ABSTRACT:
A scale for fast determination of weights including a platform and load cell transducer. Output of the transducer is converted to a digital signal, processed by a low pass digital filter, and weights computed as a function of the sequence of digital signals by means of an algorithm which compares a first estimate of the weight to the break points of a postal rate chart and user the first estimate if it is not within a predetermined distance of a break point, and otherwise determines a second, more accurate estimate. The platform and transducers are combined to form a structure which does not have any significant resonance below the cut off frequency of the filter.
