Abstract
A Self-Regulating Alcohol Breathalyzer has a Main Module Enclosure to channel breath evenly to three Fuel-Cell Sensors. Within the Main Module Enclosure are the Main Circuit Board and the Exhaust Fan. When a user blows into the straw, their breath will flow through the Main Air-Flow Channel, Solenoid Pumps are triggered and breath samples are pulled into the Fuel-Cells as the user's air pressure begins to decline. Each Fuel-Cell Sensor has an opening that protrudes into the Main Air Flow Channel and will have access to pull in samples of the breath passing through the channel. After the breath sample is acquired, the three Fuel Cells comparatively test for alcohol content.
Claims14
A self-regulating, multi-fuel-cell breathalyzer that can identify loss in calibration of a fuel-cell sensor, automatically recalibrate the sensor, and automatically disable the sensor that cannot be recalibrated, comprising:
- a) a main module with a main air-flow channel, a main circuit board having first multiple card-edge connectors and an air-pressure sensor in flow communication with the main air-flow channel;
- and
- b) multiple fuel-cell cartridges each having a fuel-cell sensor, a pump, a fuel-cell sensor intake in flow communication with the main air-flow channel and a second multiple card-edge connector connectable to one of the main module first multiple card-edge connectors.
