Patent No. 5595488

Apparatus and method for monitoring and improving the alertness of a subject (Gozlan, et al., Jan 21, 1997)

Abstract

Apparatus and method for monitoring and for improving the state of alertness of a subject while he continues to perform a primary task, driving a vehicle, operating machinery, etc. The apparatus includes stimulation apparatus for issuing stimuli to the subject and response apparatus for enabling the subject to reply to the stimuli. The stimuli can be audible, visual or tactile. Test results are processed and compared to baseline values taken when the subject is displaying a normal state of alertness. The rate of activation of the stimulation apparatus increases inversely with a deteriorating state of alertness of the subject to improve the state of alertness of the subject. The apparatus can be fashioned in a wide range of devices including a hand-held portable device, a wristwatch, a behind-the-ear (BTE) clip, a pair of spectacles, and for installation in a steering wheel.

Notes:

The present invention is for apparatus and method for monitoring and improving subject alertness which combines the beneficial features of discrimination level tests and cognitive tests. The apparatus and method can be readily adapted for application in a wide range of different environments including when operating a vehicle, within the confines of a laboratory, under field conditions, etc.

While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made.
