Electronic module assembly for controlling aircraft restraint systems
First Claim
1. An electronic module assembly for controlling the deployment of one or more airbags in a vehicle, comprising:
- a power source;
a crash sensor configured to produce a signal in response to a crash event;
an accelerometer that is configured to produce a signal in response to a crash event;
a processor configured to receive the signals from the crash sensor and the accelerometer, wherein the processor is configured to;
start a timer upon detection of the signal from the crash sensor;
determine if a signal has been received from the accelerometer indicating the occurrence of the crash event;
if signals from both the crash sensor and the accelerometer indicate a crash event thenread a timing value selected for an inflator in a memory associated with the inflator;
determine if the timer has a value equal to the timing value selected for the inflator; and
produce a signal to fire the inflator when the timer has a value equal to the timing value selected for the inflator.

Abstract
An electronic module assembly for controlling the deployment of one or more airbags in an aircraft includes a power source, a crash sensor configured to produce a signal in response to a crash event and an accelerometer that is configured to produce a signal in response to a crash event. A processor starts a timer upon detection of the signal from the crash sensor. When the processor receives a signal from the crash sensor, the processor is configured to determine if a signal has also been received from the accelerometer and if signals from both the crash sensor and the accelerometer indicate a crash event then the processor reads a memory associated with an inflator. The processor reads a timing value selected for the inflator and fires the inflator when the timer has a value equal to the timing value selected for the inflator.
