Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

Abstract: The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the alteration of the dimple surfaces. In particular, the present invention relates to a golf ball that includes at least a portion of its dimples having circular perimeters and dimple profiles having a concentric groove or a non-concentric groove on the surface of the dimple. The golf ball dimples of the present invention provide golf ball surfaces having unique appearances, while maintaining ideal aerodynamic characteristics.

Abstract: The present invention provides golf balls having a non-straight flight trajectory due, at least in part, to a dimple pattern wherein the dimples on the opposing sides of the ball have at least one design feature that is different.

Abstract: The present invention is a golf ball which comprises dimples having a cross section defined by the superposition of two or more continuous and differentiable functions, and particularly the superposition of a catenary function and a Witch of Agnesi function. Additionally, the dimples preferably have a circular boundary and maintain an axis coincident with the center of the circular boundary.

Abstract: The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the selection of the plan shapes of the dimples thereon. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by low frequency periodic functions along a closed simple path. In addition, the present invention provides methods for designing dimples having a plan shape defined by a low frequency periodic function along a closed simple path.

Abstract: 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.
