Patent number: 8561482Abstract: A sealed sensor includes a test body configured as a deformable simple parallelogram, including a one-piece test body having a generally H- or X-shaped central opening extending therethrough, whose shape determines four hinge positions of the parallelogram, between the end of each arm of the opening and one face of the test body, and the thickness thereof. At least one hinge is a measuring hinge on one side of the test body. The outer face of the body has a recess and housing for strain gauges and circuits. At least one pair of side cavities define therebetween the width of the measuring hinge(s) and the thickness of the sheets of material connecting side edges of this measuring hinge to side edges of the test body corresponding to the hinge, preventing strains generated in the measuring hinges from being affected by strains from the side edges of the test body.Type: GrantFiled: March 19, 2009Date of Patent: October 22, 2013Assignee: S.C.A.I.M.E.

Patent number: 6828515Abstract: The proof body for a weighing apparatus is comprised of a profiled segment and it includes a measuring beam (9) joined at each one of its ends to a respective wing (10a, 10b) which extend substantially perpendicularly to the measuring beam (9) and of which the free side faces (11a, 11b) provide abutment faces. It further includes an abutment beam (13) which is parallel to the measuring beam (9) and which is connected thereto via two ribs (14), this abutment beam (13) being also connected to each one of the wings (10a, 10b) by a web (15) which is substantially parallel to the measuring beam (9). Under such circumstances, a strain gauge (18) affixed beneath the measuring beam (9) is subjected only to contraction strains when a force is applied beneath the abutment beam (13).Type: GrantFiled: February 10, 2003Date of Patent: December 7, 2004Assignee: S.C.A.I.M.E.

Patent number: 6794587Abstract: The hermetically sealed measuring sensor includes a monolithic proof body having at its ends a first and a second non-deformable parts connected together by a central part designed as a deformable parallelogram. This central part has two through openings defining between them a main beam of which at least one end is joined via a connecting section to a measuring beam which performs one piece with a non-deformable part of the proof body, but is uncoupled mechanically there from. At least one of the non-deformable parts has at least one cavity of which one wall is formed by the measuring beam and by two membranes situated one on each side of this measuring beam. Strain gauges are fixed inside the cavity on the back of the measuring beam and the cavity is closed by a cover which is welded, bonded, or fixed tightly to the corresponding non-deformable part.Type: GrantFiled: October 21, 2002Date of Patent: September 21, 2004Assignee: S.C.A.I.M.E.

Publication number: 20030111277Abstract: The hermetically sealed measuring sensor includes a monolithic proof body (1) having at its ends a first (2) and a second (3) non-deformable parts connected together by a central part designed as a deformable parallelogram. This central part of the proof body (1) has two through openings (6, 7) defining between them a main beam (10) of which at least one end is joined via a connecting section (13) to a measuring beam (12) which forms one piece with a non-deformable part (2, 3) of the proof body, but is uncoupled mechanically from the same. At least one of the non-deformable parts (2, 3) of the proof body has at least one cavity (4, 4′, 22) of which one wall is formed by the measuring beam (12) and by two membranes (15) situated one on each side of this measuring beam (12).Type: ApplicationFiled: October 21, 2002Publication date: June 19, 2003Applicant: S.C.A.I.M.E.

Patent number: 6373002Abstract: A damper for a weighing device including a cavity 4 in which a plate 12 can move, which plate is designed for being connected to a weight measuring device 2. The cavity 4 is closed tightly by a flexible membrane 14 and is partly filled with an oil, while leaving a volume of air or of a gas between the top 14a of the oil and the membrane 14, the plate 12 being totally immersed in the oil. The lower surface of the plate 12 and the bottom of the cavity 4 have shapes which are not planar and which are not parallel to each other, thus preventing the formation of a thin film of oil between them. The peripheral surface of the plate 12 and of the peripheral wall of the cavity 4 define therebetween a first constriction 15 of which the transverse section is constant whatever the position of the plate 12 in the cavity 4.Type: GrantFiled: June 27, 2000Date of Patent: April 16, 2002Assignee: S.C.A.I.M.E.S.A.Inventors: Jean-Pierre Aumard, Jean-Claude Navarro

Patent number: 6318185Abstract: The invention is concerned with a compression stress sensor having a proof body (1) and strain gauges (7) connected together to form a Wheatstone bridge. The proof body (1) is made as a single piece from a monolithic rod which is cylindrical or prismatic with a circular or a regularly polygonal transverse section. This rod (1) is traversed in its median part by at least one pair of passages (3, 4) orthogonal one with respect to the other and located in a plane perpendicular to the longitudinal axis (X) of the proof body (1) to define between them independent measure columns (5). The end faces (2, 2a) of the proof body provide bearing faces receiving the forces to be measured and a strain gauge (7) is fixed to a surface of each independent measure column (5).Type: GrantFiled: August 16, 1999Date of Patent: November 20, 2001Assignee: S.C.A.I.M.E.

Patent number: 4785673Abstract: The sensor is formed of a hollow profile (1) of rectangular cross-section, which has two symmetrical transverse notches (2, 3) and two other symmetrical transverse notches (4, 5) at a distance from the first. These notches pass through the thickness of the large side walls (6) of the profile and, in the case of each pair (2,3 and 4, 5), leave intact but mechanically weakened regions (8) between them, to which strain gauges (9) are fixed.Type: GrantFiled: December 10, 1986Date of Patent: November 22, 1988Assignee: S.C.A.I.M.E.Inventor: Jean-Pierre Aumard

Patent number: 4694922Abstract: A force-measuring device (1) supplies measured force values electrically to a control and calculating device (2). The latter stores the values received in this way and calculates sliding averages therefrom; it controls a display device (3) whose purpose is to give a graphical display of the successive values measured by the force-measuring device (1), or of the successive sliding averages of these successive measured values.The instrument has the advantage of visualizing the variation of a force with time, which is very useful in the case of the force developed by a user on a physical training apparatus, or in the case of the change of the weight of a subject with time.Type: GrantFiled: December 27, 1985Date of Patent: September 22, 1987Assignee: S.c.a.i.m.e.Inventor: Guy Mairot

Patent number: 4582151Abstract: A weighing apparatus designed to be included into an element insertable beneath a bench comprising a covering plate (2) resting by two of its sides on at least one face of the insertable element, a weighing scale (3), a readout panel (4), means for displaying the measured weight located in the plane of the upper surface of the plate (2). The edge of said upper surface fits with the edge of the upper surface of said element and the plate (2) is used as supporting means for the weighing mechanism.Type: GrantFiled: December 7, 1984Date of Patent: April 15, 1986Assignee: S.C.A.I.M.E.Inventors: Guy Mairot, Claude Perruche
