Abstract: A device that causes a weapon to fire upon a target when the weapon is enabled by an operator, and when the weapon point of impact passes through a target or in a proximity thereto and when the target satisfies certain criteria as determined by one or more sensors/designations. The invention triggers the release of a round, multi-round burst, rocket, missile, or other projectile(s) when enabled by the operator, and when the target passes through the point of impact (or desired/computed proximity thereto), relieving the operator of the split second judgment in timing the release and/or cessation of such fire. The results include reduction in off-target rounds fired, increased hit rate, conservation of ammunition, more effective targeting for non-motion-stabilized weapons , and the introduction of a backup mode for nominally motion-stabilized weapons which may allow effective operations when primary stabilization systems fail or are overwhelmed by dynamics.
