Alcohol detection system
First Claim
1. A drunk driving detection system for incorporation into a vehicle, the system comprising:
- a first liquid-impermeable and air-permeable film provided to cover a first opening in an object which is to be grasped by a driver of the vehicle;
a pair of first contact detection electrodes provided on a surface of the first film;
a first alcohol sensor provided to detect a level of alcohol introduced into the first opening; and
a control circuit coupled to the first contact detection electrodes and the first alcohol sensor, the control circuit operable to measure a resistance between the first contact detection electrodes;
wherein when the resistance is within a predetermined range, the control circuit determines the driver is in contact with the first film and detects an alcohol drinking condition of the driver based on an output from the first alcohol sensor.

Abstract
A drunk driving detection system to be incorporated in a vehicle includes a steering wheel, a film, a pair of contact detection electrodes, an alcohol sensor, and a control circuit. The steering wheel is provided with an opening in a portion to be grasped by a driver. The film is liquid-impermeable and air-permeable, and covers the first opening. The contact detection electrodes are provided on the film. The alcohol sensor is provided in a space in communication with the opening. The control circuit is connected to the contact detection electrodes and the alcohol sensor, and measures the resistance between the contact detection electrodes. When the resistance is within a predetermined range, the control circuit determines that the driver is in contact with the film and detects an alcohol drinking condition of the driver based on the output from the alcohol sensor.

19. An alcohol detection system for detecting an alcohol consumption level of a human, the system comprising:
-
a liquid-impermeable and air-permeable film provided to cover an opening in an object which the human contacts; a pair of contact detection electrodes provided on a surface of the film; an alcohol sensor provided to detect a level of alcohol introduced into the opening; and a control circuit coupled to the contact detection electrodes and the alcohol sensor, the control circuit operable to measure a resistance between the contact detection electrodes; wherein when the resistance is within a predetermined range, the control circuit determines the human is in contact with the film and detects an alcohol consumption level of the human based on an output from the alcohol sensor. - View Dependent Claims (20)
