摘要： A method and apparatus for counting nominally identical articles employs weighing apparatus, which comprises a load hod (102) for holding a number of articles to be weighed and a load transducer (20) responsive to loading of the hod (102) to produce a derived electrical signal indicative of the apparent weight of articles in the hod (102). The signal is susceptible to fluctuation as a result of local air currents acting on the hod (102) or on the articles contained therein. The transducer derived signal is filtered to extract a component signal representative of such fluctuation. After further processing, the filtered component signal is used to correct the original transducer signal thereby to indicate the true weight of articles in the hod (102). The number of articles in the hod (102) is then determined by dividing the true weight indication by an expected average weight of an article. Fluctuations in the transducer signal due to air currents may also be removed by a system of validation of the signals depending on whether or not they are within range limits based on a running average.
