  • Blind adaptive filter extraction of fetal electrocardiogram signal estimate
    Patent number: 7747316
    Abstract: A blind adaptive filter of an apparatus in an example employs a frequency domain ECG-feature vector and a time domain ECG feature vector with a maternal ECG parameter estimate and a set of candidate fetal ECG estimates that satisfy the frequency domain ECG-feature-vector, to extract a fetal ECG signal estimate from raw abdominal ECG signals of a pregnant female. The fetal ECG signal estimate satisfies the frequency domain ECG feature-vector and the time domain ECG feature vector.
    Type: Grant
    Filed: January 27, 2006
    Date of Patent: June 29, 2010
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Daniel Graupe, Menachem H. Graupe, Yunde Zhong
  • Separation of one or more fetal heart component signals from heart signal information obtained from a pregnant female
    Patent number: 7680531
    Abstract: One or more fetal heart component signals in one example are separated from heart signal information obtained from a pregnant female based on singular value decomposition.
