  • Patent number: 7651408
    Abstract: A method and apparatus for beneficially controlling the impact between a club head and a golf ball are described. A golf club head (such as on a driver, iron, or putter) has a body and a face mechanically supported thereon, wherein the face and body are elastically tailored to create beneficial face motion and deformation at impact. The tailored clubhead compliance is shown to influence impact properties and resulting ball parameters such as speed, direction and spin rates resulting from the impact event between the face of the club and the golf ball. Several embodiments are presented for controlling ball spin through design of the elastic and dynamic response of the face and body under impact loading.

  • Patent number: 7572196
    Abstract: The present invention relates to a dampening device for ball game rackets. The dampening device of the present invention includes at least one dampening element having a foot or base region, a head region and a neck or connection region arranged between the foot region and the head region. The provision of a neck or connection region leads to an optimum distance between foot or base region and head region and/or an optimum and safe positioning of the head region in the stringing plane at a preferred distance from the heart region of the racket. Preferably, the neck region is tapered or necked relative to the foot or base region and/or the head region at least in the width or thickness direction of the dampening device of the invention.
