Open the CIPO recordAbstract From the Canadian patent
Simultaneously detecting both frame (52 54) synchronization in a, serial bit stream reduces the time required to have a receiver lock up to a transmitted (100) serial data signal. A dual-phase correlator circuit is used to detect frame synchronization while a multiphase commutator (200) circuit detects bit clock synchronization.

Why it's free to use
- Filed June 17, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 17, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
