Electrochemical sensors commonly used in breathalyzer devices detect the alcohol concentration in a fluid sample. The fluid sample is introduced into the electrochemical sensor, and a current is generated by the oxidation of alcohol within the fluid. The electrical output from the electrochemical sensor, plotted over time, forms an output curve, which can be used to estimate the alcohol concentration in the fluid sample. The technology disclosed herein includes various procedures for determining the amount of an electrochemically convertible substance in a fluid sample using a breathalyzer device, including detecting the water saturation level of the fluid sample. The disclosed technology involves measuring the electrochemical sensor outputs to quantify the alcohol content of the fluid sample.

The improved breath alcohol ignition interlock is for use with a vehicle having a proximity pilot circuit and is of the type adapted to: receive a signal when a vehicle has been enabled for activation of the drivetrain; upon receipt of that signal, trigger a breath tester to prompt for and receive a breath sample; upon receipt of a breath sample, test for alcohol; and upon a determination that the amount of alcohol in the sample is below the legal limit or other threshold, activate a relay. The improvement comprises: a normally open relay coupled to an ignition active circuit of the vehicle for activation thereby; a normally closed relay coupled to the ignition interlock for activation thereby; and a resistor, coupled to the relays in series, between the proximity pilot circuit and ground.

Methods and system for inhibiting a driver from cheating a vehicle breath alcohol sensor. The breath alcohol sensor is mounted within a vehicle and determines an alcohol concentration of a breath of an occupant. An image sensor generates images of the occupant within the vehicle. A processor is configured to determine whether the occupant is attempting to cheat the breath alcohol sensor by executing image processing on the images to identify a face of the occupant, objects in front of the face of the occupant, and / or whether the occupant is actually the one blowing into the breath alcohol sensor. If the image processing yields results that the driver is attempting to cheat the sensor, the processor can inhibit driver operation of the vehicle.
