Open the CIPO recordAbstract From the Canadian patent
Particle produced pulses are evaluated on an individual basis for shape symmetry, with significantly asymmetric pulses becoming subject, to editing, i.e. exclusion. Pulse symmetry is determined by measuring the areas under the pulse before and after the first pulse amplitude peak and then by comparing those pulse areas with respect to pre-established limits which are not based upon any of the pulses then being evaluated.
