Abstract

A method for stepping a first member relative to a second member associated with a projectile. The method including: providing one of the first and second members with one of a plurality of pockets and more than three movable pins offset from each other with a first spacing; providing the other of the first and second members with the other of the plurality of pockets and more than three movable pins offset from each other with a second spacing, where the first spacing is different from the second spacing; and engaging at least one of the movable pins into a corresponding pocket to step one of the first and second members a predetermined linear and/or rotary displacement. Where the engaging includes selectively varying a step size between the first and second member.

First claim

What is claimed is:

1. A method for stepping a first member relative to a second member associated with a projectile, the method comprising:
providing one of the first and second members with one of a plurality of pockets and movable pins offset from each other with a first spacing;
providing the other of the first and second members with the other of the plurality of pockets and movable pins offset from each other with a second spacing, where the first spacing is different from the second spacing; and
engaging at least one of the movable pins into a corresponding pocket to step one of the first and second members a predetermined linear and/or rotary displacement;
wherein the engaging comprises sequentially engaging two of the plurality of movable pins in their corresponding pockets, such that the relative movement between the first and second members is moved two steps from a reference position.

2. A method for stepping a first member relative to a second member associated with a projectile, the method comprising:
providing one of the first and second members with one of a plurality of pockets and more than three movable pins offset from each other with a first spacing;
providing the other of the first and second members with the other of the plurality of pockets and more than three movable pins offset from each other with a second spacing, where the first spacing is different from the second spacing; and
engaging at least one of the movable pins into a corresponding pocket to step one of the first and second members a predetermined linear and/or rotary displacement;
wherein the engaging comprises selectively varying a step size between the first and second members.
