Abstract: A thin weighing scale having a thickness of less than 25 mm, comprising a first rigid bottom plate, extending along a reference plane defined by a first direction X and a second direction, a second rigid top plate, at least four load cells 4, interposed between the first and second rigid plates, a set of linkages comprising arms, some arms extend in the first direction and some other arms extend in the second direction, each arm having an elongated shape with a first end attached to the first rigid plate and a second end rigidly connected to the second rigid plate, whereby a movement is provided along a third direction, the set of linkages preventing relative movement between first and second rigid plates along the first and second direction.

Abstract: A thin personal weighing device comprising a bottom plate, extending along a reference plane, a top plate movably mounted with regard to the bottom plate along a direction perpendicular to the reference plane, four resilient elements directly interposed between the top and the bottom plate, four LC circuits positioned at a vicinity of an edge of the bottom plate, and a conductive material coating, arranged on the top plate, the four LC resonators and the at least conductive material coating exhibiting an inductance. Movement of the conductive material coating relative to each of the four LC resonators introduces a variation of the inductance. A computation unit detecting the variations of the inductance is electronically coupled with the LC resonators and configured to correlate the variations of the inductance with an actual weight placed on the weighing device. The thickness of the weighing device is less than 25 mm.
