    Abstract: A load measuring device for a construction machine includes a processing unit for acquiring signals indicative of cylinder pressure of front and rear suspension cylinders via pressure sensors and computing a weight value of a load put on a dump body of the construction machine. When the construction machine is traveling on a curvilinear route, the construction machine makes the output of the weight value ineffective. In particular, when the differential speed value between the rear wheels, received from a speed difference detector, is below a preset value, the arithmetic unit outputs a loading weight W computed by the processing unit, as final loading weight, and so that when the differential speed exceeds the preset value, the arithmetic unit makes ineffective the computed loading weight W as the final loading weight output.

  • Patent number: 7085677
    Abstract: A method, system, and computer-readable medium is described for automatically identifying incongruous item packages, such as to detect incongruities in the items that are included as contents of the item packages and/or to identify incongruities in the packaging used for the item packages. In some situations, the automatic identification of incongruous packages includes initially automatically learning appropriate values for parameters of items (e.g., item weights and/or dimensions) based on automatically measured parameters of packages including those items. Those item values can then be used to estimate corresponding parameter values of sealed packages that contain those items, and to further identify incongruous item packages whose measured parameter values do not correspond to the estimated values for those parameters.

  • Patent number: 6868364
    Abstract: A method for determining the weight of a load upon a load support of a hydraulic lifting device, in which the pressure of hydraulic fluid within a lifting cylinder is measured and a stored reference curve representing the relationship between the weight of the load and the hydraulic fluid pressure is determined by multiple measurements of the pressure resulting from loads of known weight and the reference curve. According to the method, the load support is lifted and lowered during a short period upon operator request or automatically to sense the load before and during load lifting and lowering operations and a plurality of pressure measuring values are obtained. A pair of average values of the pressure measuring values for respectively lifting and lowering is generated, as well as a third average value of the pair of average values. The third average value is then applied to the reference curve for determining the weight of the load.
