Patent CA-2540806-A1 (CA)
Title: Wheel for goods wagon and wheel set
Inventor: STEPHANIDES JOHANNES
IPC: B61K9/12
Filed: 2004-10-04
Abstract: The invention relates to wheels for goods wagons with small and large diameters, in addition to wheel sets equipped with wheels of this type for running gear, which is dependent on a highly passive radial positioning when negotiating curves and must remain stable at high speed. The inventive wheel profile is characterised as a result of the relatively large entry radius into the transition area from the running surface to the wheel flange by a low equivalent conicity. This enables a quieter running of the wheel set when the latter is travelling in a straight line. In curves, there is a sufficient rolling circle differential, permitting less wear and tear.

Title: Sea vessel docking station
Inventor: MILLHEIM KEITH
IPC: B63B35/44
Filed: 2006-04-20
Abstract: A system and method in which a buoyant central docking station captures, lifts and couples one or more other sea vessels is disclosed, wherein a flexible, modularized production system is quickly realized on a cost effective basis.  The capabilities of a number of older, less expensive, readily available vessels are combined to achieve an effective FPSO substitute that allows lower producing fields to be explored and produced in a profitable manner. The time horizon between initiation and consummation of field operations is reduced, and older vessels that might otherwise be scrapped or retired are again made useful and seaworthy in a safe and profitable exploration and production environment.

Patent CA-2558002-A1 (CA)
Inventor: DAVIES CHRISTOPHER MICHAEL
IPC: H04L12/24
Filed: 2005-02-16
Abstract: The present invention provides a network architecture. An embodiment includes a plurality of nodes interconnected by links. Each node can maintain knowledge of other nodes in a database. The database contains a list of other nodes in the network, and a 'next-best-step' for each of those other nodes, pointing to a neighbouring node that is the next best step to that other node. Where a particular node of the network is not in the list, then the next-best-step is assumed to be the next-best-step most commonly identified in the database.  Such a network will form a "core" wherein any node in the network can find any other node in the network by first seeking out that other node at the core.  Once the nodes locate each other via the core, a more optimum route forms in the network according to the most desirable path between those nodes.

Title: System and method for identifying optimized blood signal in medical images to eliminate flow artifacts
Inventor: ASHTON EDWARD
IPC: G01R33/561
Filed: 2005-03-18
Abstract: In a sequence of medical image data showing tumors and blood vessels, a plasma signal is optimized to avoid flow artifacts by receiving a user input of a blood region and using the user input to seed an automated search. Each voxel is scored by time point of maximum intake, slope at maximum intake, peak value and conformance to a gamma variate curve, and the voxels with the highest scores are included in the ideal plasma region of interest. Uptake curves for both tumors and plasma are determined and used to estimate a volume transfer constant.

Abstract: A method of computer-assisted price modelling is provided, which uses a reference price to assist in evaluating discretionary pricing of transactional services provided (i) by a professional among his own transactions or (ii) by a target professional among others' transactions. A universe of pricing episode data is segmented into groupings based on price predictive parameters. These data are then arranged in each grouping according to price. A reference price is determined within each grouping based on a predetermined level, rank or percentile. This reference price can then be used to evaluate the pricing episode data and provide various calculations or comparisons, including the revenue opportunity that could have been obtained by pricing at the reference price.

Abstract: Methods and apparatuses for automated conversion of color images to aesthetically enhanced gray scale images. In one embodiment, the mix of color channels of a color image is automatically determined as a result of analysis of the image for the generation of a gray scale image. In one example, the data of a color channel (e.g., Blue) that is not suitable for a gray scale representation is not used. The adjustment strength depends on the image itself. In one example, a stronger color channel is automatically weighted less than a weaker color channel for enhancement. In one example, after the contrast is further strengthened through nonlinear scaling, the boundary portion of the image is darkened to strengthen the edges and draw attention to the center of the image. Optionally, an attractive color balance adjustment is also made according to the gray levels to further enhance the appearance.

Abstract: A method and apparatus for determining a class signature from an article made of paper or cardboard in order to identify a generic type of class to which the article belongs. An optical beam illuminates the article and a detector arrangement collects data points from light scattered from many different parts of the article as the article is scanned by the beam. The class signature derives from intrinsic properties imparted to the paper/cardboard during manufacture by, it is believed, the screen used during dewatering of paper pulp. Detection of the class signature allows the manufacturer or the particular paper making machine that made the paper to be identified.
