Definitions

  • the present invention is directed to providing a system of golfing aids that can be used by a golfer on the golf course to improve his shots.
  • the system includes Location Information Transmitters (LIT) at predetermined locations within a golf course and a Mobile Electronic Transmitter/Receiver (METAR) carried in association with a golfer on a golf cart or golf bag.
  • LIT Location Information Transmitters
  • METAR Mobile Electronic Transmitter/Receiver
  • a METAR periodically transmits a METAR code over a restricted transmission range.
  • the LIT In response to the METAR being proximate to a LIT, the LIT receives the METAR code. After receiving the METAR code, the LIT transmits a play monitoring signal including its LIT code and the received METAR code to a Tracking Center located in a clubhouse. Golf course personnel in the clubhouse can monitor a display terminal of the Tracking Center and determine play of golfers, use of golf carts and use of golf holes.
  • the Tracking Center is notified and the golfer is asked to increase the rate of play or leave the golf course. Additionally, in response to the METAR receiving a signal from an LIT associated with a particular hole, the METAR can count down the time allotted to play that hole, and notify the golfer if that time is exceeded.
  • the above described system is directed to monitoring the throughput of golfers through a golf course by personnel in the golf club house. Since remote visual monitoring is provided and there is communication between club house and golfer, it can presumably be put to a secondary use to provide tips and instruction as well.
  • a drawback of the system is that it uses Location Information Transmitters (LIT) at predetermined locations within the golf course. These make the system golf course specific and do not allow the golfer to obtain instruction or feed back on any golf course, anywhere in the world, or even on an impromptu course, or whilst practicing in the office.
  • LIT Location Information Transmitters
  • United States Patent Number US 5,372,365 to McTeigue et al. titled “Methods and apparatus for sports training” describes a sports training device, especially useful to the golfer, that utilizes pressure sensors placed under the user's feet and between his hands and the golf club.
  • the patent describes a method and apparatus for training a user to move in a desired movement pattern, especially for training a golfer to swing a golf club.
  • One or more sensors are placed adjacent to the user, for example pressure sensors under the user's feet and/or between the user's hands and a golf club. The sensors generate signals corresponding to the user's movement.
  • a comparator and signal generator are used to compare a function of the user signals and a reference value, and to generate training signals which are communicated to the user, e.g. by radio frequency signals received by a headset worn by the user.
  • the user senses, during the actual movement, training signals which represent a relationship between the actual movement pattern and a desired movement pattern.
  • the comparator determines whether a function of the user signals is above or below a preselected and adjustable reference value, and the training signals undergo a distinct change when the function of the user signals crosses the reference value.
  • the system thus provides feedback to the golfer in real time regarding his swing. However, no permanent record is made for later analysis. Although the movement of the hands and feet is important, the movement of the head has particular importance, and this issue is not addressed.
  • United States Patent Number US 5,609,534 informational/training video system to Gebhardt et al. relates to video based training for e.g. sports or other activity and uses a video recording unit and measuring device at an activity site, such as a golf tee, with tape being cued for recording specific information during user play.
  • the system includes a video recording assembly and a measuring device located at a user activity site such as a tee box of a golf driving range.
  • a video tape including activity specific information on a first, pre-recorded portion thereof, is provided to the user for use in the video recording assembly at the user activity site.
  • the video tape is cued for recording user specific information on a second portion of the video tape during a practice session.
  • the sensor determines corresponding parameter information, such as estimated golf ball carry distance, for display on video tape.
  • the video tape and video recording assembly cooperate to provide a mechanism for preventing or discouraging use of unauthorized tapes and to ensure proper usage of the system.
  • This system appears to be permanently located at a specific location of the golf course. It cannot be used anywhere. Furthermore, the user has to put his video tape into the system at each location. It only enables post play analysis and doesn't address the issue of improving the game in real time.
  • United States Patent Number US 6,261,102 to Dugan et al. titled “Method and apparatus for teaching proper swing tempo” describes a speed measuring device for measuring the speed of a golf swing. It uses an accelerometer whose output goes through a voltage to frequency converter, amplifier and speaker so that the frequency of note indicates speed of swing.
  • a swing tempo training device is provided which may be used to teach proper swing tempo.
  • the disclosed swing tempo training device includes an accelerometer coupled to a voltage-to-frequency converter, and an output means coupled to the voltage-to-frequency converter.
  • the accelerometer measures the real-time acceleration of a swinging object and produces a first voltage signal with a voltage level related to the measured real-time acceleration.
  • the voltage-to-frequency converter then converters the first voltage signal into a second voltage signal with a frequency related to the first voltage level.
  • the output means then outputs the second voltage signal.
  • the output means includes a frequency modulator and an FM transmitter.
  • Dugan's technology gives a real time audible indication of the speed of the golf swing, but does not provide any indication of the accuracy thereof. It does not provide instruction on how to improve the swing.
  • United States Patent Number US 6,786,730 to Bleckley et al. titled "Ergonomic motion and athletic activity monitoring and training system and method" describes a system for teaching and learning a preferred ergonomic motion.
  • the system includes a video camera for capturing successive images of a person executing an ergonomic motion.
  • the system includes a threshold definition system that allows a user to define a spatial region of the video image through which motion should or should not interfere. If the spatial region is interfered, the system actuates an alarm, thereby providing feedback so the user may alter the technique of the next attempted motion.
  • the system is used in teaching a golfer to execute a preferred golf swing. The golfer adjusts the spatial region to define a space through which neither the golfer's body nor club should pass. If the spatial region is intruded upon, an alarm is actuated. For example, the golfer may define the region such that if the club moves off plane during a swing, a tee removal system causes the ball to disappear. In this manner, the golfer is only able to hit the ball when the club stays on plane.
  • the invention works with reverse logic as well, and may equally be applied to any number of ergonomic activities.
  • the technology described provides a photographic record for later analysis and an "alarm" indicating when a golf swing was wrong. It does not provide instruction prior to making the swing.
  • the system is not automatically activated and is not easily transported.
  • the data from the sensors may be fed into a digital processor to process the sensed data and derive a signal indicative of the wearer's head motion or position.
  • Some embodiments employ a programmable processor to adapt the head gear to a variety of applications.
  • the signal indicative of head motion or position may be fed into an indicator to provide the wearer with a recognizable feedback signal indicative of head motion or position.
  • United States Patent Number US 5,952,921 to Donnelly titled "Misplaced golf club reminder" describes a system for alerting a golfer when the golfer has moved too far away from his golf club.
  • One or more clubs are provided with transmitters which transmit on a specific frequency and may contain digital encoding.
  • a common receiver is used to detect the signal from one or a plurality of transmitters.
  • the receiver When the distance between the transmitter, attached to the golf club, and the receiver, carried with the golfer, is greater than a threshold distance, the receiver provides an alert to the golfer.
  • the present invention can also include an audible or visual signal associated with the club to assist the golfer in locating the club when he returns to retrieve the club.
  • United States Patent Number US 6,753,778 to Kruger et al., titled "Orientation / time sensing alarm device for golf club” describes an orientation / time sensing alarm device which includes an orientation sensor, a time sensor connecting to the orientation sensor, and an alarm connecting to the orientation sensor and the time sensor, forming a circuitry. The time sensor is activated by the orientation sensor when the orientation sensor senses the alarm device is above a predetermined orientational threshold.
  • the alarm is activated when the time sensor senses the duration of activation of the time sensor being above a predetermined timing threshold. Also provided is a self-reminding golf club having an orientation/time sensing alarm device connected to the grip of the golf club for reminding a golfer of a misplaced golf club. Though relating to golf clubs, the technology described in the above patents serves to prevent golf club being lost and does not relate to correct usage thereof.
  • the stance minder includes an elongated slotted base member or line corrector having a pointed end and an elongated longitudinal slot which is positioned on a golf course surface with the pointed end in the direction of a desired target area of the golf ball.
  • Attached to the base member is a perpendicular member forming a position reminder that is oriented perpendicular to the base member and extends laterally therefrom in an adjustable manner due to the provision of a longitudinal slot which intersects with the slot in the base member and a clamp bolt assembly secures the base member and perpendicular member in adjusted positions.
  • a pair of foot position indicators or correctors each including a concave side and being substantially alike in construction which extend laterally from the base member opposite to the perpendicular member for indicating the correct positioning of the feet of a golfer with the left foot position indicator of a right handed golfer being longitudinally adjustable on the base member by a clamp bolt extending through the slot in the base member with the perpendicular member oriented generally between the foot position indicators.
