  • Direction and distance correcting golf putter
    Patent number: 7674186
    Abstract: A golf putter has a putter head with an actively compliant beam which is parallel to the face of the putter. The beam connects to a shaft along its length and is separated from the head except for its ends. The force of impact between the face of the putter and the ball on the putter face sweet spot causes a stress to develop in the beam, resulting in a deflection in the beam proportional to the force of the impact, while maintaining the putter face orientation with respect to the putting line. Impacts which miss the sweet spot will cause the putter face to skew to an angle with respect to the putting line, also introducing a proportional flexure of the beam, depending on the distance between the sweet spot and the point of impact.

  • Golf putter with green-reading features
    Patent number: 6358162
    Abstract: A golf putter provides a horizontal reference line when the putter is freely suspended by its shaft. A longitudinal axis of the shaft passes through a center of gravity of the putting head so that the shaft, when suspended, extends vertically. The putting head forms a line which extends perpendicularly to the shaft, and thus forms a reference line which extends horizontally when the putter is suspended. The horizontal reference line can be compared to the direction of a portion of a golf green to aid in reading a slope of the green. During a putting stroke the putting head is better balanced and less susceptible to turning motions.
