  • Patent number: 10661144
    Abstract: A golf swing training aid includes a golf club having a shaft and a club head. The club head has a hollow compartment for capturing a golf ball and is defined by a top wall, an opposing bottom wall, and a real wall. The club head has an open front face that forms an entrance into the hollow compartment. The club head has a slot formed within the bottom wall and being open along the front face of the club head for receiving a golf tee as the club head contacts the golf ball. An internal movable part is provided within the hollow compartment and moves between a raised position which allows the golf ball to travel to a rear ball capture space within the hollow compartment and a lowered position which is configured for capturing the golf ball within rear ball capture space located between the rear wall and the internal movable part.

  • Publication number: 20120007364
    Abstract: This Generator utilizes waters motion rotating NdFeB rotorblades within aluminum trapezoidal bars to generate electricity. The generator includes a moving magnetic field, wherein magnetic neodymium-iron-boron's embedded in turbine blades uniformly, with alternating polarity, circumferentially distributed about central axis drive shaft. The generator includes rotational speed controlled by secondary internally sourced electricity created by additional coils forming an internal generator fixed to the driveshaft independent of the turbine blades. Stationary Aluminum bars are induced to electrical conducting by internal movement of the magnetic field on the center axis and through aluminum bars, whereby the magnetic field cuts across the electrical conducting means in a uniform direction when the magnetic field is rotated, inducing a unidirectional electric signal in the Aluminum conductor bars thus completing the field.
