Open the CIPO recordAbstract From the Canadian patent
A method and system for processing of physiological signals is provided. The system processes information signals in subband-domain associated with the physiological signals in time-domain. The information signals are obtained by one or more over-sampled filterbanks. The method and system possibly synthesizes the subband signals obtained by subband processing. The method and system may implement the analysis subband processing, and synthesis algorithms on over-sampled filterbanks which are implemented on ultra low-power small size, and low-cost platform in real-time. The method and system may use over-sampled Weighted-Overlap Add (WOLA) filterbanks.

Why it's free to use
- Filed September 15, 2005 and granted February 28, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 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.
