Open the CIPO recordAbstract From the Canadian patent
Combining signal images includes receiving signal images and performing the following to yield a weighted sum for at least one signal image. A phasor is generated from a signal image in accordance with a correlation reference and a phase alignment of the signal image is adjusted to yield an adjusted signal image. A signal magnitude estimate is determined in accordance with the phasor and a weight is determined in accordance with the signal magnitude estimate where the weight reflects a signal-to-noise ratio of the signal image. The weight is applied to the adjusted signal image to yield a weighted sum for the signal image. The weighted sums are combined to yield a combined signal output.

Why it's free to use
- Filed August 14, 2002 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 14, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 14, 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.
