Open the CIPO recordAbstract From the Canadian patent
The rise-up time of an intermediate frequency signal generated in a radio receiving unit is detected at each time in intermittent receiving operation. The radio receiving unit is turned on for a period including the rise-up time and a time of the intermittent receiving operation. Consequently the electric power consumption of a battery for a power supply of the radio receiving unit is decreased.

Why it's free to use
- Filed February 25, 1994 and granted January 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 25, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
