Patent number: 8128572Abstract: The present invention involves method and apparatus for analyzing measured signals that are modeled as containing primary and secondary portions. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, the present invention involves utilizing a transformation which evaluates a plurality of possible signal coefficients in order to find appropriate coefficients. Alternatively, the present invention involves using statistical functions or Fourier transform and windowing techniques to determine the coefficients relating to two measured signals. Use of this invention is described in particular detail with respect to blood oximetry measurements.Type: GrantFiled: November 24, 2008Date of Patent: March 6, 2012Assignee: Masimo CorporationInventors: Mohamed K. Diab, Esmaiel Kiani-Azarbayjany, Ibrahim M. Elfadel, Rex J. McCarthy, Walter M. Weber, Robert A. Smith
