A permanent magnet startergenerator subsystem configured in a fault tolerant architecture is described herein for small engine applications. The method has the steps of activating an acoustic shock wave generator or source to emit acoustic shock waves; and subjecting the substance to the acoustic shock waves stimulating said substance wherein the substance is positioned within a path of the emitted shock waves and away from a geometric focal volume or point of the emitted shock waves. Candidate teams of which the average level values are almost equal and which completely differ as to the players belonging thereto are determined as opposing teams.
