Abstract: The monitoring breathalyzer has an alcohol sensor, a non-volatile memory, a processing unit or processor, a screen and a housing to house these components. The processing unit determines the accuracy of the breathalyzer using the user's body as a simulator. In monitoring mode, the processing unit receives a BAC% measurement from the alcohol sensor based on the breath sample provided by the user at a sample time to provide reference point. The sample time is determined based on the user's metabolism rate or based on a time to a predetermined calibration point from a drink start time.

Abstract: The calibrating breathalyzer comprises an alcohol sensor, a non-volatile memory, a processing unit or processor, a display and a housing to house these components. The processing unit can calibrate the breathalyzer using the user's body as a simulator based on the user's metabolism rate, type and amount of alcohol consumed by the user. The processing unit determines a sample time to receive a breath sample from the user based on a time to a predetermined calibration point from the drinking start time calculated using the user's metabolism rate and the determined maximum alcohol level. The BAC % measurement based on the user's breath sample at the sample time is used as a reference point in calibrating the breathalyzer.

Abstract: The present invention describes a replaceable breath alcohol sensor module that can be replaced with a new pre-calibrated breath alcohol sensor module or re-calibrated. The breath alcohol sensor module requiring calibration can be removed from the body of a Breath Alcohol Testing Device (commonly called “breathalyser” or “breathalyzer”). The breath alcohol sensor module can be separately calibrated for accurate calculation of “percent blood alcohol concentration” (% BAC) based on breath air samples and then re-installed into the breath alcohol tester or the old breath alcohol sensor module can be replaced with a new pre-calibrated breath alcohol sensor module. The present invention improves upon and/or replacing the current method of re-calibration at a breathalyzer service center.
