# Stacked-package detection system

## Abstract

A stacked-package detection system for a matrix sorter detects stacked packages by comparing weight or dimension measurements on primary sorters from those measurements on secondary sorters. Weight or dimension increases for a package on a secondary sorter indicate a stack of packages. A recirculation system diverts packages identified on the secondary sorters as stacked packages back into bulk flow to be reprocessed by the primary or secondary sorters.
