摘要： In an aspect, a sports ball includes a core including a negative Poisson's ratio (NPR) foam material, in which the core has a Poisson's ratio of between 0 and −1, and in which the NPR foam material includes an NPR polymer foam; and a cover layer surrounding the core. In an aspect, a golf club includes an elongated shaft; a grip disposed at a first end of the elongated shaft; and a head connected to a second end of the elongated shaft, the head having a flat face configured for contact with a golf ball, in which the flat face is formed of a negative Poisson's ratio (NPR) foam material, in which the head has a Poisson's ratio of between 0 and −1, and in which the NPR foam material includes an NPR metal foam, an NPR ceramic foam, or an NPR-PPR composite foam.

摘要： The present invention relates to golf balls, specifically to a golf ball comprising an aerodynamic pattern having novel shaped dimple structures which reduce the variation in airflow turning angle thereby improving the golf ball's flight performance. The dimple structures have a conical shaped base with a dimple in the center and reduced or no flat land areas between the dimples.

摘要： Golf balls include dimples for generating a turbulent boundary layer. At least some of the dimples include a fan-shape. The fan-shaped dimple has a plurality of blades. Each blade has a trailing edge flush with a land area of a spherical surface of the golf ball, a leading edge, and a side wall connected to the leading edge. The dimple also has a sloped floor extending from the trailing edge to the leading edge, a blade tip connecting the leading edge to the trailing edge at a distal end of the blade, and a blade root connecting the leading edge to the trailing edge at a proximal end of the blade.

摘要： The present invention is directed to golf balls having improved aesthetics and desirable aerodynamic properties due, at least in part, to the novel shape of the dimples on the surface thereof. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a shape obtained from the intersection of a toroid and a sphere. The resulting curve of intersection represents the dimple perimeter and the intersecting portion of the surface of the toroid represents the dimple surface shape.
