Abstract: An electromechanical system translates an “aiming error” signal from a target tracking system into dynamic “pointing corrections” for handheld devices to drastically reduce pointing errors due to man-machine wobble without specific direction by the user. The active stabilization targeting correction system works by separating the “support” features of the handheld device from the “projectile launching” features, and controlling their respective motion by electromechanical mechanisms. When a target is visually acquired, the angular deflection (both horizontal windage and vertical elevation) and aiming errors due to man-machine wobble (both vertical and horizontal) from the target's location to the current point-of-aim can be quickly measured by the ballistic computer located internal to a target tracking device. These values are transmitted to calibrated encoded electromechanical actuators that position the isolated components to rapidly correct angular deflection to match the previous aiming error.

Abstract: A method for shooting a projectile weapon involves determining the inclination of a line of sight from a vantage point to a target and a line-of-sight range to the target, then predicting a trajectory parameter at the line-of-sight range, for a preselected projectile.

The method may be embodied in a handheld laser rangefinder including a memory for storing ballistic data. Systems for automatic hold over adjustment in a weapon aiming device are also disclosed.
