Abstract
The pill counter of the present invention, counts pills by measuring the weight of individual or a small number of pills as they gradually drop onto a weight scale. During the time between each pill drop, the count is obtained by comparing the weight of latest pills dropped to the expected weight ranges of one or more pills. The expected weight range includes pill weight variation and weight scale error. When the measured weight is between two expected ranges, there is at least one broken pill in addition to the whole pill count of the lower expected range. The counter adds the count of each pill drop to obtain the total count of the pills. In different approach, whenever there is a change in the reading of weight scale more than the error of the weight scale or a predetermined value, the count of pills is increased by one.
