Patent number: 8607099Abstract: Data structure errors, or corruptions, identified during, e.g., normal computing device system processing, file system processing or user access processing, are verified prior to the file system identifying the error for offline correction or notifying the user or system administrator a data structure error exists. Identified data structure corruptions are verified while the file system volumes are maintained online and otherwise accessible to other processing tasks and user access. Verified data structure corruptions are logged for further corrective processing. Data structure corruptions that cannot be verified, i.e., false positives, are not further processed and are not identified to file system administrators or users as corruptions, freeing the file system to concentrate on normal processing and true, verifiable errors.Type: GrantFiled: December 17, 2010Date of Patent: December 10, 2013Assignee: Microsoft CorporationInventors: Sarosh C. Havewala, Neal R. Christiansen, John D. Slingwine, Craig A. Barkhouse, Daniel Chan

Publication number: 20120159256Abstract: Perceived corruptions encountered on file system volumes, and which cannot be initially remedied online, are processed to verify whether they are true, existing volume data structure corruptions or, alternatively, false positives. Upon the verification of one or more of a volume's corruptions, error scanning is performed to check for, and attempt to remedy online, all the existing corruptions on the volume. Subsequent to error scanning processing, if one or more verified corruptions continue to exist on a file system volume, at file system boot up time spot corruption correction is performed to attempt to remedy the existing, verified corruptions on the volume. Spot corruption correction is performed to attempt to correct verified data structure corruptions on a volume of the file system while the volume is maintained offline for the time necessary to attempt to correct its prior identified corruptions.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: Sarosh C.

Patent number: 8163073Abstract: An alkalescent chemical silver electroless plating solution, which comprises: 0.01˜20 g/L silver ion or silver complex ion, 0.1˜150 g/L amine complexing agent, 0.1˜150 g/L amino acids complexing agent, and 0.1˜150 g/L polyhydroxy acids complexing agent. The alkalescent chemical silver plating solution provided by the present invention is able to overcome problems existing in acidic chemical silver plating processes commonly used at present. These problems include gnawing and corrosion of copper wires, lateral corrosion and difficulty of plating silver in blind holes, presence of solder ball voids and low strength of soldering. The silver layer plated by said silver plating solution possesses characteristics of high corrosion resistance, low contact resistance, no electromigration, high welding strength, and avoidance of bubbles produced in the solder when the plating pieces are being welded.Type: GrantFiled: December 8, 2006Date of Patent: April 24, 2012Assignee: Chartermate International LimitedInventors: Kin Kwok Daniel Chan, Wing Hong Lai, Jing Li Fang

Publication number: 20120010562Abstract: An infusion system that includes a controller device and a communication system to provide for two-way communication between the controller device and an infusion device that controls delivery of fluids to a user's body. Either the controller device or the infusion device may be integrated with a characteristic determining device in a single housing. The housing, in turn, may include a test-strip receptacle and an illuminator disposed so as to illuminate an area covering the receptacle and a test-strip inserted therein. The illuminator may be configured to be activated automatically when a test strip is inserted into the receptacle, selectively by the user via a button, key, or similar mechanism, and/or when the ambient light level, measured, e.g., with a light sensor, falls below a predetermined intensity. The illuminator may be a LED emitting white light, and may provide illumination at various levels of intensity.Type: ApplicationFiled: September 20, 2011Publication date: January 12, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: MICHAEL A.

Publication number: 20100190556Abstract: Embodiments of the invention provide a computer-readable storage medium tangibly storing a game program for generating images in an object space viewed from a given viewpoint. The program causes a game system to function as an acceptance unit and a processing unit. The processing unit performs processing to create a severance plane, define a mesh structure for an object, determine whether the severance plane intersects the mesh structure, sever the object into multiple sub-objects, define mesh structures for the multiple sub-objects, and create and display caps for severed ends of the multiple sub-objects.Type: ApplicationFiled: January 26, 2010Publication date: July 29, 2010Inventor: Daniel Chan

Publication number: 20070281034Abstract: The invention provides for water-dispersible microparticles comprising magnetic material and organic substance, such as a pharmaceutical or a pigment, that constitute in totality at least 50%, or preferably more that 70%, of the dry mass of the particle. The method of making such microparticles is also provided, comprising coating of the magnetic material in an aqueous colloid form with a layer of a polyelectrolyte, and combining the coated colloid with the organic substance having ionic charge opposite to that of the polyelectrolyte. When the organic substance is poorly soluble in water, the combining comprises dissolving of the substance in a water-miscible organic solvent, and combining said solution with the polyelectrolyte-coated magnetic colloid. The magnetic pharmaceutical microparticles are useful for magnetically-guided drug delivery, and/or for non-invasive monitoring of the drug distribution in the body. Magnetic microparticles comprising dyes and pigments are useful in magnetic inks.Type: ApplicationFiled: May 15, 2007Publication date: December 6, 2007Inventors: Dmitri Kirpotin, Daniel Chan, Paul Bunn
