  • Publication number: 20210270828
    Abstract: The present invention provides a method for attaching cells to a biosensor surface (5) of a biosensor (4) comprising: providing a cell suspension in a liquid receiving unit (1), wherein the cell suspension forms a surface (7) to the exterior of the liquid receiving unit (1); contacting the biosensor surface (5) with the surface (7) of the cell suspension in the liquid receiving unit (1); and allowing the cells to settle on the biosensor surface (5) by gravity, and allowing the cells to adhere to the biosensor surface (5).

  • Patent number: 9286865
    Abstract: The present invention provides an assembly and method for playing music, whereby the assembly includes a bow spline, string stretched with tension along a portion of said spline, a frame having an apex, said frame positioned between said spline and said string, at least one string retaining member disposed on said apex, and a lower frame portion configured to contact said spline.

  • Patent number: 7720878
    Abstract: An improved data compression method and apparatus is provided, particularly with regard to the compression of data in tabular form such as database records. The present invention achieves improved compression ratios by utilizing metadata to transform the data in a manner that optimizes known compression techniques. In one embodiment of the invention, a schema is generated which is utilized to reorder and partition the data into low entropy and high entropy portions which are separately compressed by conventional compression methods. The high entropy portion is further reordered and partitioned to take advantage of row and column dependencies in the data. The present invention enables not only much greater compression ratios but increased speed than is achieved by compressing the untransformed data.

  • Patent number: 7627691
    Abstract: A method for clustering together network IP addresses is disclosed. A number of IP addresses are received and processed to determine which IP addresses share a longest prefix matching. The longest prefix matching process is performed according to radix encoded trie which facilitates on-line clustering of the IP addresses. Client and/or server IP addresses may be clustered in accordance with the teachings herein.

  • Patent number: 7191168
    Abstract: The present invention increases the efficiency of performing longest prefix matching operations by selecting a radix-encoded trie structure optimized with respect to memory cost. The structure is optimized by determining memory costs for retrie structures indexed on different numbers of high-order characters, and then selecting the structure corresponding to the lowest memory cost. The optimization improves performance in IP look-up operations as well as longest-prefix matching operations performed on general alphabets.

  • Patent number: 5978829
    Abstract: The present invention relates to systems for sharing idle workstation computers that are connected together through a network and shared file system. More particularly, a user of a local host workstation may submit jobs for execution on remote workstations. The systems of the present invention select a remote host that is idle in accordance with a decentralized scheduling scheme and then continuously monitor the activity of the remote host on which the job is executing. If the system detects certain activity on the remote host by one of the remote host's primary users, the execution of the job is immediately suspended to prevent inconvenience to the primary users. The system also suspends job execution if the remote host's load average gets too high. Either way, the suspended job is migrated by selecting another idle remote workstation to resume execution of the suspended job (from the point in time at which the last checkpoint occurred).

  • Patent number: 5806062
    Abstract: A data processing apparatus and method for creating data analysis applications using reusable software operators . An initial operator is provided for converting source information into a virtual database format. Query operators are provided for receiving data in a virtual database format, processing the data in the virtual database, and outputting the results of the processing in another virtual database which has the same schema as the received virtual database. A plurality of query operators may be combined in order to customize the processing of the virtual database data. A terminal operator is provided for converting data in a virtual database into an external format which may then be further processed by an external operator. By combining initial, query, terminal, and external operators, users may create customizable data processing applications. In accordance with one embodiment of the invention, operators are provided for analyzing the difference between a first document and a second document.
