Open the CIPO recordAbstract From the Canadian patent
A process parameter sensor (5) for a material processing system (1) includes a conduit (103A-103B) configured to contain material from the material processing system. A plurality of motion transducers (105A-105D) is operative to produce a plurality of motion signals representing motion at a number of locations on the conduit. An overdetermined process parameter estimator (30) is responsive to the plurality of motion transducers and configured to receive the plurality of motion signals. The overdetermined process parameter estimator is operative to resolve conduit motion into motion attributable to each of a predetermined number of forces and to estimate a process parameter …

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.
