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.

Claim (Index 15):
A circular arc level sensor ( 200 ), herein referred to as a CAL sensor ( 200 ), for detecting an inclination of a body, the CAL sensor ( 200 ) comprising:\n a) an arcuate tube ( 201 ), wherein a liquid partially fills the arcuate tube ( 201 ), wherein an air bubble ( 203 ) is disposed in the arcuate tube ( 201 ) such that the liquid and the air bubble ( 203 ) fill the arcuate tube ( 201 ), wherein the CAL sensor ( 200 ) is fixed to the body of the vehicle, wherein the CAL sensor ( 200 ) is in an upright position relative to gravity when an inclination of the CAL sensor ( 200 ) is zero, wherein when the CAL sensor ( 200 ) is in the upright position, the air bubble ( 203 ) is in a resting position at an apex of the arcuate tube ( 201 ); (b) a first light emitting element ( 205 ) disposed on an exterior of the arcuate tube ( 201 ) at a first location about 75\u00b0-90\u00b0 from the apex of the arcuate tube ( 201 ), wherein the first light emitting element ( 205 ) emits a first optical signal; (c) a second light emitting element ( 207 ) disposed on the exterior of the arcuate tube ( 201 ) at a second location about 270\u00b0-285\u00b0 from the apex of the arcuate tube ( 201 ), wherein the second light emitting element ( 207 ) emits a second optical signal; (d) a first photodetector ( 209 ) disposed on the exterior of the arcuate tube ( 201 ) at a third location about 75\u00b0-90\u00b0 from the apex of the arcuate tube ( 201 ), wherein the third location is opposite the first location such that the arcuate tube ( 201 ) is disposed between the first photodetector ( 209 ) and the first light emitting element ( 205 ), wherein the first photodetector ( 209 ) is positioned to detect the first optical signal; and (e) a second photodetector ( 211 ) disposed on the exterior of the arcuate tube ( 201 ) at a fourth location about 270\u00b0-285\u00b0 from the apex of the arcuate tube ( 201 ), wherein the fourth location is opposite the second location such that the arcuate tube ( 201 ) is disposed between the second photodetector ( 211 ) and the second light emitting element ( 207 ), wherein the second photodetector ( 211 ) is positioned to detect the second optical signal; and wherein when the CAL sensor ( 200 ) is in the upright position, the liquid blocks detection of the first optical signal and the second optical signal, wherein when the CAL sensor ( 200 ) is tilted within a first threshold window, centered at about 75\u00b0-5\u00b0 from the apex of the arcuate tube ( 201 ), the air bubble ( 203 ) travels to rest between the first and third location permitting the first optical signal to travel through the air bubble ( 203 ) to the first photodetector ( 209 ) for detection, thus sensing the inclination, wherein when the CAL sensor ( 200 ) is tilted within a second threshold window, centered about 270\u00b0-285\u00b0 from the apex of the arcuate tube ( 201 ), the air bubble ( 203 ) travels to rest between the second and fourth location permitting the second optical signal to travel through the air bubble ( 203 ) to the second photodetector ( 211 ) for detection, thus sensing the inclination.
