Open the CIPO recordAbstract From the Canadian patent
A process for analyzing, decomposing, synthesizing and extracting seismic signal components, such as the fundamental of a pilot sweep or its harmonics, from seismic data uses a set of basis functions. The basis functions, may be any of the harmonics or other components derived from the pilot sweep. These basis functions are modulated with the data being analyzed. The resulting, data output from the modulation are then low-pass filtered so that the instantaneous amplitude and differential phase of the particular signal component to be synthesized may be computed. Each targeted component is then synthesized and the result subtracted from the remaining data.

Why it's free to use
- Filed February 26, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 26, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 26, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
