  • Publication number: 20040205463
    Abstract: Improved apparatuses, programs, and methods for navigating summarized data are disclosed. Textual data is received, converted into hypertext markup language, and the converted data searched for operator selectable strings indicative of data items having a relatively higher level of import. Information extracted from the converted data is summarized in a report that includes a link from the summary to the location of the string in the converted data.

  • Patent number: 6467051
    Abstract: A system that can test individual components having tolerances on a circuit board without complete access to every node on the board is disclosed. The system uses a method that develops test limits from a model of the board, component tolerances, and a list of accessible nodes. A method of reducing the complexity of the test problem by limiting the number of components under consideration is also disclosed. A method of reducing the complexity of the test problem by limiting the number of nodes under consideration is also disclosed. A method of picking nodes to apply stimulus to a board is also disclosed. Finally, a method of correcting for certain parasitics associated with tester hardware is disclosed.

  • Patent number: 6334100
    Abstract: A method for evaluating and correcting a model of an electronic circuit. A list is created which comprises the minimum number of components that must be specified by the operator in order to be able to compute values for the remaining circuit components. Correction of circuit models can be performed even in cases of limited accessibility to the circuit's nodes.
