  • Patent number: 6706480
    Abstract: 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.

  • Patent number: 6648092
    Abstract: A Hall effect safety switch assembly for de-activating a motor vehicle if a user is not positioned on a vehicle seat. The assembly includes a switch frame for mounting the assembly, a magnet and a hall effect sensor mounted to the switch frame in a spaced apart relationship, and a vane that moves in response to the presence of a vehicle operator on the seat that causes the Hall effect sensor to provide an inhibit signal that prevents an engine from running.

  • Patent number: 6643645
    Abstract: 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.

  • Patent number: 6629031
    Abstract: 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.

  • Patent number: 6618926
    Abstract: A system for fabricating muntin bars from sheet material. Sheet material in the form of thin ribbon stock is fed to a first forming station including a punching mechanism that punches the ribbon stock at a precisely predetermined location. The ribbon stock is delivered from the first forming station to a second forming station in the form of a rolling mill. The stock passes through a succession of forming rolls to produce a tube having a desired cross-sectional shape. The tube is delivered from the second forming station to a third forming station including a severing apparatus that severs the tube at a precisely predetermined location to produce a muntin bar. After severing, the muntin bar is engaged by a conveyor and moved to a desired location.

  • Patent number: 6615216
    Abstract: 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.

  • Patent number: 6591440
    Abstract: A vacuum cleaner brushroll having skirted, one piece plastic ferrules inserted into the ends of a tufted, wood spindle so that the ferrule skirts embrace the spindle end portions to prevent the ferrules from loosening upon expansion of the spindle due to moisture. The skirts are drilled to permit angled tufting to be inserted very near the spindle ends with the tufting extending axially and radially outwardly beyond the spindle ends to provide improved edge cleaning and create a wider cleaning path compared to conventional brushroll designs.

  • Patent number: 6582891
    Abstract: 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. The substrate having the patterned photoresist thereon is then heated to a temperature and for a time sufficient to cause the surface of the photoresist to flow and/or react with the vapor wherein the surface roughness decreases. Optionally, the substrate is exposed to radiation during the process to increase the etch resistance of the photoresist and/or facilitate the reaction of the vapor with the surface of the photoresist.
