Shock protection for electro-mechanical devices of host devices employing inertial navigation systems

摘要

A shock protected electronic device comprising a position receiver, an electromechanical device, a position process, and a protect process. The position receiver generates at least one position signal. The motion sensor generates at least one motion signal. The electromechanical device operates in a normal mode and a protect mode. The position process generates position data indicative of a position of the shock protected electronic device based on at least one of the position signal and the at least one motion signal. The protect process generates a protect signal based on the at least one motion signal. The electromechanical device enters the protect mode when the protect process generates the protect signal.

1. A shock protected electronic device comprising:
a position receiver that generates at least one position signal of the device; a motion sensor that generates at least one motion signal; an electromechanical device, where the electromechanical device operates in a normal mode and a protect mode; a position data generator that receives the at least one motion signal from the motion sensor and generates position data indicative of a position of the shock protected electronic device based on the position signal and the at least one motion signal; and a protect signal generator that generates a protect signal based on the at least one motion signal and transmits the protect signal to the electromechanical device, which enters the protect mode in response to receiving the protect signal from the protect signal generator.
