  • Patent number: 6192477
    Abstract: A method for performing secure communication between a first user's computer and second remote computer over a computer network is described. According to one embodiment of this aspect, the data space of the first computer is partition into a first secure portion and a second network interface portion. Communication is established between the first and a second computer, and redirection and filter mechanisms are initialized. An instruction is received by the first computer, analyzed by the redirection mechanism, and passed to the filter if the instruction is a protected instruction. The protected instruction is verified by the filter and processed if the verification is successful.

  • Patent number: 6188969
    Abstract: A computer-implemented statistical technique is provided for normalizing the response curves of multiple measurement methods. The end result is a group of response curves, one for each measurement method under consideration, which depend on a common independent variable—the actual physical property being measured by the methods. The results are provided as a collection of equations, curves, and/or tables (a “nomogram”) to facilitate conversion of measured values from one method to measured values from a second method. In the technique, data is provided for each of the methods being normalized. The input data includes measured values from common samples which are analyzed by two or more of the methods under consideration. The technique also requires assumptions or approximations of the true physical property values for each of the samples used to generate the data. Still further, the technique requires assumptions of the mathematical form of the response curves (e.g., linear, sigmoidal, etc.

  • Patent number: 6097831
    Abstract: Methods and systems for verifying the volume of a reagent dispensed into an affinity assay vessel are described. In one embodiment, a method is for verifying the volume of a reagent dispensed into an affinity assay vessel described in which a fluid sample is deposited into a vessel that includes a reaction chamber and a volume determination reference point. The reaction chamber further includes a test strip. According to one embodiment, the dispensed fluid is agitated to promote contact between the fluid and a test strip disposed within the reaction chamber. The relative positions of the volume determination reference point and an edge of the meniscus of the dispensed fluid are then determined such that the meniscus of the dispensed fluid is not penetrated. The volume of the dispensed fluid is determined from these relative positions.

  • Patent number: 6044218
    Abstract: A system for a live applet or application development environment includes software that cooperatively promotes and permits immediate socialization of new components with existing components as the new components are instantiated or dropped onto the development desktop. This is achieved by registering a new component being instantiated with the development environment's kernel. Registration, in turn, invokes an initialization method derived from the class template that yielded the new component. The initialization method appropriately personalizes the new component when it executes its associated logic. The initialization method provide an editor for the new component if its properties are to be made editable. The software environment, its kernel, templates, components, editor and methods are preferably programmed in the Java programming language or a Java compatible language.
