Open the CIPO recordAbstract From the Canadian patent
The present invention is directed to improved systems and methods for processing respiratory signals derived generally from respiratory plethysmography and especially from respiratory inductive plethysmographic sensors mounted on a garment for ambulatory recording. The systems and methods provide improved signal filtering for artifact rejection improved calibration of sensor data to produce outputs indicative of lung volumes. Further this invention provides improved systems and methods directed to processing lung volume signals however measured or derived, to provide improved determination of respiratory parameters and improved recognition of selected respiratory events.

Why it's free to use
- Filed April 9, 2004 and granted October 25, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
