Electronic module assembly for controlling aircraft restraint systems

1. An electronic module assembly for controlling the deployment of one or more airbags in an aircraft, the electronic module assembly comprising:

one or more processors configured to receive signals from a crash sensor and an accelerometer, wherein the one or more processors are configured to:

receive, from the crash sensor, a first signal indicating an occurrence of a crash event;

receive, from the accelerometer, a second signal indicating the occurrence of the crash event; and

responsive to receiving the first signal and the second signal:

obtain a timing value for an inflator from a plurality of timing values; and

generate a third signal to fire the inflator based, at least in part, on the timing value.

2. The electronic module assembly of claim 1 , wherein the one or more processors are further configured to generate a fourth signal to fire another inflator.

3. The electronic module assembly of claim 2 , wherein generating the fourth signal is performed responsive to receiving the first signal and the second signal.

4. The electronic module assembly of claim 1 , wherein obtaining the timing value is based, at least in part, on a configuration of a seat in the aircraft.

5. The electronic module assembly of claim 1 , wherein the one or more processors are further configured to:

determine if a status of a seat belt buckle needs to be determined before firing the inflator and if so,

determine the status of the seat belt buckle before generating the third signal to fire the inflator.

6. The electronic module assembly of claim 5 , further comprising a seat belt latch detection circuit including at least a circuit to direct power from a power source to a Hall effect sensor.

7. The electronic module assembly of claim 6 , wherein the seat bel latch detection circuit further includes at least a comparator for comparing a signal from the Hall effect sensor against a pre-determined voltage.

8. The electronic module assembly of claim 1 , further comprising a relay that is set to provide power to an inflator by a signal from the crash sensor.

9. The electronic module assembly of claim 8 , further comprising a transistor in series with the inflator to complete a current path from the relay and though the inflator in order to fire the inflator.

10. The electronic module assembly of claim 1 , wherein the crash sensor comprises one or more reed switches.

11. A computer-implemented method for controlling the deployment of one or more airbags in an aircraft, comprising:

receiving, from a crash sensor, a first signal indicating an occurrence of a crash event;

receiving, from an accelerometer, a second signal indicating the occurrence of the crash event; and

responsive to receiving the first signal and the second signal:

obtaining a timing value for an inflator from a plurality of timing values; and

generating a third signal to fire the inflator based, at least in part, on the timing value.

12. The method of claim 11 , further comprising generating a fourth signal to fire another inflator.

13. The method of claim 12 , wherein generating the fourth signal is performed responsive to receiving the first signal and second signal.

14. The method of claim 11 , further comprising starting a timer upon receiving the first signal from the crash sensor.

15. The method of claim 14 , wherein generating the third signal based, at least in part, on the timing value comprises comparing a value of the timer with the timing value.

16. A computer-readable storage medium storing contents that, when executed by one or more processors, cause the one or more processors to:

receive, from a crash sensor, a first signal indicating an occurrence of a crash event;

receive, from an accelerometer, a second signal indicating the occurrence of the crash event; and

responsive to receiving the first signal and the second signal:

obtain a timing value for an inflator from a plurality of timing values; and

generate a third signal to fire the inflator based, at least in part, on the timing value.

17. The computer-readable storage medium of claim 16 , wherein the contents further cause the one or more processors to generate a fourth signal to fire another inflator.

18. The computer-readable storage medium of claim 17 , wherein generating the fourth signal is performed responsive to receiving the first signal and the second signal.

19. The computer-readable storage medium of claim 16 , wherein obtaining the timing value is based, at least in part, on a configuration of a seat.

20. The computer-readable storage medium of claim 16 , wherein the contents further cause the one or more processors to:

determine if a status of a seat belt buckle needs to be determined before firing the inflator and if so,

determine the status of the seat belt buckle before generating the third signal to fire the inflator.
