First Claim
1. A discrete object dispensing system for dispensing discrete objects, comprising:
- a) a plurality of chambers, each including a discrete and predetermined number of objects;
b) means for inputting a number of said objects to be dispensed; and
c) means for releasing the predetermined number of discrete objects from a subset of at least two of said plurality of chambers for supply to a container, the addition of the predetermined number of objects from said subset of said plurality of chambers equalling said number of objects to be dispensed.

Abstract
A discrete object dispensing system and method dispenses any selected number of objects, up to a maximum number, without a delay associated with counting the tablets. A preset number of objects are counted and stored in dedicated chambers, the combination of the numbers of objects within the chambers being known to comprise any number of objects which is desired for dispensing. According to a preferred system, n chambers are provided, with 20, 21, 22, . . . , 2n−1 tablets provided respectively in the individual chambers. The chambers which together add up to the selected number for dispensing are emptied. Only those chambers which are emptied after dispensing need to be refilled and, as such, only the number of tablets in those storage locations need to be counted. The system may include a plurality of cells, each including a plurality of chambers for a different solid dose medication.
