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

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