Usage
At their peak, about 95 machines were installed in 34 airports. The majority of these were GE's Entry Scan and a few were Smith's Sentinels. According to an article on the 10 October, 2007 in USA Today, the TSA had planned on installing 434 machines; however, due to maintenance problems, they have halted installation and "have no plans to acquire more." The Department of Homeland Security (DHS) has reported involvement with Syagen's MS trace portal machine recently, funding them in 2008 with one unit tested at Orange County Airport shortly afterwards. At some airports, the machines were replaced either by millimeter wave scanners or backscatter X-ray machines.
Among those airports where they were in place included:
- Albany International Airport
- Albuquerque International Sunport (no longer used, replaced by millimeter wave scanner)
- New York (John F. Kennedy International Airport)
- Boston (Logan International Airport)
- Miami International Airport

As well as having been implemented in US airports, there are also Puffer machines at the Statue of Liberty (GE EntryScan3), just before visitors enter the statue itself. This is one example of the many increased security measures taken for popular New York landmarks post September 11, 2001.
The Israeli Border Police use trace portal machines at border crossings into areas under their jurisdiction such as the Allenby Bridge.
Three machines are installed at the security check for the CN Tower in Toronto, Canada.
Five machines are also currently operating at the "Gentilly-2" nuclear plant in Quebec.

Famous quotes containing the word usage:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
