Abstract: A system and method for allocating bandwidth across a network to and from different end point nodes improves the predictability and efficiency of best effort network architectures. Advanced traffic processors associated with end point nodes detect and classify packets transferred across a network and allocate bandwidth. A packet policy module of the advanced traffic processor allocates bandwidth by applying policy definitions, flow ID rules, and flow policy maps to prioritize packet flows. In one embodiment, bandwidth is allocated on demand on a per-download basis so that bulk file transfers are provided substantially reduced download times through allocation of bandwidth for a premium fee.

Abstract: A Web-based video-editing system using a high-performance multimedia software library having a toolkit, the toolkit being a set of reusable, high-performance primitives and abstractions that are at an intermediate level of abstraction between C and conventional libraries. By decomposing common multimedia data types and operations into thin abstractions and primitives, programs written using the toolkit achieve performance competitive with hand-tuned C code, but which are shorter and more reusable. The toolkit programs can employ optimizations that are difficult to exploit in C and are impossible to use in conventional libraries.

Abstract: A partial evaluator, or pre-compiler, for a computer program enables a user to provide, at suitable places within a program, language constructs which cause certain expressions within the program to be evaluated at runtime or at partial evaluation time. These language constructs can be used to shorten runtime, such as by avoiding unnecessary duplication of code at runtime.

Abstract: A technique for processing natural language text uses a data structure that includes structure data in the text data. The structure data indicates an autonomous punctuational structure of the text, a punctuational structure that is independent of the lexical content of the text and therefore can be manipulated without considering the meaning of the words in the text. The data structure can be a tree in which each node has a textual type such as a paragraph, sentence, clause, phrase, or word. The data structure could alternatively be parallel data sequences, one with codes indicating the text's characters and the other with codes indicating textual types. The data structure is produced and maintained using a grammar of textual types, indicating for each textual type the textual types of units into which it can properly be divided. During editing, a text sequence is generated by applying rendering rules to the data structure, and the text is presented to the user based on the text sequence.

Abstract: A rope friction resistance exercise device (10) for swimmers is disclosed. The device closely simulates the arm movements of a swimmer while using the crawl stroke. The body member (26) has a fixed crosspiece (28) attached to one end and a rotatable crosspiece (30) attached to its other end. Crosspiece (30) is held on body member (26) by retaining ring (32). Rope (12) is looped over fixed crosspiece (28) and wrapped around the body (26). The ends (22 and 24) of rope (12) are threaded through opposite sides of a square-shaped ring (34) which is attached at two points to opposite sides of rotatable crosspiece (30). Body member (26) is perforated by offset holes spaced 30 degrees apart in two rows. A detent assembly (42) located inside the rotatable crosspiece (30) latches crosspiece (30) into particular positions. The amount of friction and therefore the amount of resistance may be increased by rotating crosspiece (30) through its twelve numbered positions in increasing numerical order.
