Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method for correcting initial sampling of the start bit of the serial bit rate of a filter's output signal particularly of a , writing/reading device for transmitting RF data signals between the writing/reading device and a mobile data carrier. The serial bit rate of the received signal is filtered during a filtering time (F) and the filter's , output signal is then sampled during a first sampling time (A1) and additional sampling times (A2) in subsequent steps. Filtering of the received signal begins when a first edge signal (e.g. of a 1-0 transition) of the received signal is received. An interference is detected when a second edge signal (e.g. of a 0-1 …

Why it's free to use
- Filed November 25, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 25, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 25, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
