Patent number: 6706480Abstract: A method of screening for nucleic acid sequence copy no. in a sample genetic material, the method including introducing a no. of different genetic probes to hybridize with the genetic sample. The probes are flanked by the same or substantially the same primer binding sites thereby enabling amplification of sample-bound probes using a single primer pair and thus the screening of different sequence copy nos. at the same time. Genetic alterations are known to underlie phenotype characteristics including disorders as idiopathic mental retardation and neoplasia.Type: GrantFiled: January 3, 2002Date of Patent: March 16, 2004Assignee: University of NottinghamInventor: John Anthony Armour

Patent number: 6658800Abstract: A method and structural component for use in constructing geodesic domes using standardized polygon panels. The invention allows for the use of a reduced number of components to construct a geodesic dome. In one embodiment, a set of kite-shaped quadrilateral panels with an external convex surface are used to substantially construct a geodesic dome. A panel includes two lip seal panel edges. The lip seam edge includes an inwardly disposed lip forming a mating surface suitable for mating with an adjacent straight seam edge of a corresponding panel so that the engagement between the two edges forms a seal. The seal may be made to impede moisture by various fastening methods, including screwing, riveting, gluing, taping or welding. Practice of the invention reduces transportation, inventory, and handling expense. Procurement, assembly, and maintenance complexity for the end user is also reduced.Type: GrantFiled: October 4, 2001Date of Patent: December 9, 2003Inventors: John A. Monson, James C. Monson

Patent number: 6643645Abstract: Retrofitting recommender systems, so that they can scale to large data, is disclosed. The principal notion is to reduce data requirements of existing recommender engines by performing a type of data reduction that minimizes the loss of information given the engine. The reductions covered in this invention are designed to be easily implemented on a database system, and are intended to have minimal impact on an existing implementation of a recommender system. In one embodiment, a method repeats reducing the data by a number of records, until an accuracy threshold or a performance requirement is met. If the accuracy threshold is met first, the method repeats removing a highest-frequency dimension from the data, until the performance requirement is also met. The reduced data is provided to the recommender system, which generates predictions based on the reduced data, and a query.Type: GrantFiled: February 8, 2000Date of Patent: November 4, 2003Assignee: Microsoft CorporationInventors: Usama M. Fayyad, Paul S. Bradley, Bassel Y. Ojjeh

Patent number: 6629031Abstract: A method of providing a vehicle monitoring system for ensuring accurate vehicle mileage readings. A comparison is made between velocity measurements from several sources to detect unauthorized modifications made to a vehicle in an effort to ensure accurate vehicle odometer readings. The vehicle velocity measured on-board is compared with vehicle velocity data signals received from a remote satellite system in light of an allowable tolerance. The system will detect changes in the vehicle such as tire size or tampering with the vehicles on-board measurement devices. The system may communicate out of tolerance conditions to the vehicle operator and the fleet manager.Type: GrantFiled: January 9, 2002Date of Patent: September 30, 2003Assignee: Volvo Trucks North America, Inc.Inventors: Tommy Gustavsson, Michael Blackard, John Bate, Brian Kidd

Patent number: 6615216Abstract: Method and apparatus for maintaining a queue structure having data nodes within a computer memory. The queue is maintained by the steps of maintaining a pool of available data nodes for use in maintaining the queue structure. Data is added to the queue structure by adding a nodes to the queue structure. Each data node includes a data portion, a link for addressing other data nodes in the queue structure, and an identifier. Data within the queue is accessed and then removed from the queue but the data nodes are preserved in memory by adding them to the pool of available data nodes. New data nodes are added to the queue by first checking the data pool, which in an exemplary embodiment is in the form of a stack, to determine if there are any nodes available in the pool before creating a new data node.Type: GrantFiled: June 29, 2000Date of Patent: September 2, 2003Assignee: Microsoft CorporationInventor: Carl Hu

Patent number: 6582891Abstract: A process for reducing roughness from a surface of a patterned photoresist. The process includes exposing a substrate having the patterned photoresist thereon to a vapor, wherein the vapor penetrates into and/or reacts with the surface of the photoresist.
