Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for providing an automated optical robotic polishing system for removing flaws in transparencies such as, transparent canopies (12) used in aircraft. A pneumatic random orbital polishing tool (10) attached to a robot arm (14) is used to polish canopies to remove flaws. The flaws are removed by grinding the area surrounding the flaw and smoothing the flaw site to conform to the contour of the canopy. To identify optimum motions for the polishing tool for grinding to remove the bulk of the plastic material around a flaw, mathematical topology simulation techniques are implemented using various polishing pad pressure profiles and various polishing motions.

Why it's free to use
- Filed May 14, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 14, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 14, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
