Open the CIPO recordAbstract From the Canadian patent
A system (100) for analyzing respiratory tract sounds in an individual (110). A plurality of N transducers (105) are fixed over the thorax. The ith transducer is fixed at a location xi, and generates a signal P(xi t) , indicative of pressure waves at the location xi for i=1 to N. A processor , (135) receives the signals P(xi,t) and determines an average acoustic energy P(x,t1,t2) at at least one position x over a time interval where P is determined in an algorithm involving at least one of the signals P(xi,t).

Why it's free to use
- Filed January 12, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 12, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 12, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
