Abstract
The safing system employs a multi-axis accelerometer system and multi-axis gyroscope system and a processor that is programmed to iteratively read acceleration data from the accelerometer system and apply a multi-axis rotation on the acceleration data using gyroscope data iteratively read from the gyroscope system to generate rotationally corrected acceleration data and further programmed to calculate a cumulative distance measure using the rotationally corrected acceleration data. The processor then compares the cumulative distance measure with a predetermined reference measure and to issue a control signal to enable arming of the device when the cumulative distance measure exceeds the reference measure.

A safing system to control arming of a device comprising:
- a multi-axis accelerometer system;
- a multi-axis gyroscope system;
- a processor programmed to iteratively read acceleration data from the accelerometer system and apply a multi-axis rotation to the acceleration data using gyroscope data iteratively read from the gyroscope system to generate rotationally corrected acceleration data and further programmed to calculate a cumulative distance measure using the rotationally corrected acceleration data;
- the processor being further programmed to compare the cumulative distance measure with a predetermined reference measure and to issue a control signal to enable arming of the device when the cumulative distance measure exceeds the reference measure.
A method of controlling arming of a device, comprising the steps of:
- using a processor to iteratively read acceleration data from a multi-axis accelerometer system and to apply a multi-axis rotation to the acceleration data using data iteratively read from a multi-axis gyroscope system to generate rotationally corrected acceleration data;
- using a processor to calculate a cumulative distance measure using the rotationally corrected acceleration data;
- using a processor to compare the cumulative distance measure with a predetermined reference measure and to issue a control signal to enable arming of the device when the cumulative distance measure exceeds a reference measure.
