摘要： A vehicle passenger detecting device includes a judging circuit (6), which judges whether a passenger seated on a seat (1) is a child or not based on a load acting on each of areas of a seat portion (1a) of the seat for a vehicle, and the judging circuit (6), with a fastened sate of a seat belt (5a), judges whether or not a total load acting on the entire area of the seat portion is within a predetermined range, and when the total load is within the predetermined range, if a front outer load acting on a front outer area is a first threshold or more and the ratio of the front outer load to a front inner load acting on a front inner area is a second threshold or more, or the ratio of both outer loads acting on both of outer areas to both inner loads acting on both of inner areas is a third threshold or more, the judging circuit judges (6) that a seated passenger is a child.

摘要： A substance adsorption detection method and a sensor utilizing amounts of change in the optical characteristic of a sensitive thin film with respect to the adsorbed amount of a substance to be detected. A clad 4, a core 5, and a thin film 7 for detecting an adsorbed substance are sequentially stacked on a crystal oscillator 10 to constitute an optical waveguide layer 12 and a gas adsorption member 11. An incoming light prism 8 and an outgoing light prism 9 are provided on the surface of the core 5. Changes in the adsorbed mass of the target substance and in the optical characteristic involved can be detected accurately and simultaneously by utilizing a change in outgoing light originating from a change in propagation loss and a change in the oscillation characteristic of the oscillator 10, both caused by adsorption of the target substance on the core surface.

摘要： A passenger detecting device includes a plurality of weight sensors, a passenger judging and data updating means and an update forbidding means. The weight sensors are arranged at different positions of a seat for respectively detecting weights acting on the seat of a motor vehicle. The passenger judging and data updating means is capable of judging a passenger on the seat based on the loads detected by the weight sensors and updating information on the passenger. The update forbidding means prevents the passenger judging and data updating means from judging the passenger or prevents the information to be updated when a sum-weight fluctuation amount is not less than a first predetermined threshold value, where the sum-weight fluctuation amount is obtained by summing up weight function amounts which are absolute values of fluctuations of the loads detected by the weight sensors.
