by the use of a polarographic potential the amount of oxygen which permeates through the tube from the tissue into the saline solution may be measured on a continuous real-time basis.
