Abstract: In an electrochemical gas sensor (10), a first sensing element (21) is stored in a first storage portion (31). A moisture permeable film (24) is disposed in a first introduction inlet (31A) of the first storage portion (31). The moisture permeable film (24) substantially prevents a to-be-detected gas from permeating therethrough. A second sensing element (22) is disposed in a space into which water vapor and the to-be-detected gas contained in a target gas flow. In such a configuration, the electrochemical gas sensor (10) is capable of detecting a to-be-detected gas having a concentration of 0 or more and 1 ppm or less.

Abstract: An arrangement is realized in which the motion sickness level of an occupant of a vehicle while automatic driving is being carried out is estimated, and in case the sickness level becomes equal to or larger than an existing standard value, a warning is output to prompt the occupant to change to manual driving, making it possible to return to safe manual driving. The detected information from an acceleration sensor is input and the sickness level of an occupant of a vehicle while automatic driving is being carried out is estimated. Furthermore, in case an estimated value and a warning output standard value are compared with each other and the estimated value becomes equal to or larger than the standard value, the outputting of a warning for prompting the occupant to switch from automatic driving to manual driving is executed. Moreover, a learning process based on operation information of an operator after the warning has been output is carried out.
