Abstract: An apparatus and method for determining the total weight of a vehicle either statically or dynamically using the same weight scale. The apparatus is a weight scale for weighing vehicles that is of sufficient length that a plurality of axle sets of a vehicle can be located on the weight scale simultaneously. The apparatus senses the total weight of the vehicle as a function of time within the period of time the vehicle is on the weight scale. The apparatus obtains the vehicle weight statically if all of the axle sets of a vehicle are located on the weight scale simultaneously and the vehicle is in a stopped condition and obtains the vehicle weight dynamically if all of the axle sets of the vehicle are located on the weight scale simultaneously and the vehicle is moving on the weight scale.

Abstract: A commercial-transaction weighing instrument (110) subject to W&M legal controls, configured with a weighing platform (12), at least one load cell (16), a controller (120) with weight-processing (122) and communications (124) modules, and software to be implemented on a general-purpose computer with display and data entry capabilities. The general-purpose computer itself is not subject to legal controls. The weight-processing module receives data from the at least one load cell and generates output data in the nature of weight and legally-required weighment information. The communications module receives the output data of the weight-processing module and further transmits the data to a general-purpose computer (136). Software implemented on the general-purpose computer has program code for establishing encrypted bidirectional communication with the communications module and to operate as the primary display device for the weighing instrument.

Abstract: Embodiments of the invention generally relate to weighing scale diagnostic methods employing a comparison of like component operating parameters. In certain embodiments, weighing scale component output signals may be analyzed to calculate the difference between any two current weighing scale component operating parameter values, and the calculated difference may be compared against a maximum allowable difference for determining if a problem exists. Alternatively, a statistical analysis may be performed that considers the output signal of a given weighing scale component relative to the output signal of another weighing scale component or to the collective output signals of all of the other weighing scale components, and the comparison may be used to determine if a problem exists.

Abstract: Embodiments of the invention generally relate to weighing scale diagnostic methods employing a comparison of like component operating parameters. In certain embodiments, the difference between any two current operating parameter values may be compared against a maximum allowable difference, and/or the deviation of current operating parameters from a calculated measure of central tendency may be determined and compared against a maximum allowable deviation. Alternatively or additionally, a standard statistical test for outliers may be employed. An outlying difference or deviation may be indicative of a problem with the associated component. In other embodiments, the current operating parameters of like components may be compared against calibrated parameters and any deviation of the current parameter for a given component may be compared against the total deviation to determine the percentage of deviation attributable to that component.
