METHOD FOR EVALUATING HUMAN FATIGUE Russian patent published in 2003 - IPC

FIELD: medicine. SUBSTANCE: method involves periodically measuring critical flicker fusion frequency change velocity. Dynamic critical flicker fusion frequency phase trajectory is plotted in critical flicker fusion frequency value - critical flicker fusion frequency change velocity coordinates The absolute value of the critical flicker fusion frequency at given time moment is mapped as coordinate value on X axis and critical flicker fusion frequency change velocity is mapped to Y axis. Change velocity being positive, the point is placed above the X axis. When negative, the point is placed under the X axis. The time of fatigue or overfatigue onset is determined from changes in phase trajectory direction. EFFECT: high accuracy of analysis. 2 dwg, 2 tbl
