Patent CA-2194834-A1 (CA)
Title: Encoding and progressive transmission of progressive meshes
Inventor: HOPPE HUGHES H
IPC: G06T15/00
Filed: 1997-01-10
Abstract: An efficient, lossless, continuous-resolution representation (the "PM representation") of highly detailed geometric models for computer graphics specifies a succession of progressively more detailed polygonal meshes (i.e., "progressive meshes") as a base polygonal mesh and a sequence of complete mesh refinement transformations (eg., the vertex split transformation) that approximate the model at progressively finer levels of detail. Procedures for storing and transmitting geometric models using the PM representation address several practical problems in computer graphics: smooth geomorphing of level-of-detail approximations, progressive transmission, mesh compression, and selective refinement. An optimized mesh simplification procedure constructs the PM representation of a model from an arbitrary polygonal mesh, while preserving the geometry of the original mesh as well as its overall appearance as defined by its discrete and scalar appearance attributes such as material identifiers, color values, normals, and texture coordinates. In particular, the PM representation and these procedures preserve discontinuity curves such as creases and material boundaries of the geometric model.

Title: Method and apparatus for sodding microvessel cells onto a synthetic vascular graft
Inventor: MYERS KEITH
IPC: A61F2/06
Filed: 1996-02-01
Abstract: An apparatus for sodding onto the inner lumenal surface of a synthetic graft of harvested and concentrated microvessel endothelial cells from liposuctioned fat tissues, which harvested cells are formed into a "pellet" of isolated endothelial cells in loose aggregations, includes a sodding tube having a single rigid outer wall bounding a sodding chamber. A filter pack assembly is provided to communicate the pellet of cells from a processing vessel to the graft. This filter pack assembly includes a series of successively finer filter members cooperatively defining a series of turbulent-flow chambers in which aggregations of cells too large to pass through a particular filter are exposed to liquid flow turbulence which is effective to break up the aggregations. A check valve assembly ensures that liquid flow is unidirectional so that sodding of the cells onto the inner lumenal surface of the graft is not interfered with by possible liquid reflux, and sodded cells are similarly not dislodged from the graft by such liquid reflux.

Patent CA-2215712-A1 (CA)
Title: Video coder providing implicit coefficient prediction and scan adaptation for image coding and intra coding of video
Inventor: SCHMIDT ROBERT LOUIS
IPC: H04N19/593
Filed: 1997-09-17
Abstract: A predictive video coder performs gradient prediction based on previous blocks of image data. For a new block of image data, the prediction determines a horizontal gradient and a vertical gradient from a block diagonally above the new block (vertically above a previous horizontally adjacent block). Based on these gradients, the encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block.      The encoder determines a residual that is transmitted in an output bitstream. The decoder performs the identical gradient prediction and predicts image information without need for overhead information. The decoder computes the actual information based on the predicted information and the residual from the bitstream.

Title: Line system for playing field
Inventor: PREVOST JEAN
IPC: A01G9/28
Filed: 1998-05-26
Abstract: A method of visually marking a line in a natural grass turf playing surface by embedding a synthetic grass strip within the natural turf of football fields etc. The synthetic strip has a middle band of light coloured synthetic grass to mark the line and outer bands of green coloured synthetic grass which blend in with the adjacent natural grass. Installation commences with cutting a shallow trench in the turf surface. The synthetic grass turf marking strip is laid into the trench and resilient granular ballast is deposited on the strip backing between upstanding grass-like tufted ribbons.  The natural grass adjacent the outer green synthetic ribbons gradually grows into and blends with the outer edges of the outer synthetic green ribbon bands. The outer green coloured bands inhibit the lateral spread of natural grass over the light coloured middle band. The light coloured middle band of synthetic ribbons remain clear of natural grass to visually mark playing field lines in a permanent manner requiring significantly less maintenance than conventional line marking systems.

Title: Compositions for modulating intracellular inositol trisphosphate concentration and uses thereof
Inventor: ROSENBERG ABRAHAM
IPC: A61K31/7004
Filed: 1996-12-23
Abstract: Compositions and methods for the modulation of aberrant inositol trisphosphate concentration in neurons is disclosed. Inositol trisphosphate stimulates an increase in intraneuronal calcium ion concentration which can, if unregulated, lead to acute neurotoxicities following such insults as brain seizures, and brain anoxia/ischemia; and lead to chronic neurotoxicities in such diseases as Alzheimer's disease, Huntington's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Inhibited inositol trisphosphate production results in aberrantly low calcium ion levels leading to neuronal apoptosis.  The figure illustrates conversion of phosphitidyl inositol 4,5-biphosphate into diacylglycerol and inositol trisphosphate.

Title: Method and electrode structure for reducing the influence of electrode motion artifacts
Inventor: SINDERBY CHRISTER
IPC: A61B5/296
Filed: 1998-07-16
Abstract: A myographic probe for detecting an electrical signal produced by a muscle and for reducing the influence of electrode disturbances. The probe includes electrodes and a disturbance reducing interface covering each electrode thereby segragating the electrodes from the muscle. Electrode disturbances include problems such as those related to the motion of the electrodes, changes in the pressure applied to the electrode, and/or intermittent contact with sourrounding tissue. The disturbance reducing interface is ion permeable and is, when dry, less conductive than the electrodes. The disturbance reducing interface may comprise a matrix of permeable material such as a mesh, foam, or other porous materials. The probe may be in the form of a catheter and be advantageously used in a human cavity such as the oesophagus. Another advantage of the invention is the possibility of using electrodes which are different from conventional wound wire electrodes.
Patent CA-2243427-A1 (CA)

IPC: C07D213/82
Filed: 1997-11-19
Abstract: L'invention concerne de nouveaux dérivés de pyridinecarboxamide représentés par la formule générale (1) ou leurs sels physiologiquement acceptables. Dans la formule, n représente un entier compris entre 14 et 18; et R représente hydrogène ou alkyle C¿1?-C¿4? linéaire ou ramifié. Ces composés sont extrêmement efficaces pour inhiber un oedème cérébral, en particulier un oedème cérébral ischémique, et inhiber la mort neuronale différée (ou inhiber l'afflux de calcium dans les neurones). Ils s'utilisent comme inhibiteur de l'oedème cérébral ou comme remède aux troubles cérébrovasculaires, car l'oedème cérébral constitue un état pathologique accompagnant les troubles cérébrovasculaires, en particulier du type de ceux qui sont observés en phase aiguë. Ces composés ne provoquent pas d'hypotension et ne présentent pratiquement aucune activité affectant le comportement, deux effets étant supposés être des effets secondaires dans la thérapie des troubles cérébrovasculaires en phase aiguë. Ils constituent par conséquent un excellent remède à ces troubles. En outre, ils ont un effet protecteur sur le cerveau (par ex. un effet antianoxique), augmentent le flux sanguin dans le cerveau, et inhibent la péroxydation lipidique, ce qui renforce leur utilité comme remède aux troubles cérébrovasculaires.

Title: Fuel tank
Inventor: RICHTER BENNO
IPC: B60K15/077
Filed: 1998-07-23
Abstract: A fuel tank for a motor vehicle is provided in its interior  with  a  component  for  reducing  fuel  surge movements.  To avoid troublesome noises produced by fuel movement  the  component  comprises  a wall  element  at  a spacing from the end of the tank that is the front end or the rear end in the direction of travel. The wall element extends at least over a substantial part of the height and the width of the tank and is so shaped that the wall element  surfaces  extend  at  least predominantly not  in planes which extend perpendicularly to the direction of travel, to prevent fuel from impacting umimpededly against those  surfaces  perpendicularly  thereto.  Those  surfaces thus represent divisions in the fuel tank. The volume of the fuel between the wall element and the respective tank wall surface to be shielded is not sufficient to produce noises which are a nuisance when travel movements occur.
