Open the CIPO recordAbstract From the Canadian patent
The various designs of capacitive or inductive coupling/decoupling fitted on cables in a medium voltage network are known the inductive coupling , circuits constantly inducing current in the sheath of the electric cable. The invention aims at obtaining ranges of capacitive coupling/decoupling for an , inductive coupling circuit. Therefore an inductive coupling unit comprising a ring , enclosing the sheathed electric cable and a coil coupled to said ring by , induction , and connected to a transmission and reception device is designed such that, upon , transmission the current of the message signal is directly induced in the conductor , and, upon reception, only the conductor current is …

Why it's free to use
- Filed July 11, 2004 and granted October 8, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 11, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 11, 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.
