DEFINITION

Classification: 204/609

Plural rapid changes in direction of electric field (at least 1,000 times total and at more than 1/sec) (e.g., pulsed field, etc.):

(under subclass 608) Apparatus in which the electric field changes direction more than 1,000 times in rapid succession (more than 1 change per second), usually using more than 2 electrodes with synchronized timing of voltage spikes or peaks.
