Abstract
A vehicle safety rollover device utilizing a circular arc level for detecting vehicle rollover is disclosed. Upon detection, the device automatically shuts-off power to an ignition system and notifies for shut-down of the electrical system of the vehicle. The circular arc level is capable of measuring gravitational norm deviation while remaining impervious to the effects of acceleration, deceleration, impact, and centripetal forces.
