Systems and methods for measuring and classifying golf balls and/or components thereof according to concentricity including automated inspection systems that can simultaneously image multiple golf balls (or components thereof) to gather and analyze data on concentricity and, optionally, classify or sort the multiple golf balls (or components thereof) according to the analyzed concentricity data.

Methods for determining performance information for an object located within an area include obtaining magnetic field information for the area, measuring first magnetic field data when the object is located at a first position within the area, and determining performance information for the object within the area based on the magnetic field information for the area and the first magnetic field data.

A system for selecting a golf ball comprises a ballistics data input configured to receive ballistics data for a plurality of golf balls and for a plurality of launch conditions; a material data input configured to receive material measurement data for each of the plurality of golf balls; a data structure generation module configured to generate a data structure for each of the plurality of golf balls based on the ballistics data and measurement data; an indexing module configured to index the data structures relative to each other; a interactive feedback module configured to solicit and receive launch monitor data and preferences; a modeling module configured to generate a performance model based on the launch monitor data and preferences; and a selection module configured to select one of the plurality of golf balls based on the index and the performance model.

Disclosed is an apparatus for selecting a high-quality golf ball, the apparatus including a measurer configured to transmit a signal toward a golf ball and receive a signal reflected from the golf ball or a signal transmitted through the golf ball; and an analyzer configured to select a golf ball by analyzing the received signal.

A first stamp and a second stamp are printed on the surface of a golf ball such that a transition printed area of the first stamp overlaps a transition printed area of the second stamp to create an overlap printed area between a main printed area of the first stamp and a main printed area of the second stamp. An ink density of the main printed area of the first stamp, an ink density of the main printed area of the second stamp, and an ink density of the overlap printed area are approximately the same after both the first stamp and the second stamp are printed on the surface of the golf ball.

A method and system for determining concentricity of a multiple layer golf ball are disclosed herein. One or more images of a golf ball are generated using an X-ray source, a camera or a digital detector, and an image intensifier. An edge detection algorithm is preferably utilized. The method also includes calculating Y,Z center coordinates of the a best fit diameter or ellipse of the inner edge layer and outer edge layer of the multiple layer golf ball.

The invention provides a device for testing internal pressure of a hollow sports ball; the device comprising: (i) a main body (2); (ii) a removable cap (4); the main body (2) and cap (4) each being provided with mutually engaging formations (12, 14) that enable the main body (2) and cap (4) to be removably secured together by a twisting movement; (iii) a load cell (46) and associated electronic circuitry for processing an output from the load cell (46); and (iv) an electronic display (41) linked to the electronic circuitry for displaying an indicator of the internal pressure of the ball; the main body having an interior void which, together with the removable cap, forms an enclosed ball-receiving chamber for receiving the ball; the interior void of the main body being provided at an inner end thereof with a seat (44) on which the ball can sit, the load cell (46) being disposed beneath the seat (44); and the associated electronic circuitry optionally being disposed below the pressure sensor; whereby the ball-receiving chamber is configured such that when the ball is in place in the chamber, the securing together of the main body and cap brings the main body and cap together in an axial direction to compress the ball and apply a pressure through the ball to the load cell, and a force signal sent from the load cell to the associated electronic circuitry is processed to enable the indicator of the internal pressure of the ball to be displayed.

The present invention generally relates to lightweight, portable robot for analyzing golf balls for short game performance attributes. The preferred robot is specifically designed to be lightweight and portable and to be able to hit a golf ball off of the ground or a mat that simulates the ground such that realistic short game performance can be evaluated.
