Sobriety testing apparatus having OBD-II connection capability
First Claim
1. A sobriety interlock for a machine comprising:
- an alcohol detection device;
a computing device electrically connected to the alcohol detection device, the computing device capable of determining a blood alcohol concentration of an operator based on a signal received from the alcohol detection device, and capable of controlling the operation of the machine based on the blood alcohol concentration; and
an electronic circuit capable of connecting the computing device to an on-board diagnostic port on the machine.

Abstract
A sobriety interlock system having an alcohol detection device electrically connected to a computing device is provided. An electronic circuit is electrically connected between the computing device and an OBD-II port on a machine for receiving data related to operation of the machine. A breath sample is provided by an operator of the machine and the alcohol detection device determines the alcohol concentration of the breath sample. The computing device determines a blood alcohol concentration for the operator based on the breath alcohol concentration, and the computing device prevents or allows operation of the machine based on the level of the blood alcohol concentration. A memory device stores machine operation data received through the OBD-II port.
