A replicate can be secured to a blister package intended to contain articles, such as pills, and is used to record the removal of individual articles from the blisters. To remove an article from a blister one will usually press against the blister to push the article through a frangible closure seal, breaking the seal in the process. The replicate includes a backing sheet which carries a plurality of traces alignable with corresponding blisters so that when the article is removed from the blister it will not only break the seal but it will also break the corresponding trace. All of the traces are connected to an integrated circuit which may also be formed or provided on the backing sheet, as is a power source for the integrated circuit. The breaking of the trace is an event that is recorded in the integrated circuit for later accessability. The replicate may be secured to the blister package after the package has been produced by conventional form-fill-seal equipment. The individual traces can be formed into a grid of closely spaced traces so that alignment of the traces with the individual blisters is less critical. The replicates may be formed by printing or other conventional methods on a roll of lidstock. After forming the individual replicates are severed from the roll of lidstock for securement to a blister package.

The invention relates to a novel surge control circuit and belongs to the technical field of electronic circuits. A relay rapidly works and is closed at the moment of powering-on. A power supply supplies power to a load through a thermistor NTC. Because of the characteristics of the thermistor NTC, supply current is kept in a stable and constant current state. When a capacitor in a load circuit is charged and works stably, the relay is opened, the power supply supplies power to the load through the normally-closed contact of the relay. Since the thermistor NTC and the normally-closed contact of the relay are connected in parallel, the thermistor NTC is disconnected and stops working. By detecting input voltage through an instantaneous comparison amplifier, when the power supply is turned off and is turned on again, the instantaneous comparison amplifier can output a resetting signal to reset a time-delay switching circuit, so as to ensure that the switching time of a time-delay switch is stable and the misoperation is eliminated when the time-delay switch is turned on or off at each time. Therefore, the requirement on the instantaneous power of the power supply is reduced, the damage rate of the thermistor NTC is greatly decreased, the power supply cost is reduced, the power consumption is extremely low because the novel surge control circuit is in a static state after surge control work is completed, and the common practicability and the good economic and technical efficiency are realized.
