Abstract
A system and method for monitoring the alertness of a subject are provided. A Doppler sensor is disposed to sense a parameter pertaining to the subject, the sensor being one of an acoustic sensor and a microwave sensor. Signals from the sensor are processed through an alertness monitoring algorithm for generating processed signals. It is thereafter determined whether an impairment of alertness event pertaining to the subject has occurred based on the processed signals. Feedback is then provided to the subject based on a determination of whether an impairment of alertness event pertaining to the subject has occurred.
