An activation device is configured to activate a protection apparatus for protecting an occupant. The activation device includes a front collision detection unit and a rear collision detection unit. The front collision detection unit outputs a front-collision-state activation signal to a front-collision protection apparatus so as to activate the front-collision protection apparatus when detecting front collision of the vehicle. The rear collision detection unit outputs a rear-collision-state activation signal to a rear-collision protection apparatus so as to activate the rear-collision protection apparatus when detecting rear collision of the vehicle. The rear collision detection unit prohibits output of the rear-collision-state activation signal to the rear-collision protection apparatus for a first period when the front collision detection unit detects front collision of the vehicle.

A computer (CPU) applied a faulty operation prevention circuit outputs a pulse signal having a predetermined period during normal operation. If the computer does not output the pulse signal during the predetermined period, a AND gate in the faulty operation prevention circuit shuts off a control signal output from the computer which can ignite a squib in a vehicular occupant protecting system because the computer is not working. The AND gate keeps shutting off the control signal until the computer outputs the pulse signal. Therefore, the faulty operation prevention circuit prevents the squib from being ignited based on a faulty operation of the computer.

A control system for adjusting an antenna rotatably mounted on a vehicle to directly receive a transmitting signal from a geostationary satellite so as to apply it to a receiving equipment on the vehicle. The control system comprises a first sensor for sensing a first difference between a standard direction and a travelling direction of the vehicle, a second sensor for sensing a second difference between the travelling direction of the vehicle and a direction of the antenna, a microcomputer programmed to determine a third difference between the travelling direction of the vehicle and a direction of the satellite in accordance with the first difference on a basis of a predetermined difference between the standard direction and the direction of the satellite and to determine an adjustment angle for rotation of the antenna in accordance with the second and third differences, and an actuator for effecting for rotation of the antenna with the adjustment angle.
