US Patent 9151574 Method of movement compensation for a weapon

A method for stabilizing an image and compensating for movement of a weapon is provided, comprising: providing an image stabilization device for an optical scope mounted on a weapon, wherein the image stabilization device includes a sensor to detect motion of the weapon; providing a trigger release device operatively connected to a trigger on the weapon; detecting movement of the weapon by the sensor; generating an output signal from the sensor, wherein the output signal corresponds to the position and velocity of the weapon in a plane perpendicular to the line of sight upon alignment of a feedback reticle with a telescopic sight reticle; processing the output signal to determine an optimal release period, and then generating a release signal during the release period; and using the release signal to activate the trigger release.
