  • Patent number: 7185315
    Abstract: An apparatus, program product and method visually represent the disparities between a target design such as a DSP program design and a reference system in connection with the display of a graphical representation of the design, specifically in association with one or more connection elements representing connections defined within the target design. By doing so, a designer, developer or tester who is working with a particular target design is better able to identify and analyze potential problems or other unexpected and/or unintended behaviors in a target design.
    Type: Grant

  • Patent number: 6549858
    Abstract: A method and apparatus for decoupling complex multiple degree-of-freedom (MDOF) responses measured on linear dynamic systems into constituent single degree-of-freedom (SDOF) modal responses. A data acquisition and processing system periodically samples response signals generated by a plurality of sensors spaced at various locations on a linear dynamic system. The processing system calculates a plurality of sets of spatio-temporal filter coefficients based upon time-shifted digitized response signals. A synthesizer applies the spatio-temporal filter coefficients to the response signals, thereby generating synthesized signals representing decoupled SDOF responses of the linear dynamic system. Means are provided for receiving input signals representing a plurality of excitation inputs and for calculating input influence coefficients based upon the time-shifted digitized response signals and the excitation input signals.
