Abstract
A method and a system of deploying an ignition interlock device (IID). The method comprises receiving a time series of breath alcohol content (BrAC) measurements that are unitarily sourced from a pre-identified user, each BrAC measurement of the time series including an alveolar breath component and an interferent breath component; estimating a dissipation rate of alcohol attributable to the pre-identified user in accordance with the time series of BrAC measurements; determining, responsive to estimating the dissipation rate of alcohol, at least a subset of the BrAC measurements as being based on the alveolar breath component but not the interferent breath component; and performing one of triggering and not triggering the IID into a lockout state based on the at least a subset of the BrAC measurements.
