  • Method and apparatus for online identification of safe operation and advance detection of unsafe operation of a system or process
    Patent number: 6826513
    Abstract: A method and apparatus for online identification of safe operation and advance detection of unsafe operation of systems or processes from signals containing noise wherein the method and apparatus uses wavelet transformations to accurately infer from criteria about the changes in the monitored process variables and its acceleration as a basis for advance detection of unsafe operation, the said process of online identification of safe operation and advance detection of unsafe operation has applications in a wide variety of situations where digitized data could be made available.
    Type: Grant
    Filed: August 13, 2003
    Date of Patent: November 30, 2004
    Assignee: Council of Scientific & Industrial Research
    Inventors: Viruthiamparambath Ravi Kumar, Bhaskar Dattatraya Kulkarni, Anandamohan Ghosh
  • Method and an apparatus for the identification and/or separation of complex composite signals into its deterministic and noisy components
    Patent number: 6208951
    Abstract: A process for the identification and/or separation of composite signal into its deterministic and noisy components wherein the process uses recursive wavelet transformations to separate the deterministic and noisy components of signals and uses the difference in the properties with regard to degree of correlation and dimensionality of these constituent components as a basis for separation, the said process of identification and/or separation has application in a variety of situations where digitized data is made available via an apparatus which converts the monitored signals.
