Abstract
A golf ball surface pattern including depressions and protrusions is disclosed and claimed. In one embodiment, the depressions and protrusions are positioned on the ball according to a known dimple pattern, with some of the dimples being replaced with protrusions. In another embodiment, the depressions are positioned on the ball according to a known dimple pattern, and protrusions are positioned on the land areas. Alternatively, protrusions can be positioned on the ball according to a known dimple pattern, and depressions positioned on the land areas. The turbulence generators (dimples and protrusions) that are positioned on the land areas can be positioned manually or with a distribution scheme. In another embodiment, the turbulence generators are positioned according to a scheme based on the principles of electromagnetic theory.
