Abstract: A method of measuring a chemical vapor concentration is provided. A chemical vapor sensor measures a chemical species of interest with high sensitivity and chemical specificity. In an aspect, an ethanol vapor sensor is provided, sized for being inconspicuous and on-board a vehicle, having a passive measurement mode and an active breathalyzer mode, for detecting a motor vehicle driver that exceeds a legal limit of blood alcohol concentration (BAC), for use with vehicle safety systems. For the passive mode, a vapor concentrator is utilized to amplify a sampled vapor concentration to a detectable level for use with an infrared (IR) detector. In an aspect, ethanol vapor in a vehicle cabin is passively measured and if a predetermined ethanol level is measured, a countermeasure is invoked to improve safety. In an aspect, an active breathalyzer is used as a countermeasure. The active breathalyzer can be imposed for a number of vehicle trips or for a predetermined time period.

Abstract: A method to avert an unlawfully intoxicated driver from operating a vehicle is provided. The method utilizes a passive ethanol vapor sensor to measure ethanol vapor concentration in air from a vehicle cabin and imposes a safety response when the passive ethanol vapor sensor detects that a sample of vehicle cabin air indicates that a vehicle occupant exceeds the legal blood alcohol concentration (BAC) for a motor vehicle driver. The ethanol vapor sensor may have a passive measurement mode and an active breathalyzer mode. Ethanol vapor in a vehicle cabin may be passively measured and if a predetermined ethanol level is measured, a countermeasure is invoked to improve safety. An active breathalyzer may be used as a countermeasure. The active breathalyzer can be imposed for a number of vehicle trips or for a predetermined time period.
