Abstract: Computer architecture and software for computer network communication such that data is at least partially converted between distinct transport protocols in order to optimize transmission of the data, and preferably to allow persistent connections to be maintained across different firewalls. As a preferred embodiment, the transport protocol conversion may cause the data to be converted between HTTP 1.1 protocol, to allow a persistent connection originated across port 80 of a first firewall, and a different protocol, to allow a persistent connection across a second firewall. The protocol conversion of the present invention is especially useful in connection with collaborative application software, wherein the collaborative server and its associated clients are respectively more amenable to different transport protocols.

Abstract: According to one embodiment of the invention, a method for determining deformation of a surface of a material is provided. The method includes receiving, at a computer, an elastic deformation range and a plastic deformation range of the material. The method also includes modeling a region of the material with a mesh. The mesh includes a plurality of elements. The method also includes determining, by performing a finite element analysis on the mesh by the computer, a displacement for at least one point on each of the elements. The displacement results from a set of modeled boundary conditions. The finite element analysis includes recurrently approximating the modulus of elasticity for each element according to the elastic deformation range and the plastic deformation range. The act of approximating is based on a value of strain calculated from a previously calculated element displacement.

Abstract: A system and method for evaluating a product Bill Of Materials (BOM) against a set of measurable criteria. A Bill Of Materials (BOM) is a hierarchical representation of the product in terms of its constituent parts. The parts can be components or sub-assemblies or commercially available parts. Each “Node” in a BOM hierarchy has certain properties, and each node may also have relationships with other entities.

Various embodiments of the process include generating product definition templates for each node in a product model, then applying knowledge-based engineering processes and tools in conjunction with interpart modeling functionality to automate the architectural change using the product definition templates.

Abstract: A system and method for creating a datum reference frame includes selecting a first datum, wherein the first datum comprises a plurality of faces. A first definition for the selected first datum is determined. One or more second datums, based on the determined first definition, are automatically determined, wherein the second datum comprises a plurality of faces. The second datum is selected. A second definition for the selected second datum is determined. One or more third datums based on the determined second definition, wherein the third datum comprises a plurality of faces, are automatically determined. The third datum is selected.

S ( u ? ( t i ) , v ? ( t i ) ) ? w = L ? ( t i ) .

Abstract: A method and system for applying constraints to a wireframe chain of curves for Computer-Aided Design (CAD) is disclosed, whereby a geometric constraint network can be expanded to include chains of curves as types of wireframe entities. As such, a chain of curves can be represented as one composite curve. As a result, a constraint solver can generate and/or maintain any constraint on a chain of curves, which enables the constraints to be solved while moving along the curves independently from the chain's geometry and topology changes.

Abstract: The processing system 10 is disclosed which uses a user interface 12 to interact with the search and control engine 16 and the display engine 18. The search and control engine 16 operates on a data set 14 to identify specific elements within a directory structure. Display engine 18 compiles the identified elements in a tree table 20 to format a display 22 associated with the directory structure. Pruning indicator 34 and a sibling pruning indicator 36 are used in the display 22 to inform the user that intermediate directory structures and sibling elements have been omitted from the display in order to show the identified elements in a truncated context within the complex directory structure.

Abstract: A system and method for analyzing network traffic between a client system and multiple mirror systems, to determine the most efficient data transfer paths for accessing the mirrored data. Accordingly, a set of network probes are passed between network point pairs. After doing so, the resulting figures are analyzed using a first-order linear equation to determine which pairs are “closest” in terms of data transfer efficiency in a specific direction. Using the closeness results, the optimal data paths for large data transfer are determined.
