Published

The word coma comes from the greek meaning of “deep sleep,” but what exactly does this unconscious state do to your brain?

How Comas Work

“Illnesses that affect the brain and brain injuries can both cause comas. If a person suffers severe head trauma, the impact can cause the brain to move back and forth inside the skull.”

How Active Is the Brain in a Coma?

“When doctors recently tested former Israeli Prime Minister Ariel Sharon brain with a functional MRI, they found “robust” brain activity when he was shown pictures of his family and heard his son’s voice. A stroke and brain hemorrhage left Sharon in a coma seven years ago.”

    I have been in a coma, for about 3 weeks. it was brought on by pnumonia, which claimed all but the size of a quarter-dollar of my lungs. the doctors told my mother there was "a very good chance he will not make it." when i woke, i recognized my big brother almost immediately, but i didnt recognize my mother for a little while. I was able to make a full recovery since.

    Why does the Glasgow scale start at 3? Does it mean a 1 equals death?

    I was in a coma for 5 days after a Rally Car accident where I was sent into a barrel roll(The car was I recognizable except for the drivers compartment, when I saw it I realized how crazy strong Roll Cages are). I remember people talking to me but I could only sorta make out what they were saying. And for some reason I remember just not trying to talk back, and when I woke I remember choking on my oxygen tube and pulling it out.

    Are you kidding me with that ad at the end? That might be the most overt and misplaced ad I've ever seen. This dissuades me from Harry's.

    "…Even in your hospital bed." Commercials and comas, together at last, That was a poor decision, so long Harry's. You're an idiot company or you let yourself get put in an idiotic place. Why are you selling razors to comas?

    My name is Mason. I was in a coma for years. Woke up with a stupid beard and my nurse Kelly saved my life. She was smoking hot. I left in her mustang GT and recovered from my coma at her house. We humped.. Found my killers and I took Senator Trent, to the blood bank!

    my brother was hit by a car going 70 mph knocked over a 100 feet and was hit by another car coming the other direction and shattered the windsheild with the top of his head and was thrown onto concrete. the paramedics were astonished he was even alive to transport. He was in a coma for a month, They really didn't give us any hope. told us to prepare that he wouldn't make it. but he did he awoke had to learn everything all over again. eat, walk, talk, write, etc…. even his reflexes were impaired at first, but today he has pretty much recovered to meet and talk to him you would not know that it had happened. other than a change personality before he was what I would call a loner. but today it very much a people person , the more the better.

    I suffered necrotizing faciitis throughout my torso and was comatose for about a week. On and off I was vaguely aware of what was going on around me, but completely misinterpreted events. During a thunderstorm I thought pirates were crashing through the windows. All the while I was "asleep" , I was having amazing adventures; I didn't want to wake up. I've tried recording these dreams but what I write is so flat compared to the experience. Has anyone else experienced something similar?

    One of my best friends, fell off the school rooftop and was in a coma for 3 days and survived. What’s more, is her best friend (my crush) fell off the school roof in the same place, was in a coma for 3 months and survived. It’s weird how 2 best friends both fell from the same place and survived, isn’t it?

    I was in a coma for 3 days and it's one of the most interesting experiences in my life but I wouldn't necessarily recommend it. It's like everything, I guess….there are both pros and cons.

    Hi, my name is Tara Flynn, & im Irish, in January 2008, i was rolled over by a 60000 snowplough, in Mammoth Lakes-California. i was fine initially after being hit, but a few hours later, i collapsed into a 9 month coma , im fully (nearly) fully better now, i lost all speech /memory & had to be incubated for a some months. however im a very active person, & am more or less perfect again, however the truck driver was doing something totally illegal- he was driving along with his front loader raised, obscuring his vision. my Mammoth trip was the most awesome thing in the world to me, its just a pity that my accident happened to me when i was only 22 years old. however im definitely planning a return visit this winter to Magic Mammoth!

    From what I think, coma is like a long sleep, when you wake up from a coma, it is as if you slept a normal sleep. You didn't feel the time pass by.

Aerial Rescue Passenger Drone – Cormorant UAV

Published

on

By



Music: The Wolf and the River by Dhruva Aliman Spotify – …The Cormorant is a compact, unmanned, single-engine, VTOL (Vertical Take Off and Landing) aircraft. Internal lift rotors enable the Cormorant to fly inside obstructed (e.g. mountainous, wooded, urban) terrain where helicopters are unable to operate. The Cormorant is innovative due to its internal rotors and significant payload capacity that allows for the evacuation of 2 casualties as well as fast and flexible payload reconfiguration for other missions. It is also ideally suited to special robotic operation, for example via Tele-Presence.

Cormorant Target Markets

Cormorant offers much needed capabilities to emergency responders in routine, day-to-day operations as well as in the most challenging situations such as earthquakes and floods. The ability to quickly deliver water, food and medical supplies directly to affected populations—no matter how isolated—will save lives. During nuclear, biological or chemical emergencies Cormorant offers transformative assessment and response capabilities. Day to day multiple mission capability (electric grids, bridge inspection, agricultural spraying, offshore oil platform support to name a few) makes Cormorant a cost effective addition to any commercial helicopter fleet.

In the civil market, Cormorant also offers all of the benefits of combined heavy payload and unlimited access. Whereas small civilian drones such as quadcopters can only provide “eye in the sky” photographic surveillance or, at best, deliver light packages Cormorant can deliver up to 500 kilos of cargo or equipment in both commercial and emergency response scenarios. Outfitted with remotely controlled mechanical arms, it can also perform useful work for a variety of utility and emergency response missions.

Cormorant Capabilities

Cormorant’s internal rotor design and UA’s patented Fancraft™ technologies enable Cormorant to maneuver with unprecedented precision and safety in even the most constricted areas. Its minimal footprint is only slightly larger than that of a a large delivery van.
By removing the human operator from the loop on most missions, Cormorant can eliminate personnel exposure in hazardous environments.
A single Cormorant is capable of ferrying in excess of 500 Kilograms of useful cargo per each 50 Kilometer radius sortie, thereby delivering approximately 6,000 Kilograms over 24 hours; enough to supply up to 3000 people with food, water and other needed supplies.
Total available cargo volume is 2,640 liters (93 ft^3); 1,540 liters of which are internal (770 liters in each of the main cabin compartments) and an additional 1,100 liters available in an optional belly mounted compartment.
Cormorant can hover in place with high precision and operate in harsh weather and winds of up to 40 knots, a significant improvement over existing helicopters.
The addition of externally mounted utility equipment can enhance the vehicle’s robotic functionality.
Cormorant is designed to the most stringent FAA design requirements for Rotorcraft, resulting in an aircraft with very high safety and reliability.
Cormorant can be optionally equipped with a rocket deployed parachute, that will safely lower the complete vehicle and its payload from almost any height in the case of an unlikely malfunction of its engine or lift rotors.
