In accordance with an embodiment of the present invention there is provided a pump assembly used in connection with metering and dispensing fluid. A nut on opposite end of the hollow cylinder limits entry of the cylinder into the bottle. The plurality of candidate objects are preclassified to identify a plurality of composite objects and a plurality of character portions. The system includes a charging capacitor bank, a fast charger for charging the charging capacitor bank in time periods of less than 0. Since an electrode tab is formed by cutting a portion of an electrode current collector and folding upward, deformation of a jelly-roll type battery unit is prevented. A biasing device, such as a spring, is connected to the marker holder to urge the marker holder towards the retracted position.
