Abstract: The present invention provides an improved weigh-in-motion scale. A slight increase in the thickness of a an upper, flexibly-deformable metal plate in a thin, flexibly-deformable plate system coupled with a change in the transverse locations of the load cells provides the improved weigh-in-motion scale, which is capable of weighing substantially heavier loads than previously known weigh-in-motion scales. In use, as weight is applied to the weigh-in-motion scale, the upper flexibly-deformable metal plate elastically bends. The strain gauges thus provide a changing resistive value proportional to the bending of the flexible element and the weight applied, to generate signals to the Wheatstone bridge circuit, which then provides output signals from the Wheatstone bridge circuit, which are proportional to the force applied to the upper flexibly-deformable metal plate.

Abstract: The current invention involves a method and device of combining vehicle scales platforms to eliminate potential checking interferences. Disclosed is a novel method of combining independent scale platforms enabling independent weighing on each platform and at the same time a singular checking system for the combined scale.

This reduces the complexity and associated cost of the combined scale checking system and increases the accuracy of said scale system by eliminating potential checking interferences. This is extremely significant in situations where side checking is inconvenient near where two scales connect, or in pit less and above ground scale designs.

Abstract: The multiple load sensing multi-load cell scale is described that provides improved utility to scales with multiple decks that share load cells near supports so that more than one load may be determined at the same time on a single scale. In more detail, the scale uses the sectional sensitivities to load movement on the scale decks, load position and individual normalized load cell outputs to provide separate load magnitude measurements on these individual decks. According to the present invention, more than two load cells associated to form a single scale provide outputs that are converted to individual digital representations of the relative force magnitude on each. These magnitudes are related to the effective location of each load cell to provide the load centroid location on the scale when the sum of the products of the effective location and magnitude of each is divided by the sum of the magnitudes.

As a load enters the platform, the tipping member pivots against the first stop such that the weight is distributed between the fulcrum and the stop. As the load approaches the center of the platform, the tipping member pivots off of the first stop such that the weight is measurable by the weighing device.

Abstract: A weighing in motion (WIM) apparatus and method in which scale platforms are provided exhibiting a high rigidity selected to achieve a relatively high natural frequency response characteristic. These platforms are combined with instrumentation wherein load cell derived signal outputs are digitized at a conversion or sampling rate effective to permit an identification of amplitude data correlative to vehicle weight. In particular, the sampling rate is selected so as to isolate and detect peak amplitude output of the system which is directly correlatable to truck weight. The invention derives from a recognition that, during the dynamics of movement of a vehicle such as a truck over the rigid scale platform structures, there occurs a decoupling of the mass of the truck from the scale permitting its response to the weight of the truck without significant loss of natural frequency bandwidth.
