Abstract:
A method of weighing a moving object, wherein the method comprises the steps of:(a) sampling the output of at least one sensor, the sensor sensing the force applied to a scale, the sampling being at a rate sufficient to ensure a succession of samples taken during a period of time when the object is supported by the platform; (b) storing the sample outputs in a buffer; (c) receiving a signal from an object detection sensor indicating the presence of an object on the platform; (d) calculating the weight of the object with a microprocessor based upon a predetermined number of the last samples stored in the buffer; and wherein the calculation process for an object is accomplished using values collected before the object detection sensor signals the presence of an object on the platform in step (d) and wherein a single signal is sent to the microprocessor for each object detected on the platform.
