  • Patent number: 7153217
    Abstract: A golf swing training apparatus is intended for use in learning the proper technique of swinging a golf club to hit a golf ball and accelerate the golf ball along an intended path. The training apparatus includes a planar reflective panel, such as a mirror for visually identifying a users swing path. The training apparatus also includes a rigid panel for strengthening and supporting the reflective panel.

  • Patent number: 7115155
    Abstract: An air filtration and aromatizer apparatus which includes a housing, a motor in the housing with a fan for drawing air through an inlet toward an outlet through a pollution-collecting chamber, and an elongated hollow tubular perforated member having an upper end connected to the motor output shaft and a lower end disposed in a bath of water. The hollow tubular member is formed in such a manner that as it is rotated by the motor, it draws water from the container under the influence of centrifugal force, and then forces the water through the perforations to form a mist or rain-like atmosphere in the path of motion of the air passing from the housing inlet toward the housing outlet.

  • Patent number: 7108610
    Abstract: The present invention provides for a swing training device for golfers which allows a golfer to receive immediate visual feedback as to his stance, form, and technique. The training device includes a break-resistant mirror and long support legs mounted behind the reflective surface. These legs not only support the mirror in an upright position, but act as shock absorbers so that the golfer can repeatedly hit practice balls or throw a weighted training ball into the mirror. The legs deflect and then spring back, thereby reorienting the mirror back to its original position and allowing the golfer to remain in substantially the same location while training.
