A vehicular passenger protecting apparatus preferably used in an air bag to be spread at a side portion in a vehicular compartment of an automobile. The substrate comprises a catalyst composition comprising a support, a catalyst, and a sufficient amount of SMSI material such that, upon exposure to a gas stream, less than or equal to about 35 wt % of hydrocarbons in the gas stream are burned. During inhalation, the first valve opens to allow air flow into the first branch, and closes during exhalation to force air through the nozzle, thereby inducing a vacuum for drawing air from the damaged region. Electronic hardware can be field reconfigured to accommodate different display formats andor application functions. A determining device is configured to determine whether a magnitude of the acceleration detected by the acceleration detector exceeds a predetermined threshold value.
