The present invention monitors a physiological process intrinsic to humans and which measures directly the approach of a sleep state. When sleep onset is detected, the subject is restored to a fully awake state by an alert mechanism. Sleep onset is determined by monitoring EEG and EMG signals of the subject with a bispectral index monitor and applying an analysis algorithm to the index values output by the monitor. As a person tires, the value of their bispectral index begins to drop and then oscillate back and forth between two discrete levels. This pattern is consistent among various subjects and indicates an early warning of impending sleep, before a dangerous loss of vigilance has occurred.

Alarm upon detection of impending sleep state

The present invention relates generally to the use of a combination of alkali metal hydroxides and alkaline-earth metal hydroxides as a scavenging material for cyanide gas. In particular, the present invention relates to a method and means for either filtering out cyanide gas or detoxifying areas contaminated with cyanide using Sodalime or Baralyme&trade;. The scavenging material of the invention is typically incorporated into a scrubbing device wherein a motor ( ) powers a fan ( ) to draw contaminated air into an inlet ( ) and across a filter ( ) which contains the scavenger material, thereby absorbing cyanide gas contained in the air.
