An active diode driver for operating a switch of an active rectifier using an active diode is provided. The invention comprises, in response to a request from a user, opening a log file and noting an entry associated with a message of interest. A torque distribution of the drive train, namely a torque distribution between the drive axles of the drive train andor a torque distribution between the wheels of the drive axles, can be determined and visualized for a driver. The entire method is a cold batch process. ; and said polyester resin has a glass transition temperature ranging from 50\xb0 C. The lower-dimensionality representation may convey information indicative of pitch dynamics between the first and second audio sample.
