However, even ALPR doesn't show any devices for me:
I'm glad citizens in the EU are more on top of this. I really wish we as USA citizens had access to the same database of GPS coordinates for each Blink, Ring, and Amazon Key device that police do. Does anyone know how/if something like that could be FOIA'd? This seems it would be particularly fruitful if FBI/DHS has a comprehensive dataset for the entire nation.
Though I do worry that they may not "have" the dataset, but rather just have "access" to it via a queryable Amazon/Palantir database/API.

I've panned the map over several parts of the US, and see many ALPRs mapped in OpenStreetMap.
You can also use the 'Wizard' of Overpass turbo, and enter ""surveillance:type"=ALPR around Miami" (or any other city (e.g. your home town), with quotation marks around surveillance:type) and increase the `radius` in the query until you'll find some.
As an example, here are the ALPRs 25km around Miami: https://overpass-turbo.eu/s/2dVP
>> "The "o" stands for "open", "openness", "open source" and is placed where a "TM" symbol (indicating patents, trademarks, protection) would normally reside. Instead openness is the apertus° trademark."
It's also a completely different kind of thing so trademark probably wouldn't come into it even if they had one.
Was about to mention magic earth, but of course someone else has recommended it already. Was talking with a coworker about degoogling and they brought up this. Surprisingly works good enough where I live.
> OpenStreetMap doesn't even seem interested in things like "this street is closed next week Tuesday"
OpenStreetMap data consumers can have much longer update cycles than "next week", so it makes sense to have such information outside of the map data if you are implementing a router.
As an avid mapper (and liking to go on dinner-dates with my wife) I absolutely love this.
Very slick and quick search, congratulations!
Do you also parse the `opening_hours` tag to filter for currently open restaurants?

The low energy you desire might not be high enough to penetrate the object you want to image, either a weld to inspect, the blacksmiths bespoke object or the human.
For imaging human tissue you want high energy for less radiation dose in the patient. That’s why x-rays are filtered by some mm of aluminum before imaging a patient. These filtered lower energy photons would be absorbed in the patient anyways.
1. Perhaps variable power with unintended backscatter emissions detection would be useful to make it safer and more robust.
2. With more sensitive sensors, the imaging power needed can be reduced. This has been the trend in dental X-ray machines. (Orders of magnitude more power were used in developed film-style apparatus.)
