A modular electronic control system for a geared multiple-ratio transmission wherein pressure profiles for each ratio shift actuator are used to provide seamless transitions during both positive and negative engine torque conditions to improve shift feel and responsiveness to ratio change commands. A distortion correction circuit corrects optical distortion contained in digital image data obtained by photographing conducted via a lens. Preferably, once the location of the point of incidence of the radiation has been determined, image processing techniques are applied to remove the diffraction spots. The amines may be primary, secondary, tertiary or a blend thereof or may be a compound having a structural combination of primary, secondary andor tertiary amines. The fault tolerant system further includes a fault recovery mechanism for recovering from the failure detected by the fault detection mechanism. The method may also include repeatedly dividing a user set into clusters to obtain a best power allocation.
