An alertness monitoring system includes: means to measure velocity and amplitude of eyelid and eye movement; and storage means to continuously record the measurements. A data processor calculates the blink amplitude to velocity ratio and / or the saccade amplitude to velocity ratio and compares the measurements against a predetermined scale. The scale is derived from averaged measurements of the eye and eyelid movement parameters for a sample population measured against predetermined incremental blood alcohol levels. The output of the system can include a display for showing the alertness measurement based on the scale, or an alarm means triggered by the scale reading reaching a predetermined limit based an the blood alcohol level scale.

The present invention in several embodiments is a cell phone with breath analyzer that can store a preprogrammed list of phone numbers that are not to be called once a person's blood alcohol level has reached a specific point. This device could look similar to traditional cell phones. Within the mouth piece, or other place on or in the phone is a blood alcohol detector. As a person talks / breaths into the phone, their blood alcohol level will be measured. If the level is over a predetermined amount, a previously programmed list of phone numbers cannot be accessed. This unit may also have the capability to store a help list for the user. This list would allow the consumer to easily call a specific list of individuals if they were in need of a ride or other forms of assistance.

A chemical vapor sensor is provided that passively measures a suspect chemical species of interest with high sensitivity and chemical specificity, for use with safety systems. A vapor concentrator amplifies a suspect chemical vapor concentration to a detectible level, for use with an infrared detector. Compensation is provided for environmental variations that may influence the passive measurement of the chemical vapor sensor. Environmental variations may include extrinsic vapors in the surrounding air, or air currents that divert the sample vapor as it drifts from the suspect vapor source to a sampling intake. In an example, ethanol vapor is measured and carbon dioxide tracer measurements are used to calculate an ethanol vapor measurement that is adjusted for environmental variations. In an aspect, a time artifact filter sets the output of the carbon dioxide sensor to match the time dependence of the ethanol sensor, to calculate blood alcohol concentration.

The process for detection and for quantitative determination of substances emitted or perspired through the skin is derived from flow diffusion analysis. The measuring system conceived for this purpose uses a diffusion half cell through which an acceptor medium flows and which is closed by a membrane. For the duration of the measurement, the membrane is brought into contact with the skin or a closed gas volume formed over the skin. With the process and the related measuring system, the blood alcohol level can be determined with a good degree of precision indirectly via the quantity of (gaseous) ethanol emitted through the skin.
