  • Patent number: 11567925
    Abstract: Aspects of the present disclosure relate to managing concurrent updates on data. A transactional update on at least one record within a data set is detected. A log is generated for the transactional update, the log including an image of the at least one record within the data set before the transactional update. A batch update is detected. A determination is made whether the batch update collides with the transactional update by referencing the log. In response to determining that the batch update collides with the transactional update, a collision policy is referenced. A collision action indicated in the collision policy is then issued.
    Type: Grant

  • Patent number: 7401061
    Abstract: An attribute engine matches incoming data against one or more matching attributes to set one or more target attributes of one or more rules. Each rule is characterized by a rule shape and a matchset. A template is defined for each rule shape and target attribute. Templates associated with a target attribute are sorted according to their matchsets and may be suppressed by one or more rule suppression principles. A rules editor is provided that allows support personnel to edit rules in tabular form instead of directly editing pseudo-code segments.

  • Patent number: 6759009
    Abstract: A self-contained analyzer quantitatively detects a clotting event in a biological fluid. The device includes a base having an open reservoir for receiving the biological fluid. A carrier for a dried activator reagent is located in or adjacent to the open reservoir. The biological fluid reconstitutes the dried reagent and starts the clotting process. During the clotting process the fluid travels through a capillary flow channel lined with a precision woven fabric. When clotting is completed, the woven fabric stops the flow of the fluid. A colored bar formed by the fluid flowing through the capillary channel indicates the length of time required for clotting of the sample.

  • Patent number: 6709868
    Abstract: A method for quantitatively measuring white blood cell count involves capture of white blood cells from a fluid sample by a retainer, removal of the red blood cells and other interfering substances by a wash solution, and reading the result of a color reaction in which an ester which is present on the white blood cells cleaves a chromogenic substrate which produces a water insoluble dye. The apparatus for use in the present method includes a retainer for white blood cells that has a dye substrate immobilized therein and an absorption layer that wicks and takes up all excess washing solution flowing past the sample.

  • Patent number: 5914271
    Abstract: The fertile period in a female can be detected by monitoring the calcium and magnesium concentrations in unstimulated saliva. In the three to five day period immediately prior to ovulation, the calcium and magnesium concentrations of saliva drop. This concentration monitoring can be done by any conventional means for quantitatively assaying calcium or magnesium, such as by flow through tests, test strips, cards, charts, probes, meters, and the like.

  • Patent number: 5794041
    Abstract: Alternatives for laying out objects and/or virtual function tables (VFTs), sharing a virtual function table pointer with a direct, virtual base, eliminating the need for an early cast by increasing the number of virtual function table entries, and providing a smart virtual dispatch that eliminates late casts where possible. An object model can be constructed by choosing one option from each of several alternatives. Interaction of alternatives include (1) sharing VFT pointers with a direct, virtual base requires that virtual base pointers are not stored in objects and (2) sharing VFT pointers affects the sharing of virtual base pointers with base classes and placement of late cast adjustment arguments and determining virtual function table entries.

  • Patent number: 5766552
    Abstract: Red blood cells are removed from whole blood or a fraction thereof by agglutinating whole blood with a mixture of a free agglutinating agent and nucleating particles having agglutinating agent intimately associated therewith to form clusters of red blood cells. High molecular weight polyethylene glycol may be added further to enhance agglutination. The clusters of red blood cells are much larger than the size of individual red blood cells, so that the clusters can easily be filtered through a porous medium. The plasma, which is substantially free of red blood cells, is further passed through a filter that optionally contains an additional agglutinating agent. Flow-delay additives may be provided to retain the fluid sample in contact with a reagent for a predetermined time.
