Abstract From the Canadian patent
It is possible to improve the hit probability of programmable projectiles by means of this method. For this purpose a predetermined optimal disaggregation distance (Dz) between a disaggregation point (Pz) of the projectile (18) and an impact point (Pf) on the target is maintained constant by the correction of the disaggregation time (Tz) of the projectile (18). The correction is performed by adding a correcting factor, which is multiplied by a velocity difference, to the disaggregation time (Tz). The velocity difference is formed from the difference between the actually measured projectile velocity and a lead velocity of the projectile, wherein the lead velocity is calculated from the …

Why it's free to use
- Filed November 14, 1996 and granted September 16, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 14, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 14, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
