Open the CIPO recordAbstract From the Canadian patent
An acoustic shock protection method and device are provided. A pattern analysis-based approach is taken to an input signal to perform feature extraction. A parameter space is identified which is corresponding to the signal space of the input signal. A rule-based decision approach is taken to the parameter space to detect an acoustic shock event. The device may be advantageously implemented using a weighted overlap-add approach to provide low group delay high-fidelity and a high degree of protection from acoustic shock events.

Why it's free to use
- Filed March 31, 2004 and granted January 3, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 31, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 31, 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.
