Idea for LMC safety device.

[minnow]

Hi

had an idea for an LMC safety device, it's so simple it's probably already been done, but I couldn't find anything so I thought I'd post it on the off chance it hasn't.

the first of two parts is an inflatable flotation device that can be fired electronically, it should bring the diver to the surface and float him/her face up with head back and airway open so the buddy can do rescue breathing easily if need be.


the second part is a simple countdown timer, all it does is count down X number of seconds, when it reaches zero it prompts the diver to push a button (beep, flashing light, electroshock :t ) and starts a new countdown, this time if the countdown reaches zero before the diver pushes the button it fires the flotation device.
If the diver pushes the button it starts a new count down and then prompts the diver again, rinse and repeat until 30 seconds after the diver has reached the surface.

at it's simplest it could be turned on by the diver when beginning assent, or if one wanted to get technical the device could be tied into a depth meter that would prompt the diver to start the device any time he/she ascends more than X number of meters in Y number of seconds and even change the countdowns to lower values in the part of the dive when LMC is more likely. ideally the diver would be able to customize settings within safe limits?


occurred to me while reading about static training, tap/acknowledge, was thinking that a winch and harness to lift the divers head and shoulders out of the water would be better than a floatation device for static.

epiphany or brainfart?

It's pretty easy to lift somebody's head out of the water without a winch and harness.

thanx for the link Mullins, that vest as is would be perfect for the flotation device, think I'll send them this idea as an upgrade on the FRV and see if they want to patent and develop it, this seems like a great place to get ideas and advice to make it workable first though.

With the FRV if the diver over exerted and had to surface early and had an LMC he/she could be unconscious for far too long before the timer ran down and the vest inflated, if one got up 2 seconds late the vest would fire needlessly.

The tap/respond style of my idea would complement the FRV quite well while ascending though, with a 5 second timer the longest from LMC to inflation would be 10 seconds and it would require periodic responses from the diver after surfacing for 30 seconds.

for the "Button" part I'm thinking a half glove worn on the divers off hand that supports a button between the thumb and forefinger so it could be pushed with the side of the thumb while swimming or gliding, be nice if it could be worn under the glove but I think over the glove could be made to work.

the vest would certainly cause some drag, but surely it wouldn't be as much of a drag as drowning.

The winch and harness occurred to me when reading about divers drowning while practicing static alone, pretty silly I know, lots and lots of silly people out there though, just go on youtube and search spearfishing, I found 22 videos made by solo freedivers in 5 minutes. After that it seemed like a device to protect silly people from themselves long enough for them to gain wisdom might be a good idea.

You'd better delete this thread if you want them to patent it, from the very little I know you can't patent something once it's out in the public domain but I could be wrong

My brainfart would be a freediving watch with a special capsule and needle that gives you an intravenous shot of oxygen if it detects a BO and then you come round by yourself and swim to the surface - warned you it was a brainfart! LOL

I'd love to see the garage of the safety conscious freediver in 10 years' time.

"Here's my Static Training Crane, let me just wheel it aside..... actually can you give me a hand, it's 400kg. Thanks. Now this over here is the Simos Automatic Emboliser, you just clamp it on over your neck before each dive and spring-load the 10cm needle..."

LOL

(actually I was hoping for a name along the lines of Simos Haemo-Injector Tissue Emboliser)

Mullins you are on the right track. I can see a dedicated automatically-piloted, free-diving boat that has just what you said; a harness and a winch. At the slightest hint of a problem (and I do mean slight) the thing tears you off the bottom and the next thing you know you are hanging ten feet off the surface of the sea with your head inside an oxygen dome...That's the prototype. The Beta version does all that but also splashes you back into the sea and drives you into the bottom until it senses a contraction and then it pulls you back up
