US Patent 10130177 Stock level indication apparatus and method

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 with a curved configuration 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.
