            <description><![CDATA[A composite sporting implement, such as a ball bat or bat barrel, is formed with layers of continuous structural fibers embedded in a binder material having a high melting point. Such a binder does not undergo a chemical conversion process during forming of the ball bat. The layers are shaped into a preform and placed in a mold. Heat and pressure are applied to bring the binder to its melting point and to cause the binder material to flow between adjacent layers. The mold is then cooled below the binder's melting point to solidify the composite structure. A composite sporting implement formed in this manner exhibits excellent shear strength, toughness, and damping qualities.]]></description>

            <description><![CDATA[When golf is being played, the golf swing of a person (60) is decisive for the quality of the stroke. In order to obtain as good a golf swing as possible with a high hitting reliability and with precision, it is necessary to rotate the club with the arms (70) in a positionally fixed fashion about an imaginary axis through the head (68) and upper body (66). In order to monitor said positionally fixed rotation, it is generally necessary to consult a second person. Specifically, independent checking is possible only with difficulty. The object of the invention is therefore to provide a practice device (10) with which it is possible to check the position of the imaginary axis independently and without help from further persons in order to be able to practice the optimum golf swing even on one's own. The object is achieved by a practice device (10) according to the invention. The practice device (10) has at least two lateral faces (18, 20) aligned substantially perpendicular to the underlying surface and with a distance between them that corresponds at least substantially to the human interocular distance. By positioning the practice device (10) on the underlying surface (28), it is therefore possible to visually determine even slight lateral deviations from a central ideal position above the practice device (10) by lateral faces (18, 20) that are correspondingly more or less visible.]]></description>

            <description><![CDATA[An apparatus which uses a club having a head portion and a shaft. Integrated with the head portion is a golf ball holder. The golf ball holder is capable of gripping and holding a golf ball with a predetermined force requirement for release, which requires the user to execute a proper golf swing to release the ball. The predetermined force requirement may be adjustable. The user also may vary the angle of the club face on various planes relative to the shaft, thereby changing the swing required to release the ball.]]></description>

            <description><![CDATA[Systems and methods are provided for showing golfers how to aim properly before golf balls are stricken. In one embodiment, a system is provided. The system includes a stand, which forms a lower portion for a golf tee, wherein the stand is configured to rotate freely. Further, the system includes an upper housing, which forms a higher portion for the golf tee. Moreover, an object is included that is physically attached to the upper housing to serve as a pointer for a golfer to hit a golf ball in a direction pointed by the pointer, wherein the direction pointed by the pointer can be changed by rotating the stand.]]></description>
