摘要： 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.

摘要： A highly accurate gas sensor includes a circuit having an improved S/N ratio. First ends of a heat generating element and reference resistor brought into contact with a detected gas are commonly connected, and second ends are respectively connected to a first switch. The first switch is connected with a power source apparatus for supplying a current to the heat generating element or reference resistor. A voltage measuring portion measures a voltage across the heat generating element or reference resistor. An operating portion switches the first switch between the reference resistor and heat generating element by a predetermined timing by determining a condition of controlling a power source apparatus for supplying at least 3 stages of step-like currents to the heat generating element from the voltage across the reference resistor. A voltage measuring portion measures the voltage across the heat generating element and calculates a concentration of a detected gas.

摘要： In a gas sensor, at least three levels of current are supplied to a heating element successively in a step-like manner for a predetermined time period. An arithmetic unit receives both-end voltages of the heating element for the respective current after elapse of the predetermined time period and calculates temperature from the both-end voltage of the heating element obtained when the lowest current flows. Then, the arithmetic unit corrects the both-end voltages of the heating element using the calculated temperature, a zero-point correction equation and a sensitivity correction equation to obtain respective standardized output values. Subsequently, the arithmetic unit calculates humidity based on the difference between the standardized output values, and corrects the standardized outputs based on the calculated humidity and humidity correction equations. By this method, the arithmetic unit calculates concentration of detection target gas.
