Adaptive golf ball
First Claim
Patent Images
1. A golf ball comprising:
- an inner core;
one or more mantle layers surrounding the inner core; and
an outer cover surrounding the mantle layer(s), wherein the core comprises a magnetorheological fluid comprising a non-colloidal suspension of multi-domain, magnetizable particles having a diameter of about 0.1 μ
m to about 10 μ
m immersed in a carrier liquid, wherein, in the presence of a magnetic field, the magnetorheological fluid experiences a change in viscosity compared to when a magnetic field is not present.

Abstract
The present invention relates to a smart golf ball comprised of one or more mantle layers juxtaposed between an inner core and outer cover, where the core, the mantle layer(s), and/or the cover are further comprised of a ferrofluid, a magnetorheological fluid, an inverse magnetorheological fluid, and/or a magnetorheological elastomer, in any of its construction. These nano-engineered materials make possible a golf ball with heretofore-unprecedented levels of adaptive play.

6. A method of manufacturing a golf ball, said method comprising:
-
providing an inner core, one or more mantle layer(s), and an outer cover, wherein the core comprises a magnetorheological fluid comprising a non-colloidal suspension of multi-domain, magnetizable particles having a diameter of about 0.1 μ
m to about 10 μ
m immersed in a carrier liquid, wherein, in the presence of a magnetic field, the magnetorheological fluid experiences a change in viscosity compared to when a magnetic field is not present;applying the mantle layer(s) to the inner core under conditions effective to surround the inner core with the mantle layer(s); and applying the outer cover to the mantle layers(s) under conditions effective to surround the mantle layer with the cover, thereby manufacturing a golf ball. - View Dependent Claims (7, 8, 9, 10)
