Open the CIPO recordAbstract From the Canadian patent
A signal with several in timely sequence repeatedly occurring states is generated. In order to avoid an attention reduced by habit of an observer, the duration during which at least one of the states occurs is determined by a circuit each time randomly or pseudorandomly. The random duration may be limited by selectable upper and/or lower limits.

Why it's free to use
- Filed April 3, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 3, 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.
