Abstract: A mechanism including: a toggle rotatably connected to a base structure; a stop fixed to the base for limiting a rotational travel of the toggle, the stop being fixed to the base such that there is no relative movement between the stop and the base; a biasing element having a first end attached to the base and a second end attached to the toggle to bias the toggle towards the stop when the toggle is positioned on a first side of a singular position and the toggle is biased towards an opposite direction from the stop when the toggle is positioned on a second side of the singular position; and an inertial element movably disposed relative to the base and the toggle to move the toggle from the first side to the second side of the singular position when the base undergoes an acceleration event greater than a predetermined threshold.

Abstract: A device including: a body having one or more walls defining an internal cavity, the wall(s) having one or more grooves extending in a longitudinal direction of the internal cavity and extending at least partially along a periphery of the wall(s); a mass movable in the longitudinal direction within the internal cavity, the mass having one or more holes extending in a direction offset from the longitudinal direction; a ball partially disposed in the groove(s) and partially disposed in each hole(s); and an elastic material for biasing the ball towards the groove(s). The groove(s) having a shape such that the acceleration greater than a predetermined acceleration profile causes the ball to first move opposite to the direction of the acceleration and then bounce to move in the direction of the acceleration until the ball(s) moves into the hole(s) to free the mass to move longitudinally opposite to the acceleration.

Abstract: A munition including: a control surface actuation device including: an actuator having two or more pistons, each of the pistons being movable between an extended and retracted position, the retracted position resulting from an activation of each of the two or more pistons; and a movable rack having a pocket corresponding to each of the two or more pistons, each pocket being engageable with a corresponding portion of each of the two or more pistons, a distance between the pockets being different than a distance between the portions of the two or more pistons, such that activation of the portion into the corresponding pocket sequentially translates the rack; and a control surface operatively connected to the rack such that translation of the rack rotates the control surface.

Abstract: A brake for use with a shock testing machine, the brake including: a brake material for generating a frictional force to stop a test platform when the brake material is urged against an opposed braking surface; links for rotatably connecting the brake material to the test platform; a biasing spring to bias the brake material towards the braking surface; a restraint mechanism for restraining the braking material, against a biasing force of the biasing spring, in a retracted position where the braking material is separated from the braking surface; and a release mechanism for releasing the restraint of the release mechanism to bias the brake material against the braking surface; wherein the links are configured such that relative movement between the brake material and braking surface while the brake material and braking surface are engaged causes a frictional force between the brake material and braking material to increase.

Abstract: An actuating mechanism including: a base having a helically shaped passage; a movable mass having a helically shaped projection, a first surface of the helically shaped projection mating with a corresponding second surface of the helically shaped passage; and a spring biasing the first surface against the second surface when the base is not being accelerated. Wherein the helically shaped passage, the helically shaped projection and the spring are configured to maintain the helically shaped projection in a first portion of the helically shaped passage upon the base experiencing a first acceleration profile having a first magnitude and a first duration and allow the mass to move to a second portion of the helically shaped passage upon the base experiencing a second acceleration profile having a second acceleration lower than the first acceleration and a second duration greater than the first duration.

Abstract: A method for rotating a toggle link upon an acceleration event greater than a predetermined threshold. The method including: biasing a toggle link against a stop when the acceleration event is less than the predetermined threshold, a position of the toggle link against the stop being on a first side of a singular position of the toggle link; biasing the toggle link towards an opposite direction from the stop when the toggle link is positioned on a second side of the singular position; and moving the toggle link from the first side of the singular position to the second side of the singular position when the base structure undergoes an acceleration event greater than a predetermined threshold.
