Abstract: A reconfigurable material moving attachment for a vehicle includes a blade having a blade working face directed toward a front of the blade; and a coupling mechanism for reversibly mounting the blade to the vehicle. The coupling mechanism includes a first coupling portion fixed to the blade and a second coupling portion attachable to the vehicle. The second coupling portion is releasably interconnectable with the first coupling portion in: (i) a forward pushing configuration, in which the blade working face is directed away from the vehicle for pushing of the blade during forward operation of the vehicle to collect and push material in a material collection space adjacent the blade working face, and (ii) a back-dragging configuration, in which the blade working face is directed toward the vehicle for pulling of the blade during reverse operation of the vehicle to collect and back drag material in the material collection space.

Abstract: On-the-shelf retail inventories are managed by periodically processing point-of-sale data to determine the number of units that have been sold during a specified period, and comparing the number of units that have been sold to a historical value. An alert is issued to a store when the difference between the comparison indicates that certain items are not selling at the expected rate.
