    Abstract: A device for electrically measuring a force includes a load cell having a first metal electrode and a second metal electrode disposed opposite thereof in the direction of the force, each having contact surfaces in which the force to be measured can be impressed, and electrical resistance in the range of a few milliohms to less than or equal to ten ohms and a mean roughness value (Ra) of less than or equal to 400 nanometers, for forming force-independent conductivity, a thin insulating film disposed between the first and second metal electrodes in a form-locked manner, a reference metal electrode disposed on a section of the thin insulating film such that it is force-decoupled from the first metal electrode and tensioned with respect to the second metal electrode at a constant retaining force by a fastening element, and a measuring circuit designed as a half bridge or a full bridge.

    Abstract: A load sensor disposed between a first member and a second member to detect a load applied to the first member in an up-down direction, the load sensor includes a strain body including a strain gauge, a first fixation member fixing the strain body and the first member to each other, a second fixation member fixing the strain body and the second member to each other, and a restriction portion restricting a displacement of the strain body in a state where the first member is displaced upward by a predetermined distance relative to the second member based on the upward load applied to the first member.

    Abstract: A system for determining an amount of shelf space comprises: a plurality of weight sensors at a region of a shelf that directly measure a force related to a weight of physical items positioned on the shelf and generates a weight result, the shelf positioned at an angle from a horizontal axis; the shelf positioning the physical items at the angle; a shelf angle determination device that determines the angle of the shelf; wherein the weight sensors generates the weight result adjusted for the determined shelf angle; and an occupancy determination processor that determines an amount of surface area of the shelf occupied by the physical items from the adjusted weight result.
