Open the CIPO recordAbstract From the Canadian patent
The transmission system is for transmitting signals in burst mode. Transmitters in substations of the system transmit signals in bursts and, in dedicated timeslots, to a main station. The latter station converts the received signals to digital signals by means of a processing circuitry included in its receiver. This processing circuitry performs the steps of an iterative process and, in each step, derives from a received signal Iin a threshold value related to a characteristic of the signal. The power of the transmitted signals is controlled by a circuit that compares the peak power values of a maintenance signal coupled back via a backfacet diode D with reference values REF1 and REF2 and …

Why it's free to use
- Filed September 8, 1993 and granted July 31, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 8, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 8, 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.
