Title: Method and system for traffic management in packet networks using random early marking
Inventor: ZBORIL THOMAS GEORGE
IPC: H04L12/56
Filed: 2001-10-04
Abstract: The invention describes a method for traffic management in a packet network using random early marking.        For each packet flow, packets are randomly marked at the ingress of the network, while discard of the packets at the egress of the network is performed deterministically, i.e. in accordance with the predetermined rules. The step of random marking includes measuring parameters of the data flow, calculating marking probability by applying a mathematical function to the measured parameters, and generating a mark by applying a random logic function to the calculated marking probability. The packets are dropped at the egress of the network if the corresponding queues where the packets have to be stored are congested or full.        A corresponding system for traffic management in packet networks is also provided.

Patent CA-2364295-A1 (CA)
Title: Data parsing system for use in electronic commerce
Inventor: CLARKE WILLIAM D
IPC: G06F17/27
Filed: 2000-02-11
Abstract: A parsing technique suitable for use in electronic commerce that avoids the disadvantages of known monolithic parsers. The parsing system generates code specific to each input document and data stream type, which may then be updated as needed to handle document-specific idiosyncrasies without requiring modifications to the core parser code. As a user (10) defines parsing rules for extracting data from a representative sample document (15), a visual trainer (16) automatically generates code in the background, referred to as a filer (17), that is specific to that document and that embodies the rules for extracting data from that particular document. The generated code may be modified manually (18) as needed to account for any idiosyncratic conditions associated with the document. Each representative document has associated with it its own filer. A parsing engine (20, 21) comprises a collection of such individual filers appropriate for the types of documents that arise in any given organization. A mapping or other association is maintained between representative document types and their filers. In regular operation, a user selects a data set to be extracted from certain documents. When the parsing engine receives a document in an input data stream, the associated filer is loaded and parses that document for the selected data set. Then another filer is loaded in response to another input document, and so on. The filers may be especially efficiently generated using an object-oriented approach and then dynamically instantiated at run time as may be conveniently achieved, for example, in the Java programming language.

Patent CA-2368985-A1 (CA)
Inventor: STEPNIAK JACEK
IPC: F16H7/08
Filed: 2000-04-12
Abstract: A tensioner (10) for an endless belt comprising a stationary structure on which a pivotal tension arm (13) with an idler pulley (11) is mounted. A spring (15) between the tension arm and the stationary structure (16) acts to bias the pulley (11) against the belt, thereby applying tension. The invention includes a one-way device that is operable in response to the extent of pivotal movement of the tension arm (13) in the forward direction to establish different positions at which pivotal movement in the return direction is limited. A damping system (44) is used to restrict pivotal movement of the tension arm (13) as a result of sudden short-time vibratory movements or dynamic vibrations in cold conditions.

IPC: G01V1/20
Filed: 2002-01-24
Abstract: A system for, and method of, orienting seismic energy sources and seismic energy receivers to substantially separate a compressional wave from a vertical shear wave.      The method includes reflecting a seismic energy from a subsurface interface to produce a reflected seismic energy wave that has a compressional energy and vertical shear energy associated therewith. A first seismic energy receiver is oriented such that it is aligned with an angle of emergence of the reflected seismic energy wave to thereby maximize the vertical shear energy received by a second seismic energy receiver.

IPC: C21C7/00
Filed: 2000-03-29
Abstract: According to this treatment, calcium is added to ultra low molten steel or low carbon which is aluminum killed (or in the course of being killed) in order to form non-metallic deoxidation inclusions that have a melting point which is below the casting temperature; the molten metal is maintained in the chain of treatment ranging from the ladle refining installation to the copper mold with a low minimum low magnesium content of approximately 2 ppm. The inventive method increases the scope of fusibility of the inclusionary population of steels, thereby improving the castability of high aluminum-killed ultra low carbon grades without the need for argon bubbling.

Title: Document-classification system, method and software
Inventor: LOCKE JEFFREY
IPC: G06F17/30
Filed: 2000-05-05
Abstract: Every year, professional classifiers at West Group manually classify over 350,000 headnotes, or abstracts of judicial opinions across approximately 82,000 separate classes of the Key Number System (130). Although most headnotes are classified from the memory of classifiers, a significant number are difficult and thus costly to classify (130) manually. Accordingly, the inventors devised systems (120), methods, and software that facilitate manual classification (120) of headnotes and documents generally hard-to-classify and particularly headnotes. One exemplary system provides a graphical user interface (114) that concurrently displays an unclassified headnote (140), a ranked list of one or more candidate classes, a candidate class in combination with adjacent classes of the classification system (100), and at least one classified headnote associated with one of the candidate classes.
