Feedback-controlled re-targeting apparatus for automatic firearm

A method, comprising:

• capturing, by sensors mounted on an apparatus body attached to a barrel of a firearm, a measurement of an initial line-of-sight to a target prior to a firing sequence of the firearm;
• receiving, by a feedback control unit of the apparatus, the measurement of the initial line-of-sight prior to the firing sequence;
• measuring, by the sensors, deviation from the initial line-of-sight after said capturing the measurement of the initial line-of-sight and during the firing sequence;
• receiving, by a chamber disposed in the body, combustion gases from the barrel during the firing sequence;
• receiving, by the feedback control unit, the deviation from the sensors;
• controlling, by the feedback control unit, ports in communication with the chamber to vary discharge of the combustion gases from the chamber during the firing sequence to generate forces on the barrel to drive the deviation to a minimum.

A method, comprising:

• for each target of multiple targets, capturing, by sensors mounted on an apparatus body attached to a barrel of a firearm, a measurement of a respective initial line-of-sight to the target prior to a firing sequence of the firearm;
• for each target of the multiple targets, receiving, by a feedback control unit of the apparatus, from the sensors the measurement of the respective initial line-of-sight to the target prior to the firing sequence;
• for each target of the multiple targets in a sequential fashion, measuring, by the sensors, deviation from the respective initial line-of-sight to the target during a respective portion of the firing sequence directed to the target;
• receiving, by a chamber disposed in the body, combustion gases from the barrel during the firing sequence;
• for each target of the multiple targets in the sequential fashion, receiving, by the feedback control unit, from the sensors the deviation from the respective initial line-of-sight during the respective portion of the firing sequence;
• and
• for each target of the multiple targets in the sequential fashion, controlling, by the feedback control unit, ports in communication with the chamber to vary discharge of the combustion gases from the chamber during the respective portion of the firing sequence to generate forces on the barrel to drive the deviation from the respective initial line-of-sight to the target to a minimum.
