  • Patent number: 11285369
    Abstract: An apparatus and method for repetitively training a golf swing is disclosed. In some embodiments of the present apparatus, foot placement guides are provided to align a golfer's stance relative to a golf ball on a tee. Motion and other data capture create a swing profile for the golfer's swing, which is compared to the swing of a golf Pro, thus giving swing feedback to the golfer. The apparatus automatically resets the ball position after the swing, allowing the golfer to repeat the swing based on the received feedback while isolating other variables (such as inaccurate resetting of foot position).

  • Patent number: 10737159
    Abstract: A portable sports practice net includes a frame with a base to which removable vertical poles having top side bar supports are joined holds a net to create an opening, such as a goal opening. The top side bar supports have a unique shape and extend horizontally from the top of the vertical poles in a manner that reduces the weight placed on the net fabric hung between the vertical poles. The top side bar supports also create a depth of the goal pocket without need for additional vertical posts. Each vertical post creates a pivot point at its bottom end, such that each vertical post is urged apart from the other post to create tension or leverage between the opposite top side bar supports, thus creating a net opening with a more realistic goal shape and reducing sag at the top edge.

A ball isolation system within the golf ball delivery shaft is configured to temporarily trap the ball within the shaft. A gate is configured to control the routing of a golf ball released from the ball isolation system. A control system queries the RFID reader while a ball is trapped in the ball isolation system. If the RFID reader receives a signal that identifies the golf ball as an RFID golf ball, the ball separation control system routes the ball to an RFID ball collector, otherwise, the ball is routed to a secondary location. After the determination is made as to where the trapped golf ball is to be routed, the ball isolation system releases the ball.

    Abstract: A movable simulated golf green enables the practicing of approach shots on a golf driving range, or other location. The apparatus is constructed as part of a motorized vehicle so as to be driven about to various selected locations on the range. The green surface is made of a flexible sheet material laid over, but only connected to a structural under layer along its periphery. Thus an air layer pumped between the flexible sheet and the under layer causes the flexible layer to rise to a position slightly above the structural surface. The inner facing surfaces of these layers each have a metallic contact layer on them so that when they contact each other an electrical circuit may be closed. The electrical circuit provides a power source and several lamps for illuminating when a golf ball contacts the green surface and forces the metal layers into contact momentarily.

A U-shaped clamp device is disposed on the L-shaped block. The U-shaped clamp device has an inner periphery groove receiving a light-emitting device and a through hole receiving a bolt. A switch is disposed on the light-emitting device. A nut engages with the bolt. Each lateral plate has a clip end engaging with the respective lateral notch, and a positioning device disposed on the lateral plate.

  • Patent number: 5823885
    Abstract: A portable personal sporting net includes a tapered cylindrical or funnel-like tubular, pliable, porous net having an enlarged entrance aperture which is supported by a collapsible pole. In one embodiment, a suspended exit aperture is formed at the opposing end of the netting. A ball capture bag communicates with the exit aperture to catch balls hit into the netting. In an alternative embodiment, the opposing second end of the netting is closed against the ground surface. A pair of flaps are mounted on opposing sides of the entrance aperture and radially extend forward and outward therefrom. The flaps assist in directing stray balls into the funnel-like netting.

  • Patent number: 5806848
    Abstract: An apparatus for determining a speed of a projectile uses control logic and a single acoustic sensor connected to the control logic. The control logic includes a pulsing clock. The control logic starts the clock upon receiving a first signal from the acoustic sensor and stops the clock upon receiving a second signal from the acoustic sensor. The control logic converts pulses of the clock into a numeric value indicative of speed based upon a preprogrammed distance measurement setting. The numeric value can then be converted into miles per hour and displayed to the user.

  • Patent number: 5779241
    Abstract: A sensor for locating the position of and measuring the velocity of an impacting object. The sensor employs a net attached at each edge to sensor modules mounted on a frame. Each sensor module includes an output drum, a take up drum, a spring and a motor. The net is attached to the sensor modules by cords wound on a spring loaded output drum. The drum is coaxial with a motor that generates a voltage proportional to the angular velocity of the drum. The diode isolated motor partially dissipates the energy of impact to heat on the return stroke in response to the restorative force of the spring. An object impacting a net draws the cord from the output drum, generating a voltage from an attached motor. A maximum voltage or an integrated voltage generated by the motors determines the velocity of impact. Each particular net has an associated set of axes. A pair of motors, their position known relative to the frame, are placed along these axes attached to one or more strings by a cord.

  • Patent number: 5735751
    Abstract: A golf putting target which includes a housing with sloped top sides and which is smaller than a regulation golf cup hole. The housing contains pressure bars, a battery, a normally open circuit and a sound synthesizer. When a putted golf ball rolls over the target a pressure bar is depressed completing a normally open circuit which causes the sound synthesizer to emit an audible sound providing feedback to a golfer.

  • Patent number: 5562285
    Abstract: The system for determining the carry and/or lateral deviation and/or flight time of a driven golf ball uses a grid of geophones to sense the time of impact of a driven golf ball. The geophones are buried in the ground so that the impact is sensed via sound waves travelling through the ground. A computer receives a signal from each sensor indicating an impact and determines the time at which the impact was sensed by each sensor and screens out all but the six shortest times of impact. This information is then used to mathematically calculate the point of impact within a square of geophones corresponding to the recorded times. A plot of the flight path of the golf ball can be displayed on a display monitor based upon the carry and the flight time. The calculated flight time and carry are compared with a known standard to determine conformance with the standard.
