Abstract: A process for making a golf ball includes steps of: a) providing a spherical hollow core which is made from a deformable resilient material, which defines a central chamber, and which includes left and right hemispherical bodies with contiguous circular surfaces having separated upper segments movable away from each other to permit placement of a sensing assembly into the central chamber, b) molding an intermediate shell layer at an elevated temperature that is lower than a softening point of the deformable resilient material to enclose the spherical hollow core, and c) molding a cover to enclose the intermediate shell layer.

Abstract: A method for making a golf ball includes: wrapping a sensing module with a polymeric band to produce a spherical core in which the sensing module is entirely enclosed by the polymeric band; molding a molding material to form an intermediate layer that surrounds the spherical core, wherein the polymeric band acts as a barrier to prevent the molding material from intruding into the sensing module through the polymeric band; and molding a shell to surround the intermediate layer. A golf ball is also provided, and includes a spherical core, an intermediate layer surrounding the spherical core, and a shell surrounding the intermediate layer. The spherical core includes a sensing module, and a polymeric band wrapped around and entirely enclosing the sensing module.
