  "abstract": "This disclosure describes an arrangement for singulating overlapping parcels on a conveyor system by employing differential roller speeds. Parcels arriving side-by-side or in an overlapped configuration, which prevents individual identification and sorting, are presented to a singulation zone. Within this zone, transport rollers are configured with a speed gradient across the conveying width. This gradient applies differential forces to overlapping parcels, causing them to rotate and separate. The system incorporates mechanisms for gap measurement, handling of excessively wide parcels, and recirculation of items that do not achieve singulation.",
