  • Patent number: 6788493
    Abstract: A disk drive includes a drive housing, one or more rotating storage disks, each having a storage surface, and a fluid diffuser. The fluid diffuser includes one or more stationary diffuser wings, each having a wing surface positioned near the storage surface. One or more of the diffuser wings can extend between two of the storage disks. The diffuser wing includes a surface deviation that disrupts the fluid flow over the wing surface that is caused by the rotating storage disk. The surface deviation can include an indentation in the wing surface or can extend from the wing surface toward the storage surface. In still another embodiment, the surface deviation includes an aperture that extends through the diffuser wing. Further, the fluid diffuser can include a plurality of surface deviations that are positioned along the wing surface. Further, a portion of the surface deviation can form an angle with the wing surface that is greater than approximately 0 degrees and less than approximately 180 degrees.

  • Publication number: 20020182607
    Abstract: The invention provides a method for determining a sequence boundary. The method includes the steps of (a) contacting a population of addressed fragments of eukaryotic genomic DNA with a target polynucleotide, the target polynucleotide binding a terminal sequence of a DNA region, the addressed fragments of eukaryotic genomic DNA being at least 100 nucleotides in length; (b) determining a relative order for 2 or more of the addressed fragments compared to a sequence of the genomic DNA; (c) identifying a pair of fragments among the 2 or more addressed fragments that alternatively bind the terminal sequence of a region; and (d) determining for the sequence of the genomic DNA a relative location of a boundary of the region compared to a location of at least one genomic DNA fragment in the pair.

  • Patent number: 5939286
    Abstract: The present invention describes hybrid interferon fusion polypeptides formed of a first segment that contains the N-terminal amino acid sequence of an interferon-tau polypeptide, and a second segment that contains the C-terminal amino acid sequence of a non-tau interferon type I polypeptide. The two segments are joined in the region of a mature interferon polypeptide between about residues 8 and 37. Also described are nucleic acid sequences encoding such interferon fusion polypeptides, expression vectors containing such sequences, and therapeutic applications of the interferon fusion polypeptides. The therapeutic applications include antiviral and anticellular proliferation applications. One advantage of the interferon fusion polypeptides of the present invention is that they do not have cytotoxic side-effects when used to treat cells.

  • Patent number: 5859972
    Abstract: A system and method for managing informatics in a specialty field, such as medicine, biology, and so on. A local workstation is connected to a server over a network. A user runs a browser application on the local workstation. A plurality of remote data repositories are accessible to the server. The informatics management system includes a gateway program running on the server. The gateway program receives a query request in a first format from the user over the network. The gateway program includes a query translator routine that translates the query request from the first format to a plurality of different formats. The translated query requests are sent to the remote data repositories and results are received therefrom. The gateway program includes a results translator routine that translates the results received from the remote data repositories into results in the first format and sends the results in the first format to the user's workstation.
