Abstract: An apparatus for weighing containers comprises a stage configured to support a receptacle for securing one or more containers and a singulation post comprising a vertical element positioned below the stage. The singulation post is aligned with and configured to displace a single one of the containers within the receptacle in an upward vertical direction as the stage is translated in a downward vertical direction towards the singulation post. The singulation post is coupled to a load cell configured to measure a weight of the single displaced container while the vertical element of the singulation post contacts the container. The apparatus further comprises a controller for actuating the stage in the vertical directions and for recording a weight of the container measured by the load cell.

Abstract: A modular shelving system has a first wall and a second wall. Extending between the first wall and the second wall is a plurality of rigid bridging members. Each of the walls has a base panel and a detachably connected ancillary panel. An upper profile of the base panel and a lower profile of the ancillary panel vertically interlock to form an interface. A plurality of apertures is formed along the interface when the panels are interlocked. A fastener, such as a screw, can be inserted through each of the plurality of apertures to detachably connect one of the walls to one of the plurality of bridging members. Additional walls and bridging members may be provided to form additional storage modules. Each wall may also be heightened by adding ancillary panels to form a highly accommodating expandable shelving system.
