Devices and methods for maintaining an alert state of consciousness through brain wave monitoring

摘要

Disclosed are devices for monitoring and maintaining an alert state of consciousness in a subject wearing the device An alert mental state is maintained through monitoring of brain wave patterns to detect if a transition from an alert to a non-alert mental state is about to occur, or has occurred. If so, a stimulus, e.g., an audible tone, is provided until such time as an alert mental state, as assessed by brain wave activity, is restored. Also disclosed are methods for maintaining an alert mental state, as well applications for such devices and methods.
