Abstract From the Canadian patent

A method and apparatus for increasing the probability of successful data frame transmission from a transmitter to a receiver. When a data frame is generated by a processor (210), it is stored in a transmit queue (212) and a copy of the data frame is stored in a secondary queue (214). An elapsed time device (220) tracks the elapsed time that the data frame copy has been stored in the secondary queue (214). When no data frames are generated by the processor (210), data frame copies from the secondary queue (214) are placed into the transmit queue (212), thereby increasing the redundancy of transmitted data frames and thus the probability of successful transmission to the receiver.

Why it's free to use

  • Filed July 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 14, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 14, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
