Abstract: In a golf ball colored other than white, the color tone thereof as represented in accordance with the CIELAB color system has an L value of not less than 80, an a value of -30 to +30, and a b value of -30 to +30. The golf ball is preferably colored blue, green, pink, yellow, or orange. Usually, the cover layer of the golf ball is colored in order to color the golf ball. The golf ball does not cause a golfer to feel mental or visual incompatibility while addressing the ball, looks white as viewed from a distance, but looks other than white as viewed at close range to thereby distinguish itself from other balls. Also, the golf ball has improved fashionable features as compared with conventional color balls.

Abstract: A putt training device is provided which preferably includes a body having substantially the shape of a cylinder and a moment of inertia about its longitudinal axis substantially in the range of 79.31 to 84.21 grams-centimeters squared. The body also has first and second substantially flat ends and a substantially continuous outer surface extending between the first and second ends. The body is adapted to be positioned so that substantially the entire continuous length of the body abuttingly contacts a putting surface during rolling movement of the body on a putting surface to thereby provide a visual indication of which position the face of a golf putting club strikes after contact with the body.

Abstract: A system for enhancing the television presentation of an object at a sporting event includes one or more sensors which are used to determine the location of the object. Based on the location of the object and the field of view of a broadcast camera, a processor determines the position of the object in a video frame of the broadcast camera. Once knowing where the object is positioned within the video frame, the television signal can be edited or augmented to enhance the presentation of the object.

Abstract: The self contained flight duration measurement and recording apparatus is designed to be affixed to or contained within an object that will experience a duration of flight. The apparatus will measure and display the elapsed time of the object's flight. A timing device is positioned in a housing. The timing device is activated by acceleration forces on the object and deactivated by the deceleration forces acting upon the object. The force sensing unit that controls the time is an electrical switch that closes momentarily when subjected to inertial changes. The switch has a central core surrounded by a coil, both of which are integrated into a circuit. As the device experiences acceleration or deceleration, the core will contact the coil which will turn on or turn off the timer. Switch sensitivity can be adjusted as necessary for the specific purposes of the device.

Abstract: This system combines television and computer technology to permit one or more golfers to play a highly realistic round of golf from tees to greens. Each golf clubhead has color-coded bars on the rear lower and outer surfaces. As the clubhead approaches the ball it is multiply strobed and the images of the bars recorded on two color TV cameras perpendicular to each other and to the clubhead direction of travel. The resulting TV color images are digitized and transmitted to the computer. The stroke and club data implicit in the images are sufficient to permit computing the ball's total trajectory on the ground and cause it to be projected on the TV screen as the golfer would see it in actuality. The trajectory is superimposed on a TV view of the hole from the golfer's position. The ball's final position on a map of the hole is used to determine the TV view presented on the screen for his next stroke.

Abstract: The present invention provides a putting training apparatus (10) which, when used repeatedly by a golfer, permits him to develop a consistent stroke and accurate putting shot. The putting training apparatus (10) includes a pair of balls (12), preferably regulation golf balls, with a pivotal assembly (16) disposed between the balls (12) which permits relative rotation between the balls (12). The pivotal assembly (16) is positioned along a common axis (24) which passes through the center of the balls (12). The pivotal assembly (16) includes a shaft (30) having opposing ends (43) and at least one bearing (32) proximate to each of the opposing ends (43). A retainer (43') is utilized on each of the ends of the shaft to retain the bearings thereupon.

Abstract: A golf putting practice device comprising a stroke panel and a stance panel, said stance panel adjustably connected to said stroke panel so that said panels are spaced apart in a predetermined relationship, a ball-bell resiliently mounted on the stroke panel and an aperture provided in said stroke panel, in front of said ball-bell, whereby when the ball-bell is struck by a putting stroke it is pushed into the aperture thereby not interfering with the follow-through of the putting stroke.

Abstract: This invention relates to novel shaded logos for use on golf balls, golf balls having said novel shaded logo designs printed on their surface and methods of adding shaded logos to golf balls.

Abstract: A simulated golf ball instructional device for use in practicing golf strokes which has a central body portion and two end portions. Each end portion has a length measured along the longitudinal axis of the device substantially equal to the radius of a conventional golf ball. The device has an overall length between about three and about five times the radius of a conventional golf ball. Satisfactory, improved and preferred overall lengths are disclosed, with the preferred overall length being substantially four times of radius of a conventional golf ball. One or both ends of the device have a generally hemispherical shape. The device is formed of a resilient, porous plastic open cell foam and is free of any covering skin that would substantially impede or prevent the passage of air from within the foam structure out into the space surrounding the simulated golf ball when a distorting force is applied to the device by a golf club.

Abstract: An improved golf ball has navigational band equatorially encircling it over the hall's top, front, bottom, and rear and a non-equatorial alignment band perpendicular to the navigational band midway between the center of the ball and its rear. The respective bands are made of dashed parallel lines subdued but contrasting in color in relation to the color of the ball. At the points of intersection of these bands, two focal points, contrasting from the ball, are formed upon which a golfer, after the ball, the golfer's stance, the club head, and the target have been aligned, focuses attention. A set of directional marks are set within the navigational band and point toward the intended target. The ball is used by aligning the navigational band with the center of the intended target to form a flight path. The club head is then grounded behind the ball in line with the flight path. The golfer uses the club head and the ball as a guide to position his feet in a parallel relationship to the flight path.

Abstract: A golf ball is provided with a marking portion including a hologram implementing a color and/or pattern produced by optical interference. The marking portion is provided on the entire surface of the golf ball or only in dimples. The marking portion including a hologram reflects light and thereby glitters, and is visually recognized as a three-dimensional image, thereby improving visibility of the ball from a distance. The marking portion including a hologram allows an image to be readily reproduced by irradiating a laser beam thereto. Thus reproduced image facilitates an automated inspection for the appearance of the marking portion.

Abstract: A golf training ball comprising at least two cloth stuffed elements each element featuring a sealing point and, stitching to combine the cloth stuffed elements into a unitary ball, where the stuffing comprises a soft fiber, and the cloth elements and stitching are so arranged such that the unitary ball has a core and a periphery with a density gradient between the core and periphery where the golf training ball has a heavier mass in the core and a lesser mass of a soft structure at its periphery to provide a high shock absorbing ability.

Abstract: A striking instrument and struck object monitoring system including at least two shutterable camera units which view a field of view each of which cameras receives light patterns from each and every one of a plurality of contrasting areas on the instrument and the object in rapid successive sequence. A computer receives the signals generated by the light patterns as received by each camera unit which computer discriminates between such signals to determine the instrument's movement and orientation, and the conditions at impact with the object.The striking instrument may be any selected golf club which club is initially scanned by the system to determine it's proper striking location prior to the club being swung through the field of view.
