Abstract: A method of manufacturing golf club heads, and particularly putter heads, using metal injection molding and plasma polishing is disclosed herein. The metal injection molding process is facilitated with a base tool having a golf club head shaped cavity and interchangeable hosel core tools. The use of interchangeable hosel core tools allows a manufacturer to quickly and easily alter the overall shape of the putter head, and greatly reduces the number of base tools needed to create an entire line of putter heads with different hosel designs. This plasma polishing process yields a glossy cosmetic shine appearance, increases corrosion and rust resistance, and provides a smoother surface to which post process operations can adhere.

Abstract: A manufacturing assembly and a method for locating a face insert in a golf club head during manufacture are disclosed herein. In particular, the manufacturing assembly comprises a face locating fixture sized to receive a golf club face insert and a pick fixture configured to removably attach to the face insert. The manufacturing assembly may further comprise a holding fixture sized to receive a golf club head and hold it in place while the face insert is aligned with the head during assembly.

Abstract: Method and system for bi-directionally controlling power flow between two separate direct current power sources in a multi-stage power converter system are provided. The method allows providing at least first and second power converter stages coupled in parallel circuit to one another. The method further allows providing a first switching controller coupled to selectively actuate a pair of switching devices in the first power converter stage, and a second switching controller coupled to selectively actuate a pair of switching devices in the second power converter stage. One of the first and second switching controllers is selected as a master controller, and the other one of the first and second switching controllers is selected as a slave controller. An average voltage measurement is determined at a respective node of each the power converter stages. A compensating signal is generated based on the difference of the average voltage measurements at the respective nodes of each of the power converter stages.

Abstract: A pistol-shaped charger assembly clamps a cylindrical radiation dosimeter against one edge thereof. A triggerlike lever on the handgrip of the assembly is manually pivoted to actuate a piezoelectric current generator held in the handgrip and thereby charge the dosimeter.
