Abstract: Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: a shaft adapter, a collet, a ferrule, and a club head having an interior chamber. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft may be bent or otherwise extend at an angle from the shaft adapter so as to allow adjustment of the shaft position with respect to the club head.

Abstract: A golf club may have an orientation marker located on the golf club that indicates at least a relative orientation between the golf club head and shaft. The orientation marker may be located, for example, on the golf club head or shaft. A key member provides additional information with respect to the relative orientation between the golf club head and the shaft. The key member may be located, for example, on the golf club head, shaft, or grip portion, or on a head cover for the golf club head.

Abstract: A fitting system cart is provided for golf club heads and shafts which have releasable connections between the golf club head and the shaft. The fitting system cart includes a base with a back panel, two side panels, and a top panel which all define an interior portion, a shaft container, and a set of golf club head cases. The fitting system cart may include two door panels connected to the base and movable between an open and closed position. The fitting system cart may include a set of cases for carrying golf club heads. The cases may have a bottom portion for holding golf club heads and a top portion connected to the bottom portion, wherein the top portion rotates between an open and a closed position. The shaft container may have a configuration wherein the shaft container is closed, and a configuration wherein the shaft container is open.

Abstract: Golf club fitting systems and methods include: (a) receiving input data indicating a golfer's driver loft angle and shaft flexibility characteristic; (b) determining initial candidate fairway wood clubs based on this data; and (c) identifying the initial candidate fairway wood clubs. Such systems and methods further may include: (d) receiving launch monitor data generated when the golfer hits balls using the initial candidate fairway wood clubs; (e) determining and identifying additional candidate fairway wood clubs for testing; (f) receiving launch monitor data generated when the golfer hits balls using the additional candidate fairway wood clubs; and (g) determining and identifying a recommendation for a final first fairway wood club based on the data. Other clubs in the fitted set also may be determined by these fitting systems and methods.

Abstract: Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: (a) a cylindrical structure having a cylindrical interior chamber for receiving a golf club shaft, a rotation-inhibiting structure, and a securing structure; and (b) a securing system for releasably engaging the securing structure.

Abstract: Embodiments of the present invention relate to instruction fetching in data processing systems. One aspect involves a data processor (202) to execute instructions and to fetch instructions from a memory (208) according to a fetch size. This data processor (202) comprises a first input (212) to receive instructions, control logic (402) to decode the instructions, and an instruction pipeline (400) coupled to the first input (212) and the control logic (400). The instruction pipeline (400) is responsive to a first signal (214) to set the fetch size to one of a first size and a second size. The data processor (202) therefore allows an instruction fetch policy to be altered based on the characteristics of an accessed device in order to achieve improved performance.

Abstract: A golf club shaft is provided including a metal tip section and a composite butt section. The butt section includes a reduced diameter portion telescopically received within an axial bore of the tip section. An adhesive is disposed between the tip section and the butt section to secure the two together. An insulating layer may be disposed between the tip section and the butt section to prevent galvanic corrosion.

Abstract: A nonvolatile memory (28) in a data processor (10) is capable of being progressively programmed and/or accessed in a user determined number of sections. A user can program and/or access what appears to the user to be reprogrammable nonvolatile memory (28) at a same address when in actuality the user is programming and accessing sequential sections of nonvolatile memory (28). Nonvolatile information stored in nonvolatile control bits (20) is used to control which section of the nonvolatile memory is connected to a communication bus and is thus accessible to the user. When the user desires to write and/or access a new section of nonvolatile memory (28), either the user directly asserts one of the nonvolatile control bits (20) using software, or the nonvolatile control (24) asserts one of the nonvolatile control bits (20) using hardware.
