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.
Claims16
A vehicle safety rollover device, that upon detection of a vehicle rollover, automatically shuts-off power to an ignition system of said vehicle and notifies need to shut down an electrical system of said vehicle, said device comprising:
- (a) a power input;
- (b) a ground input (105) operatively connected to a vehicle common ground;
- (c) a first latching relay switch (103) and a second latching relay switch (117), each comprising:
- (i) an input,
- (ii) a first output position,
- (iii) a second output position,
- (iv) a set pin, and
- (v) a reset pin,
- wherein each latching relay switch is initially in the first output position, wherein each latching relay switch switches from the first output position to the second output position when power is supplied to the set pin, wherein each reset pin is connected to the ground input (105);
- (d) an ignition start input (111) operatively connected to the input of the first latching relay switch (103);
- (e) an ignition start output (115) operatively connected to the first output position of the first latching relay switch (103);
- (f) an electrical shut-off signal (112) operatively connected to the second output position of the second latching relay switch (117), wherein the input of the second latching relay switch (117) is operatively connected to the power input;
- and
- (g) a circular arc level (200), herein referred to as a CAL sensor (200), comprising an arcuate tube (201) having light emitters and detectors coupled to an exterior of the arcuate tube (201), the CAL sensor (200) configured to supply power to each set pin when the CAL sensor (200) is activated,
- wherein initially, power flows through the first latching relay switch (103) to an ignition relay of the ignition system, wherein the second latching relay switch (117) disconnects the electrical shutoff signal (112) from the power input,
- wherein when the CAL sensor (200) is activated, power flows from the power input to each set pin, causing the first (103) and the second (117) latching relay switches to switch from the first output position to the second output position, whereupon switching, power to the ignition relay is disconnected, wherein power then flows to the electrical shutoff signal (112) via the second latching relay switch (117), thereby causing the electrical system of the vehicle to shut down.
A vehicle safety rollover device, that upon detection of a vehicle rollover, automatically shuts-off power to an ignition system of said vehicle and notifies need to shut down an electrical system of said vehicle, said device comprising:
- (a) an ignition control relay (517) having a first latching relay switch (103) and a second latching relay switch (117);
- (b) a sensor (200) configured to supply power to the first latching relay switch (103) and the second latching relay switch (117) when the sensor (200) is activated;
- wherein when the sensor (200, 510) is activated, power flows from the power input to a set pin of each of the first latching relay switch and the second latching relay switch, causing the first latching relay switch (103) and the second (117) latching relay switches to switch from a first output position to a second output position, whereupon switching, power to the ignition relay is disconnected, wherein power then flows to an electrical shutoff signal (112) via the second latching relay switch (117), thereby causing the electrical system of the vehicle to shut down.
