Description
CLAIM OF PRIORITY
[0001] The present application is a Continuation-in-Part of U.S.
patent application Ser. No. 12/386,191, filed Apr. 15, 2009,
entitled Automatic Real-Time Game Scoring Device and Gold Club
Swing Analyzer, which claims priority of U.S. Provisional
Application Ser. No. 61/195,857 filed Oct. 10, 2008 entitled "GOLF
SWINGER" the teachings of which are incorporated herein by
reference.
FIELD OF THE INVENTION
[0002] The present invention is generally directed to golf club
devices, and more particularly to game performance tracking and
swing analysis.
BACKGROUND OF THE INVENTION
[0003] The game of golf is complex given the numerous elements that
affect a golf shot. The basic physical properties include the
properties of the golf club, the ball, as well as the ball lie and
weather conditions. The more complex aspects involve the golf swing
and the ball strike, which are the subject of detail analysis by
golf instructors, as well as equipment designed to analysis a club
swing.
[0004] Due to the aforementioned complexities even the simple act
of accurately detecting a golf shot allowing for automatic scoring
has not been reliably achieved, therefore, to this day a round has
required manual input from the golfer. Such a requirement often
leads to inaccurate scoring, distraction from the game, and loss of
enjoyment.
[0005] An important aspect in improving one's game of golf is a
need to be able to review the cause-and-effect relationships that
result during each and every swing. Again considering the
complexities mentioned above this can only be done accurately
during actual play. The basic factors of such an analysis may be
the club used, the distance the ball traveled, the effects the
swing had on the ball travel (such hook or slice), and the
hole/golf course in which these results occurred. This
cause-and-effect relationship ultimately is the result of the
golfer's club speed, swing profile, body/head positions and other
parameters throughout the swing.
[0006] While some of the swing analysis methods utilized by Renee
Russo in the movie Tin Cup may not possess practical value, more
complex devices utilized to ascertain/estimate swing parameters
during practice can be found at local golf instruction centers.
However, these complex swing analyzers are not suitable for use
during golf play on an actual course. Moreover, these analyzers do
not provide statistics of an actual golf shot during play, and as a
function of real world conditions.
[0007] When data is obtained in real-time it may be necessary to
provide power to the devices obtaining such data and transfer
information between devices, which devices may be physically
independent but acting as a system during data collection.
SUMMARY OF INVENTION
[0008] The present invention achieves technical advantages as a
device and system utilizable during actual golf game play
configured to obtain information related to a player's golf swing.
This information may include information generated by a sensor
located within a golf club and received by a golf appliance, such
as a golf glove. These sensors provide data to facilitate assessing
a player's swing as a function of ball strike; club used; and swing
velocity and profile as a function of real world conditions.
[0009] One aspect of the invention includes the capability to
supply all of the power required to the sensor to obtain real-time
data from a sensor(s), such as a microprocessor, or other
components located within the club.
[0010] In another aspect of the invention power is applied to both
charge batteries or super capacitor (s) incorporated within the
system and to a power a microprocessor or other components.
Providing for small capacity batteries or super capacitors to be
used within the golf club provides for additional data collection
and storage when the club is not in contact with the glove.
[0011] In yet another aspect of the invention the data collected
from sensors may be in an analog or digital form.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0036] Referring to FIG. 1 a typical golf club 100 is represented.
Shown also in FIG. 1 is the addition of a device that may include a
swing detector 200 attached to golf club 100, shown in this
embodiment at the top of the club's grip 102 in one preferred
embodiment of the invention. The detector 200 is configured to
detect an actual golf shot event, such as detecting the shaft 104's
motion and/or vibrations, such as a resonant frequency indicative
of a ball strike or a jolt, or a sound indicative of an actual ball
strike during golf play. The detector 200 may include an
accelerometer and or other sensor elements configured to detect an
actual golf swing and/or ball strike. The detector may be located
at another location on or in the club, or integrated with the grip
as desired. The detector 200 is configured to generate a signal
indicative of an actual ball strike during the actual play of
golf.
[0037] FIG. 1 also shows for illustration a ball 110 that may have
a path 112 when struck by the club, a playing surface 114, a divot
116, a club head swing path 118, and a club head backswing path
120.
[0038] Shown in FIG. 2 are multiple detectors 200, one for each
club, each configured to sense an actual swing and/or golf ball
strike for the specific type of club, whether it be a driver 218,
iron 210, or putter 202, that are each club mounted. Each detector
200 shown is configured to transmit data indicative of a golf ball
strike, and/or golf swing characteristics, back to a
reading/processing device 306 via link 308, such as display/scoring
unit 600, which may be worn by golfer 302, or via link 310 to a
remotely located device, such as in a golf cart 314 as shown at 316
in FIG. 3. The data transmitted may be responsive to a signal
generated by unit 500, or may be automatically sent without
prompting.
[0039] In various other preferred embodiments, different points of
attachment of the detector 200 may be used, such as next to the
club grip and directly onto a club shaft at 208, or within the club
shaft itself at 206. The detector can also be mounted near a club
head at 204 and 214, such as the club hosel, or internal to the
club near point shown at 212. Although FIG. 2 shows different
points of attachment on the three clubs represented, the specific
points shown may be used on any of the clubs.
[0040] During a club swing, the golfer performs a slow backswing of
golf club 100 in the direction indicated by 120. At the pinnacle of
this action the direction is reversed and with the aid of the body
movements the club head is accelerated in the direction indicated
by 118. During this action different results may occur. The golf
ball 110 may be struck directly, or the ground 114 may be lightly
stuck before hitting golf ball 110. Other results such as the
ground 114 being stuck in a manner that results in a divot removed
at 116 may occur, after which the golf ball 110 may or may not be
hit by the club head 108. Additionally, it is conceivable that the
golf ball 110 is missed completely by the club head 108.
[0041] Regardless of which of the above actions takes place, the
club head 108 will continue in some manner in the direction
indicated by 112. Due to the amount of variables in the actions
resulting from a golf club swing, the speed of a club head, and the
similarity from one swing to the next, it is desirable for an
automatic golf scorer that is capable of detecting and/or analyzing
these variables to provide practical information as well as one
that is portable, enabling its use during actual play.
[0042] While various approaches may be employed to detect the
contact of a golf ball 110 and club head 108, they may be
intrusive. Any device mounted or adhered to the face of club head
108 may affect features that are designed into the head to aid in
spin and momentum transfer to the golf ball.
[0043] Other devices/sensors may mount at an area of the club
likely to provide the greatest amount of feedback to a detection
device, such as at point 214. Mounting a device in that location
may affect the actual swing characteristics of the club itself,
potentially altering the swing weight or resistance to the air, or
just the fact that the golfer may perceive that such an affect
occurs.
[0044] In yet another preferred embodiment, referring to FIG. 3,
the detector 200 may be incorporated into/onto a glove of golfer
302 as shown at 305 and described later in reference to 806 and 822
shown in FIG. 8, wrist mounted in a player attachment/accessory
312, or incorporated into a watch 304.
[0045] In embodiments where the swing detector 200 is not
physically attached to the club, the detector is configured to
sense parameters indicative of the club swing and/or an actual ball
strike. In a preferred embodiment each club has an ascertainable
indicator that is indicative of the club. Identification may be
made by reading an RFID code, by sensing a resistance indicative of
the club, or some other method.
[0046] RFID tags may be designed in many physical configurations.
For the above embodiments described wherein the swing detectors are
not physically attached to each club, a properly shaped RFID device
may be utilized in some of the locations previously discussed with
swing detector 200. For example, a small circular RFID tag may be
attached at 216, shown in FIG. 2C, or a larger rectangular one may
be placed under or near a golf club grip such as at 206.
[0047] One embodiment of detector 200 is shown as detector 400 in
FIG. 4. This detector 400 may be detachably mounted to clubs. This
detector may also be selectively changed from club to club if
desired. Shown in FIG. 2 is this detector mounted at 216 onto a
driver 218, and at 208 mounted onto an iron 210. Other locations
for this embodiment can be at 204 and 214. The detector 400 has a
processor, such as a microprocessor, as well as supporting elements
including memory and a data interface.
[0048] Detector 400 may also be mounted internally at points such
as 206 and 212 shown in FIG. 2B on iron 210. It is contemplated
that similar mountings and variations may also be used on putter
202 and driver 218.
[0049] Dependant on the preferred embodiment, the present invention
advantageously detects both the club swing and actual ball hit.
Additionally, it differentiates the actions that result in the
incrementing of a stroke to the score, from those actions that do
not, such as practice swings and divots.
[0050] As seen in FIG. 4, one embodiment of detector 200 is shown
as detector 400 and may be attached directly to each club. Detector
400 includes a microprocessor 408, such as a Microchip technologies
12F683 or 16F883 configured to evaluate inputs from sensors 1 and 2
(402 and 404, respectfully), where such sensors may be
accelerometers detecting positive and negative swing accelerations,
and/or club angles, club vibration (such as a vibration frequency),
or a step function delta indicative of a ball strike. One of the
sensors may be used to provide additional feedback, such as a sound
profile of the ball hit itself, or visual or sonic feedback of the
golf ball itself.
[0051] Also shown in FIG. 4 is a timer 410, wherein the input
signals received from the sensors and the timer are analyzed by
processor 408 and compared to characteristic profiles stored in
memory 412 indicative of many different types of events that may
occur. For instance, the time between initiation of a back swing
until a ball strike can be correlated with other input, such as a
club type, to determine actual club swing parameters. These club
swing parameters are then transmitted back to unit 500 where
additional analysis may be performed in real time, or at a later
time, such as when the data is downloaded to a PC for later
analysis. Transceiver 406 may be part of processor 408 or separate.
Transceiver 406 is a low power short range device with a specific
identification code and may be of the RF type, Bluetooth, or
another transmission method.
[0052] FIG. 5 is a block diagram of another embodiment of swing
detector 200 shown as detector 500. Microprocessor 508, timer 510,
sensors 1 and 2 labeled 502 and 504, respectfully, memory 512, and
transmitter 506 may be utilized as described above for detector
400, or in a different configuration. This embodiment is configured
to be worn by the golfer as shown in FIG. 3 as 304, 305, or 312.
The detector 500 may also have a display 514 shown as 304
configured to generate a visual event indicative of the swing or
ball strike. Moreover, the detector 500 may include an RFID
interface 516 configured to receive RFID signals from a club, such
as indicative of the club used during a swing and ball strike.
Aside from an RFID device, an alternative method may be used for
identifying each club, such as a resistance discrimination method,
wherein each club has a unique resistance characteristic such as in
the grip, detectable by golf glove 804 and shown worn by golfer 302
as 305. Additionally, other club identification means could be
employed as recognizable by those skilled in the art.
[0053] Detector 500 may also include a low power short range device
with a specific identification code and may be of the RF type,
Bluetooth, or another transmission method to communicate
information to a display/scoring unit, such as unit 600 or unit
700, as similarly done in device 400, shown here as an RF interface
or wireless interface 516. A GPS receiver 518 may also be
incorporated or the transceiver means used to communicate with a
separate GPS device.
[0054] FIG. 6 is a block diagram of the user worn display/scoring
unit 600. This unit partially consists of a microprocessor 604 such
as a Microchip Technologies 18F6393, timer 612, and micro display
610. Information/data is received by transceiver 606 from a single
club, or even multiple clubs, with embedded detectors. For the
embodiments where the clubs do not have these detectors,
information may be received from body mounted swing detectors, such
as those shown in FIG. 3 at locations 304, 305, or 312.
Additionally, a physical contact glove detector may be used as
described later in an additional embodiment. The unit 600 receives
the data from the user worn glove transceiver/detector, such as
that shown in FIG. 8 at location 806 or 822. Due to the many
embodiments it is important to understand that a user worn
display/scoring unit such as that shown as 304 in FIG. 3 may also
incorporate a swing detector, therefore, similarities as well as
differences are explained in both the descriptions of units 500 and
600.
[0055] Algorithms in processor 604's embedded code perform
additional analysis on this information/data. One preferred
embodiment incorporates a GPS receiver 608, while another
embodiment having at least one sensor 602 determines game scoring
by using and/or correlating the profiles and methods outlined in
Tables 1 to 3. For example, the length of time between golf club
swings, which club was last used, the changing of a club, and
vibration data, such as a traveling profile described in Table 3.
This data and the method algorithms may be used to determine that
one hole is completed and a new hole is being approached and adjust
the stroke count appropriately.
[0056] FIG. 7 is a block diagram of the cart display/scoring unit
700 having at least one system including wireless interfacing, such
as an RF interface 702, and may have additional data communication
means 706 such as, but not limited to, Bluetooth, Wireless
Internet, Cellular, or USB. This unit partially consists of a
microprocessor 704 and timer 714 and display 708. Information/data
is received by a transceiver/wireless interface 702 in real time
from body mounted swing detectors, such as those shown in FIG. 3 at
locations 304, 306, or 312.
[0057] Transceiver 702 communicates with the multiple swing devices
200 while transceivers 702 and/or 706, additionally, may be used to
receive code and profile updates, or download the results stored in
unit 306 and 316 to a PC or other devices such as a PDA, in real
time via a data link, or at a later user defined time. Using
transceivers in place of transmitters allows for additional
functionality. For example, the individual profiles and sensor
characteristics can be updated, or swing device data communication
could initiated by request or polling, such as initiated by remote
display/scoring unit 306 or 316. Such improvements may result in
longer life to batteries in sensor 200, not shown in these
diagrams.
[0058] FIG. 7 also shows an embodiment where additional memory may
be included. This memory can be interfaced to directly from an
integrated memory controller 710 contained within a
microcontroller, such as a Microchip technology PIC 18F8493. An
advantage of this embodiment is that wireless data may be
communicated amongst other teams such as in a tournament play.
Additional memory also allows multiple players to have ready access
to a great amount of historical play information previously
obtained by the automatic analysis system being described herein.
An instance of such data may be a data screen selection displaying
information on selecting your golf club based on an analysis of the
distance required and the average distance hit with various clubs
that day and/or historically. An additional use may be to select a
screen display that provides recommended changes to your golf swing
based on how you are hitting the ball that particular day (e.g. you
are slicing to the right, please try to do . . . , your
acceleration is too slow, try picking up golf speed, etc.)
[0059] Advantageously, the display/scoring units described herein
as units 304,306, 316, 600, and 700, release the user of the burden
or trying to remember a lot of details during game play, but can
rather rely on the data now immediately available to make
adjustments to one's game play during the game. Frustration is
reduced because a golfer does not have to wait until the next game
to consider how to improve one's game. By knowing that one is
hitting the 7 iron well, for instance, one may choose that club
over a 6 iron if one knows that he/she is hitting it better.
[0060] As shown in FIG. 8, the user worn glove includes a detector
configured to read/ascertain data indicative of the club used, and
transmit or render available, this data to a remote device such as
unit 306 or 316, or any other data unit as desired. The advantage
of this embodiment is that an active sensor or passive sensor can
be placed on or within the club, which may be cheaper. This
embodiment may not include an accelerometer, and may simply just
count shots on each hole and the total for the round, or may also
provide useful data during actual game play for consideration by
the golfer prior to the next shot, or set of shots.
[0061] FIG. 9 is a flow diagram of the processing steps that may
taken by the display/scoring unit 306 and 316 in conjunction with a
single swing detector of type 200, during a normal round of golf.
As shown at step 902 the system is initialized, set to the desired
mode, and started.
[0062] When the scoring unit resets during power-up, or is reset by
a player, it remains in a standby state awaiting a user's input.
Internal flags are initialized and sensor inputs are disabled until
a player initiates the start of a game. The player may select a
game, or to download stored information to a PDA, or other
additional functionality. The display is updated at 904 and the
player is queried as to the type of mode desired. During
recreational games 906, the user is allowed to modify the stoke
count determined by the automatic scoring system 908. Other rounds,
such as those during a high school competition, could be set to
lock out any user input that affects the score 910. Additionally,
this data may be broadcast in real time, or delayed, to a central
location, such as a server, to obtain and display multiple player
data for analysis or review.
[0063] In one embodiment unit 306 or 316 will now wait for input
from a swing device 200. Upon receiving input from the device, the
state flow for the display/scoring by-passes step 912 and continues
to 922. When sensor device 200 detects motion at step 912, the
processor evaluates and performs data storage and calculations at
step 914. When a valid profile that affects unit 306 or 316 is
detected this information is transmitted to it. If the transmitted
information and the data within unit 306 or 316 determine that a
shot was taken at step 918, the shot count is incremented at
920.
[0064] Step 922 looks to see if a user input has occurred. The
actions that may result from an input are determined at step 924.
If the mode is recreational the score can be adjusted. In all cases
a user can flag an event for analysis, of the processed data, at a
later time. For example, if a player did not agree with the scoring
of a hole he could flag that hole. The inputs to, and the decisions
made by the swing counter, as well as the scoring unit could later
be reviewed.
[0065] The scoring display unit 306 and 316 as well as the swing
device 200 will continually be re-establishing a new current state
and determining how it may affect the next action. This occurs at
step 926. Finally, all raw data is stored during step 928 and the
process continues.
[0066] It is important to remember that the real time loop
presented in this flow diagram occurs repeatedly at microprocessor
speeds. The states shown on this diagram are simplified to
facilitate the explanation and teaching of this invention. It will
be recognized by one skilled in the art that methods and process
steps can be altered to occur in a different order or even
simultaneously, such as an internal counter routine updating status
variables or data calculations caused by timer interrupts to the
processor.
[0067] A GPS receiver coupled to, or integrated with, the above
swing detection system, such as the user worn display/scoring unit,
further enhances the present invention by providing ball location
and golf hole data correlated to the data obtained, such game play
and swing analysis.
[0068] The GPS receiver gathers information from multiple
satellites. With this information, the invention can accurately
determine the receiver's location during golf play. The GPS
receiver is designed to communicate with processing devices in
NMEA2.1 or similar protocol. Information about the receiver's
longitude, latitude, altitude, and time aid the invention in
providing the golfer the ultimate of real time and post play
analysis.
[0069] When the GPS unit is utilized in one preferred embodiment,
the cause-and-effect relationship of a golf shot, swing profile,
club, course, and other conditions can clearly be correlated,
tracked and presented in a graphical and easy to interpret display,
in real time in units 500 and 600, or stored for post game
analysis.
[0070] Graphical interfaces, and even animated interfaces, prove to
surpass the learning traditionally obtained within a control
facility, or environment, as well as greatly enhance the game
enjoyment.
[0071] For an example, using the display device 306 or 316, or a
remote PC/PDA with downloaded data there from, during
post-analysis, a golfer can pull up information about a round that
has been played. By zooming in, any particular hole may be
selected, or a screen button can be clicked. The player can choose
other options to learn about prior performance on a given course or
hole, and can add notes. Data can also be shared between users of
various automatic scoring systems equipped with a wireless
interface such as that shown in device 600, or even uploaded to
other sites, such as via the internet for further analysis, scoring
and processing.
[0072] Now looking at FIGS. 10A and 10B there is shown one display
that may be visually rendered by unit 306 or 316 during play.
Understanding that unit 306 may be an embodiment that only allows
for alpha-numeric type information, such as that displayed on a
micro-display, the information presented in FIG. 10A is
representative; however, the displayed unit may be such as a PDA.
In such a case the information is presented both in FIG. 10A and
FIG. 10B may be displayed. The visual display may include actual
game specific information, including shots taken, club used,
distance of each shot, hole information, course information, date,
and other statistics valuable to the golfer, in real time, during
the actual play of the game. This information can be used by the
golfer in determining one or more future shots on the same hole, or
a future hole. The user can scroll backwards and forward between
individual holes to consider play during the actual game. For
instance, while playing hole 10, the user can scroll back to the
display showing the play for hole 7 to ascertain the club and
distance parameter and use this information to determine which club
to play at a given location on hole 10. As a course is played more
frequently additional information you need in completing a more
detailed pictorial is obtained. By having this information a golfer
can more easily visualize what a given hole that was played like.
Hazards, doglegs, and other information may provide feedback and
why a particular club which chosen and why the distance with this
club may be significantly different than when this club was used on
a different hole.
[0073] FIG. 11 shows a display in another format, which renders
current game information, such as club performance/results during
the current game. For instance, the player can appreciate the
average distance of a shot as a function of the club. The results
can even be weighted or selectively removed/edited so one can
appreciate relevant information.
[0074] FIG. 12 shows a menu option so a golfer can, during game
play, see and consider how he/she played the hole on a previous
occasion. For instance, the player can select a desired course, the
date played, and the hole played, and hit enter. The stored
information for this entered data will then be displayed.
Advantageously, the golfer can appreciate data from previous actual
play on the same course or a different course, the same hole or a
different hole.
[0075] Now looking at FIGS. 13A, 13B, 13C, 14A, 14B, and 14C there
is shown the various club and body positions that occur and can be
detected and/or analyzed by detector 200 throughout the action of a
typical golf swing. This is accomplished by a combination of analog
and/or digital filtering, time profiling, and the effect of a shot
as observed by the location of the ball's final landing place. Once
again, referring to two distinctively different embodiments; that
of utilizing a GPS receiver, and that of accomplishing similar
informational data without the cost or benefit of a GPS receiver,
these various embodiments are summarized in tables 1 to 3. To some,
golf is a lifetime pursuit of perfection, while to others it is an
afternoon in the sun. Therefore, much consideration has been given
into how to teach multiple embodiments that reflect various market
and product decisions.
[0076] Depending on the embodiment, an ordinary skilled engineer
may incorporate one of several implementations presented here as
well as others enlightened by these teachings.
[0077] Let us first look at the various events detected by the
various embodiments disclosed: [0078] A simple ball strike; [0079]
a practice swing versus a whiff; [0080] a divot continuing into a
ball strike; [0081] a sand trap ball hit at the top.
[0082] While the simple ball hit may be basically shock detection,
a more sophisticated algorithm is employed to distinguish this from
the other above mentioned.
[0083] One may consider a swing profile analysis as a more complex
action than the aforementioned, and this is not the case when
implementing all of these features. A profile analysis of the swing
essentially deals with the acceleration or velocity, depending on
one's viewpoint of the swing. Also taken into account is the
relative position of the club in the x,y,z planes throughout the
profile.
[0084] Some of the desired information in swing analysis include
but is not limited to [0085] backswing velocity; [0086] swing arc;
[0087] club swing acceleration; [0088] club follow-through.
[0089] One should take note that the items mentioned here
essentially are referring to the detection on the club or near the
club, such as the golfer's wrist. Also, as clearly seen in FIGS. 13
and 14, the specifics of the golfer's body position are not clearly
addressed by the sensors located in one or both of those
regions.
[0090] An occasional recreational golfer may simply require the
convenience of an automatic scoring device. Improving golfers are
likely to be interested in correcting and consistently reproducing
a correct swing profile.
[0091] Table 1 is a tabular summary of various profiles that are
analyzed during a round of golf. These profiles are used to
determine/correlate a relationship between the golfer, elapsed
time, and input from the various sensors. With this information,
according to one embodiment explained later on, the invention may
simply keep automatic score of a golf round. When other sensors are
utilized, the invention allows one to track, show or render the
ability/actual play, advantageously providing more meaningful,
detailed, real-time information about one's performance.
[0092] Table 2 shows various profiles described, such as backswing
or RFID read. The profile used will be dependent on the embodiment
being implemented. Depending on the implementation, as shown in
Table 2, there is another way of looking at how to determine that a
golf shot was taken.
[0093] Table 3 complements Table 2 in that it provides a brief
description of the methods that are used with the various device
combinations to achieve these profiles.
[0094] Again referring to FIGS. 13A, 13B, and 13C one can observe
the various positions throughout a typical golf backswing. Shown in
these figures is a typical golfer 302 performing a swing using
driver 218. FIG. 13A shows a unit 200 configured to be worn on a
hat or hatband with the detector located on the forehead.
Additional sensors of this type may be worn in various other player
locations such as on a belt to detect hip and body shifting
throughout the swing. Sensors of this type may be attached in a
multitude of means, such as but not limited to clip attachments,
band attachment, and clothing with sensor integration.
[0095] Shown in FIG. 13 is a slight movement of golf club 218 at or
near golf ball 1308, shown at location 1310. In table 3 this is a
method described as club swing: aim alignment. The data is
collected from swing detectors 200 located on or in golf club 218,
and is coordinated with body worn detectors at locations 1304,
1305, and/or all the locations on which the golfer chooses to place
them. This data may be used to analyze both the effects of the club
swing profiles summarized in table 1 such as of club swing: aim
alignment 1310, club swing: backswing 1306; as well as those
effects introduced by the body movements themselves. Combined with
time and analysis, the golfer is provided with information vital to
identify the golfer's individual play characteristics and therefore
rapidly aid in the improvement of his/her play. Examples of such
information are backswing velocity, the lifting of one's head just
prior to the shot, the body positional alignment in its
relationship towards the flag and hole on the golf green.
[0096] In FIG. 13A the x,y,z positional coordinates shown at 1302
reflect those of the golfer's head throughout his swing, depicted
in all FIGS. 13A through 14C. Of particular importance is the
timing when a head position changes from viewing the golf ball at
location 1310 to watching its flight at the time of the swing
completion 1416 in FIG. 14C.
[0097] In FIGS. 13A to 13C, the total backswing path is represented
in stages shown starting as 1306, continuing through 1312, and
reaching its peak at 1320. The club angle change with respect to
the vertical is shown as 1314, while the body potion shift is shown
as 1316, and a final change in shoulder angle with respect to the
horizontal ground plane at 1318.
[0098] As shown in FIG. 13 the effects on the flight of golf ball
1308 from the club swing profile are primarily sensed and analyzed
from club mounted detector 200s during the path as shown by 1306,
1312, and 1320. The body's influences are shown here as 1302, 1316,
1318. Without the benefit of time analysis and the benefit of the
landing position of the ball, the instructional aid is diminished,
while for a casual golfer this information may still be
adequate.
[0099] FIGS. 14A to 14C show the forward swing continuation. Here
distinct locations of the swing are called out such as the
combination of 1402, followed by 1406; continuing 1410 to 1412, and
1414 to the completion of the swing at 1416. These points, as well
as those that similarly occur within the swing paths shown in FIG.
13, indicate approximations of data collection times based on
device 200 sensor input that is used during time/event profiling
when a club is swung.
[0100] According to the various embodiments of this invention, this
data can be obtained by the sensors 200 in real time.
[0101] Data Protocol Transfers
[0102] Dependant on the embodiment, either the display gaming
device or the swing analyzer can initiate the start of data
collection by the swing analyzer. The display gaming device may
send a start request to the swing analyzer, and the swing analyzer
then begins collecting data for analysis against desired profiles.
When the swing analyzer determines that a profile has occurred, it
transmits data back to the game display device.
[0103] Swing analyzer data transfer is both time and event tagged.
Data logging is maintained in an efficient manner, so for example,
if the golfer has taken practice swings but no ball hit was
detected that data could be marked for over-write. In the swing
analyzer, the RAM memory used to collect raw data is treated as a
stack, wherein when the last memory location allocated for data
storage is reached, the pointer is reset to the first location. If
a protection flag is set it proceeds to the head of the next set of
data.
[0104] Data transfer to the display unit may be either just
specifically requested information, or a complete transfer of all
raw data. Each time data is transferred via RF, power is consumed
therefore transfers are kept minimal
[0105] In one embodiment, what is transferred is only the pertinent
information. For instance, a ball hit has occurred in a mode
selected to only keep score. In another embodiment, such as where
analysis is performed, the pertinent sensor data is transferred
with the time tag and the event tag. The analysis of this
information is then correlated to one of the profiles discussed in
table 1 to 3.
[0106] At times a request for all raw data may be made for later
analysis. In such a case all of the time and event tags along with
their sensor values are transferred. Collecting this amount of raw
data requires an implementation using sufficient memory to allow
for 18 or more holes.
[0107] One protocol transfer sequence may look like this:
[0108] Here, time is expressed in milliseconds while accelerometer
x,y,z axis angle and acceleration are expressed as voltages.

[0109] Monolithic IC Accelerometers, such as an Analog Devices ATXL
330, can work in both static and dynamic acceleration modes. A
static acceleration of gravity is used in tilt sensing
applications. A dynamic acceleration is a result of motion, shock,
or vibration. Accelerometers of these type may prove advantages in
one preferred embodiment. As seen in FIG. 4, sensor input may be
applied directly to a processor I/O, may be conditioned and then
applied, or may be used as two inputs proving isolation to allow
for different filtering to take place out of the same
accelerometer.
[0110] Additionally, accelerometers are chosen as one to three axis
allowing for different levels of maximum g's. A user selects the
bandwidth of an accelerometer using external capacitors on each X,
Y, or Z. axis. Depending on the model of accelerometer chosen each
axis may differ in available bandwidth. For example, on a ATXL 330
device, the X and Y axis allow a range of 0.5 Hz to 1600 Hz, while
the Z axis is limited to 0.5 Hz to 550 Hz. Conforming to:
F.sub.-3db=1/(2 pi(32k).times.C.sub.(x,y,z)
[0111] Additionally advantages for this device is its low power
consumption and its ability to run from a single supply ranging
from 1.8 V. to 3.6 V. to accomplish this the signal outputs are
ratio metric. One must however be aware that while the output
sensitivity varies proportionally to the supply voltage the output
noise is absolute in volts. Or stated another way as the supply
voltage increases the noise density decreases: rms Noise=Noise
Density.times.(BW.times.1.6.)
[0112] While the low power consumption of these devices makes them
ideal for this application, one must be sure to take into account
these noise considerations due to the extremely low mV levels being
dealt with during calculations.
[0113] Referring to FIG. 15A ones observes the block 1504
figuratively showing a power interface between block 1502, which
may be a swing detector 200 or 400, and block 1506, which may be
unit 500 or 600 as previously described. This power interface 1504
may be implemented by various means depending on the embodiment.
Power may be provided by either direct physical contact as
illustrated by FIG. 15B, or by proximal location as shown in FIGS.
15C, 15D, and 15E.
[0114] In one embodiment power is transferred from swing detector
200 or 400 by direct contact as shown in FIG. 15B. Here positive
voltage and return conduction paths are shown at 1508 and 1510,
respectively. In this embodiment these conduction paths may be
implemented in the golf glove 804 and configured to transfer power
to a club grip 1610 when brought into contact therewith. In this
embodiment, paths 1508 and 1510 could directly relate to the
mappings as shown at 1802 and 1812 shown in FIG. 18, which will be
described in more detail shortly.
[0115] Power may also be transferred from swing detector 200 or 400
to unit 500 or 600 without direct physical contact such as using
inductive coupling as shown in FIG. 15C, capacitive coupling shown
in FIG. 15D, or power derived from an RFID field shown in FIG.
15E.
[0116] Referring now to FIGS. 16A and 16B there is depicted a
golfer's hand 1604 and the proper way of gripping a golf club 1610.
In FIG. 16A the golf club (grip) 1610 is shown laid on top of
golfer's palm. Of specific interest here are the palm areas
indicated as 1608 and 1616 in relation to the golf club grip
portion 1608.
[0117] In FIG. 16A, the club grip 1610 contacts the hand at various
locations in the region indicated at 1614. In FIG. 16B, the hand is
shown closed about the club grip 1610 and providing a positive
physical contact between fingers 1612, the area of the hand
indicated at 1602 and 1616, and the club grip 1610.
[0118] FIG. 16B shows in a similar manner positive physical contact
between the thumb 1606, the grip at 1610, and also the area of the
hand palm hand indicated by 1604 and grip 1610 in the region of
1616.
[0119] FIG. 17 shows a perspective view of the hand 1604 configured
to grasp club grip 1610, with the mapping of specific regions on
the hand 1604 and fingers 1612 to corresponding electrically
conductive contact points on grip 1610. A similar relationship is
shown in FIG. 18. Here, however, golf club grip 1610 is rotated
slightly to expose hidden electrical contact points, and also
highlight how a contact point on grip 1610 may vary in shape to
better meet with the desired areas of contact and the direction the
fingers take when gripping the club.
[0120] To avoid confusion it is understood that even though FIGS.
16A and 16B show the mapping between a golfer's hand 1604 and club
grip 1610, electrical conductivity as taught herein is between the
golf glove and the golf grip as shown in FIGS. 17, 18, 19, and 20
and also shown in FIGS. 3, 8, and 19, worn by the golfer.
Additionally, for left-handed golfers the hand and grip may be
reversed as appropriate.
[0121] Referring again to FIG. 17 one can see a direct
correspondence between specific contact points on club grip 1610
and the fingertips of the golfer's fingers 1612, such as shown at
1702, 1704, 1706, 1710, and 1708; numbered from the pinky to the
thumb, respectively. Also in this Figure is the point on the palm,
noted as 1712, that does not show a contact point on the club
grip.
[0122] Now referring to FIG. 18 once again, a direct correspondence
between specific contact points on the club grip in the golfer's
hand is shown. Here, however, the mapping indicated as 1802, 1804,
1806, respectively from the pinky to the index finger, shows the
correspondence between the hand at the base of each finger in the
region indicated in FIG. 16A as opposed to the finger tip mapping
shown in FIG. 17.
[0123] The distinction of the contact point mappings specifically
noted in FIGS. 17 and 18, between the golfer's glove and those on
the golf club grip, will be further appreciated in a discussion of
FIGS. 19 and 20, as well as the discussions on preferred
embodiments.
[0124] FIG. 19 depicts the golf glove of FIG. 17 and FIG. 18 shown
open, palm facing up. The electrical contact points of the physical
zones on the glove are configured to transfer power and/or data
information through physical proximity or physical contact with the
club grip as indicated at 1902. For instance, electrically
conductive portions 1902 may be situated proximate the palm of the
glove, the fingers proximate the palm, on the finger tips, or the
thumb tip as desired for the selected embodiment. Some of these
portions may also provide redundant paths for power or a circuit to
make sure a suitable electrical path is established when used.
These electrically conductive portions may be electrically coupled
to a processing unit, such as a processing unit (not shown) that
can be attached to the top of the glove or proximate a wrist
portion of the glove, or even wirelessly relayed to remote
processing unit, such as located at a golf cart.
[0125] FIG. 20 shows another representation of the golf glove with
alternate arrangements of the physical electrical contacts 2002
used to enable various embodiments In this embodiment, a plurality
of conductive contacts are arranged in zones, such as one zone of
contacts for each finger of the glove. The palm area of the hand
indicated at 1616 in FIG. 16 is configured to be proximate and
align with the linearly arranged electrical contact portion of the
glove when worn, generally shown at 2022. This set of electrical
contacts may be used by a controller coupled thereto (not shown) to
help determine that the club grip is properly oriented in the glove
when gripped. For instance, if contact with 3 or more of the
contacts of portion 2022 are made with grip contact portion 2202
shown in FIG. 22A then it is established that the golfer is
correctly holding the club during a ball strike.
[0126] It is understood that various arrangements of contacts may
be configured for the purpose of detecting proper and repeatable
hand grip positioning, and/or to insure contact and isolation
between other signal interface paths. FIG. 22B shows how the grip
may have a plurality of electrical contact arranged in zones
similar to some embodiments of the glove. Moreover, the electrical
contact points of the glove and/or the club grip may be non-planer,
and raised/protruding to further enhance establishing a reliable
electrically conductive connection when interfaced in use.
[0127] FIG. 21 depicts the golf club grip 1610 removed from a club,
longitudinally split and laid flat. Physical zones of the
electrical contacts on the club grip are configured to transfer
information and/or power through physical proximity to, or in
physical contact with, glove 1902. Here, it is clearly seen that
physical contact between an elongated vertical conductive contact
2102 is configured to align with the thumb contact 1902 when
properly gripping the grip. Likewise, a laterally extending contact
2104 is configured to align with the contact(s) of the index finger
sleeve of the glove. A laterally extending contact 2106 is
configured to align with the contact(s) 1902 of middle finger
sleeve of the glove, a laterally extending conductive contact 2106
for the contact(s) of the middle finger sleeve, a laterally
extending conductive contact 2108 for the contact(s) of the ring
finger sleeve, and a laterally extending contact 2110 for the pinky
finger contact(s). A palm contact 2112 is configured to align with
the palm pad 1902 of the glove.
[0128] Many materials normally do not conduct power or electrical
signals, such as a leather golf glove. According to one aspect of
the present invention, the golf glove's electrically conductive
portions 1902 may be implemented using stitching or embroidering
with electrically conductive thread, using electrically conductive
cloth, or adhering to the glove an electrically conductive patch.
Depending on the method chosen, resistance to electrical current
conducting there through varies. Therefore, the size of the glove
contacts 1902 is established to provide for suitable power
transfer.
[0129] FIGS. 22A and 22B show alternate representations of club
grips used in various embodiments of this invention. Electrical
contact pads 2202 each have a size and shape configured to provide
for electrical contact with one or more of the glove contacts 1902.
For instance, one of the laterally extending contact pads 2202 may
have a wider width such that one or more of the contacts 1902 may
electrically couple thereto. The number and size of the contact
pads 2202 are chosen depending on how many electrical data signals
may be desired, the amount of power to be delivered, the
reliability of the contacts, and the tolerance established to
ensure contact when the golfer's hand is shifted or oriented.
[0130] FIG. 23 shows a flexible circuit at 2302 that may be
embedded into, onto, or under the club grip. This circuit 2302 is
configured to interconnect with the various electrical contacts
shown in FIG. 21, FIG. 22A and FIG. 22B, and facilitate the
transfer of power and/or data signals between a corresponding golf
glove contacts and sensors on this circuit, within the golf club,
or sensors mounted on the club;
First Embodiment
[0131] Accordingly to a first embodiment, a swing detection device,
such as an accelerometer and processor may be coupled to each golf
club in a set of clubs. The user wears a game module configured to
communicate and process data from the swing detector during an
actual golf shot. A game module includes software, as well as a GPS
unit, whereby the accelerometer data as well as the club used can
be stored as a function of the golfer location provided by the GPS
unit, including hole information and golf course information. The
accelerometer can detect the shock of a ball strike, wherein the
computer module is configured to use this data to distinguish an
actual ball hit from a divot. Automatic scoring can be provided
along with GPS location coordinates and the golf club used. The
computer module may include a micro display.
Second Embodiment
[0132] Accordingly to a second embodiment, a swing detection
device, such as an accelerometer and processor may be incorporated
into a glove or as a wrist device. Each golf club is uniquely
identified utilizing a device such as an RFID tag that may be
passive or active as desired. In this embodiment the game module
would excite the RF tag while in close proximity to it to determine
the club used. Upon the event in which a player may switch clubs
the processing of data would allow for correctly identifying which
club was actually used last when the ball was struck. A game module
includes software, as well as a GPS unit, whereby the accelerometer
data as well as the club used can be stored as a function of the
golfer location provided by the GPS unit, including hole
information and golf course information. The accelerometer can
detect the shock of a ball strike, wherein the computer module is
configured to use this data to distinguish an actual ball hit from
a divot. Automatic scoring can be provided along with GPS location
coordinates and the golf club used. The computer module may include
a micro display.
Third Embodiment
[0133] Accordingly to a third embodiment, a swing detection device,
such as an accelerometer and processor unit may be coupled to each
golf club in a set of clubs. The user wears a communication module
configured to communicate and process data from the swing detector
during an actual golf shot. A separate module includes software, as
well as a GPS unit. This module may be a unit such as a properly
configured GPS unit located in a golf cart. Additionally this unit
may be a simple PDF type device or cell phone wherein simplified
performance data can be collected and stored for real time or post
analysis.
Four Embodiment
[0134] Accordingly to a fourth embodiment, a simplified shock
detection device along with and modified RFID sensor may be
utilized. In this embodiment a game module with query the sensor.
The capability would be such that a stroke would be counted for a
sufficient level of shock that results from a club striking a golf
ball. The game module would have the capability to determine that a
shot was performed, recorded the golf club used, and reset the
shock detection device.
Fifth Embodiment
[0135] Accordingly to a fifth embodiment, the user wears a swing
detection device configured to communicate and process data from
the swing detector during a shot. The data obtained from this
device provides additional analysis information when coupled to an
embodiment one, two, or three.
Sixth Embodiment
[0136] According to a sixth embodiment, a user wears a golfing
glove configured to communicate with a sensor, such as a
microphone, contained within or on a golf club. The received
signals from the sensor may be used to provide information during a
club swing that a golf ball was struck, or determine that the event
occurred. Upon analysis, determination can be made to increment the
total shots taken during a golf game.
Seventh Embodiment
[0137] According to a seventh embodiment, a user wears a golfing
glove that is configured to communicate by physical proximity with
a sensor, such as an RFID, contained within or on a golf club and
providing a unique identification the club.
Eight Embodiment
