Abstract: A golf club head having a face section with a polymer surface can provide a more efficient impact between a golf ball and the golf club head. By utilizing a polymer surface with desired material properties of stress, strain and damping levels, the face section will incur higher strain and strain rate levels than the golf ball. These lower internal stresses within the golf ball yield a more efficient impact with a golf club head.

Abstract: A method for a predicting golfer's performance is disclosed herein. The method inputs the pre-impact swing properties of a golfer, a plurality of mass properties of a first golf club, and a plurality of mass properties of a first golf ball into a rigid body code. Ball launch parameters are generated from the rigid body. The ball launch parameters, a plurality of atmospheric conditions and lift and drag properties of the golf ball are inputted into a trajectory code. This trajectory code is used to predict the performance of a golf ball if struck by the golfer with the golf club under the atmospheric conditions. The method can then predict the performance of the golf ball if struck by the golfer with a different golf club. The method and system of the present invention predict the performance of the golf ball without the golfer actually striking the golf ball.

Abstract: In a multi-piece solid golf ball comprising a solid core, an inner cover layer and an outer cover layer, the solid core is molded from a rubber composition comprising a base rubber composed of (a) 20-100 wt % of a polybutadiene having a high cis-1,4 content, a minimal 1,2 vinyl content and a viscosity &eegr; of up to 600 mPa·s at 25° C. as a 5 wt % toluene solution, and satisfying a certain relationship between Mooney viscosity and polydispersity index in combination with (b) 0-80 wt % of another diene rubber, (c) an unsaturated carboxylic acid, (d) an organosulfur compound, (e) an inorganic filler, and (f) an organic peroxide; and the outer cover layer has a higher Shore D hardness than the inner cover layer. This combination of features gives the ball a good, soft feel upon impact and excellent flight performance.

Abstract: A golf muscle weight training apparatus for attachment to the shaft of a golf club or other sports implement includes a weight carrier having an elongated weight supporting portion, a weight, and a clamp mechanism. The clamp mechanism cooperates with the weight carrier to clamp the weight carrier to the shaft with the axis of the weight supporting portion extending substantially perpendicular to a plane extending through the axis of the shaft and being offset laterally with respect to the axis of the golf club. The weight supporting portion supports a weight mass, with the weight mass extending in overlying relation with the head of the golf club. In another embodiment, the axis of the weight mass extends perpendicular to the axis of the golf club shaft. One or more extension weights can be coupled to the weight carrier to increase the weight mass of the weight training apparatus.

Abstract: A lineman trainer includes a base on which are mounted three receiving brackets. Pads are mounted over these brackets. Each of the brackets is mounted on a mechanism that allows the brackets to move. An actuator mechanism may be manipulated by a coach or other operator to activate the brackets independently of one another. When the actuator is reciprocated in one direction or another, it releases one or the other of the side brackets so that a spring can pivot the brackets toward the lineman. When the actuator is rotated so that its handle travels downwardly, the central bracket is released and springs push it directly outwardly toward the lineman. When a lineman hits a released bracket, it is moved back to the locked position ready for another movement when actuated by the coach or other operator.

Abstract: A lacrosse head having an open frame with sidewalk that curve continuously from the base to the lip of the frame so as to define a curved scoop-like frame geometry when viewed in side elevation. The frame base has an angulated ball rest surface and a shoulder recessed therefrom at which a net is attached to the base. The lip that interconnects the frame sidewalls remote from the base has an outside surface angle that cooperates with the scoop-like geometry of the sidewalls to enhance control of ground balls. The overall scoop-like construction of the head frame provides improved feel during play, and enhanced ball control and pass/shot velocity. The recessed base shoulder, particularly when combined with the angulated ball-rest surface, protects the net attachment knots from abrasion, and also improves ball control during one-handed vertical cradling.
