Abstract: A golf ball includes an outer land surface and a plurality of dimples formed thereon. The dimples comprise structures of its surface to energize or agitate the airflow over the dimpled surfaces to increase the aerodynamic performance of the golf ball. These structures may include sub-dimples arranged in various configurations on the dimple. The sub-dimples may have various sizes and shapes. The structures may also include radiating concave or convex arms emanating from the center or a location proximate the center of the dimple. The radiating arms may have various sizes and shapes and may protrude beyond the dimples. By improving the aerodynamic of the airflow over the dimpled surface of the golf ball, the outer land surface of the golf ball may remain robust to prevent premature wear and tear on the golf ball.

Abstract: The invention relates to a golf ball having a core and two or more cover layers. The outer cover layer includes a thin castable material and the inner cover layer a polyisoprene based material.

Abstract: A golf ball with a precise spin rate is disclosed. The distribution of weight among the layers within the golf ball relative to a centroid radius is realized to precisely control the moment of inertia of the ball. In accordance to one aspect of the present invention, the innermost core of the ball is made from a specific gravity reduced material, and a thin dense layer is accurately located either inside or outside of the centroid radius to create a high spin ball or a low spin ball, respectively, with a high compression and soft feel.

Abstract: A golf ball comprising a core and a cover layer wherein the cover is formed of a polyurethane composition comprising a prepolymer comprising a saturated diisocyanate and a curing agent, and an optical brightener.

Abstract: A golf ball with a precise spin rate is disclosed. The distribution of weight among the layers within the golf ball relative to a centroid radius is realized to precisely control the moment of inertia of the ball. In accordance to one aspect of the present invention, a high spin rate golf ball with a dense center, which is positioned radially inside of the centroid radius, and a low specific gravity mantle is provided. In accordance to another aspect of the present invention, a low spin rate golf ball with an inner core and a thin dense layer disposed radially outside of the centroid radius is provided.

Abstract: A method for finishing a golf ball comprising the steps of providing a golf ball having a three-dimensional dimpled surface; preparing the surface for receiving at least one indicia; providing a digital image having at least one color; providing a multi-layered pad-printing substrate having at least one layer; etching the image into the at least one layer of the substrate with a laser; distributing a layer of ink over the etched substrate; providing at least one pad for transferring the ink from the substrate to the three-dimensional surface; and transferring the image from the substrate to the dimpled surface of the golf ball.

Abstract: A method of automatically calculating the spatial relationship of a plurality of diffuse dots on a ball, comprising the automated steps of obtaining at least two ball images of the ball at two or more discrete times; calculating a first gray level of the image; smoothing and binarizing the image; locating and determining the number of ball images in the image; locating and determining the number of diffuse dots on each ball image; confirming that the calculated number of dots equals a predetermined number of dots on each ball image; and calculating movement characteristics of the ball.

Abstract: A solid golf ball comprising a solid core, an encapsulating coating having a thickness of about 0.001 to 0.01 inches and a cast polyurethane outer cover layer. The cast outer cover layer is comprised of a prepolymer and a curing agent, wherein the prepolymer is made from a polyol selected from the group of polyether, polyester and polylactone and a diisocyanate selected from the group of 4,4′-diphenylmethane diisocyanate (MDI) and 3,3′-dimethyl-4,4′-biphenylene diisocyanate (TODI) and toluene diisocyanate (TDI). The encapsulating coating is a thermosetting latex material that is applied to the solid core through a solution.
