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.
Claims30
A calibrating breathalyzer, comprising:
- an alcohol sensor for receiving a breath air sample and measuring percent blood alcohol concentration (BAC %) based on analysis of the breath sample;
- a non-volatile memory for storing calibration data of the alcohol sensor comprising one or more reference points;
- a processing unit for operating the breathalyzer in two modes:
- (A) a calibration mode to calibrate the breathalyzer using the user's body as a simulator by receiving information regarding a metabolism rate of the user, type and amount of alcohol consumed by the user, and a drinking start time;
- determining maximum alcohol level from the type and amount of the alcohol consumed by the user;
- determining 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 metabolism rate of the user and the maximum alcohol level;
- receiving a BAC % measurement from the alcohol sensor based on the breath sample provided by the user at the sample time to provide a reference point;
- and storing the reference point;
- and (B) an operation mode to provide a BAC % reading based on the BAC % measurement by the alcohol sensor and the calibration data stored in the non-volatile memory;
- a display for displaying the BAC % reading and other information to a user;
- and
- a housing to house the processing unit, the alcohol sensor, the non-volatile memory and the display.
Apparatus for calibrating a breathalyzer using a user's body as a simulator, comprising:
- an input device for receiving information regarding a metabolism rate of the user, type and amount of alcohol consumed by the user, and a drinking start time;
- a processor for:
- determining a maximum alcohol level from the type and amount of the alcohol consumed by the user, determining a sample time to receive a breath sample by the breathalyzer from the user based on a time to a predetermined calibration point from the drinking start time calculated using the metabolism rate of the user and the maximum alcohol level;
- and
- receiving a percent blood alcohol concentration (BAC %) measurement taken by the breathalyzer based on the breath sample provided by the user at the sample time to provide a reference point;
- a memory for storing the reference point;
- and
- a display for displaying the reference point to be inputted by the user as a calibration data into the breathalyzer.
A non-transitory computer readable storage medium comprising computer executable code for calibrating of a breathalyzer using a user's body as a simulator, the code comprising instructions for:
- receiving information regarding a metabolism rate of the user, type and amount of alcohol consumed by the user, and a drinking start time by a processor based device;
- determining a maximum alcohol level from the type and amount of the alcohol consumed by the user by the processor based device;
- determining a sample time to receive a breath sample by the breathalyzer from the user based on a time to a predetermined calibration point from the drinking start time calculated by the processor based device using the metabolism rate of the user and the maximum alcohol level;
- receiving by the processor based device a percent blood alcohol concentration (BAC %) measurement taken by the breathalyzer based on the breath sample provided by the user at the sample time to provide a reference point;
- storing the reference point in a memory of the processor based device;
- and
- displaying the reference point to be inputted by the user as a calibration data into the breathalyzer.
