Open the CIPO recordAbstract From the Canadian patent
A general method of anomaly detection (208) from time-correlated sensor data is disclosed. Multiple time-correlated signals are received. Their crosssignal behavior is compared against a fixed library of invariants. The library is constructed during a training process which is itself data-driven using , the same time-correlated signals. The method is applicable to a broad class of problems and is designed to respond to any departure from normal operation including faults or events that lie outside the training envelope.

Why it's free to use
- Filed March 6, 2002 and granted May 15, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 6, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 6, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
