  • Publication number: 20020120431
    Abstract: A method of simulating a bio-transport system comprising: (a) characterizing one or more elements to represent a bio-transport system of an organism or a portion thereof; (b) constructing one or more mathematical representations that model one or more bio-transport dynamics for each element based on the characterization of the elements to form a configured simulation model; (c) initializing the configured simulation model; (d) executing the configured simulation model to obtain bio-transport dynamics data for one or more elements; and (e) outputting information to a user based on at least a portion of the bio-transport dynamics data.

  • Patent number: 6198420
    Abstract: A DC coupled serial data stream receiver system utilizing a switched capacitor based differencing front end which compares the instantaneous value of an analog voltage with respect to its long term minimum value to a series of reference voltages V1 to Vn in a flash analog to digital converter style front end. The circuit is designed to interface directly to a discrete fiberoptic preamplifier. The receiver can handle multiple amplitude serial data as produced by multiple fiberoptic transmitters on the same fiber without any data loss and without any interruption in data transfer being necessary as one transmitter halts and a second one starts transmission.

  • Patent number: 5737581
    Abstract: A process is disclosed for simulating on a computer system the implementation of a quality system on a business having a product flow. The process entails first inputting a selection of quality assurance measures of the quality system, and then configuring a quality model resident within the computer system according to the selection. This forms a configured quality model which has a mathematical relationship representing each quality assurance measure selected. Next, product flow data is generated representing the product flow having a number of defects. In the preferred embodiment, the selection of quality assurance measures affects the number of defects being introduced into the product flow. The product flow data may be generated within the computer system or by a source outside the system. The configured quality model is then applied to the product flow data, and the results of the quality assurance measures on the product flow are displayed on a user interface of the computer system.
