  • Epileptic seizure prediction by non-linear methods
    Patent number: 5857978
    Abstract: Methods and apparatus for automatically predicting epileptic seizures monitor and analyze brain wave (EEG or MEG) signals. Steps include: acquiring the brain wave data from the patient; digitizing the data; obtaining nonlinear measures of the data via chaotic time series analysis tools; obtaining time serial trends in the nonlinear measures; comparison of the trend to known seizure predictors; and providing notification that a seizure is forthcoming.
    Type: Grant
    Filed: March 20, 1996
    Date of Patent: January 12, 1999
    Assignee: Lockheed Martin Energy Systems, Inc.
    Inventors: Lee M. Hively, Ned E. Clapp, C. Stuart Daw, William F. Lawkins
  • Apparatus and method for epileptic seizure detection using non-linear techniques
    Patent number: 5743860
    Abstract: Methods and apparatus for automatically detecting epileptic seizures by monitoring and analyzing brain wave (EEG or MEG) signals. Steps include: acquiring the brain wave data from the patient; digitizing the data; obtaining nonlinear measures of the data via chaotic time series analysis; obtaining time serial trends in the nonlinear measures; determining that one or more trends in the nonlinear measures indicate a seizure, and providing notification of seizure occurrence.
