The Pixel 8 Pro’s mystery sensor is… a temperature sensor?

Where does this "FLIR" meme come from for "IR camera" or "thermal-imaging camera"?

The thing that makes FLIR forward-looking is the direction it's pointed in when it's bolted to a plane or a car. On a phone, it's just IR. (I mean, I suppose you could use the phone's accelerometer to detect which direction the phone is pointed in and only enable the camera when it's pointing forward, but it seems an odd feature to want.)

The military use of IR cameras as "Forward-Looking Infra-Red" (FLIR) was the one of the first major applications for IR cameras and was widely known even to the more interested parts of the general public, so in the late '70s a company aiming to develop lower cost IR cameras called itself FLIR to benefit from the association with military "Forward-Looking Infra-Red" (also because their first target customer was the military).

Later, IR cameras made by FLIR ended up in a wide range in commercial products such as handheld IR thermometers and, eventually, phones. So the name "FLIR" stuck as name for all kinds of commercial IR cameras, not because of FLIR the military application but as reference to FLIR the manufacturer (similar like "walkman" stuck as term for portable cassette players even though it was a Sony trademark).

You know which direction it measures temperature. And you have a camera pointed in the same direction. If it is a general purpose temperature sensor you can get a nice camera view with a marker showing you where you're measuring at, and could probably also make a nice "afterglow" type UI for a makeshift scan of an area.

A general IR thermometer would be very useful. I'd use it to see the temperature of my coffee brewing water; check proofing temperature when baking; calibrate the oven, fridge and freezer; tweak airflow in the PC and lots of other uses.

The heart rate monitor is invaluable to me when working out.

My mom’s watch woke her up a few weeks ago after it saw her pulse jump to 170.

Try living on the end of the bell curve… 6 months of a cardiologist fretting before throwing up his hands and saying “your heart is in better shape than the rest of you. It’s just your natural resting state to have heart rate of 120bpm”


Biggest problem is you can’t get ct scans without a lot of work - they’re too blurry if your heart is bouncing around like that.

Ahh, thank you. So it's a USA-ism like Xerox for photocopying or Band-Aid for sticking plasters.

Pretty much, although Xerox did in fact invent the electrophotographic photo copier (as Sony invented the high fidelity portable cassette player for use while walking), however FLIR (the company) neither invented IR cameras nor Forward-Looking Infra-Red.

So aspirin is a better comparison (seeing that was a trademarked brand name for Bayer, and they certainly didn't invent acetylsalicylic acid)
