Methods and apparatus for mechanical reserve power sources for gun-fired munitions, mortars, and gravity dropped weapons
First Claim
1. A power source comprising:
- a power generation device;
a mass-spring unit having a mass and an elastic element operatively connected to the power generation device; and
one or more retention fingers releasably engaged with the mass-spring unit for retaining the mass-spring unit in a position such that potential energy is stored therein and for releasing the potential energy upon occurrence of an event to generate electrical energy in the power generation device, the one or more retention fingers having a first end fixed at a base and a second end releasably engaged with the mass-spring unit.

Abstract
A power source including: a power generation device; a mass-spring unit having a mass and an elastic element operatively connected to the power generation device; and one or more retention fingers releasably engaged with the mass-spring unit for retaining the mass-spring unit in a position such that potential energy is stored therein and for releasing the potential energy upon occurrence of an event to generate electrical energy in the power generation device, the one or more retention fingers having a first end fixed at a base and a second end releasably engaged with the mass-spring unit. The occurrence of the event can be one or more of an acceleration and spinning of the base. Also disclosed is a power source having one or more retention fingers that are slidable with respect to a base such that the engagement of the first end is released upon a spinning of the base.

30. A power source comprising:
-
a power generation means for converting potential energy into electrical energy; a mass-spring means for vibrating upon an occurrence of an event; and retention means releasably engaged with the mass-spring means for retaining the mass-spring unit in a position such that potential energy is stored therein and for releasing the potential energy upon the occurrence of the event to generate electrical energy in the power generation device, the retention means being rotatably engaged with respect to a base.
