Abstract
Efficient static neutralization of an electrostatically charged object that has a varying distance from an ion generating source, a varying velocity, a large dimension or any these is achieved by using an ionizing cell or bar having a first electrode and a second electrode. The first electrode for receiving a multi-frequency voltage that has a waveform, and the second electrode separated from the first electrode by a first distance and for use as a reference electrode. The waveform is adjusted during neutralization of a moving object based on at least one attribute of the object.
