A method for effecting a kickdown shift in a transmission of an automotive vehicle controls turbine speed change based on a continuous desired acceleration calculation. One exemplary method for balancing power in a synchronous generator system includes determining an output power characteristic of a synchronous generator driven by a prime mover and comparing the characteristic to a value derived from the output power of a plurality of synchronous generators. Portions of the layout representation including structures demonstrating poor manufacturability andor in which extra manufacturability margin is present can be modified to optimize the layout representation. Another aspect includes using the digital light to signal the performer.
