Abstract From the Canadian patent

The invention uses one inductor, which is formed of one two or a few twisted , or , parallel conductors and exposes a sample object in a pulsed and damped alternating magnetic , field (B) without necessarily the employment of a second constant intensity, magnetic field. , In this way the nuclei and/or the electrons of the sample object are activated, in the presence , of a non-constant magnetic field (B) that gets infinite negative and positive values between , successive damped positive and negative values crossing through the zero , value during a magnetic pulse. Thus, a wide nuclear NMR and electronic EPR multiple - resonance of the , sample object, is achieved.

Why it's free to use

  • Filed June 29, 2004 and granted October 9, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 29, 2024.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 29, 2026.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
