A control device that is constructed in the form of a plug adaptor that can interrupt the power to the dryer when the load is dry. The pattern of the change in power consumption levels of the dryer is used together with a, control algorithm, to provide the information needed for the control decision. The device provides a superior means of determining the cycle termination point which could also be incorporated directly into dryers at the point of manufacture.

Why it's free to use
- Filed April 9, 1992 and granted August 18, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
