To group items in an array, gap data are obtained indicating gaps between items. The gap data are used to obtain threshold data which are then used, to obtain grouping data.

The threshold would produce a number of groups of the items that is stable across a range of thresholds and the range of thresholds meets, a criterion for largeness of a range.

Why it's free to use
- Filed October 14, 1994 and granted October 5, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 14, 2014.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
