1. A stock level indication system comprising:
- a shelving unit comprising;
an upstanding back wall;
a plurality of shelves mounted to the back wall, the plurality of shelves each including a product support member having an intermediate portion of the product support member that is deflectable with respect to outer edges thereof, wherein the intermediate portion of the product support members is configured to sequentially deflect as products are stocked thereon such that an amount of deflection of the intermediate portion of the product support member varies with respect to a weight of products stocked thereon;
one or more laser devices mounted adjacent to the shelving unit and oriented to measure distances to the product support members; and
a control circuit in communication with the one or more laser devices and configured to analyze the distances to estimate a deflection of each of the product support members and estimate a weight of products stocked on each of the product support members based on the estimated deflections.

Abstract
In some embodiments, apparatuses and methods are provided herein useful to provide a visual indication of a weight of products stocked on a display assembly, such as a shelf of a shelving unit. The visual indication is provided by virtue of the display assembly having a product support member that sequentially flattens as additional weight is added thereto. A laser device can be mounted proximate to the assembly and oriented to determine a distance to the product support member and a control circuit can be configured to receive the distance and analyze the distance to determine a deflection of the product support member to determine a current stock level.

12. A method for determining a stock level, the method comprising:
-
receiving one or more products on one or more of a plurality of shelves of a shelving unit, the shelving unit including an upstanding back wall and the plurality of shelves mounted thereto, the plurality of shelves each including a product support member having an intermediate portion of the product support member that is deflectable with respect to outer edges thereof, sequentially deflecting the intermediate portion of the one or more of the plurality of shelves as the one or more products are stocked thereon such that an amount of deflection of the intermediate portion of the product support member varies with respect to a weight of products stocked on the product support member; measuring distances to the product support members with one or more laser devices mounted adjacent to the shelving unit; and analyzing the distances with a control circuit in communication with the one or more laser devices to estimate a deflection of each of the product support members and estimate a weight of products stocked on each of the product support members based on the estimated deflections. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
