ABSTRACT:
A medication dispenser that includes a receptacle having a counting compartment with a first opening into the receptacle and a second opening through which the pills are dispensed. To be dispensed, the pills must passthrough the counting compartment and are counted during such passage. Both openings are blocked or unblocked by logic built into or remotely connected to the dispenser, which logic determines whether the pills in the compartment should be dispensed. In one embodiment of the dispenser, the pills are counted by sensing the amount of light that is passed through the compartment. The logic counts the pills by subtracting the amount of light transmitted through the compartment when it contains pills from the amount of light transmitted through an empty compartment and comparing the result to the known size of the pills. In an alternative embodiment, the pills are weighed in the counted compartment and the weight is compared to the known weight of a single pill. In a second alternative embodiment, radiation emitted by the pills is counted with a radiation detector.
