  • Publication number: 20120173243
    Abstract: An expert conversation builder contains a knowledge database that includes a plurality of dialogues having nodes and edges arranged as directed acyclic graphs. Users and authors of the system interface with the knowledge database through a graphical interface to author dialogues and to create expert conversations as threads traversing the node in the dialogues.

  • Publication number: 20060276209
    Abstract: The present invention provides methods, systems, and computer program instructions for providing location-independent packet routing and secure access in a wireless networking environment (such as that encountered within a building), enabling client devices to travel seamlessly within the environment. Each client device uses a constant address. An address translation process that is transparent to the client and server is automatically performed as the device roams through the environment, enabling efficient client migration from one supporting access point to another. The secure access techniques provide user-centric authentication and allow policy-driven packet filtering, while taking advantage of encryption capabilities that are built in to the hardware at each endpoint.

  • Publication number: 20020032590
    Abstract: A method for allowing flexible creation and alteration of business processes within a commerce system includes using state machines to describe the actions that can be taken by particular roles at particular points in a process. The state machines are used by a commerce system to enforce validity of user actions, to track the execution of actions within an instance of the business process, to provide the user interface with a list of actions available to a user working on an instance of the business process, to provide coordination between state machines, and to allow different organizations to have varied business processes.

  • Patent number: 6044466
    Abstract: A dynamic derivation mechanism is defined which enables limited permissions to be dynamically and flexibly derived for executables based upon their authenticated description. The dynamic derivation mechanism uses the authenticated description to determine the maximal permissions that individual principals can delegate to the content. A principal's maximal permissions for content define a superset of the rights that that principal will actually delegate to that content. Although the maximal permissions are derived from predefined specifications, the specifications can be sensitive to runtime state on the downloader's system or previous delegations to enable the dynamic (i.e., runtime) derivation. Multiple principals can delegate a subset of their maximal permissions for the executable content. The mechanism uses policy for combining the delegated permissions into the content's runtime permissions.
