Title: Three-dimensional skeleton data compression apparatus
Inventor: ARAI MASATOSHI
IPC: G06T13/40
Filed: 1998-12-28
Abstract: The present invention relates to a three-dimensional skeleton data compression apparatus for compressing a skeleton data amount without degrading rendering quality of a three-dimensional object. A weight detecting part detects weight information that is a numerical value obtained from input skeleton data, showing a degree of the influence of the movement of a skeleton on a vertex, and a weight compressing part deletes a value equal to or lower than a predetermined threshold value. The skeleton compressing part conducts first skeleton compression with respect to a skeleton having no polygon vertex in which an effective weight value is set. The skeleton compressing part also detects relative movement between skeletons, and second skeleton compression is performed to reduce/integrate a skeleton group integrated without relative movement into a unified skeleton. If required, masks are put on skeletons that are not to be subjected to skeleton compression. A polygon file is generated based on compression skeleton data, model information of a polygon and a texture, and scenario information.

Title: Electrochemical processing
Inventor: TURNER ANDREW DEREK
IPC: C25B9/19
Filed: 2001-12-13
Abstract: Using a solution mining procedure, an ore (10) is treated with a solution of acetic acid and hydrogen peroxide so as to form a leachate containing lead ions.  Lead ions (and other metal ions such as zinc and manganese) are stripped (22, 24, 26) by solvent extraction from the leachate to form separate aqueous solutions. The aqueous solution containing lead ions is treated electrochemically in the anodic compartment of a separated electrochemical cell (42) to form a precipitate of lead oxide. Manganese dioxide can be produced similarly (72). A precipitate of zinc hydroxide can be formed in the cathode compartment of a separated electrochemical cell (56). In the cells (42, 72) extracting lead ions and manganese ions, the cathode compartment is used to generate hydrogen peroxide (for use in making the leachant), either directly or indirectly.

Title: Self-jigging resilient construction member and retrofit system using same
Inventor: SMITH MARK H
IPC: E04B2/74
Filed: 2000-06-19
Abstract: A construction beam (100) includes a pair of lateral members (102, 104) and a resilient web (106) extending therebetween, so as to present a cross-sectional profile corresponding to commonly used construction beam members (for example, 2" x 4" or 2" x 6" (5.08 cm x 10.16 cm or 5.08 cm x 15.24)). The resilience of the web helps to attenuate sound transmission through the beam from one lateral member to the other. In particular, in a wall frame, the lateral members are mounted at opposite ends thereof to end plates consisting of other construction beams according to the present invention (that is, a pair of lateral members with a resilient web extending therebetween). When the wall frame is used in a building structure, the lateral members of the end plates on the same side are attached to the surrounding structure, leaving the other side of the frame resiliently free floating. A wall is mounted on the free floating side of the wall frame so as to provide a resiliently free floating wall that acts as a sound attenuating "diaphragmatic" absorber. The web is preferably (but not necessarily) provided with spacers (410) formed thereon, so that the lateral members can be easily oriented relative to the web and to each other, so as to be self-jigging. The spacers may conveniently be formed by cutting and bending tabs in the material of the web in desired locations.

IPC: G11B20/00
Filed: 2001-06-15
Abstract: An information processing system and method using an encryption key block sets sub-trees classified based on data processing ability of the devices (capability) in a key tree in which respective keys are corresponded to a root, nodes and leaves of a tree in which a plurality of devices are constituted as the leaves, generates a sub-enabling key block which is effective for an entity in a managing subject of each sub-tree (entity), and generates an enabling key block decodable only by the entities having common capability. Also, an information processing system and method using an encryption key block manages a partial tree of a key tree (sub-tree), generates a sub-enabling key block based only on a key set corresponding to nodes or leaves included in the sub-tree, and generates an enabling key block decodable only by selected entities by using the sub-enabling key block. Thus, it is possible to generate and distribute an enabling key block corresponding to data processing ability of a device and to manage devices by dividing a hierarchical key tree structure.

Inventor: WARRINER KEITH STEWART ROBERT
IPC: G01N27/40
Filed: 2000-07-12
Abstract: L'invention concerne des dispositifs de capteurs permettant d'analyser des échantillons fluidiques, à l'aide d'un capteur séparé des échantillons par une membrane perméable constituée d'un mélange d'un polymère imperméable (en particulier un polyvinylchloride (PVC)) avec un poly-vinylpyridine (PVP). Habituellement, la proportion de PVP est sensiblement de 20-80 % en poids des polymères combinés, et la membrane possède une épaisseur inférieure à 50 um. Cette membrane peut représenter 10 parts d'une membrane multicouche, et peut utiliser un enzyme pour transformer un analyte en un autre. Les procédés d'utilisation de ces dispositifs essentiellement électrochimiques, permettent d'effectuer des mesures ampérométriques à l'aide d'une électrode métallique (en particulier en platine). La perméabilité de la membrane aux analytes tels que le glucose est intéressante pour évaluer un milieu biologique, par exemple le sang. Le mélange polymère présente une résistance inhabituelle à l'encrassement permanent due aux matériaux de poids moléculaire élevé utilisés, ce qui permet de les laver lorsque nécessaire. La membrane peut être utilisée de manière répétée, cette propriété étant conférée aux autres surfaces par recouvrement par le mélange polymère.

Abstract: An improved, air tight valve seat (42) for a pneumatic brake system is achieved by using a plastic valve seat that is coined by the valve member (30). The valve member is a harder material, for example metal, than the thermo-plastic valve seat. The valve member is brought to an elevated temperature less than the melting point of the valve seat. The valve member engages the valve seat, coining the desired surface of the valve seat to conform it to the valve member. The heated valve member then remains in the valve assembly (10) after coining.
Patent CA-2384701-A1 (CA)
Inventor: WEERAWARNA S ANANDA
IPC: D06M13/322
Filed: 2000-10-06
Abstract: The invention is directed to a method of making carboxylated cellulose fibers whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of cyclic nitroxide free radical compounds as a primary oxidant and a hypohalite salt as a secondary oxidant in an aqueous environment. Preferably the oxidized cellulose is then stabilized against D.P loss in alkaline environments and color reversion with a reducing agent such as sodium borohydride. Alternatively it may be treated with an oxidant such as sodium chlorite. The method results in a high percentage of carboxyl groups located at the fiber surface. The product is especially useful as a papermaking fiber where it contributes strength and has a higher attraction for cationic additives. The product is also useful as an additive to recycled fiber to increase strength. The method can be used to improve properties of either virgin or recycled fiber. It does not require high .alpha.-cellulose fiber but is suitable for regular market pulps.
