Patent ID: 8403452

Claim:
A method of creating a multipulse burst for a jet, comprising: sending a first test pulse and a second test pulse of a two pulse burst to a jet; measuring a velocity of fluid in the jet caused by the second test pulse of the burst; incrementally increasing a time between the first test pulse and the second test pulse of the two pulse burst; measuring a velocity of fluid in the jet caused by the second test pulse of the burst after the time has been incrementally increased; plotting a time between the first test pulse and the second test pulse against velocity to form a plot, wherein the plot is based on a plurality of incrementally increased times between first and second test pulses; finding a first velocity peak and a second velocity peak in the plot; and creating a multipulse burst, wherein a time between a first burst pulse and a second burst pulse in the multipulse burst is a time from 0 to the first velocity peak in the plot and a time between the second burst pulse and a third burst pulse in the multipulse burst is a time from 0 to the second velocity peak in the plot.
