Abstract From the Canadian patent

Lightwaves (1), which carry data signals and beacon light are used for establishing a connection between a receiver and a transmitter located remote from the former. An acquisition sensor (171) is provided for acquiring the lightwaves (1) in the receiver which generates acquisition sensor signals (Sc) from the receives lightwaves. The lightwaves (1) which are conducted over a telescope (2) and a beam splitter (R4) are fed to the acquisition sensor (171) as well as to a scanning device (5). Besides useful signals (Sa Sb), an additional signal (Sw, Sm', Sm) is obtained with the aid of the scanning device (5) which is used for making the acquisition easier.

Why it's free to use

  • Filed November 3, 2000 and granted January 4, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 3, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 3, 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.
