Smart system for display of dynamic movement parameters in sports and training

Abstract

A system that wirelessly integrates actual golf equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated game of golf. An individual player may opt to play solo or practice to improve basic golfing techniques. The system includes smart golf clubs, a golf ball receptacle and a golf club motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a golf game between two players, via the internet, having similar equipment and remotely located from each other. Standard golf clubs may be retrofitted with the sensors and associated circuitry to convert such clubs into “smart clubs” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

1. Smart Golf Club

[0038] The smart golf club 20 has a head 40 and a shaft 42. As shown in FIGS. 2 and 3, the head 40 has a shaft opening 42, a plurality of embedded contact sensors 46 (three are illustrated in the preferred embodiment), and the internal electronics circuitry 48 including a wireless radio frequency transmitter (58 in FIG. 5). As shown, at least one of the sensors 46 is located at or proximate to the optimal location on a club face 47 for contact with the golf ball, the “sweet spot” 49. The remaining two sensors are adjacent and on either side of the sweet spot 49. The contact sensors may be, but are not limited to sensors employing piezoactive type transducers, specifically, either piezo-electric or piezo-resistive transducers (similar, but is not limited to the Cooper Instruments LPM 562).

[0039] In an alternative embodiment, FIG. 3A, three sensors 46 are applied to the face of an adapted club by a Mylar tape or other means 49. Again, the electronic circuitry is internal to the club head 40 and connects to the sensors 46 by leads 27.

[0040] In a second alternative embodiment, to retrofit a standard golf club, contact sensors 46 are part of an adapter 40 attached to an ordinary club head as seen in FIG. 4 and wire connected to an electronic circuitry 48 attached to the club shaft 42 or elsewhere on the club.

[0041] A golf ball contacting any sensor 46 produces a detectable variance indication the magnitude and duration of sensor-ball impact. The variance may be a change in resistance of a piezo-resistive transducer or a voltage change in the case of a piezo-electric transducer. As shown in FIG. 5, the variance is detected and amplified by an associated amplifier 52 and is the input to an associated integration circuit 54, the output of which represents the energy of the ball-club contact event. Connected to the integration circuit 54, a microprocessor 56 is a multi-input signal processing circuit (similar, but not limited to a Motorola #68HCO5) having analog to digital signal converting circuits (ADCs), one for each input channel, and a sequential digital signal encoding circuit connected so as to convert the ADC outputs into a time multiplexed serial digital data stream containing a binary-coded word for each channel indicating the energy of the associated sensor-ball impact event.

[0042] A radio frequency transmitting circuit 58 receives the serial digital data from the microprocessor 56 and wirelessly transmits the information via an internal antenna 60 to a receiver 26 (FIG. 1) for subsequent processing by the computer 28.

2. Golf Ball Receptacle

[0043] The golf ball receptacle 22 has a top 62 shaped to allow entry of a golf ball, as shown in FIGS. 6A, 6B, and 6C. The receptacle has a contact sensor pad 64, shown in FIG. 7, containing at least one contact sensor (three different activation areas 65, 66, and 67 are illustrated in the preferred embodiment), a ball return mechanism 69 (FIG. 6B) and internal electronic circuitry 68 (FIG. 6B). The internal circuitry includes a wireless radio frequency transmitter (not separately shown in FIGS. 6A, B and C). As shown, the preferred embodiment has contact sensor pad 64 positioned within the receptacle 60 such that the center activation area 66 aligns with the center of a ball entry 70. Additional sensor activation area 65 and 67 are adjacent, one on either side of the center area 66. In the preferred embodiment, of FIGS. 6A, 6B, and 6C, and like the sensor used at the face of the club, the sensors may be, but are not limited to, sensors employing piezo-active type transducers, specifically, either piezo-electric or piezo-transducers.

[0044] A golf ball entering the receptacle 60 and containing the sensor pad 65, 66 or 67 produces a detectable variance indicating the ball entry event. The variance may be a change in resistance in the case of a piezo-resistive transducer (similar, but not limited to Cooper Instruments LPM 562) or a voltage change in the case of a piezo-electric transducer. As illustrated in FIG. 8, the variance is detected and amplified by an associated amplifier 71. The amplified signal then is input to a microprocessor 72 having an analog to digital signal converting circuit (ADC) and a digital signal encoding circuit connected so as to convert the ADC output representing the sensors signals into a serial digital data stream containing a binary coded word indicating the sensor-ball contact event. The microprocessor 72 may be the same or similar to the microprocessor 56 of the golf club electronics. A radio frequency transmitter circuit 74 receives the serial digital data from the microprocessor 72 and wirelessly transmit' the information via an internal antenna 76 to the receiver 26 (FIG. 1) for subsequent processing by the computer 28.

[0045] The ball return mechanism 68 can be simple as a back plate 80 located to be engaged by a golf ball entering the receptacle 22 and supported and biased by a spring or springs 82 to eject the ball. Other known ejection devices, similar to those used in pin ball machines and either mechanically or even electrically activated, can be used to improve the effect if desired.

[0046] The receptacle configuration is susceptible to much variation. The receptacle illustrated and described above is well suited to indoor use, on carpet for example. It is clear, however, that an actual cup, installed in an actual green, with real or synthetic grass, can be similarly equipped.

3. Golf Club Motion Sensor Plate

[0047] The golf club motion sensor plate 80 having a top motion plate 82 and a bottom motion plate 84 is diagrammatically shown in FIGS. 9A-D, wherein the top motion plate 82 contains a plurality of capacitor-forming electrically isolated platelets 83 (twelve platelets are illustrated in this exemplary preferred embodiment). They are evenly distributed at or just below the top plate's exterior upper surface 82. The bottom plate 84 has a homogenous electrically conductive interior surface 85 underlying the platelets 83. Each capacitive platelet 83 contained in the top motion plate 82 forms a capacitive component when the top and bottom motion plates are vertically closely spaced to form the golf club motion sensor plate. A suitable insulator may be sandwiched between the two plates. The structure is adhesively or otherwise mechanically joined and it may be covered or coated as desired. The result is a golf club motion sensor plate 80 containing a capacitor matrix (a 3×4 capacitor matrix is illustrated in the preferred embodiment0. The capacitive components 83 are connected to form a capacitive network 88 as is indicated in FIGS. 9E.

[0048] Applying an energizing high frequency alternating electrical signal having a frequency in the range from 100 MHz to 200 MHz from an oscillator 87 to the golf club motion plate capacitive network 88 produces an electromagnetic field above the surface of each platelet 83 of the capacitive components of the motion sensor plate 80. Any object, including a golf club, passing near the surface of the energized motion plate will cause a perturbation of the electromagnetic field as illustrated by the sample possible pathways 90 across the plate in FIG. 9C. A network 92 of electrical comparator amplifiers (FIG. 9B) is connected to the capacitor network. The comparators of the network 92 are connected one to one with the capacitive elements of the capacitive network 88. The comparators of the network 88 detect voltage variations occasioned by electromagnetic field disturbance due to a golf cub moving over certain of the capacitive elements of the motion plate. Each different golf club motion over the energized motion plate will produce a uniquely identifiable signal from the comparator amplifier network. There are a variety of known proximity sensors that could be gathered together in an array like that of the platelets 83 to serve as the transducer portion of the golf club motion detector.

[0049] The electrical signal from the comparative amplifier network 92 is applied to an analog to digital signal converter 94 (ADC) and the ADC digitized output signal is converted into a serial digital data stream by a multiplexer 96. This data identifies each platelet having had its field disturbed. The serial digital data can be input directly by wire from a multiplexer 96 to the computer 28 located at the site of the golf player and golf club motion sensor plate 80, or as in the preferred embodiment, illustrated in FIG. 1, the serial data can be transmitted 100 and an antenna 102, included in the golf club motion electronic transmitter communication circuitry from FIG. 1.

[0050] The computer 28, under the control of the golf system software, will analyze the serial digital club motion signal, recognize from the transmitted signals the platelets 83 over which the club head passed and display the golf club swing motion.

4. Wireless Signal Receiver and Computer

[0051] At each player site, a wireless radio frequency signal receiver 26 is connected to the computer 28 by either the serial (USB) or parallel computer ports, as shown in the functional block diagram, FIG. 10. The wireless signal receiver 26 detects digitally coded radio frequency transmissions from the communication circuit associated with any of a smart golf club 20, a golf ball receptacle 22, or a golf club motion sensing plate 24, as shown in FIG. 1. The received transmission are demodulated by the RF receiver circuitry 122 (FIG. 10) connected to a microprocessor 124, which converts the demodulated data signal to serial binary coded data suitable for communications to a computer 28. The computer 28, under the control of the internally installed golf system software program, monitors and directs the flow of communications between remotely located players via the internet and displays the game simulations and performance information. In appropriate installations the wireless electromagnetic signals that communicate with the receiver may be infrared communications.

5. Computer Golfing Software

[0052] At each remote player site, the computer 28 (FIG. 1) under the control of the golfing software program (shown in the golfing software system functional block diagram, FIG. 11) monitors and control initialization and the sequential play of the golf game, or alternatively, the individual player practice session. Upon start up by a player at a particular site, the system input parameters are set and the system internet and player port interfaces are initialized 130 as indicated by the arrows 130a and 130b. For internet communications, the serial port listener of the computer 28 is enabled in the preferred embodiment. A remote player event listener is initialized. It will communicate events from one or more of the smart golf club, the golf ball receptacle and the motion sensor plate. The main operational software (program) thread is run 130, and the system awaits data input from the appropriate computer communications ports at 132 (port), 133 (Remote player Socket Event Listener).

[0053] If the competitive play mode has been selected, the program generates a player participation request and sends 134 the request to the GGC game internet server (GGC server) 34 (FIG. 1). Upon identification of a player opponent at 150 (FIG. 12) by the GGC server, the program initiates the player identification sequence 152 and sequential play begins 154 (This software sequence and control routine occurs at each remote site where play has been initiated. During the game play sequences 154, the program generates the appropriate animation, display, and audio data and commands 136 and 138 (FIG. 11), and communicates with the associated display and speaker devices 30 and 31 (FIG. 1). Upon the occurrence of a local player event, detected at 133, the main operating program at 130, displays the event at 136, and communicates the event at 132 by causing a device transmission at 137 to be send at 134 via the internet GGC server 135 which displays the event for the opposing player and alerts the opposing player it is his/her turn to play. The local player event may be, but is not limited to the smart golf club impacting a ball, the swing of a club across the sensing plate or the balls entry into the receptacle. The program contains time delay limits for the player action, and delays of play beyond these limits generate play quit and disconnect signals.

[0054] The event at 133 also has the effect of indicating at 139 that it is no longer the local players turn and enables (as indicated by line 139) the serial port listener at 132 to detect an event from the remote player, again via the internet.

[0055] If the single player practice mode is selected, the internet communications sequences are disabled, other software sequential operating routines continue as above described and the players golf club stroke, ball-receptacle contact, and/or club swing motion sensor information are communicated only to the computer located at the players site and the performance information analyzed and displayer only at the local players site.

[0056] When a game is won, lose, or terminated, the golf software system generates the appropriate output signals 156 (FIG. 12), displays the player performance information, and resets to initial pre-game conditions. If one player opponent quits the game or is “timed out” (due to excessive delay in play) and the remaining player wishes to continue play, the software resumes an internet search for another opponent 152 and 153.

[0057] Using programming as contained in the accompanying microfiche appendix, one skilled in the art can readily accomplish the game programming described. Alternative programming too will be apparent from the foregoing functional description and the illustrations contained in the appended drawings

[0058] While a preferred embodiment has been described, it will be appreciated that many variations and modifications in the system, its operation, and its various components may be made without departure from the spirit and scope of invention as set forth in the appended claims.
