  • Patent number: 8271504
    Abstract: Systems and programs for improving the efficiency of a sorting process in a computer system are disclosed. Data is provided in an input file external to the central processing unit of the computer system. In one embodiment, the implemented process involves investigating the contents of the input file in order to identify presorted portions thereof; incorporating the identified presorted portions of the input file into a second file external to the central processing unit, performing this step by rearranging directory information, without physically transferring the presorted portions from the input file. In sort processes involving both a string generation phase and a merge phase, the techniques described may be used in either or both phases, as well as in any output phase. Rearrange directory information rather than physically transferring data provides for greater efficiency in disk I/O.

  • Patent number: 8187360
    Abstract: The present invention concerns a process for the instantaneous control of the precipitation of nickel and cobalt present in a leach liquor by adjustment of the pH-value. Said leach liquor is obtained by pressurized acidic leaching of laterite ores and additionally contains aluminium, ferric and ferrous iron and chromium among others. The process comprises the following steps: precipitation of aluminium, ferric and ferrous iron, chromium etc. by increasing the pH-value by adding a suitable reagent such as lime and/or limestone, following precipitation of nickel and cobalt by further increasing the pH-value of the liquor, finally separating the precipitate from the low-content nickel and cobalt solution. The nickel and cobalt precipitate can be used for further refinement. In order to keep the process conditions constant, the steps of increasing the pH-value are controlled simultaneously.

  • Patent number: 8161081
    Abstract: A software system automatically and dynamically generates a fully functional user interface (UI) based upon, and connected directly to, an underlying data model (as instantiated within a relational database management system (RDBMS)). The UI derives from an automated interrogation of the RDBMS, and comprises all mode displays (e.g., browse, search, edit, add) for all tables, and a full complement of mechanisms—integrated directly into the mode displays—for representing, navigating, and managing relationships across tables, regardless of the complexity of the underlying RDBMS schema. It utilizes a hierarchical “context stack” for suspending the working state of a particular table while “drilling down” to work with related-table information and return relevant changes to the base table.

  • Patent number: 8142018
    Abstract: Imaging apparatus and filters are provided for accurately imaging, assessing and measuring a patient's macular pigment. A multi-band filter is employed in combination with a color digital fundus camera to provide a method that operates with a single imaging exposure. The multiband filter has bandpass regions within spectral ranges of the red, green and blue detectors of the CCD array employed within the fundus camera, the bandpass regions being sufficiently sharply defined so as to avoid regions where the CCD detector responses spectrally overlap. This provides three discrete channels of grayscale data corresponding to the bandpass regions of the multiband filter, which can be used to calculate macular pigment topographically. Methods are also disclosed for calculating the optical density of the macular pigment and advantageously displaying the resulting data.

  • Patent number: 8001134
    Abstract: A method of externally sorting large files in a computer system is presented. The contents of the input file to be sorted are investigated in order to identify presorted portions thereof. The presorted portions of the input file as thus identified are incorporated as sorted strings into an external sortwork file, by rearranging directory information rather than physically transferring data. If merging is necessary, the data may then be merged by a procedure wherein blocks of sorted data to be merged are incorporated into an output (sortout) file, by rearranging directory information rather than physically transferring sorted blocks to the sortout file. As a result of the process, portions of sorted data incorporated into the sortout file may physically remain in external storage space allocated to the input file, and/or in external space allocated to sortwork, thereby eliminating or reducing reading and writing from disk during sort-merge processing.
