Abstract:
1. A mailpiece weight measuring apparatus for use with a mailpiece processing system that transports mailpieces at an initial velocity (V 0 ); the mailpiece weight measuring apparatus comprising: means for determining a first velocity (V means for imparting a force to the mailpiece in a direction co-linear with said first velocity as it enters the mailpiece weight measuring apparatus, so that the mailpiece exits said force impacting means at a second velocity (V means for determining the second velocity (V means for determining a change in a parameter (Δp), said change being proportional to the force imparted to the mailpiece by said force imparting means; and means for determining the weight of the mailpiece (m) based upon the determined first velocity (V wherein the force imparting means comprises a first roller and a second roller positioned relative to each other so that a mailpiece is pinched between the rollers when it travels between them; wherein the means for determining a change in a parameter (Δp) comprising a logical device in communication with a rotational encoder monitoring the first roller, said logical device capable of deriving a change of angular velocity of the first roller based on signals from the rotational encoder.
