  • Patent number: 5729451
    Abstract: A data fusion workstation apparatus and method utilizes algorithms and can be used for applications such as, e.g., hydrogeological modeling, steady-state hydrological flow modeling, transport uncertainty determination, flow/transport fusion, oil reserve management, water supply development, geo-technical engineering projects, and management decision optimization. The invention uses a spatial continuity model which is extended to 3D and equations are provided for computation of the spatial AR coefficients from a desired covariance function. The data fusion workstation provides more robust optimization iterations by use of an algorithm that includes Trust Region or Step Halving methods to limit the Gauss Newton step in solving non-linear least squares problems. Measurement biases and error parameters, and parameters which define a hydrological flow model can be included in the common set of estimated states.

  • Patent number: 5046729
    Abstract: The apparatus of the invention comprises a backboard; a matrix of panels representing a strike zone; springs for resiliently biasing each of the panels outwardly from the backboard; switches mounted to the backboard behind the panels, whereby the impact of a pitched ball will move the panel inwardly towards the backboard causing the switch to momentarily close; a horizontal array of red, yellow and green lamps mounted to the backboard adjacent the top of the backboard, one lamp in vertical alignment with each of the columns of panels; a left vertical array of red, yellow and green lamps mounted to the backboard adjacent the left edge of the backboard, one lamp in horizontal alignment with each row of panels; a right vertical array of red, yellow and green lamps mounted to the backboard adjacent the right edge of the backboard, a power source; and electrical wiring to connect the power source, switches and lamps.
