Abstract: A method is provided for cold forming center web or webless tapered piston pins in one forming sequence. The method eliminates secondary operations such as but not limited to machining, annealing, coating and secondary forming.The method includes the steps of cutting a metal rod into a substantially cylindrical slug piece, die extruding the slug piece to form a first cavity in the slug piece, optionally die extruding the slug piece to form a second cavity in the slug piece, piercing the slug piece to form the slug piece into a hollow cylindrical piece, die extruding the hollow cylindrical piece at either end to form a hollow cylindrical piece having a taper on an internal surface of the hollow cylindrical piece at either end.

Abstract: In accordance with the present invention, an improved method is provided for synchronizing a pulse stream with a data stream in an optical communications system. The improved method includes: generating an optical data signal for transmission through the optical communication system, where the data stream exhibits a duty cycle less than fifty percent and the optical data signal is formed from the pulse stream and the data stream; detecting an optical power level associated with the optical data signal; and synchronizing the pulse stream with the data stream based on the optical power level associated with the optical data signal. Specifically, the pulse stream is temporally aligned with the data stream when the average power of the optical data signal is maximized.
