Abstract From the Canadian patent

An electrodynamic motor drive system, for generating enhanced rotational output, is, comprised of a pair of flywheel mechanisms that are integrally connected to an output, shaft. Each flywheel mechanism is energized by its own motor and is operable to, temporarily engage a weighted mass that travels a path defined by the housing of the, system. A pair of mass accelerators rapidly advances each flywheel mechanism during, the transfer of the masses from one flywheel mechanism to the other. A component of, the force generated by the continuously rotating masses is transferred through each, flywheel mechanism to an output system which in turn, causes rotation of an , output shaft.

Why it's free to use

  • Filed May 27, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 27, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 27, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
