Mechanical energy harvesting devices with safety and event detection for munitions and the like

Abstract

A method for storing energy in a device upon acceleration of the device. The method including: permitting a first movable member configured to be movable in one direction relative to a base; biasing the first movable member in a second direction opposed to the first direction; permitting a plurality of second movable members, to be each movable towards an engagement surface of the first movable member when subjected to a predetermined acceleration event in a direction offset from the first direction; and sequentially engaging a portion of the engagement surface, which when pressed causes a movement of the first movable member in the one direction against a biasing force of the first biasing member, upon an increasing acceleration of the base such that energy is stored in the first biasing member.
