Abstract: The scale is of limited height and utilizes Z-shaped flexures between the load frame and support frame. The scale can be placed in a hospital bed for weighing bed-ridden patients or for monitoring weight variations in bed-ridden patients. Each flexure has a Z-shaped cross section with flanges extending to opposite ends of the element for securement to the load frame and the support frame, respectively, of the scale. The web of the flexure is connected to a torsion bar which turns with the flexures in order to produce a read-out signal via an LVDT.

Abstract: The scale is of limited height and utilizes Z-shaped flexures between the load frame and support frame.

Abstract: A flexure scale is made of compact, inexpensive construction and includes a load frame which is supported via flexures from a stationary support frame. The load frame includes two oppositely directed beam arms which are displaced when a load is placed on the load frame. The two beam arms are connected together to permit a summation of their displacements and the longer beam arm is secured at the free end to the support frame by means of a spring which proportionally restrains the displacement of the beam arm. A linear variable differential transformer is mounted on the support frame to emit signals corresponding to the displacements of the beam arms to a digital readout means. The electrical output of this transformer is adjusted to produce a fixed output for a standard load.A system composed of a multiplicity of these scales requires only a single read-out means.
