| 20090137333 | Golf putter assembly - A golf putter assembly includes a putter including a head, a display unit disposed in the putter, and a detecting unit disposed in the putter and electrically coupled to the display unit. The detecting unit is operable to detect and record a stationary starting position of a golf ball. The detecting unit is further operable to detect, during a practice swing, an instantaneous speed of the head as the head moves past the starting position, and to calculate what would be an initial speed of the golf ball if the golf ball was actually hit by the head with reference to the instantaneous speed of the head detected thereby. The detecting unit further performs control such that the initial speed of the golf ball as calculated is displayed on the display unit. | 05-28-2009 |
| 20110081981 | SPEED DETECTOR AND SWING TOOL HAVING THE SAME - A speed detector includes: a pressure sensor including a pitot tube attached to a moving body in a state in which an air inlet hole is directed toward a direction of a movement of the moving body, a diaphragm having a pressure receiving surface displaced by pressure, and a pressure-sensitive section adapted to receive force caused by the displacement to detect the pressure, the pressure sensor being disposed to the moving body and detecting the pressure caused in the pitot tube; and an operation section adapted to detect a speed of the moving body based on the difference between the pressure at rest and the pressure in movement of the moving body, wherein the pressure sensor is disposed so that a normal line of the pressure receiving surface becomes perpendicular to the direction of the movement. | 04-07-2011 |

| 20110300963 | PRACTICE GOLF CLUB CAPABLE OF ADJUSTING HEAD SPEED - The present invention relates to a practice golf club capable of adjusting head speed having a head (H) attached to an end of a shaft(S) having a grip (G), from which an impact sound is generated through a swing operation, wherein the head (H) includes: a first body ( | 12-08-2011 |
| 20090105004 | INERTIALLY RESPONSIVE GOLF CLUB HEAD MOUNTED DEVICE FOR INSTRUCTING CORRECT CLUB FACE DIRECTION & SWING SPEED - A device for a golf club for instructing club face orientation for a selected swing speed including a body with a selected thickness and such that a substantially pointed forward end thereof intersects a midpoint of the club contact face and in a perpendicularly extending direction relative to a coplanar axis extending across the club contact face. An adhesive tacky material applied to an underside surface of the body engaging the body to a top surface of the club head. A processor communicates with an inertially sensitive cam shaped member rotatably mounted within a location of the body. A swing speed adjustment knob is in operative communication with the body and in contact with the inertially sensitive element via an adjustment spring. An audio-generating transistor and a plurality of LED elements cooperate with the processor for instructing a correct planar orientation of a contacting face of the club head relative to the golf ball. | 04-23-2009 |
| 20110244976 | Apparatus for Analyzing a Swing of a Sporting Equipment - An apparatus for sporting equipment includes a housing. An inlet orifice is disposed on a first side of the housing for enabling a volume of air to enter the housing in response to the housing being passed through the air generally about a plane defining a swing. An exhaust orifice disposed on a second side of the housing for enabling the volume of air to exit the housing to produce a sound indicative of a path of the housing about the plane. Means joins the housing to the sporting equipment. | 10-06-2011 |
