Abstract From the Canadian patent
A method of increasing the signal-to-noise ratio of a time-dependent scanning signal produced during a periodic scanning operation wherein a defined or bounded and centered field is scanned line-by-line by means of a scanning device, there is produced a time-dependent supplementary or additional signal corresponding to the spacing of the momentarily scanned location from the center of the field and possessing a momentary value r as well as a maximum value R. Successive line scans occur in directions which in each instance differ from one another by a predetermined angle in such a manner that as a function of the line width the neighboring lines successively adjoin one another at the field …

Why it's free to use
- Granted October 30, 1979. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended October 30, 1996.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
