US Patent:

43758878, Mar 8, 1983

Filed:

May 9, 1979

Appl. No.:

6/037315

Inventors:

Francis deS. Lynch - Mattapoisett MA
Walter L. Reid - Mattapoisett MA
John W. Jepson - Marion MA

Assignee:

Acushnet Company - New Bedford MA

International Classification:

A63B 6936

US Classification:

273 32H

Abstract:

A method of matching a golfer with golf balls with varying aerodynamic properties is disclosed. The "launch conditions" with which the golfer "launches" a golf ball are measured to determine the golf ball dimple pattern most suitble for a particular golfer or to determine modifications which should be made in his style of play or club design.

Jun 26, 1990

Appl. No.:

7/543968

Inventors:

Francis deS. Lynch - Mattapoisett MA
John W. Jepson - Marion MA
Robert A. Brown - Mattapoisett MA

Assignee:

Acushnet Company - New Bedford MA

International Classification:

A63B 3714

US Classification:

273232

Abstract:

A finished, painted golf ball is disclosed. Dimples on the golf ball are interrelated by dimple number, dimple diameter and dimple depth and are arranged on the surface of the golf ball in a manner which enables the golf ball to travel further. At least about 80% of the distances between the closest points of the edges of adjacent dimples are less than about 0. 065 inches and at least about 55% of the distances between the closest points of the edges of adjacent dimples are greater than about 0. 001 inches. Dimple number, dimple diameter and dimple depth are also interrelated in a specific manner according to the formula: ##EQU1## wherein: d=average depth of all dimples in inches D=average diameter of all dimples in inches S=computed unknown (1. 0 or less for present invention) x, y, a and b are dependent on the number of dimples.

Acushnet Company - New Bedford MA

International Classification:

A63B 3714

US Classification:

264219

Abstract:

Dimples are arranged on the surface of a golf ball in a manner which makes the golf ball travel further. At least about 80% of the distances between the closest points of the edges of adjacent dimples are less than about 0. 065 inches and at least about 55% of the distances between the closest points of the edges of adjacent dimples are greater than about 0. 001 inches.

Filed:

Sep 12, 1977

Appl. No.:

5/832563

Paul F. Sullivan - Acushnet MA

International Classification:

H04N 718

US Classification:

358 93

Abstract:

A video data acquisition system takes at least two snapshot views of selected points on a golf ball in the immediate post-launch time period. Analog video data are converted to digital data for analysis in an external system. A trigger generator, of a type well known in the art, senses the existence of a certain set of conditions associated with the launch of the golf ball and thereupon generates a set of precisely timed impulses which trigger the following sequence of events: (a) prepare TV camera to receive data (b) trigger first flash (c) trigger second flash (d) read out data from TV camera.

Assignee:

Acushnet Company - New Bedford MA

International Classification:

G06G 748
A63B 4300

US Classification:

364410

Abstract:

Electro-optical sensors measure the location of a plurality of spots on the surface of a golf club head or a golf ball at a minimum of two precisely spaced points in time. The two time points for the club head are just prior to impact with the golf ball. The two time points for the golf ball are just after impact by the club head. From the apparent displacements of the plurality of spots between measurements, the apparatus determines in substantially real time the velocity of the club head or ball and the spin about orthogonal axes.
