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.

Claims

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 inner core is further comprised of a permanent magnet immersed in a ferrofluid, and the ferrofluid is further comprised of a colloidal suspension of nanometer-sized, single domain, magnetic particles immersed in a carrier liquid.

2. The golf ball according to claim 1, wherein the magnetic particles comprise ferromagnetic or ferrimagnetic substances.

3. The golf ball according to claim 2, wherein the ferromagnetic or ferrimagnetic substances are selected from the group consisting of iron, cobalt, nickel, magnetite, maghemite, cobalt ferrite, manganese ferrite, carbonyl iron, and combinations thereof.

4. The golf ball according to claim 1, wherein the carrier liquid is selected from the group consisting of water, animal oil, mineral oil, vegetable oil, synthetic oil, petroleum oil, petroleum distillates, alcohol, glycol, glucose, and combinations thereof.

5. The golf ball according to claim 1, wherein the carrier liquid further comprises anti-oxidizing, anti-corrosion, anti-wear, anti-agglomeration, and/or anti-settling agents.

6. The golf ball according to claim 1, wherein the magnetic particles have a diameter of about 2 nm to about 10 nm.

7. The golf ball according to claim 1, wherein the permanent magnet is magnetically-levitated and self-centered within the ferrofluid.

8. The golf ball according to claim 1, wherein the permanent magnet has a spherical shape.

9. The golf ball according to claim 1, wherein the permanent magnet comprises a material selected from the group consisting of Alnico, NdFeB, SmCo, FeCrCo, BaO:

Fe₂O₃, SrO;

Fe₂O₃, MnO;

Fe₂O₃, PbO;

Fe₂O₃, Nd₂Fe₁₄B, Sm₂Fe₁₇N₃, Sm₂Co₁₇, SmCo₅, BaFepO₁₉, and combinations thereof.

10. 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 inner core is further comprised of a permanent magnet immersed in a ferrofluid, and the ferrofluid is further comprised of a colloidal suspension of nanometer-sized, single domain, magnetic particles immersed in a carrier liquid;

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 layer(s) under conditions effective to surround the mantle layer(s)with the cover, thereby manufacturing a golf ball.

11. The method according to claim 10 further comprising:

effecting a magnetic interaction for purposes of facilitating golf ball manufacture.

12. The method according to claim 11, wherein the magnetic interaction is effected by using one or more permanent magnets.

13. The method according to claim 11, wherein the magnetic interaction is effected by using one or more electro-magnets.

14. The method according to claim 11, wherein said facilitating comprises handling, sorting, storing, packaging, labeling, picking, and/or placing of golf balls.
