Abstract
The monitoring breathalyzer has an alcohol sensor, a processing unit or processor, and a screen. 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 and determines a reference point from the BAC measurement. The sample time is determined based on a time to a predetermined calibration point from a drink start time.

1-20. (canceled)
A breathalyzer, comprising:
- an alcohol sensor to receive a breath air sample and comprising a sensor circuitry to detecting changes in conductivity based on an alcohol concentration in the breath sample to measure a blood alcohol concentration (BAC);
- a processing unit to determine an accuracy of the alcohol sensor using a user's body as a simulator in a monitoring mode by receiving a BAC measurement from the alcohol sensor based on the breath sample provided by the user at a sample time, the sample time determined based on a time to a predetermined calibration point from a drink start time;
- to determine a reference point from the BAC measurement;
- and to determine a BAC reading based on the BAC measurement by the alcohol sensor and pre-stored calibration data in an operation mode;
- and
- a screen to display the BAC reading and other information to the user.
