Laboratory Testing of Two Prototype In-Vehicle Breath Test Devices

摘要

The report presents the results of laboratory testing of two recently developed prototype in-vehicle breath test devices. These devices are designed to prevent persons with alcohol on their breath from driving a car. The devices tested were the SOBERLYZER and the ALCOHOL BREATH IGNITION CONTROLLER (A. B. I. C.). In addition to alcohol sensors, these devices have features built into them to check whether the sample being introduced is a true breath sample. The SOBERLYZER has a temperature sensor designed to check whether the sample being introduced is the same temperature as a human breath. The A. B. I. C. has a pressure switch designed to check whether the force activating the system is as strong as a human breath. Only one prototype unit of each device was tested in this research project. Nevertheless, the findings should be useful to those who are attempting to develop practical in-vehicle breath test devices.
