Abstract
A method for dispensing and detecting solid pharmaceutical articles includes: forcing an article through a dispensing channel and past a sensor configured and positioned to detect the article passing through the dispensing channel, wherein the article includes one of the solid pharmaceutical articles; generating a detection signal using the sensor responsive to the article passing through the dispensing channel, wherein the detection signal indicates a time that the article takes to traverse the sensor; and determining whether the article is a complete article or an article fragment responsive to a comparison of the time indicated by the detection signal and an article fragment travel time representing an expected travel time for a complete article to traverse the sensor that is determined independent of physical attributes of the solid pharmaceutical articles.
