A measuring device, such as a ruler, tape measure, etc. The flip-top closure base portion includes an integrally molded first hinge structure for connecting the flip-top closure base portion to a second hinge structure on a flip-top closure top to create the flip-top closure for the container. 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. The resin article may have improved mechanical and surface characteristics. The system determines that the cooling fluid outlet temperature sensor has possibly failed if the cooling fluid outlet temperature is greater than the average end cell temperature and the cooling fluid outlet temperature minus the average end cell temperature is greater than a predetermined temperature value. The electronic ballast system includes a circuit that allows for a fluorescent lamp to be energized without the preheating of its cathodes, a circuit for power factor correction that makes use of an average current mode implemented by a pulse-width modulator in order to derive a power factor that approaches unity for the electronic power circuit.
