Detection of pilot state during high-G by wavelet analysis of EEG signal

Abstract

Large acceleration forces can seriously affect the physiological conditions of the pilot and cause the loss of consciousness (G-LOC). There is a lack of quantitative method to detect the states of pilot during the high G condition so that more sophisticated protective device can be designed. We proposed a G-LOC detection and state determination method by use of wavelet analysis of EEG signal together with the application of the 1/f power theory.
