I've had a nurse insist that I had some hot coffee, just before they took my temperature. They get mad when you tell them it has been almost
40 years since the last time you had any coffee.
ng to distinguish between a localised infection (in the hand or wrist) and a whole body
he latter, but then again I've not been trained to use a mass-screening the rmometer.
You typify the arrogant overspecialized engineer: you don't know a single t hing about different areas of specialization so you think they don't know a nything. The infrared thermometers have been studied in very rigorous medic al application trials for years now, and the results support their effectiv eness in measuring body temperature, especially in regards to detecting fev er, even correlating well with a rectal temperature measurement to within f ractions of a degree (rectal is considered te ultimate). They don't simply point the thermometer at the skin surface, they point it at an area where a n artery is close to the surface.
I'm pretty sure CDC will not be convening a problem solving expertise integration team that includes the likes of you any time soon. Take your pretentious act of applications wisdom to a circus or something...

Could be a hit though...
I would probably favour interior of the mouth, but cheating is always a risk if someone with a fever wants to get past a checkpoint.
A cheap IR imager is probably the least worst option. The people in the imager FOV provide a reference calibration point. Anyone unusually hot or cold would stand out like a sore thumb with the right colour map.
The question is really are they good enough for the job? They might well be if all you want to do is spot people with a fever.
More critically it is well connected to a fresh blood supply and not subject to surface evaporative cooling. Anything that isn't a polished metallic surface is a pretty good black body for thermal band IR.
A FLIR camera pointing at the queue with the white point set to say 39C would probably pick out anyone with a fever reliably enough for further screening. China used this method to contain SARS successfully.
They do cost a few k each but compared to the cost of cleaning up the mess after you let someone in with Ebola it is noise.
Mostly you will catch people with mundane flu symptoms but that might still be better than failing to spot someone carrying active Ebola.
It is worrying that the UK is still not screening arrivals from West Africa despite having a more significant traffic with affected areas.
At least sending NBC trained military medics out to help gives them a sporting chance.
It will catch as many ebola infected as they have found terrorists.
Of course, being a zombie himself, Jan will look like a smurf on the FLIR. ;)

Imaging as a first screen, followed by a proper temperature measurement, would be a lot better than zapping hands with a cheap IR thermometer from three feet away. But that could only catch people who are symptomatic, which the guy in Dallas wasn't.
Our Flir is a good hothead detector.

Yep, I'm sure a US politician can find a friendly company that will make security temperature measuring gadgets for only a few mega bucks each and mandate they be put in every airport in exchange for some campaign funding

I know at least 2 orders of magnitude more than you do about IR thermometry. I actually worked in the industry back when there were only about three main players.
You are just Fred Bloggs, the s.e.d class clown.
And you do a very poor job of it too.
You nailed it! Exactly.
You typify the arrogant overspecialized engineer: you don't know a single thing about different areas of specialization so you think they don't know anything. The infrared thermometers have been studied in very rigorous medical application trials for years now, and the results support their effectiveness in measuring body temperature, especially in regards to detecting fever, even correlating well with a rectal temperature measurement to within fractions of a degree (rectal is considered te ultimate). They don't simply point the thermometer at the skin surface, they point it at an area where an artery is close to the surface.
For you, rectal would be the same as oral, being that your head is up your ass.
Not to detract from the points you are making, but I have looked at a number of different temperature measurement devices and what I have
procedure each day which could be very simple. Sort of like the police do with RADAR guns.

There is another element that removes any modicum of accuracy...
"From three feet away."
Not a good choice, the fresnel device. Such a method would require a much more expensive instrument to be consistently accurate.
The fresnel window family just does not have the accuracy.
Talk about failed "fuzzy" logic.
Hospitals seem to do pretty well with their temperature measurement devices.
From recent experience, they ask a lot of questions and either don't listen to the answer or don't believe whatever you tell them so the whole exercise is pointless.
I get tired of telling them that I've never smoked, drank or used drugs at every visit. I'm sick of being told that I'm not old enough to have health problems and that I'm in great shape.
The current VA 'doctor' recently told me, "You can't have handicap parking, you're only 61 and you might get better some day." I have had trouble walking for 30 years and have a knee that likes to cause me to fall. I've worn out one cane, and have been 100% disabled for seven years now.
I have used at least 53 bottles of insulin, but I am still waiting for sharps containers for the lancets and syringes.
Back in the shoe-bomber reaction days, I was once hand-wanded (metal detector) by an obviously untrained TSA agent. He simply could not understand why his wand kept alerting on my tennis shoes.
I tried to explain that perhaps he should not sit his subjects next to the metal furniture at the checkpoint.
He x-rayed my shoes (twice), and then said I was free to go. Next victim, please....
I expect about the same level of incompetence with any gadget you hand a TSA agent. Well, perhaps not a kazoo?
