WIPO Patent Application WO/1996/029124
Kind Code:
A1
Abstract:
A golf game uses radio signals from golf clubs (46) or golf balls (68) to signal a central computer (15) for automatic scorekeeping by the computer. Sensors in each hole (59, 80) send signals to the computer on the completion of each hole of play by each golfer. The golf clubs or balls are distinguishable by the computer according to their radio frequencies or other signal processing or encoding. In the first embodiment, the golf clubs include transmitters which emit radio signals when the clubs are struck against preferably special golf balls, which incorporate magnets or other sensed qualities in their structure. In the second embodiment, the golf balls transmit when struck by special golf clubs which incorporate magnets. Each player, upon starting the game, inputs his/her name or initials to allow the computer to relate strokes to specific players. Scores are reported optionally at each hole, and a final score is reported by the computer at the conclusion of play. A printed copy of each player's score may also be provided.

Description:
AUTOMATICALLY-SCORING GOLF GAME

CROSS-REFERENCE TO RELATED APPLICATIONS

This incorporates U.S. Application Ser. No. 08/408,044, filed March 21, 1995, and a CIP filed January 16, 1996, no Ser. No. assigned. The contents of these applications are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to games of the type having a ball, a plurality of clubs for striking the ball, and holes into which balls may fall, and more particularly to such games with automatic scoring devices.

BACKGROUND ART

Mini golf has been in use for many years, with courses of typically 9 or 18 holes. Scoring is typically done manually by each player, sometimes resulting in arguments between players as to whether the proper score has been written by the player. Players also may lose scorecards or pencils, or may not wish to carry them. There is a need for automatic scoring of each player at each hole and for a central means for reporting scores to the players.

Several U.S. patents are concerned with the field of the invention.

Nicholls et al, U.S. patent 5,354,052, shows a golf course hole-in-one detector. McEvoy, U.S. patent 1,840,406, shows a mechanical stroke counter attached to a golf club. The counter is augmented when a ball is struck.

Reising, U.S. patent 5,370,389, discloses golf balls which include bar codes for identification of the individual balls. Figure 7 shows a computer 118 connected to a plurality of sensors.

Valentino, U.S. patent 5,132,622, shows a golf ball having a metal center which is magnetically detectable.

Wang et al, U.S. patent 5,056,106, shows radio location of golf course positions using different radio frequencies.

Gordon, U.S. patent 3,891,221, shows a magnetic golf ball. The magnetic properties of the ball are not used for sensing.

Jetton, U.S. patent 3,104,879, shows cables running to a central computer from various golf holes having golf ball sensors.

Golf clubs with impact sensors are disclosed by Wilhelm, U.S. patent 4,991,850, and by Allen, U.S. patent 4,940,236. Both employ piezo-electric sensors in the golf club head to register impact against golf balls. The sensors do not appear to distinguish between impacts with golf balls and other objects.

Other U.S. patents are: 5,056,106 to Wang et al; 3,436,076 to Barthol; 3,868,692 to Woodward et al; 4,220,992 to Blood et al; 4,660,039 to Barricks et al; 4,879,651 to Little, Jr.; 4,940,236 to Allen; and 4,991,850 to Wilhelm.

The prior art does not disclose any device which allows automatic score-keeping for each player.

DISCLOSURE OF THE INVENTION

Accordingly, the present invention has an object, among others, to overcome deficiencies in the prior art such as noted above. The invention relates to, for example, a mini golf game, although the invention will work as well in any golf game.

In a first embodiment the invention provides that at the start of play of a golf game, each player keys into a computer keyboard his/her name or initials in conjunction with an identification of a particular golf putting club selected to play the game. All golf balls used for play are coded--magnetically, optically or otherwise--to cause a re¬ sponse when struck by the club, which contains sensors to register when a stroke has been taken. The sensors in the club are connected to a low-power radio transmitter also contained in the club which signals a central receiver in a manner unique to each club, which receiver may be located in proximity to the central computer. Thus, the computer is

capable of receiving and storing the number of strokes taken by the player. Sensors in each putting hole, either optical, magnetic or otherwise, also alert the computer that a ball being played towards that hole has entered the hole, allowing the computer to determine that the player last striking a ball has completed that hole. Displays of the number of strokes taken by each player are located at each hole area, and a final display of the sum of all strokes taken during play is located at the final hole. Also located at the final hole is a printer to print out the score, total as well as hole-by-hole, for each player.

In a second embodiment the invention provides that at the start of play of a golf game, each player keys into a computer his/her name or initials. All golf clubs used for play are coded magnetically or otherwise, to cause a response when striking the ball, which contains sensors to register when a stroke has been taken. The sensors in the ball are connected to a low-power radio transmitter also contained in the ball which signals a central receiver in a manner unique to each ball, which receiver may be located in proximity to the central computer. Thus, the computer is capable of receiving and storing the number of strokes taken by the player. Sensors in each putting hole, either optical, magnetic, weight-actuated, or otherwise, also alert the computer that a ball being played towards that hole has entered the hole, allowing the computer to determine that the player last striking a ball has completed that hole. Displays of the number of strokes taken by each player are located at each hole area, or at a central location, and a final display of the sum of all strokes taken during play is located at the final hole, or at a central location. Also located with the final display is a printer to print out the score, total as well as hole-by-hole, for each player.

BEST MODE FOR CARRYING OUT THE INVENTION: FIRST PREFERRED EMBODIMENT

A plan view of a nine-hole mini-golf course is shown in Figure 1. Each of the golf holes 1 through 9 contain a tee area 10, a fairway 11 and a golf hole 12. The final hole usually contains a target 13, which retains the golf balls for further use. Fairways are typically distorted and/or contain obstructions 14, which test the skill of the

players. A computer 15, with its keyboard 16, display 17, and printer 18 is located adjacent to the tee of the first hole 1. Also collocated with the computer 15 is a receiver 19, with its antenna 20, the function of which will be described below. Adjacent to each golf hole 1 through 9 are displays 21 through 29, wired to computer 15 to display each players' golf score for that hole. A final display 30 gives the total score for each player in their foursome. Golf holes 31 through 39 each contain sensors which are wired to computer 15 to signify the presence of a golf ball in that hole.

Prior to the start of play, each player of a mini-golf foursome (or less) is provided with a golf ball constructed to emanate a weak magnetic field around its spherical area. Several methods of construction of such magnetically- responsive golf balls are given in Figure 2. In Figure 2A, previously magnetized metal rods 40 are imbedded around the spherical area of the ball 41. In Figure 2B, previously magnetized particles 42 are molded between the ball core 43 and cover 44. In Figure 2C, sections of previously magnetized strip 45 are cemented to a golf ball core 43 prior to applying the cover 44.

Each player then selects from one of many golf clubs, putters in the case of mini golf, individually numbered and constructed to transmit a signal from a low powered transmitter actuated when the putter head comes in close proximity to a magnetized golf ball. Each of the many putters is individually coded, by frequency, digital code, or other means, to correspond to the number printed on the top of the club grip. For a 9-hole mini-golf course, for example, at least 36 such clubs would be required if a foursome were playing on each hole. For an 18-hole course at least 72 such clubs would be required.

The construction of the magnetically-activated golf club transmitter is given in Figure 3. Figure 3A identifies the parts of the golf putter 46 as the putting head 47, shaft 48, grip 49, and the numbered plate 50. In Figure 3B, a cross section of the putting head 47 is shown to contain a

cavity 51 which holds a transmitting module 52, a module containing magnetic sensors 53 with impact sensors 54, and a replaceable battery 55, all held in place by a screw-in cover 56. A hole 57 through the top of the putting head 46 allows the transmitter 52 to be connected by a wire to the club shaft 48 which acts as a transmitting antenna. Figure 3C is a schematic diagram of the putting head components. The transmitter 52 is energized through any of a set magnetically-actuated sensing switches 53, each of which is connected in series with an impact sensor 54, and battery 55 to transmit a coded pulse through antenna 48, which is the putting club's shaft.

Figure 3D shows a top view of a putting head 47 at the moment a magnetized golf ball 41 is struck. The weak mag- netic field emanated by the ball 41 closes a magnetically- actuated switch 53, and the ball strike also closes impact sensor 54. This allows transmitter 52 to be connected to battery 55, thus energizing a transmitted signal through transmitter port 57, which connects to the metal club shaft antenna 48. Four (or more) magnetically-actuated switches 53 are used each in series with an impact sensor 54, all connected in parallel, to allow for players' variations in striking the ball at any point along the club face and to accommodate right or left-handed players. The outer material of the putting head 47 is aluminum or hard rubber or any non- ferrous material, with sufficient wall thickness to prevent wall collapse during normal use, while thin enough to allow the magnetic field of the ball 41 to close one of the magnetically- actuated switches 53 and to register ball impact by impact sensor 54.

In addition to the magnetized golf ball and putter- transmitter described above, each golf hole is constructed as shown in Figure 4. The body of each golf hole 58 is built out of plastic or any other non-magnetic material. At the base of each hole, a magnetically-activated switch 59 is located to sense the presence of a magnetically-treated golf ball.

As each player in a foursome (or less) approach the first hole's tee area, the computer display 17 is as shown in Figure 5A, which requests each player to enter their initials and club number via the keyboard 16. When all players have entered their data, the display is as shown in Figure 5B_ informing that group to begin play. The computer 15 is programmed to start scoring for each entered player until a hole sensing switch 38 is closed, which will alert the computer 15 that the player whose last stroke was received on that hole has completed that hole. When all players of a group complete each hole 1 through 9 successively, the displays 21 through 29 at each hole present the display given in Figure 5C. When the final hole 9 has been completed by all players in a group, the final display 30 presents the information of each player's score at each hole, and total score, as shown in Figure 5D. This information is also printed for players retention by printer 18.

A block diagram of components of the Automatically- Scoring Golf Game is given in Figure 6. Computer 15 re¬ ceives inputs from keyboard 16, receiver(s) 19 and each of the hole sensors 38. Golf clubs 46 sense strokes of golf balls 41 and transmit such information 60, each separately coded by frequency, digital code, or other multiplexing means, to receiver(s) 19 for storage by computer 15, and later scoring use. Computer outputs are to the entry display 17, intermediate hole displays 21 through 29, final display 30, and printer 18.

An alternative stroke sensing system is given in Figure 7, where the magnetic ball is replaced with an optically- coded ball using spherically-recognized markings and the club sensing devices are a scanning optical device in conjunction with an impact sensor. For this alternate system, a similar scanning optical device would also be used as the golf hole sensor. One advantage of this alternative is that each ball may then be coded differently, thus allowing unique ball identification with a particular player. All other aspects of the automatically-scoring golf

gam remain the same as given previously.

To further illustrate this alternative, figure 7A gives an example of one of several possible spherically-adaptable optically-recognizable codings which may be imprinted on the ball. The scanning beam width is adjustable to assure that the beam would read the coded lines as well as the spaces between the lines regardless of the ball aspect. The scan angle of the scanning beam may also be alternated between scans to assure that the desired coded line-space separation required by the line reader is maintained for a spherical object. The ball codings and scanner may be either visible or infra-red.

Figure 7B shows the club head construction using this alternative. The battery module and transmitter module are as previously described. The scanning module for this alternative contains a pair of optical scanners 61, one inside each right or left club face, powered by the battery 55, and either used to energize solid state switches 62 connected in series with impact sensors 54, to energize transmitter 52.

Figure 7C is a schematic diagram of this configuration. As the ball is struck, scanner 61 reads the ball pattern,energizing switch 62. Simultaneously, impact sensor 54 registers ball impact and closes the circuit between battery 55 and transmitter 52.

A further alternative substitutes a magnetic pattern coding on the ball and magnetic code readers in the clubs and golf holes. Except for the magnetic vs. optical sensing, the system is identical to that previously described.

BEST MODE FOR CARRYING OUT THE INVENTION; SECOND PREFERRED EMBODIMENT

Prior to the start of play, each player of a mini-golf foursome (or less) is provided with a golf club constructed to emanate a weak magnetic field around its club face area. One method of construction of such magnetically-responsive golf clubs is given in Figures 8A and 8B. In Figure 8A, a

typical golf club 63 is used as a putter. A cross section of the putting head 64 is given in Figure 2B, showing a drilled cavity 65, into which is placed a permanent rod magnet 66. The assembly is sealed with a plug 67. The outer material of the putting head 64 is aluminum or hard rubber, or any other non-ferrous material, with sufficient wall thickness to prevent wall collapse during normal use, while thin enough to allow the magnetic field of the club to cause a reaction in the ball. Each player also receives a golf ball containing a transmitter, whose coding is unique to each ball. For a 9- hole mini-golf course, for example, at least 36 such balls would be required if a foursome were playing on each hole. For an 18-hole course, at least 72 such balls would be required.

The construction of the magnetically-activated golf ball transmitter is given in Figures 9A and 9B. The ball is constructed as two halves of a hollow plastic golf ball, into which are placed the transmitter components. Figure 9A identifies the parts of the golf ball 68 as the low-power transmitter 69, magnetic reed sensors 70, motion sensor 71, battery 72, and antenna 73. In Figure 9B, a schematic diagram of the ball components is given. The transmitter 69 is energized through any of a set of magnetically-actuated sensing switches 70, connected in parallel, then further connected in series with a motion sensor 71, and battery 72 to transmit a coded pulse through antenna 73.

After transmitter assembly, both halves of the golf ball are filled with a non-conducting material to protect the parts against shock and to give the ball the proper weight. The two halves are then cemented together and painted. A symbol or number may then be imprinted on the completed ball to identify its unique coding. External connections for recharging the battery may also be included. Each player receives a golf ball containing a uniquely- coded transmitter, dispensed when the player's name or initials is entered into the system. The ball is dispensed past a magnet, thus triggering a transmission. The central

receiver at the computer site reads the unique coding of the ball and relays this information to the computer to associate each ball with its respective entered name or initials. By this association, the system will have the ability to keep an accurate stroke score for each ball, hence for each player.

Figures 10A-10D describe the golf hole receiving antenna and ball-in-hole apparatus. In Figure 10A, a plan view of the underside of the golf hole carpet or frame, shows the tee area 10, fairway 11, and hole 12. The antenna 74 and ground plane 75 are wired under the carpet or frame to the very low-power transmission from golf balls. Such transmissions are kept at very low power to prevent "collision" with signals from other golf holes, which may confuse the receiver. As Figures 10B and IOC show, an alternative antenna is wired under "bevels" 76, installed at the sides of golf holes. This alternative requires somewhat higher power transmissions, but has the added advantage of easier installation on existing mini-golf courses. The "bevels" 76 also provide the further advantage of preventing golf balls from coming to rest against the sides of mini- golf fairways. It is common practice to use the club to move balls that come to rest against a side wall several inches away from the side so that they can be putted properly. Such action would cause a false stroke to be registered in this system; the "bevels" 76 also eliminate the need for such false strokes. Figure IOC shows a cross-section of the bevel 76, mounted between the golf hole side 77 and the synthetic grass 78 of the fairway. In addition to the magnetized golf club and ball transmitter described above, each hole is constructed as shown in Figure 10D. The body of each golf hole 79 is built out of plastic or any other non-magnetic material. At the base of each hole, a weight-activated switch 80 is located to sense the presence of a golf ball. Alternatively, a permanent bar magnet may be used instead of the weigh -activated switch 80 to cause a second transmission, which can be interpreted by the system as "ball-in-hole" . A

further alternative uses a switch 80 which responds with up to four outputs, depending on weight. Thus, if players do not remove golf balls from holes until several or all of a foursome have completed play, the switch 80 can read each additional "ball-in-hole" activity separately.

As each player in a foursome (or less) approach the first hole's tee area, the computer display 17 is as shown in Figure 11A, which requests each player to enter their initials via the keyboard 16. A ball is dispensed after initials are entered, and the ball's coding is identified to that player. When all players have entered their data, the display is as shown in Figure 11B, informing that group to begin play. The computer 15 is programmed to start scoring for each entered player until a hole sensing switch 80 is closed, which will alert the computer 15 that the player whose last stroke was received on that hole has completed that hole. When all players of a group complete each hole 1 through 9 successively, the displays 21 through 29 at each hole present the display given in Figure 11C. Other congratulatory display messages, such as "NICE SHOT",

"BIRDIE", "WOW", etc., with accompanying sounds may also be added to increase player's enjoyment of the game. When the final hole 9 has been completed by all players in a group, the final display 30 presents the information of each player's score at each hole, and total score, as shown in Figure 11D. This information is also printed for players retention by printer 18.

A block diagram of components of the Automatically-Scoring Mini-Golf Game is given in Figure 12. Computer 15 receives inputs from keyboard 16, receiver(s) 19, and each of the hole sensors 80. Golf balls 68 sense strokes by golf clubs 63 and transmit such information via antennae 73, each separately coded by frequency, digital code, or other multiplexing means, to receiver(s) 19 for storage by computer 15, and later scoring use. Computer outputs are to the entry display 17, intermediate hole displays 21 through 29, final display 30, and printer 18.

The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments, without departing from the generic concepts, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.

INDUSTRIAL APPLICABILITY
