- Airbag — A passive safety device integrated into the structure of modern motor vehicles, consisting of a flexible inflatable nylon fabric cushion, microscopic impact sensors, and a pyrotechnic gas generator. Upon a violent collision, the system triggers an ultra-fast chemical reaction that inflates the air bag in just a few milliseconds, providing a structural cushioning barrier between the passengers' bodies and the rigid elements of the cabin, massively reducing the risk of severe trauma.
- Car alarm — An acoustic or optical electronic system installed on a motor vehicle with the purpose of preventing break-ins, theft, or unauthorized entry; a car security device that triggers automatically through motion, shock, or proximity sensors.
- Self-triggering — The act of self-triggering and its result; an automated or mechanical process through which a system, device, weapon, or software program activates autonomously, as a result of detecting an external stimulus or meeting an internal logical condition, without external manual intervention. This structural mechanism is vital for the operation of safety systems, sensors, and cameras.
