Open the CIPO recordAbstract From the Canadian patent
Strobe control circuitry combines several approaches to limit in-rush current. One circuit limits initial circuit response to an applied voltage that has been switched from an inactive to an active state. Other circuitry switches from a high input impedance state to a low input impedance state a predetermined period of time after the applied voltage has switched to an active state.

Why it's free to use
- Filed January 21, 2002 and granted August 16, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 21, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 21, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
