Abstract
A system for use in a motor vehicle, made up of a group of sensors such as accelerometers, a microprocessor, and a group of passenger-safety devices. The sensors' inform the microprocessor of the levels of acceleration at different points in the vehicle. The microprocessor processes this information, checks the sensors' functioning, the power source and the safety devices. In the case of a strong shock, the microprocessor triggers the safety devices suited to the particular situation: electromagnetic door-openers, safety belts with pyrotechnic tightening action, inflatable air bags, and loosening devices for safety belts.
