Method for incorporating a tracking device within a body of elastomeric material, including the steps of: a) providing a semi-finished product made of a raw elastomeric material, preferably rubber or a thermoplastic polymer; b) providing a tracking device; c) providing an insert; d) joining by means of textile technique the tracking device and the insert so as to obtain a trackable insert; e) providing a mould; f) inserting the semi-finished product and the trackable insert into the mould; h) obtaining a trackable body by moulding the semi-finished product together with the trackable insert.

Golf balls and golf ball components made using three-dimensional (3D) additive manufacturing systems are provided. The golf ball includes at least one three-dimensional piece. Preferably, a continuous liquid interface printing method is used to make the three-dimensional structure. Ultraviolet (UV)-light polymerizable materials are used in the method. The method may be used to make single-piece or multi-piece balls. For example, the ball may include an inner core produced by the liquid interface printing method. An outer core layer may be disposed about the inner core, and a cover comprising inner and outer cover layers may encapsulate the core assembly to form the finished golf ball. The outer core and cover layers may be made using conventional molding technologies or the methods of this invention.

The invention relates to a golf ball (1), which has at least one transmitting and receiving antenna (10) and a position determination unit (11), which has a communicative connection to the transmitting and receiving antenna (10) and is designed to receive GPS data, which specify the position of the golf ball (1). Furthermore, the golf ball has a communication unit (12), which has a communicative connection to the transmitting and receiving antenna (10) and is designed to transmit radio data, in particular the position of the golf ball (1). In addition, the golf ball has at least one charging coil (14), which is connected to an energy store (13) and is designed to charge the energy store (13) by means of inductive energy transmission. Moreover, the invention relates to a method for locating an object, in particular a ball-like object, for example, a golf ball, and a transmitting and receiving antenna for use in such a ball-like object.

Systems and methods for tracking a sports object are provided. A sports object includes a core assembly arranged within a shell and having multiple components to receive and transmit signals corresponding to movement of the sports object, as well as to support operational tracking of the sports object. The core assembly includes a multi-layer printed circuit board (PCB) comprised of a plurality of sections. The PCB is configured to at least partially envelope the energy storage device at a geometric center of the assembly. The PCB is connected to one or more antennas (e.g., via one or more contacts), which may be arranged on one or more sections of the PCB, arranged on a surface of the shell, and/or in a volume within the shell.

A golf ball has a cover and a core surrounded by the cover. The core has an inner core and an outer core. The inner core is formed from a first composition and has a generally spherical shape and a spherical surface. The inner core has one or more blind holes that each extend from an opening at the spherical surface to a depth within the inner core. The outer core is formed from a second composition, different from the first composition. The outer core has a first portion that surrounds the inner core and a second portion that extends into each blind hole and thereby fills each blind hole of the one or more blind holes.
