Open the CIPO recordAbstract From the Canadian patent
The fiber-optic transceiver system combines EIA-232 data with IRIG-B time code information in a time multiplexing arrangement. The combined signal is transmitted to a receiver where the time code information is decombined from the data so that the two, signals are replicas of their originals. The time multiplexing is accomplished by inserting a pulse into the data stream following the occurrence of a minimum time for each data bit and the coincidence of a time code pulse.

Why it's free to use
- Filed April 24, 1997 and granted July 9, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 24, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 24, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
