Abstract: An estimation section calculates the motion vector of each pixel and its reliability from two continuous frames, and generates first-order motion distribution images corresponding to the k-th and (k+ 1)-th frames with any motion vector and reliability being assigned to each pixel. An update section combines the input first-order motion distribution image corresponding to the (k + 1)-th frame and the fourth-order motion distribution image corresponding to the (k + 1)-th frame generated from the first-order motion distribution image corresponding to the k-th image to generate the second-order motion distribution image corresponding to the (k + 1)-th frame. A prediction section generates the third-order motion distribution image corresponding to the (k + 2)-th frame according to the input second-order motion distribution image corresponding to the (k + 1)-th frame. An interpolation section interpolates into a blank space of the third-order motion distribution image corresponding to the (k + 2)-th frame with the use of unbiased estimate to generate the fourth-order motion distribution image corresponding to the (k + 2)-th frame.

Abstract: Cette invention concerne un système permettant d'améliorer l'efficacité du transfert d'énergie percutané. Ce système comprend une bobine émettrice (20) qui est appliquée sur la surface externe de la couche cutanée (24) du corps d'un patient à l'aide d'une bande adhésive ou de toute autre matériau de support approprié. Ce système comprend également un bobine réceptrice (22) qui est implantée dans le corps du patient. La bobine émettrice et la bobine réceptrice comprennent des noyaux (28, 42) qui possèdent des faces polaires (26a, 26b, 40a, 40b) dont la surface est sensiblement plus importante que la section transversale desdits noyaux en d'autres endroits. Le noyau de la bobine réceptrice (42) est en outre sensiblement plus court que celui de la bobine émettrice (28). Les lignes du flux (54) produites par la bobine émettrice ont ainsi tendance à passer à travers les faces polaires (40a, 40b) de la bobine réceptrice selon une densité plus élevée qu'elles ne le feraient si les faces polaires des noyaux émetteur et récepteur étaient espacées de manière identique. Le noyau émetteur (28) définit ainsi une partie inclinée à proximité de chacune des faces polaires, ceci de manière à ce que la partie principale dudit noyau (28) soit globalement parallèle à la surface de la couche cutanée (24) sur laquelle est placé le noyau émetteur (28), et à ce que cette partie soit à proximité de ladite surface.

Granted: 2006-05-30
Abstract: A weatherproof protector module for telecommunication circuits has wire insertion points that are arranged in lateral, forward and rearward symmetry about a single stuffer screw. The module contains J-shaped insulation displacement connectors (IDCs) with slits for engaging the wires. The symmetry of the module allows the screw to exert balanced forces in every direction as the wires engage the IDCs. The module also contains an insulative gel that is extruded around the wire contact locations when the wires are engaged. A wiper seal located each wire insertion point and a thixotropic gel prevent the expulsion of the insulative gel from the module after extrusion.

Granted: 2006-05-09
Abstract: An advance notification system (10) notifies users of the impending arrival of a vehicle, for example, an overnight package delivery vehicle, at a particular vehicle stop. The system generally includes an on-board vehicle control unit VCU (12) for each vehicle and a base state control unit BSCU (14) for sending messages to user computers (29) in order to inform the users when the vehicle resides at a certain predefined time period, distance, prior stop, location point from the vehicle stop. Moreover, the BSCU, a computer network, and software located on a user computer may be combined in a plurality of configurations for communicating a message of the impending arrival of a particular vehicle before it arrives. Each vehicle control unit VCU (12) includes a microprocessor controller (16). The VCU sends vehicle location and/or stop information to the BSCU. The BSCU compares the vehicle route stop list with route management software, then determines when to send an impending arrival message by the system operator.

Le corps de clapet (15) et les soufflets (80) définissent une chambre extensible reliée par un point de connexion inférieur ou ligne d'extension (97) au circuit d'évacuation (12). Si les eaux usées reculent, l'air se trouvant dans la chambre à fluide fait se dilater les soufflets (80) vers le haut pour fermer le clapet (45). Lorsque les eaux usées s'écoulent depuis le circuit d'évacuation (12), les soufflets (80) se déplacent vers le bas du fait de la différence de pression et la plaque supérieure (102) fait automatiquement revenir la lame du clapet (45) en position ouverte.

Abstract: Multiplexing and demultiplexing single-mode fiber optic couplers are fabricated by aligning two single-mode fibers which have been stripped of their protective plastic jackets and cleaned so that they are held in parallel contact with each other, and then fusing these fibers to achieve a desired fusion profile and elongating the fused fibers to achieve a match point between the wavelength period and the polarization phase. The elongation process is interrupted and resumed as required to obtain a precise match point required to produce the desired multiplexing or demultiplexing coupler.

Title: Moisture insensitive electroluminescent phosphor
Inventor: GINGERICH RICHARD G W
IPC: C09K11/56
Filed: 2000-08-24
Granted: 2011-03-15
Abstract: A phosphor particle has thereon a moisture resistant treatment of a metallic nitride. By moisture resistant is meant a condition allowing the phosphor particle to function in a humid atmosphere for a significantly longer period of time than an untreated particle.  The method of making such phosphors comprises the steps of introducing an inert gas into a reaction vessel; charging phosphor particles into the reaction vessel;  heating the reaction vessel to a reaction temperature; introducing a nitride coating precursor into the reaction vessel in a manner to avoid restrictive reactions; introducing a co-reactant into the reaction vessel; and maintaining the inert gas flow, co-reactant flow and precursor supply for a time sufficient to moisture-proof the phosphor particles. The nitride treated phosphor particles produced by this method, which can include the deposition of a nitride coating on the particles, have excellent efficacy ratings and strong luminance values in lamps after 100 hours use in high humidity (i.e., >95%). By avoiding restrictive reactions the method and apparatus can be used to manufacture commercial quantities of coated phosphors.

Title: Dispersion of fine porous inorganic oxide particles and processes for preparing same
Inventor: CHAPMAN DAVID MONROE
IPC: C01B13/14
Filed: 1999-07-07
Granted: 2009-09-08
Abstract: A dispersion comprising fine porous inorganic oxide particles, e.g., silica gel particles, wherein the particles have a median particle size below three microns. The dispersed particles have a porosity after drying in which at least about 0.50 cc/g of pore volume is from pores having a pore size of 600 .ANG. or less as determined by nitrogen porosimetry. Embodiments prepared from silica gel have porosity after drying in which at least about 0.7 cc/g of pore volume is from pores having a diameter of 600 .ANG. or smaller. The particles of the dispersion also can be described as having viscosity derived pore volume of at least about 0.5 cc/g. The dispersion is prepared by forming a dispersion from inorganic oxides having sufficient rigid structure to maintain porosity after milling and drying. After the inorganic oxide is selected, it is milled to have a median particle size of 0.05 to about 3 microns. In embodiments in which stable dispersions of fine porous particles are desired without the addition of substantial amounts of dispersant, or if dispersions having a median particle size less than one micron are desired, the dispersion is created by, for example, centrifuging the milled slurry to obtain a settled phase and a supernatant phase in which the median particle size is in the range of 0.05 to about 1 micron. The supernatant phase is then separated from the settled phase to create the final product.
