The control system can be structured to: generate an operational signature based on the sensor information, estimate whether a fault (e.g., a mechanical fault of the component and/or a performance fault of the engine system) exists based on the operational signature, determine an engine operating mode adjustment if the fault exists and output the engine operating mode adjustment to an output device. Systems and methods for increasing the accuracy by which faults are detected and/or predicted are also disclosed. The engine operating mode adjustment can be applied to protect engine system components from being undesirably damaged to faults.

  • Patent number: 9418289
    Abstract: A system and method for restricting the number of layout patterns by pattern identification, matching and classification, includes decomposing the pattern windows into a low frequency component and a high frequency component using a wavelet analysis for an integrated circuit layout having a plurality of pattern windows. Using the low frequency component as an approximation, a plurality of moments is computed for each pattern window. The pattern windows are classified using a distance computation for respective moments of the pattern windows by comparing the distance computation to an error value to determine similarities between the pattern windows.
