Abstract From the Canadian patent

A linear electric generator (LEG) includes sections of coils of an induction coil assembly (ICA) disposed along a distance d1 and apparatus for passing a per anent magnetic assembly (PMA) of length d2 where d2 is less than d1, along the coils for generating voltages and power in the coils in close proximity to the PMA. Unidirectional conducting elements are connected between the coils and output power lines to couple the voltages developed across excited coils to the output power lines without the unexcited coils loading down or dissipating the volts e developed across the output power lines.

Why it's free to use

  • Filed March 15, 2005 and granted October 29, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 15, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
