  • Patent number: 7144592
    Abstract: A method of making a fully hop flavored beverage employs a hop flavoring agent comprising an extract of hop solids, the hop solids being the residue of a first extraction of hops to remove the alpha acids. Preferably, liquid carbon dioxide is used for the first extraction of the hops and a polar solvent, such as ethanol or water, is used to extract the hop solids. Beverages made by the method and novel compositions for use in the method are also disclosed.

  • Publication number: 20060015262
    Abstract: A method and system for automated quantitation of tissue micro-array image (TMA) digital analysis. The method and system automatically analyze a digital image of a TMA with plural TMA cores created using a needle to biopsy or other techniques to create standard histologic sections and placing the resulting needle cores into TMA. The automated analysis allows a medical conclusion such as a medical diagnosis or medical prognosis (e.g., for a human cancer) to be automatically determined. The method and system provides reliable automatic TMA core gridding and automated TMA core boundary detection including detection of overlapping or touching TMA cores on a grid.

  • Publication number: 20050266395
    Abstract: A method and system for morphology based mitosis identification and classification of digital images. Luminance parameters such as intensity, etc. from a digital image of a biological sample (e.g., tissue cells) to which a chemical compound (e.g., a marker dye) has been applied are analyzed and corrected if necessary. Morphological parameters (e.g., size, elongation ratio, parallelism, boundary roughness, convex hull shape, etc.) from individual components within the biological sample are analyzed. A medical conclusion (e.g., type and count of mitotic cells) or a life science and biotechnology experiment conclusion is determined from the analyzed luminance and morphological parameters. The method and system may be used to develop applications for automatically obtaining a medical diagnosis (e.g., a carcinoma diagnosis).

  • Publication number: 20050265588
    Abstract: A method and system for automated digital fluorescent in situ hybridization (FISH) image analysis. Luminance parameters from a digital image of a biological tissue sample to which a fluorescent compound (e.g., LSI-HER-2/neu and CEP-17 dyes) have been applied are analyzed to determine plural regions of interest. Fluorescent color signals in the plural regions of interest including plural cell nuclei are identified, classified and grouped into plural groups. Each of the plural groups is validated based on pre-defined conditions. A medical diagnosis or prognosis or medical, life science or biotechnology experiment conclusion determined using a count of plural ratios of validated fluorescent color signals within each of the cell nuclei within the plural groups.

  • Publication number: 20050136549
    Abstract: A method and system for automatically determining diagnostic saliency of digital images for medical and/or pathological purposes. Luminance parameters (e.g. intensity, etc.) from a digital image of a biological sample (e.g., tissue cells) to which a chemical compound (e.g., a marker dye) has been applied are automatically analyzed and automatically corrected if necessary. Morphological parameters (e.g., cell membrane, cell nucleus, mitotic cells, etc.) from individual components within the biological sample are automatically analyzed on the digital image. A medical conclusion (e.g., a medical diagnosis or prognosis) is automatically determined from the analyzed luminance and morphological parameters.

  • Patent number: 6898034
    Abstract: A method of measuring fly height of a read/write head to form a fly height profile for use in measuring fly height of the read/write head relative to a disc of a disc drive. A fixed source write signal is applied to an inductive element of the read/write head, generating a magnetic flux field with a stray magnetic flux field portion. A magnetoresistive element of the read/write head couples with the magnetic flux field producing an initial field strength signal. As the disc rotates, the read/write head flies there above decreasing the density of the stray magnetic flux field portion thereby decreasing the amplitude of the field strength signal. The decreasing amplitude of the field strength signal is calibrated to a predetermined operating fly height profile to correlate fly height of the read/write head to the decreasing amplitude of the field strength field, which forms the fly height profile.

  • Publication number: 20050105422
    Abstract: An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device.

  • Patent number: 6710964
    Abstract: The present invention is directed to a ramp load disc drive storage system having improved loading performance and a reduced likelihood of failure due to stiction and damage caused by contact between a slider and a disc surface during ramp load operations. The slider generally includes wear-resistive pads which allow for improved loading performance and reduce stiction between the slider and a disc surface. The pads also allow the ramp load disc drive storage system to be operated in a ramp load/unload mode or a contact start/stop mode. Additionally, a method of operating a ramp load disc drive is provided where the slider is loaded above a disc surface from a ramp prior to the disc reaching a full operating speed.
