  • Patent number: 7000031
    Abstract: A method of providing synchronous transport of packets between asynchronous network nodes. An asynchronous network node capable of transmitting and receiving packetson the asynchronous network is designated as a master node. Each non-master asynchronous network node which desires to synchronously transport packets across the asynchronous network is designated as a slave node. Best arrival times for packets transmitted from slave nodes to the master node are communicated from the master node to the slave nodes. Bestpacket assembly times for packets to be transmitted by the particular slave node to the master node in the future for the packets to be received by the master node at future master clock referenced best arrival times are determined. Packets for transmission at slave nodes are prepared and transmitted according to determined future bestpacket assembly time information.

  • Patent number: 7000008
    Abstract: Disclosed is a method, system, and program for providing data updates to a page, wherein the page includes multiple regions of dynamic content that may be separately updated independently of each other. The regions of the page are displayed within a presentation program executing on a client. A server transfers the page to the client over a network. The server detects state changes and queues information on the state changes. The server further generates an update package including content indicating the state changes and sends the update package to the client. The presentation program in the client renders the information on the state changes to the regions of the page including the dynamic content modified by the content indicating the state changes.

  • Patent number: 6975976
    Abstract: Simulation continues to be the primary technique for functional validation of designs. It is important that simulation vectors be effective in targeting the types of bugs designers expect to find rather than some generic coverage metrics. The focus of this work is to generate property-specific testbenches that are targeted either at proving the correctness of a property or at finding a bug. It is based on performing property-specific analysis on iteratively less abstract models of the design in order to obtain interesting paths in the form of a Witness Graph, which is then targeted during simulation of the entire design. This testbench generation framework will form an integral part of a comprehensive verification system currently being developed.

  • Patent number: 6970813
    Abstract: A system and method that facilitates the modeling of an architecture through XML configuration is presented. Using this system and method, system developers that are developing a modeled architecture may, before system implementation begins, visualize and understand the system architecture and behavior. Similarly, during the development and deployment phases, developers may monitor different graphical views and/or the controller implementation in order to determine the look and/or feel of the application. Accordingly, different view and/or controller implementations may be plugged into the present invention to give a different look and/or feel. The application may also be adapted to any system that uses any middleware or protocol to communicate.

  • Patent number: 6965939
    Abstract: A method, apparatus, and computer implemented instructions for handling requests in a network data processing system. The network data processing system includes a network and clients connected to the network. A first server is present in which the first server receives a request from a client to access a resource, performs an authentication process with the client, add information to the request in which the information indicates that the request is from a trusted source to form a modified request, and sends the modified request for processing. This modified request is received by a second server. This second server determines whether the first server is a trusted server based on the information, and provides access to the resource in response to a determination that the first server is a trusted server. If the second server receives the request directly from a client, it would process the request by itself instead of basing its trust on any of the known first servers.

  • Patent number: 6965913
    Abstract: The invention is an Internet access system reducing Internet traffic and delays in content presentation. It puts together interactivity of the Internet and congestion-free content delivery inherent in broadcast radio and television. An access server located at a broadcast center receives clients requests for Internet objects (web pages, music files etc.) via a two-way medium, downloads from the Internet a single copy of that object no matter how many clients have requested the object and then retransmits the copy in a broadcast manner so that all clients requested the same object could download it simultaneously. The system provides a repeated transmission of objects in high demand to reduce interaction between Internet clients and access server while operating in two modes of content delivery: an immediate delivery on request and a planned delivery according to a schedule. In both modes users receive Internet content of their choice at the time of their choice.

  • Patent number: 6934736
    Abstract: A “cookie” is a set of information, such as user information and preferences, used by web sites to customize information for a user. A number of web sites register with a “cookie server” and provide the server with information regarding what data fields are expected in cookies submitted from clients to the web site. When a client subsequently browses to that web site, the client first checks with the cookie server for any expected cookies. The cookie server uses the cookie requirement information for that web site, along with user specific information, to generate one or more cookies. The cookie server then transmits the one or more cookies to the client. The client then transmits the one or more cookies to the web site so that the web site may provide a customized web page.

  • Patent number: 6934592
    Abstract: A household appliance is provided with a visual display, as well as a control system which enables the visual display to be used in an advertising mode of operation. The advertising mode can be selectively operated in either automatic or interactive formats. In the automatic format, a series of screens are successively displayed on the screen in order to advertise various features and advantages of the appliance. In the interactive format, the consumer can enter desired selections through the screen as if the appliance was actually in use. The appliance then simulates an operation cycle based on the selections made. The selections are preferably stored in a volatile memory location such that the control system reverts back to default settings and options, either after a preset idle period or upon establishing an OFF condition for the appliance.

  • Patent number: 6922607
    Abstract: In a numerically controlled method of moving an object to be controlled along a predetermined locus, controlling control axes, the locus is made approximate to a spatial polynomial, a polynomial is converted into a polynomial as time function, the polynomial converted as time function is distributed to each control axis, control command in each control axis is produced on the basis of the polynomial distributed to each axis as time function, and the object to be controlled is moved along the locus, controlling each control axis on the basis of the control command. The velocity, the acceleration and the jerk of the object to be controlled can be easily obtained concerning each control axis in advance by differentiating the polynomial expressed by time function. The object to be controlled is controlled so as to move along the locus expressed by the polynomial, feeding irregularity or position shift is reduced and curved face machining at high accuracy is possible.

  • Patent number: 6917838
    Abstract: An open-loop and closed-loop control method is described for starting up or shutting down a process component of a technical process. At least one manipulated variable that is fed to the process is formed by a control device and an upstream model-assisted pilot control. The pilot control contains an optimizer and a process model. The optimizer is fed at least one command variable for the technical process. At least one optimized model manipulated variable which the optimizer outputs is fed to a process model of the pilot control and, is added to at least one output variable of the control device to form the manipulated variable. A model output variable of the process model is fed to the control device as a set-point and fed back to the optimizer along with variables which cannot be measured in the technical process. A device for implementing the method is also described.

  • Patent number: 6748279
    Abstract: A factorial experiment is conducted on a manufacturing process to generate a response matrix. The responses are used to calculate individual contrasts in a document as well as replicates effects. The contrast sums are also calculated and displayed in the document. The largest of the contrast sums are identified, and effects associated with those contrast sums are tested for significance using an end count method. The information from the process transformed into “significant effects” information is used to adjust process variables to improve the manufacturing process by avoiding the effect or imparting it to a measurable response of the process.
