Definitions

  • the flight path of the ball is the measure of success in any golf shot. That path is the direct result of a series of physical actions that are mastered by practice. Slowed video analysis is the best way to clearly see all the complex actions that take place during a golf swing. Such analysis does not improve the swing of the subject; it only helps determine what needs improvement through practice. Many devices have been invented to help golfers improve their play by helping them improve their practice. Most of these devices are impractical to use when actually practicing hitting golf balls. Inventions that require modification of the user's club, or that require complex, attachments to the club, are not practical for practicing the subject's natural golf swing, Practice aids that are intrusive to the golfer's routine or to other golfers in the vicinity are also impractical.
  • An optimal training aid would allow the golfer to use unmodified, regulation equipment at the normal place and in the normal manner, and would provide simple, real-time feedback to the golfer relative to his entire swing, from setup to impact with the ball.
  • Popular practice aids help the golfer work on one or two aspects of the swing. The entire swing, including setup, tempo and the club position at impact, together with the club head shape, speed, and path of approach, determine the results of the shot. An important part of any golf shot, the actual impact of the club on the ball, even during the softest short shots, is too quick for the human eye to see.
  • the training aid of this invention is a compact, portable, comprehensive golf practice aid, designed to be used by any golfer, using any club, at indoor or outdoor practice venues, with or without the aid of an instructor, to learn and improve most aspects of the golf swing.
  • the invention uses sensors to detect transmissions emitted from a stance/target reference bar, producing a plurality of narrow fast response break-beam type sensors to detect club position and motion.
  • the stance/target reference bar serves as a reference for the user to position his or her feet relative to the ball and target.
  • the device After detecting the start of a backswing, the device emits an adjustable sensory cue to assist the user in perfecting the tempo of the swing.
  • the training aid can produce a high intensity ultra short duration burst of ultraviolet (UV) energy, invisible to the naked eye, which is focused on the hitting area.
  • UV burst can be selectively triggered by any of the break-beams.
  • This UV pulse source is used in conjunction with certain materials located on the face and/or upper surface portions of the club head, and which fluoresce brightly under ultraviolet energy.
  • the UV pulse highlights and "freezes" an image of only the club head and ball, which is retained on the user's retina for only an instant, without lighting the surrounding area and without distracting nearby golfers.
  • FIGURE 1 is an isometric view of one embodiment of the invention in the right- handed configuration.
  • FIGURE 2 is a view of one embodiment of the invention from the right-handed user's perspective.
  • FIGURE 3 is an example of one embodiment of the control panel from the right- handed user's perspective.
  • FIGURE 4 is an example of one embodiment of the invention in which the stance/target reference arm is attached to the main body by a flexible means.
  • the training aid may comprise a main body (1) for housing or supporting components.
  • the main body comprises a top and opposing bottom, two opposing ends, and two opposing sides.
  • the main body may be comprised of any suitable durable, rigid material or combination of materials which are readily apparent to any person having skill in the art. Examples of appropriate materials include, but are not limited to woods, metals, plastics, fiberglass, resins, and the like.
  • the main body may have one or more optional components (not shown) attached to the bottom for stabilizing the training aid on uneven surfaces.
  • Stabilizing components may include, for example, pegs, wheels, castors, feet or legs which may further optionally retract, extend, or adjust independently to multiple lengths.
  • the main body may be formed into a permanent or semi-permanent structure such as a concrete enclosure or wall.
  • the training aid comprises a moveable stance/target reference arm (2) comprised of any suitable durable material or combination of materials which are readily apparent to any person having skill in the art. Suitable materials include, but are not limited to metals, plastics, fiberglass, resins, and the like.
  • the stance/target reference arm (2) is capable of forming delineation between the user and the main body (1), as illustrated in Figures 1 and 4, and is aligned with the target area direction (22). It provides a reference for observing and adjusting the user stance position (30) and the user stance angle (31).
  • the stance/target reference arm (2) may be attached to the main body (1) by any suitable means capable of holding it in the design location relative to the main body (1), which would be readily apparent to any person having skill in the art.
  • it is attached by employing, for example, a rotating cylinder and sleeve mechanism such that the arm may freely rotate from one side of the main body to the other, in order to accommodate both left- and right-handed hitters.
  • a ball joint mechanism may be used.
  • it may be attached by employing, for example, an electrical cord or cable, as shown in Figure 4.
  • the stance/target reference arm (2) is detachable, for example, by using plug-in type connectors.
  • Embodiments in which the arm is detachable or connected by non rigid means, such as a flexible cable, may include a visual (laser line (46) shown in Figure 4) or audio means of indicating the correct position of the stance/target reference arm relative to the main body.
  • the stance/target reference arm could have no physical connection to the main body and would still serve its intended function, if it contained, for example, a power source for the sensor emitters and was correctly positioned relative to the sensor receivers which make up each source/sensor signal pair.
  • the stance/target reference arm (2) may telescope to a shorter configuration for storage and/or may optionally rest in one or more optional holders (16) attached to the main body (1) for storage when not in use.
  • the stance/target reference arm may be secured in the one or more holders (16) in order to operate additionally as a carrying handle for portable models.
  • the main body (1) is a permanent or large structure
  • the stance/target reference arm (2) may be folded into an optional storage recess located in the structure.
  • one or more optional carrying handles are connected to the main body (1), preferably at the top and /or at either or both ends.
  • the stance/target reference arm (2) comprises a plurality of signal sources (3, 4,
  • the signal source/sensor pairs may be formed by any means readily apparent to a person having ordinary skill in the art. Examples of signal source/sensor means include, but are not limited to lasers and infrared (IR) light emitting diodes (LED), paired with matching sensor elements or detectors. A single energy source could provide the energy emitted from multiple locations on the stance/target reference arm, for example, by means of light pipes or other optical means.
  • IR infrared
  • the sensors are positioned inside the main body (1), for example, and may be in alignment with signal sources (3, 4, 5) through sensor openings or windows of material (6,7,8) that freely pass the frequency of the signal sources to the sensors in the main body (1).
  • the case of the upper main body may be made from material that passes IR beam frequency, such as VIVAK ® thermoplastic, for example.
  • three such alignments of IR signal sources (3, 4, 5) (type QED 123 IR LED emitters) and sensors (type QSD 123 IR phototransistors) are employed, as depicted in Figures 1, 2 and 4, although different numbers and types of signal source/sensor pairs may be employed.
  • Each signal source/sensor pair functions to create a narrow line of sight, fast response IR break-beam (9, 10, 11).
  • the sensors can be photocells or photodiodes or other devices capable of sensing incident energy level changes, such as changes in position or velocity.
  • the output of these sensors are directed to circuitry designed to quickly respond when an object, such as a golf club shaft, interrupts the path of the energy from source to sensor.
  • the field of view of each sensor element is mechanically or optically limited to ensure that energy from only the matching emitter is measured, in a point to point manner, and the circuitry is designed to detect rapid changes in the level of incident energy, velocity or position.
  • three sensor openings (6, 7, 8) are employed on each side of the main body (1), as depicted in Figures 1 and 2 (only one side is visible in these views), to accommodate for the configurations of the stance/target reference arm (2) and associated IR signal sources (3, 4, 5) when in the right-handed position, as well as when in the left-handed position (15). It should be understood that alternative embodiments exist in which the stance/target reference arm (2) and main body (1) are configured such that the sensor openings (6, 7, 8) may be present only on one side of the main body (1).
  • the sensor openings (6, 7, 8) may be located on the top of the main body (1) incorporating use of a mirror (not shown) attached to the underside of a mirror hood (17) in order to direct the signal sources (3, 4, 5) to the sensors (not shown) in the main body (1).
  • Alternative configurations are readily apparent to any person having ordinary skill in the art and are merely design options.
  • An embodiment of Figure 4 is shown in the right hand configuration. It converts to left hand use by moving the internal LED UV source (not shown; described below) positioned inside the left side of the upper main body (1) to a position inside the cover on the right side of the upper main body by means of the tab (41).
  • the connecting cable (42) is then unplugged from the position shown and moved to a corresponding position on the left side, using the connector points (43) on that side.
  • the ball and hitting area would be as shown (44), relative to the main body and the new target direction is as shown (47).
  • the IR break-beams (9, 10, 11) may be characterized in their proximity to the ball location, for example, where a first beam (9) is nearest the ball, an additional beam (10) is a greater distance from the ball than is the first beam (9), and another beam (11) is the greatest distance from the ball.
  • These beams are "broken" sequentially as the club shaft or head passes through them, allowing the control circuitry to determine the direction and calculate the speed of the club.
  • This break beam type sensor arrangement provides an obvious advantage in that no hardware or other visible distraction need be located in the area where the ball rests on the hitting surface or tee.
  • the training aid of this invention can be used while hitting a real golf ball, off real grass, while taking real divots, with real clubs to which no mechanical devices have been attached.
  • Other sensor arrangements could be used so long as they detect the position of the club at more than one point during the swing. Some arrangements would require attachments to the club and would limit the modes in which the training aid could be used.
  • An example of an alternate system of sensors to detect club position is the sensor arrangement utilized is the P3ProSwingTM Golf Simulator and Swing Analyzer. It uses the Sports Swing Analysis System described in U.S. Patent No. 6,821,211, employing a plurality of photodetectors arranged in arrays within a support structure, signals from which report the passage of a reflector attached to the bottom of the golf club head.
  • This system is well suited for use in golf game simulators and swing analyzers in which the data related to the motion of the attached reflector is transmitted to a computer that performs calculations to produce a graphic or video representation of the swing and of the probable flight path of a ball struck with a club using that calculated swing.
  • a large number of individual time stamped sensor readings are required to accurately generate a full graphic simulation of an action as complex as a golf swing.
  • the training aid which is the subject of this invention requires as few as two such sensor readings in order to provide its primary benefits; the most important of which is the ability to actually see the club at a selected point in the swing, especially at impact.
  • This invention could be used without modification by the designer and software writer of a golf simulator or swing analyzer machine to quickly verify the accuracy of his hardware and software. He could compare the computer generated image at a chosen point of the swing to the real image of the actual club at the same point, then modify his hardware and software until the two images matched exactly.
  • the UV source portion of this invention by itself, modified to accept inputs from other devices such as the swing analyzer described above, could be used as an enhancement to such devices with a simple interface and some fluorescent material.
  • the signal source/sensor pairs may optionally be associated with one or more
  • LEDs or status lights (12, 13, 14) that may be set to illuminate or extinguish when the beam is broken, for example, by the movement of a golf club through the beam.
  • the status lights (12, 13, 14) may appear the same or different, such as in the use of multiple colors.
  • 2 and 4 status lights (12, 13, 14) are optionally situated above the sensor openings (6, 7, 8). It should be appreciated that other configurations serving the same function could easily be designed by any person having ordinary skill in the art.
  • the status LEDs are visible through unmask areas of the plastic cover (45).
  • the main body (1) comprises at least one variable, short duration (less than .001 second), high-intensity ultraviolet (UV) energy source (19).
  • UV energy sources are readily apparent to any person having ordinary skill in the art and include, but are not limited to an array of UV emitting LEDs, or a single or group of filtered flash tubes and the like. Because this invention is a new application, no UV sources are currently marketed that can ideally meet its requirements without modification.
  • the embodiments shown in Figures 1 and 2 utilize two quartz glass xenon filled photo flashtubes of the type used in studio photoflash equipment. Because UV is undesirable in normal photography, these products are often designed to lessen or eliminate the UV portion of their output, so only those without UV blocking features should be used.
  • Flashtubes of this type require high voltages, up to 900 VDC and higher from anode to cathode, and triggering voltages in the 4000-5000 volt range, depending on which of the many available models is chosen. They emit a large amount of light energy, a small fraction of which is in the ultraviolet range (400 nanometers and below).
  • a low bandpass filter designed to pass only frequencies below about 400 nm can be positioned in the path of the emitted energy, changing it from a blinding flash of bright light to a nearly invisible pulse of UV radiation.
  • These filters have very few real world applications and are not widely available for purchase in the size required for this application.
  • Embodiments in Figures 1 and 2 use 2 77mm UV Black 403 camera lens filters sold by Schneider Optics. They are normally used in UV photography but provide acceptable results in this application. While usable, the filtered flashtube method of generating UV is extremely inefficient, requiring a large high voltage power supply and large photoflash type capacitors.
  • the flashtubes used in embodiments shown in Figures 1 and 2 are commonly sold as model C4-5, mounted in custom reflectors.
  • UV LEDs operating in the 3 volt range available in many wavelengths. They are marketed for, among other purposes, curing and drying of UV sensitive material, and fluorescent excitation. Handheld UV lights allow the user to see inks, dyes, paints and naturally fluorescent material which cannot be seen under normal visible light. Kits are marketed to convert popular pocket flashlights into a UV source. They are widely used to check currency, inspect crime scenes, look for scorpions, study minerals, etc. While producing only low energy levels, they work well in subdued light conditions and provide long battery life.
  • a more preferred embodiment of this invention, shown in Figure 4, necessitated the development of an application specific UV source, having the advantages of both the high power flashtube and the small efficient LED, without the disadvantages of either.
  • the solution employs a plurality of the most powerful UV LEDs available and mates them with a microprocessor controlled electronic driver circuit which allows them to be energized for a short and variable duration (less that 0.0005 seconds) at a current level many times their rated value. The energy is directed to a designated area using lenses and reflectors. The efficiency of LED generated UV is such that the device can be operated for hours on a single power tool type 9.6 volt battery. Two types of UV LED flash heads have been designed and fitted to this embodiment.
  • the first uses a plurality of high flux 45OmW LED based illuminators, model OTLH0280-UV from Opto Technology, Inc., with a peak wavelength 375nm.
  • Each illuminator contains 50 dies arranged in a 5 XlO matrix. They are rated at 300mA static forward current which requires about 17 VDC, and produces insufficient energy for this application. However, when energized at over 70 VDC for 0.0001 seconds, and mounted behind collimating lenses, they produce the needed energy at the hitting area to energize the fluorescent material brightly.
  • a second successful flash head uses a plurality of model XR7090UV-L 1 -0001
  • UV LEDs from Cree Lighting, which come mounted in 1-watt packages, allowing them also to be operated at may times their rated current for very short durations. These devices can be destroyed in as little as 0.001 seconds if left on at the currents being used, but for this application, they need never be turned on for longer than 0.00015 seconds. Longer "exposures" would produce less than sharp visual images of a golf club at full speed. The commercial success of this invention will hopefully prompt the design of a new generation of UV LEDs specifically engineered to be used in this application.
  • LEDs designed for this application might have peak wave lengths matched to the optimal fluorescent response of the fluorescent materials most readily incorporated into the outer surfaces of golf club heads, baseball/softball bats, and other athletic equipment, so as to produce the most intense image in the eye of the user.
  • the UV energy source (19) is directed to the hitting area (20) via any suitable configuration.
  • an optional mirror (not shown) is attached to the underside of a movable mirror hood (17) and is positioned to reflect a vertically configured UV energy source (19) onto the hitting area (20).
  • the mirror hood (17) may be movable to a left-handed mirror hood position (18).
  • Suitable means include, but are not limited to use of light pipes, lenses, prisms, reflectors, or different positioning of the UV energy source (19).

  • All adjustable components, if present, should be situated for proper left- or right-handed configuration, for example, the stance/target reference arm (2) and mirror hood (17). If a hitting mat having a fixed tee position is employed, the training aid should be set up such that the ball/tee location (26) coincides with the fixed tee position on the mat.
  • an optional laser cross beam (27) may be configured to automatically initiate, for example, by blocking a designated break beam (9, 10, 11) for two or more seconds, or by momentarily blocking the beam nearest the tee position when teeing a new ball.
  • the user may select a desired sensory tempo cue, if more than one cue type is provided, and also adjust the cue type, if necessary. For example, where an audible cue is provided, the user may optionally adjust the cue to varying levels of sound. In the illustrated embodiment, adjustment may be performed with the tempo cue selector switch (28). In an embodiment shown in Figure 4, all choices of cue options are entered by breaking beams, for example, with a club in response to prompt shown on the LCD textual display (40). It should be appreciated that other sensory cues may be employed, for example, visual cues, such as light, or somatosensory cues, such as a puff of air. In one embodiment, the tempo cue may be configured such that the laser cross beam (27) temporarily illuminates as the cue.
  • the user may select a tempo speed with which to commence training.
  • the user should take a stance position (30) and stance angle (31) in alignment to the stance/target reference arm (2), as depicted in Figure 2, for example.
  • the start of the user's backswing across break beams (10, 11) activates a tempo cue after a slight delay, for example, an audible tone emitted from a tone generator (not shown).
  • the user may adjust the tempo speed such that the cue coincides with the hesitation during the transition from the user's backswing to downswing.
  • the user may use the desired tempo during practice in order to develop a uniform swing tempo.
  • An optional power indicator light (25) may be programmed to indicate that the unit is ready to produce full power UV energy and that all sensors are working properly.
  • the UV energy source (19) may be programmed to automatically energize briefly when the club passes through and breaks a particular break beam (9, 10, 11) during the downswing.
  • the selected beam may be designated, for example, by making a selection with an image mode selector (32), as depicted in Figure 3 or by responding to prompts on the textual display (40) shown in Figure 4 or by other means readily apparent to those having ordinary skill in the art.
  • each image location (33, 34, 35) provides unique information as to the user's swing and club position as the club approaches or impacts the ball, and may be selected to best reveal the flaw that the user is attempting to correct. Fine adjustment to the exact location of the image can easily be accomplished by slightly adjusting the location of the stance/target reference arm as shown in an embodiment of Figure 4. The point-to-point nature of the break beams make this possible. Such small changes could be used, for example, to adjust the image seen by the user from one in which the club is just starting to make contact with the ball to one in which the ball is seen crunched into a distorted shape on the club head face.
  • the brightness of the UV energy source may optionally be adjusted depending on the ambient light levels and other parameters, such as the user's preferences. As depicted in Figure 3, an optional brightness selector switch (36), may operate to adjust the amount of UV energy applied to the hitting area (20), and therefore affecting the resulting degree of brightness of the fluorescing image. An ambient light sensor could also be incorporated to automatically set the brightness level. The duration of the UV energy pulse may be automatically adjusted within pre-programmed limits to produce a sharp and clear visible image, dependant on the speed of the club during any individual swing.
  • the training aid may display club head speed by comparing subsequent swings to a user established standard.
  • a "set speed momentary toggle switch” (37) may be activated, after which the speed of the next swing is measured as the standard.
  • the training aid may then electronically record the time between the club crossing two break beams (9, 10) during a downswing. Future UV energy triggers can be delayed for one half of that recorded time resulting in a user established standard. Every swing thereafter that is the same speed as that used to create the standard results in an image at the same position between the break beams (9, 10) as depicted, for example, in Figure 2 as the speed measurement image location (38).
  • a "set speed momentary toggle switch” (37) is located on the control panel (21). Once the switch has been activated, the speed of the next swing is recorded for use as the standard. In one embodiment, after the switch has been activated, the power indicator light (25) may blink, thus alerting the user that the next swing speed will be recorded. As the user develops a desired improvement in swing speed, as indicated by changes in the "frozen" image relative to the speed measurement image location (38), the user may re-record the standard swing speed for further practice and improvement.
  • speed related image delay routines may be included.
  • the speed of each swing may be made to appear on the textual display in a manner chosen by the user from a list of choices displayed.
  • Speed measurement options are only limited by the number and accuracy of the sensors employed and the limits of the microprocessor installed.
  • One such modification is the addition of a mechanism to anticipate the likely point of impact when both the striking implement and object struck are moving, as in baseball batting practice.
  • the embodiment of Figure 4 could be easily modified by extending the height of the main body and changing the angle of the break-beams to make visible the impact of a bat with a ball placed on a batting tee if the bat were coated with a fluorescent material.
  • Another such adaptation would be placing an inertial sensor in or on the striking implement or object struck, to detect the instant of impact and trigger via radio frequency or other means the UV energy source.
  • a tracking system to direct the UV source to an anticipated area of impact, batters could see clear images of the instant of contact of a bat on a pitched ball in a batting cage.
  • the common element in each of these applications and adaptations is the use of a short duration high energy UV source used to make clearly visible to the human eye the position and orientation of a moving object or objects at a selectable point in time and space for the purpose of analysis in the practice or playing of a sport or game.

Abstract

L'aide d'entraînement de cette invention est une aide complète à la pratique du golf, conçue pour être utilisée par un golfeur quelconque, utilisant un club quelconque, en des lieux de pratique intérieurs ou extérieurs, avec ou sans l'aide d'un instructeur, pour apprendre et améliorer la plupart des aspects de l'élan de golf. L'invention comprend un bras de visée qui sert de référence pour apprendre et corriger une position du joueur par rapport à la balle et la cible. L'invention utilise une pluralité de capteurs de type faisceaux coupés pour détecter un mouvement de club. Le dispositif donne des signaux sensoriels pour aider l'utilisateur à ajuster et perfectionner son tempo d'élan. Le dispositif mesure également la vitesse de club entre des points fixés, et aide l'utilisateur à ajuster et perfectionner la vitesse d'élan en produisant une représentation visuelle des changements dans la vitesse d'un élan à un autre. Pendant l'élan, l'aide d'entraînement peut produire une rafale ultracourte de forte intensité d'énergie ultraviolette (UV) invisible à l'œil nu, qui est concentrée sur la zone de frappe. La rafale d'UV peut être déclenchée sélectivement par un quelconque des faisceaux coupés ou un autre type de capteur. Cette source d'impulsions UV est utilisée conjointement à une certaine matière à appliquer ou incorporer dans le club, et qui devient vivement fluorescente avec une énergie ultraviolette. L'impulsion UV souligne et 'fige' une image seulement de la tête de club et de la balle, qui est retenue sur la rétine de l'utilisateur pendant seulement un instant, sans éclairer la zone environnante et sans déranger des golfeurs avoisinants. Par cette utilisation du dispositif et du procédé, l'utilisateur peut voir la position et l'orientation de la tête de club en relation avec la balle en un point sélectionné pendant l'élan. Cette aide d'entraînement peut être adaptée pour une utilisation avec d'autres sports. L'élément commun dans toutes ces adaptations est l'utilisation d'une source UV de forte énergie de courte durée utilisée pour rendre visible à l'œil humain la position et l'orientation d'un ou plusieurs objets mobiles en un point sélectionnable dans le temps et l'espace dans un but d'analyse pendant l'entraînement ou l'exercice d'un sport ou d'un jeu.
