US Patent 10398955 Ball bat including ball launch angle boosters

A bat customization method includes the steps of capturing images of a batter's swing, determining a swing plane angle of the batter's swing at ball impact at a middle elevation of a strike zone of the batter based upon the captured images, and providing a bat for the batter. The bat has circumferentially spaced launch angle boosters. Each of the launch angle boosters extends along the axis at an angle based upon the determined swing plane angle.
