Patent CA-2439233-A1 (CA)
Inventor: MORRIS JAMES E
IPC: G02B3/00
Filed: 2001-06-22
Abstract: An array of micro-optical components (10) includes at least two micro-optical components. Each micro-optical component includes a refractive surface (12) and a corresponding compensation surface (22, 24) for the refractive surface (12). The corresponding compensation surface includes a corresponding compensation feature when the refractive surface deviates from a desired optical performance. The micro-optical component provides the desired optical performance. At least two refractive surfaces of the array of micro-optical components are formed to have substantially a same desired optical performance. The array of micro-optical components includes at least one corresponding compensation feature, at least two compensation surfaces of the array of micro-optical components being different from one another.

Title: System and method for removing dissolved gas from a solution
Inventor: CASTELLANO THOMAS P
IPC: A61M5/31
Filed: 2001-03-14
Abstract: Systems and methods are described for removing dissolved gases from a liquid either prior to or following filling into a container. Prior to filling, gas is removed by creating a pressure differential, by application of heat, by sonication, or by generating a liquid by combination of dry solute and de-gassed solvent. Alternatively, liquids may be highly concentrated with solute to force dissolved gas out of solution and later diluted with de-gassed solvents. In other embodiments, gases are percolated into liquids to displace atmospheric gases, wherein these percolated gases separate from solution and diffuse out of sealed containers after filling, either by nature of their molecular size or by chemical reaction with materials constructed into the container.

Title: Microcoil vaso-occlusive device with multi-axis secondary configuration
Inventor: COX BRIAN J
IPC: A61B17/12
Filed: 2001-11-07
Abstract: A vaso-occlusive device (10) includes a microcoil (12) formed into a minimum energy state secondary configuration comprising a plurality of curved segments (14a,14b,24), each defining a discrete axis (16), whereby the device, in its minimum energy state configuration, defines multiple axes. In a preferred embodiment, the minimum energy state secondary configuration comprises a plurality of tangentially-interconnected, substantially circular loops (14a,14b) defining a plurality of discrete axes (16). In an alternative embodiment, the minimum energy state secondary configuration defines a wave-form like structure comprising a longitudinal array of laterally-alternating open loops (24) defining a plurality of separate axes (16). In either embodiment, the device (10), in its minimum energy state secondary configuration, has a dimension that is substantially larger than the largest dimension of the vascular site in which the device is to be deployed. Thus, when the device (10) is deployed in an aneurysm (40) , the confinement of the device (10) within the aneurysm (40) causes the device (10) to assume a three-dimensional configuration that has a higher energy state than the minimum energy state.

Patent CA-2471916-A1 (CA)
Title: Modified bacterial surface layer proteins
Inventor: SMIT EGBERT
IPC: C12N15/09
Filed: 2002-12-23
Abstract: Modified bacterial surface layer (S-layer) proteins are disclosed where the modification is the insertion, at an internal location, of a heterologous polypeptide, or polypeptide of interest. The polypeptide is a binding or target protein, such as an antigen or antibody, or part thereof, in particular a bacterial antigen (e.g. from Clostridium tetani such as TTFC). The modified surface layer protein can then be expressed on the surface of the bacterial cell and used in a vaccine. Also disclosed are bacteria which have been modified to express a heterologous surface layer protein, but which do not as a wild-type possess an S-layer (such as L. casei), and modified bacteria which express only a modified surface layer protein (and not the wild-type S-layer protein). The wild type S-layer is completely replaced with the modified version where the polynucleotide encoding the modified version is integrated into the bacterial genome. The modified S-proteins can form crystalline arrays, sheets or layers that can be used to bind functional molecules (e.g.  receptors) to solid surfaces (Au, silicon wafers) in biosensors.

Title: Method of removing pericarp from grain in recoverable form
Inventor: BROVOLD SANDRA L
IPC: A23L7/104
Filed: 2004-06-25
Abstract: A method for debranning grain, such as corn, involves treating the grain with hot water, followed by (1) treating the grain with an aqueous solution of a strong base and (2) detaching pericarp from the grain. Ethanol may be produced by hydrolyzing debranned grain produced by this method to sugars, and fermenting the sugars to ethanol. Alternatively, chemically or enzymatically modifying grain involves treating the grain with water to create a permeability barrier in the endosperm of the grain, and chemically or enzymatically modifying the portion of the grain outside the permeability barrier.

Title: Getpage - workload based index optimizer
Inventor: KLOSTERHALFEN JORG
IPC: G06F17/30
Filed: 2003-02-28
Abstract: The index optimization (XOP) program is a method to recommend new or improved performance indexes for use by an IBM mainframe DB2 database server for a given set of SQL statements. The recommendations are calculated based on a single call of the DB2 optimizer for each SQL statement with the existing index set, parsing of the SQL statements, the filter factors of the SQL  statement predicates, and the getpage workload of an SQL statement. The getpage workload of an SQL statement is the read/change activity on each table and each index currently used for all invocations of an SQL statement. The XOP  program computes new and improved performance indexes based on the getpage workload of all relevant SQL statements and does not use the DB2 optimizer to determine the usefulness of potential indexes.
