  • Publication number: 20050138560
    Abstract: A method and apparatus for broadcasting live personal performances over the Internet employs a web server to manage scheduling and broadcasting of the performances over the Internet, as well as collections and payments for products and services sold by presenters to viewers in conjunction with their performances. The server receives audio/video data from presenter operated computers through an uploaded presenter program, and relays the received audio/video data to viewer operated computers for viewing in media players invoked by their web browsers responding to an uploaded HTML document or JAVA applet. Viewers select performances to view from a program schedule provided on a webpage hosted by the web server. Both viewers and presenters are registered with the web server to facilitate payments for products and services, and their financial information stored in a secure user database.

  • Patent number: 6874086
    Abstract: A computer system includes a web client having a client based program residing on it, a firewall having a protocol proxy residing on it, and a host server having an application program and a special window manager residing on it. All communications between the protocol proxy and the application program go through the special window manager. The web client communicates with the firewall through the Internet, and the firewall communicates with the host server through a LAN. The client based program employs HTTP, and the special window manager employs a persistent connection, socket-based protocol. The protocol proxy establishes and maintains a persistent connection with the special window manager, and communicates information back and forth between the client based program and the application program through the special window manager by first protocol translating the information between HTTP and the special window manager's persistent connection, socket-based protocol.

  • Publication number: 20050055642
    Abstract: A method of conducting an interactive design conference over the Internet, comprises: selectively admitting clients communicating through web browsers over the Internet to an interactive design conference; receiving a graphics file indicative of a design from one of the clients; and transmitting the graphics file to the other clients so as to be viewable as a graphics image through graphics file readers in the client web browsers. The graphics file is generated by a snapshot program previously transmitted to a client initiating the design conference and controlling the design database. Java applets are transmitted to each of the design conference participants to facilitate communicating annotations of the graphics image and messages between clients through their web browsers.

  • Publication number: 20030120979
    Abstract: A method and apparatus for remotely debugging an application program over the Internet is described. A software vendor provides an interface program along with an application program to a customer. The interface program detects a debug request initiated by a customer operator on a customer computer, and establishes a connection with a debug program on a vendor computer over the Internet. The interface program takes over control of the application program from the customer operator, and takes various actions including running a diagnostic sequence received from the debug program on the application program to debug the application program.

  • Publication number: 20030085923
    Abstract: A method for conducting a collaboration session, comprising: launching a collaboration session through a program on a computer so as to communicate with other computers concurrently logged on a network; and generating a graphics file including pixel information of a graphics image displayable on a display screen of the computer for transmission to the other computers so as to be viewable through graphics file readers associated with web browsers of the other computers during the collaboration session.

  • Patent number: 6510543
    Abstract: A method and apparatus for rendering an integrated circuit design layout is described. Graphics files are generated for selected zoom-in factors from cell-based information of the integrated circuit design, and stored in memory. When a computer operator selects a zoom-in factor greater by a predetermined amount than the largest of such selected zoom-in factors, a selector enables a rendering engine to render the integrated circuit design layout from the cell-based information. On the other hand, when the computer operator selects a zoom-in factor less than the largest of such selected zoom-in factors plus the predetermined amount, the selector enables a graphics processor to render the integrated circuit design layout from appropriate ones of the graphics files.

  • Patent number: 6507940
    Abstract: A method generates information for a window view of an integrated circuit from layout-formatted data such as GDSII formatted data. The method includes generating outer boundary boxes for structures of the integrated circuit from the layout-formatted data, generating a build file by including information of structures having outer boundary boxes completely or partially in a window, and generating information of the window view from the information thus included in the build file. In generating the build file, information of structures having outer boundary boxes completely outside the window are excluded from the build file. Also excluded is information of structures having areas less than a threshold value.
