Patent ID: 10930383

Abstract:
A blister pack for dispensing medication comprises a substantially flat backing, a plurality of blisters formed on the backing, first and second sets of conductive traces applied to the backing, a plurality of breakable resistive traces applied to the backing, and a controller adapted to detect breakage of the resistive traces under the blisters by measuring the voltage across each of either the first set of conductive traces or the second set of conductive traces. The blisters are arranged in a grid comprising rows of blisters and columns of blisters. Each of the first set of conductive traces is associated with one of the rows of blisters. Each of the second set of conductive traces is associated with one of the columns of blisters. For each blister, one or more of the resistive traces are applied to the backing under the blister to form a subcircuit, and the subcircuit connects one of the first set of conductive traces with one of the second set of conductive traces.
