Open the CIPO recordAbstract From the Canadian patent
A low profile acoustic array (10) is configured to selectively respond to shear waves while rejecting compression wave energy in the frequency range of interest. One sensor array is configured as a linear strip with a frame segment, having at least one longitudinally extending rail and a plurality of sensor elements, (20) extending therefrom. These sensor elements have a resilient core and opposing PDVF outer layers configured with opposing polarities onto the core.

Why it's free to use
- Filed February 29, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 29, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 1, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
