Open the CIPO recordAbstract From the Canadian patent
A process parameter (45) such as mass flow is determined in a vibrating conduit process parameter sensor (5) using a complex modal transformation estimated from a plurality of motion signals representing motion of the parameter sensor conduit. According to an aspect of the invention a complex , eigenvector is provided representing motion of the conduit at the plurality of locations at a known mass flow. A plurality of motion signals is received from a plurality of motion transducers, the plurality of motion signals indicating motion at a plurality of locations on the conduit as a material flows through the conduit. A complex modal transformation relating the received plurality of …

Why it's free to use
- Filed June 23, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 23, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 23, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
