This will flush out any particles on the person inside the machine then analyze and identify them in seconds.

Famous quotes containing the word process:
“By Modernism I mean the positive rejection of the past and the blind belief in the process of change, in novelty for its own sake, in the idea that progress through time equates with cultural progress; in the cult of individuality, originality and self-expression.”
—Dan Cruickshank (b. 1949)
“At last a vision has been vouchsafed to us of our life as a whole. We see the bad with the good.... With this vision we approach new affairs. Our duty is to cleanse, to reconsider, to restore, to correct the evil without impairing the good, to purify and humanize every process of our common life, without weakening or sentimentalizing it.”
—Woodrow Wilson (1856–1924)
“I’m not suggesting that all men are beautiful, vulnerable boys, but we all started out that way. What happened to us? How did we become monsters of feminist nightmares? The answer, of course, is that we underwent a careful and deliberate process of gender training, sometimes brutal, always dehumanizing, cutting away large chunks of ourselves. Little girls went through something similarly crippling. If the gender training was successful, we each ended up being half a person.”
—Frank Pittman (20th century)
