Patent CA-2409556-A1 (CA)
Inventor: ANIKINA ELENA
IPC: A61F9/00
Filed: 2002-10-23
Abstract: The present invention provides ophthalmic methods and apparatus for low-level light therapy of various eye diseases connected with accommodative dysfunctions and functional disorders of parts of the visual system from and including the retina to the brain. One of the treatment methods of the present invention provides a healing influence with a laser speckle pattern or regular interference pattern applied to the visual system resulting in, for example, visual acuity enhancement in the case of functional amblyopia. Another treatment method provides both a functional influence by the application of a laser speckle pattern onto the visual system and the transscleral biostimulation of eye tissues by means of infrared irradiation of one or more areas of the eye sclera.      The infrared biostimulation of eye tissues results in the improvement of eye muscle capability and enhances eye blood circulation. The present invention provides further an ophthalmic therapy system and ophthalmic binocular units for use with the above therapy method.

Title: Seal ring and method of forming micro-topography ring surfaces with a laser
Inventor: YOUNG LIONEL A
IPC: F16J15/34
Filed: 2001-07-05
Abstract: A seal ring (10) of a shaft seal has micro-topography depth features (22), such as wavy faces or radial grooves, formed in the seal face which define a hydrodynamic seal region between opposing seal faces. The micro-topography depth features are formed by an excimer laser (59) shaped such that the beam shape at least has non-linear side edges which define convergent side areas of the beam. The convergent side areas are defined by side edge sections which converge toward each other and preferably are non-linear. The laser beam first cuts repeatedly along the same beam path to define multiple adjacent beam cuts that form the micro-topography feature such as a valley of a wavy face, a radial groove or the like. As the laser beam cuts adjacent parallel grooves, sidewardly adjacent beam passes overlap one with each other and blend the edges of the sidewardly adjacent groove together. The method of the invention provides micro-topography depth features that are precisely and accurately defined to improve performance of the seal ring.

Title: Method and apparatus for selecting maximally disjoint shortest paths in a network
Inventor: NEUSTADTER UDO MIRCEA
IPC: H04L12/56
Filed: 2003-01-30
Abstract: A method for selecting two maximally disjoint shortest paths between a source node and destination node in a network is provided. The method comprises determining a first explicit route between the source and destination nodes by using an original link cost for each link in the network, transforming the network by introducing conditional link coast, determining a second explicit route between the source and destination nodes in the transformed network taking into account the conditional link costs, and determining the two maximally disjoint shortest paths between the source and destination nodes by coalescing the first and second explicit routes. Beneficially, the step of introducing conditional link costs comprises adding additional parameters to links in the network and determining the conditional link costs depending on the position of each link relative to the first explicit route. Corresponding method for determining "N" maximally disjoint paths in a network, wherein "N" is equal or greater than two, is also provided.

Abstract: A tibia fixturing device comprises a metal tray formed with annularly spaced recesses in its underside at a depth of at least about 1.5 mm and from which a stem depends for axial insertion into a tibia conical cavity. The stem has a circular cylindrical portion proximal the tray and a conical portion distal the tray. Fins radially extend from the stem cylindrical portion and penetrate the tibia to provide some torsional resistance. Axially extending channels are formed about the stem periphery which channels have bottom surfaces parallel to the stem axis to provide further torsional resistance. The channels are arranged to not interlock with the cement in the axial direction to permit the cement to separate first from the device during axial removal of the device from the bone. The fins have inclined edges distal the tray and inclined radial outer edges to align and center the stem to the bone cavity edge. Cement in the tray recesses bonds the tray to a tibia resected surface to provide major torsional resistance of the tray about the cavity longitudinal axis.
