Nicely visual and utilitarian. |

Mightn't the laser also be tweaked to, ah, abbreviate all
items, fingers, persons, etc that get within that circular
line? Asking for a fellow inventor. |
|
| |
2 meters there? Here its a lousy 6 feet. Someone's
gonna die because we didn't convert to the metric
system. |
|
| |
You can't claim you didn't have fair warning about that. Was the Gimli Glider not enough ? |
|
| |
As to the idea, it seems very short on important details, like exactly how the system triggers perimiter defence weaponry. |
|
| |
Is the line 2m in radius, diameter, or circumference ? For situations where both parties wear such a hat, a 1m radius is sufficient. If only one party has a hat, and a 2m radius, the line will indicate the separation at foot level, but due to the tapering profile of humans, the upper body will be significantly closer. |
|
| |
Cedar Park, it's been a long time, you. Great idea, and if you
wear it with your "distance skirt" you will be all the talk of
the runways, perhaps. Missed ya. |
|

The hat isn't a laser for cutting people's limbs off, it only marks a perimeter that people should not enter. With a low power laser and a big battery, it could last for hours. Turn it on when you have to go shopping. It could have some sort of NFC enabled that cuts off the radius when approaching another hat of the same type. |
|
| |
[8th], it could be made with a projection of 1m and 2m increments, and a proximity sensor that turns it on when others approach to save power. |

[RayfordSteele], RIP Mars Climate Orbiter. |
|
| |
We don't want a laser for cutting limbs off; that would be unfeasable, due to the mass and bulk of the unit, and the power supply requirements. |
|
| |
No, what we want is the system to trigger other weaponry. If you insist, it can be a low-lethality system like a "belt" containing taser cartridges able to discharge in a 360 degree arc. |
|
| |
But you have to insist; something lethal will be so much more effective. |
|
| |
And you can put "Died because of Coronavirus" on the paperwork, so that's fine ... |
|
| |
My 11yo is supporting social distancing by taking a lightsabre
toy everywhere with him and twirling it annoyingly. [+] for
the first hat idea I've read in years (probably just because I
haven't been here). |
|
| |
It's very wrong for you to let him wave a toy weapon around like that. It gives completely the wrong idea. |
|
| |
Give him a real sword ... |
|
| |
Wouldn't work so well on black surfaces such as asphalt
parking lots, but indoors should work just fine. [+] |
|
| |
Real swords work quite well both indoors and outdoors, altho outdoors usually gives more space for a good swing. |
|
| |
You might have issues with the projection moving based on head movements - e.g., nodding would distort the front segment to appear much closer to you, at a time when you're likely not looking forward. |
|
| |
Solved with a shoulder or backpack mount which raises the projection device above your head, making it independent of head motion and looking to all appearances like a halo. |
|
| |
Gyro/accelerometer stabilization will fix that; doesn't need to tilt the whole device, just have an angled mirror on a fast servo. |
|
| |
Walking would cause the "ring" to expand and contract; using the laser as both a designator and a rangefinder fixes both issues. |
|
| |
We're still not seeing sufficient intrinsic lethality, though. |
|
| |
//that cuts off the radius when approaching another hat// |
|
| |
Pity light-light interactions aren't more substantial. I would have loved to seen half of a hyperbola light up between people. |
|
| |
Particle beams could do that, but are impractical in a planetary atmosphere. |
|
| |
I'm thinking a giant sombrero would work. |
|
| |
A sombrero seems to have a radius larger than the height of the crown. |
|
| |
Thus a sombrero with a 1.8m internal height, sufficient to completely enclose a typical human, would have a radius of more than 2m at ground level, where the brim would be. |
|
| |
That would meet the requirement. Castors attached to the underside would reduce friction. |
|
| |
Doorways would need a slot cut out 1.5m on each side, at floor level, to allow the brim to pass through, but that's a mere detail. |
|
| |
Mariachi bands might constitute a serious threat to life and property, but that's hardly a new thing. |
