I'd put this in public: safety: first aid, but that doesn't exist
I'm sure most of you have seen the Automated External Defibrillators (AEDs) mounted at strategic locations
around large public buildings such as malls and airports. But have you considered how quickly they could be
brought to where they're needed, when seconds count?
Imagine someone is having
a heart attack at an airport. A bystander who is trained in first aid recognizes
what's happening and shouts for someone to bring an AED.
- Worst case: Due to the bystander effect, nobody brings an AED.
- Best case: A good sprinter happens to be standing near an AED station. They grab the AED and run it over to
the heart attack scene, sprinting along the moving walkways. This takes 20 to 30 seconds. (And they are
exhausted from sprinting, so cannot take over CPR.)
- Even better but not workable case: A person with a jetpack happens to be standing near an AED station, and
can fly the AED over. This won't work because jetpacks are not allowed in airports.
Solution: Instead of AED stations scattered around the airport, there are AED launchers. These are giant
slingshot turrets that can aim and shoot a specially packaged AED to anywhere in the airport, or at least near
enough that a bystander can carry it the rest of the way in five seconds.
When someone shouts for an AED, microphones around the airport pick this up and determine the location
(like the gunshot and other sound source locators that we have several ideas for, and are baked). The nearest
launcher aims for this location and awaits a signal to launch. The security guards (not the checkpoint ones,
but the ones who keep the airport grounds secure) get an alert, and check out what's going on using the
security cameras. If there's actually someone having a heart attack, they give the signal to launch the AED.
The AED flies over to the heart attack scene, and deploys a parachute to land safely. The first aider grabs it
and starts using it.
Mature AED technology + mature drone technology. The idea isn't baked, but a better one is. [CraigD, Dec 09 2015]
A serial catapulter ?

||With such a system in place it would not have to be restricted to defibrillators. You might also deploy rolls of toilet paper (often desperately needed in airports), eggs-and-bacon sandwiches and duty-free booze, all (more or less) safely landing with their parachutes gently flapping like apprentice ghosts during a break.
||It would be ironic to have a heart attack and
then be killed by a flying defibrillator
||"Ok, Doc, whatcha got for us ?"
||"Same as the others, sergeant .... blunt force trauma to the cranium. We've bagged the weapon for forensics, but the M.O.'s identical. I think we're looking at a serial catapulter..."
||Why limit this to airports? Just have the every
hospital in the area (which tend to be, except in very
big cities, relatively tall buildings) put a large
catapult on the roof, which delivers the AED to the
door nearest the emergency every time a 911 call
that might be a heart attack comes in.
||Really this brings into sharp focus the utter ridiculousness of the whole jetpack ban.
||Better get the Halfbakery Crime Lab on it (link).
||People tend to have heart attacks at airports because
that's the way airports are. It may be cheaper to just
rehumanize the entire airport experience.
||I had the thought just now that the turret should be equipped with some kind of
directional speaker (LRAD or similar) to warn people along the planned trajectory of the
AED to get out of the way.
||[CraigD], are you really claiming a drone is better than a slingshot turret? Just a few
months ago there was a big airport drone scare, and everyone's been working on ideas to
keep drones away from airports. Though I guess this one would be indoors. But still, what
if someone hacked it to fly outside, as if there was a heart attack victim outside the
entrance doors, and then fly back over the airport and into a plane's engine? I note that
the article implies the drone could be used across a distance of many city blocks, but so
could a slingshot turretjust scale it up (and equip the AED with a steerable parachute).
