Method of Use to Improve Aiming Accuracy for a Firearm

Abstract

A method of using an apparatus that improves aiming accuracy with manually operated firearm provides a means to support the front part of the firearm's barrel and moving the barrel in parallel with the movements of the firearm's butt. Small rotations of the firearm's muzzle are measured by high resolution angular position sensors and rectified by moving the muzzle mount of the apparatus in horizontal and vertical directions which result in rotation opposite to the measured deviation from correct aiming direction, thus preserving the orientation of the manually operated rifle parallel to desired aiming direction.

What is claimed is: 
     
         1 . A method of implementing an apparatus to improve aiming accuracy for a firearm, the method comprises the steps of:
 providing an apparatus with a muzzle mount for a firearm, wherein said apparatus orients said muzzle mount with a yaw axle and positions said muzzle mount with a horizontal translation mechanism;   supporting and aligning said firearm with said muzzle mount along an initial aiming direction;   repositioning said firearm with said horizontal translation mechanism in order to reorient said firearm parallel to said initial aiming direction,   if said apparatus detects an unintentional rotation in said yaw axle,   wherein said unintentional rotation in said yaw axle indicates a horizontal displacement in a butt of said firearm; and   repositioning said firearm with said horizontal translation mechanism,   if said apparatus receives a user input through a horizontal control,   wherein said horizontal control allows for fine manual adjustments to said horizontal translation mechanism.   
     
     
         2 . The method of implementing an apparatus to improve aiming accuracy for a firearm, the method as claimed in  claim 1  comprises the steps of:

 proportionately incrementing or decrementing a horizontal correction counter based on a magnitude and a direction for said user input; 
 comparing a current value for said yaw counter to a current value for said horizontal correction counter in order to determine a value difference; 
 computing horizontal movement instructions in order to reduce said value difference; and 
 executing said horizontal movement instructions with a horizontal actuator, wherein said horizontal actuator controls movements of said horizontal translation mechanism. 
 
     
     
         3 . The method of implementing an apparatus to improve aiming accuracy for a firearm, the method as claimed in  claim 1  comprises the steps of:
 measuring said unintentional rotation in said yaw axle with a yaw angular position sensor; 
 proportionately incrementing or decrementing a yaw counter based on a magnitude and a direction for said unintentional rotation in said yaw axle;

         4 . The method of implementing an apparatus to improve aiming accuracy for a firearm, the method as claimed in  claim 3  comprises the steps of:
 providing a pair of headphones communicably coupled to said external-devices communication unit, said pair of headphones comprises a left speaker and a right speaker; 
 proportionately synthesizing an audio signal in terms of volume for said left speaker, 
 if said unintentional rotation of said yaw axle is in a counter-clockwise direction; 
 proportionately synthesizing an audio signal in terms of volume for said right speaker, 
 if said unintentional rotation of said yaw axle is a clockwise direction; and 
 playing said audio signal through either said left speaker or said right speaker in order to notify about said horizontal displacement in said butt of said firearm. 
 
     
     
         5 . The method of implementing an apparatus to improve aiming accuracy for a firearm, the method as claimed in  claim 3  comprises the step of:
 resetting a yaw counter and a horizontal correction counter, 
 if said apparatus receives another user input through a start/stop control. 
 
     
     
         6 . A method of implementing an apparatus to improve aiming accuracy for a firearm, the method comprises the steps of:
 providing an apparatus with a muzzle mount for a firearm, wherein said apparatus orients said muzzle mount with a pitch axle and positions said muzzle mount with a vertical translation mechanism;   supporting and aligning said firearm with said muzzle mount along an initial aiming direction;   repositioning said firearm with said vertical translation mechanism in order to reorient said firearm parallel to said initial aiming direction,   if said apparatus detects an unintentional rotation in said pitch axle,   wherein said unintentional rotation in said pitch axle indicates a vertical displacement in a butt of said firearm; and   repositioning said firearm with said vertical translation mechanism,   if said apparatus receives a user input through an elevation control,   wherein said elevation control allows for fine manual adjustments to said vertical translation mechanism.   
     
     
         7 . The method of implementing an apparatus to improve aiming accuracy for a firearm, the method as claimed in  claim 6  comprises the steps of:
 measuring said unintentional rotation in said pitch axle with a pitch angular position sensor; 
 proportionately incrementing or decrementing a pitch counter based on a magnitude and a direction for said unintentional rotation in said pitch axle;
