Many parts of the world have anti personnel (AP) landmines (APLs) buried in their earth, which pose a great deal not only to fighting forces but also to civilians. , For any imaging system, detection of APLs is non trivial since APLs are typically relatively small, compact objects that are buried in a similarly dense medium such as earth. , Improved, explosive device (IED) detection may prove to have more potential than detection of, APLs in view of the increasing worldwide terrorist activity.

Why it's free to use
- Filed April 30, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 30, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
