Abstract: In one embodiment, a weighing system includes a base, a platform structure movable with respect to the base, at least one flexure fixedly attached to the platform and the base, the at least one flexure configured to inhibit movement of the platform structure along a horizontal plane relative to the base, and a plurality of load cell assemblies, each of the plurality of load cell assemblies including an upper portion pivotably supported by the base through a first pivot assembly and a lower portion pivotably supporting the platform structure through a second pivot assembly, wherein an axis of rotation of the first pivot assembly is parallel to an axis of rotation of the second pivot assembly.

Abstract: A weighing system has a base, a platform structure, and a plurality of load cell assemblies. The platform structure is movable with respect to the base and includes a planar top surface defining a horizontal plane. Each of the plurality of load cell assemblies includes an upper portion supported by the base and a lower portion supporting the platform structure. Each of the plurality of load cell assemblies is positioned such that when the upper portion of each of the plurality of load cell assemblies is projected onto the plane and the planar top surface is projected onto the plane, each of the projected upper portions is located outwardly of the projected planar top surface. A load on the planar top surface is therefore located between the load cell assemblies.
