Patent ID: 8075431

Claim:
A sporting ball with rotation-dependent enhanced visual acuity, the sporting ball comprising: an exterior having a substantially spherical surface including a first pole directly opposite a second pole and an equator circumferentially intermediate between the first pole and the second pole, wherein the equator is perpendicular to a diameter connecting the first pole and the second pole; a first hub section oriented at the first pole, the first hub section being a first color located at a first position on a CIE (1931) Standard Chromaticity Diagram and having at least one first hub spoke extending spherically outwardly therefrom toward the equator; a second hub section oriented at the second pole on the substantially spherical surface, the second hub section being the first color and having at least one second hub spoke extending spherically outwardly therefrom toward the equator, wherein the first hub section does not overlap the second hub section; an exterior region of a second color located at a second position on the CIE (1931) Standard Chromaticity Diagram that differs from the first position of the first color of the first hub section, the first position and the second position separated by a distance greater than 50% of a chromatic blend limit extending through both the first position and the second position, the chromatic blend limit extending substantially perpendicular to a central confusion line; and an equator comprising the second color, the equator being devoid of the first color comprising regions associated with the first pole and the second pole, wherein the orientation of the first hub section with respect to the second hub section comprises broken circle portions that create a flicker pattern when the sporting ball rotates.
