The continuous bipolar mechanical output of a nonrectifying transducer is synthesized when the electrical segments 2 of a rectifying transducer are alternately switched into and out of a resonant loop in synchronism with polarity changes of the alternating drive signal. The known extraordinary transduction...http://www.google.fr/patents/US5241233?utm_source=gb-gplus-shareBrevet US5241233 - Electric drive for a rectifying segmented transducer
