Open the CIPO recordAbstract From the Canadian patent
Temperature sensors are located inside drive chambers where disk drives are located to signal an overheating condition. An overheating condition triggers external alarms and produces an interrupt signal to the disk drive controller, which in turn, alerts the operating system. If the operating system does not comprehend the problem and take the appropriate action, the controller shuts down the disk drives after a certain period of time.

Why it's free to use
- Filed October 21, 1991 and granted December 5, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
