摘要： To a laser that has no tracking error a desired laser modulation current to maintain constant Optical Modulation Amplitude (OMA) is closely proportional to the laser bias current, lb, at any temperature when the laser is under constant power according to embodiments. To a laser that has tracking error a desired laser modulation current to maintain constant Optical Extension Ratio (ER) is closely proportional to the laser bias current, lb, at any temperature when the laser is under constant power according to embodiments. This phenomenon is appears apply to many if not all types of lasers. A laser modulation control is provided that determines a modulation current based on the laser bias current. Thus, embodiments may maintain performance and compensate for temperature changes without the need to actually measure temperature thereby eliminating the need for temperature sensors and their associated parameter vs. temperature look-up tables or dithering techniques used in the past.

摘要： A method for making a disc flange in a wheel rim including the steps of: A. Forming a cylinder for a wheel rim; B. Forming an annular groove concaved inwardly centripetally from a cylindrical wall of the cylinder towards an axis of the wheel rim; C. Pressing the annular groove to be an annular flattened disc flange circumferentially formed in an inside wall of the cylinder; and D. Circumferentially welding along an outer port of the flattened flange as pressed and derived from the annular groove for sealing an interior in the flattened flange; whereby upon surface treatment of the wheel rim and forming of bolt holes through the disc flange, a wheel disc can be secured to the disc flange in the wheel rim by fastening bolts through the bolt holes formed in the disc flange and in the wheel disc.
