  • Alpha-wave amplitude selector with window slicer
    Patent number: 5450854
    Abstract: An alpha-wave amplitude selector with a window slicer quickly selects and detects a time domain in which the amplitude of alpha component in brain waves exceeds or falls below a given threshold levels for use in biofeedback. A combination of a window slicer that receives alpha wave as input and an RS flip-flop connected to the window slicer significantly reduces a time-delay between a point at which the amplitude of alpha wave exceeds or falls below a preset level and a point at which a feedback stimulus is given.
