The present invention relates to a control unit for controlling a chassis system between at least a ground contact point and a frame of a vehicle, the chassis system comprising a leaf spring and a chassis arrangement, said chassis arrangement is adapted to receive a chassis condition input signal and to control a chassis condition of said chassis arrangement in response to said chassis condition input signal, said chassis system further comprising a strain gauge adapted to issue a strain gauge output signal indicative of a strain in said leaf spring, wherein said control unit is adapted to receive said strain gauge output signal and to issue said chassis condition input signal to said chassis arrangement on the basis of said strain gauge output signal. The invention also relates to a method, a chassis system, and a vehicle.

A vehicle weight sensing system particularly useful for trailers. An axle tube is mounted to the vehicle or trailer through its suspension members that may be leaf springs. A mounting block is affixed to the axle tube for mounting a strain gauge. The mounting block is fixed to the axle tube between the suspension members connected to the axle tube. The mounting block has a mounting surface opposite to the mating surface and a notch extends from the mating surface toward the mounting surface. The notch terminates between the mating surface and the mounting surface. The notch separates rigidified sections of the mounting block and the rigidified sections straddle the notch. The stain gauge measures strain in the axle and thereby generates a signal proportional to the weight on the trailer. The signal can be used to properly proportion a brake system on the trailer.

An assembly including a load cell body having contiguous cutout windows, each formed by a pair of cutout lines and connected by a cutout base, the second window being transversely bounded by the first window,; measuring beams, disposed generally along edges of the body, each defined by a respective line of the first pair of cutout lines; first and second arrangements, each having a pair of flexure beams connected by first and second bases, respectively; a loading element, extending from the second base; and strain gages, attached to the beams, and a transverse flexural arrangement.

The strain gage includes: a substrate formed from a resin material: a resistor provided on a surface of the substrate; and a fusion layer provided on an opposite surface, to the surface on which the resistor is provided. The fusion layer is a thermoplastic polyimide layer. There is provided the strain gage that has a thickness of as thin as possible and that makes a manufacture process of a load sensor simpler.

A shelf bracket assembly mounted upright on a vertically disposed shelf has: a load cell; an anchor; and a cantilever supporting a shelf panel. The cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed frame or a vertically disposed metal plate and a mount for the load cell. The load cell has a monolithic measuring body that has: a force-supporting section; a force-introduction section; and a linkage section between the force-supporting section and the force-introduction section. The force-supporting section of the monolithic measuring body is laterally attached to the mount. The monolithic measuring body has at least one mounting hole through which the monolithic measuring body is attached to the mount with a screw extending horizontally through the monolithic measuring body.

The invention relates to apparatuses for the wheel-by-wheel weighing of railway wagons during motion. Essence: the scales comprise deformation sensors (2), temperature sensors (3) secured to working rails (1) by an adhesive process, polymer plates (6), metal plates (7) and controllers which are arranged externally to a rail track. Circuit boards (5) of the controllers are arranged on the working rails (1) in recesses formed by the polymer plates (6) and metal plates (7). Furthermore, the deformation sensors (2), temperature sensors (3) and circuit boards (5) of the controllers are hermetically encapsulated by means of said set of plates (6, 7). Technical result: simplification of the design and installation of scales and reduction in the probability of electrical interference in measuring networks.

A weighing scale (1) for a retail store counter includes a housing (2), a load-receiving platform (3) on top of the housing, and operating components (27) enclosed therein, including a weighing cell (24). A load-transmitting mechanical connection (25) couples the weighing cell to the load-receiving platform. Analog and digital weighing electronics convert electrical weight signals of the weighing cell into digital weighing results. A touchscreen display panel (7, 22, 23) interacts with a human operator, and is configured as a layered assembly with a liquid crystal display (23), a projected capacitive (PCAP) touch screen (22) with a plurality of touch-sensing points, and a protective glass plate (21) on top of each other. The layered assembly is integrated horizontally in the load-receiving platform facing the human operator.

A platform load sensing system connected between a boom and a platform includes an upper bearing link connecting the boom side to the platform side, and a lower bearing link connecting the boom side to the platform side. The upper and lower bearing links are configured to allow for relative motion between the boom side and the platform side. A load member is secured to the platform side between the upper and lower bearing links, and a load cell is secured to the boom side. A load moment on the platform side is functionally eliminated by the upper and lower bearing links, and a vertical load on the platform side is transferred through the load member to the load cell.
