<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;">Today's flying cars have two engines - either of which if failed - could result in a crash. One interesting feature of quadrocopter design is that if one of the four quadrocopters failed - the other three can still land properly. But why stop with just four engines? Quadrocopters have been coordinated effectively to fly in coordinated swarms of twenty - successfully navigating obstacles and between each other in ways that exceed human ability without training.</span></div>

Consider that if we just used the air space fifty feet up in a planar fashion, the traffic could split between the ground and the sky and traffic would be half. Use the layer 25 feet above that and the traffic is now 1/3rd as dense. Truly, the sky is the limit.</span></div>

<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;">Multi-trauma patient transport might never be the same. Multicopters could be carried with ambulances or reach scenes helicopters cannot. Ambulances could stabilize patients in the field, place them on stretchers mounted on multicopters. Patients could be lifted from the scene and taken to the nearest hospital - avoiding roads - and taking the most direct route. One can imagine seeing patient after patient being lifted from the scene simultaneously - while other multicopters return for additional people. A two man version could enable a single paramedic to care for the patient while in transit. </span></div>

Like other NFC stickers, TecTiles rely on near-field communication technology to communicate a set of instructions.</p><p>The stickers, which Samsung will sell in packs of five at each of the Big Four carriers' retail locations ($14.99), correspond to a free <a href="http://www.cnet.com/android-atlas/">Android</a> app that is responsible for the actual programming. With them, you'll be able to set a TecTile to set your alarm, check into a social network, auto-compose a text to a particular recipient, turn the phone to driving mode, and so on.</p><p>In some cases, you can mix and match tasks within the same category, so that tapping the NFC-capable phone to the sticker you've affixed to your bedside lamp turns on night mode and the alarm, and tapping it again toggles them off. Likewise, a TecTile on your <a href="http://reviews.cnet.com/car-tech/">car</a> dash may toggle car mode while also engaging Bluetooth for calls.</p><p>You can reprogram the stickers to your heart's content, and the free app will work with the Samsung Galaxy S III, <a href="http://reviews.cnet.com/samsung-galaxy-nexus-sprint/">Galaxy Nexus</a>, <a href="http://reviews.cnet.com/smartphones/samsung-galaxy-s-ii/4505-6452_7-35003061.html">Galaxy S II</a>, <a href="http://reviews.cnet.com/smartphones/samsung-galaxy-s-blaze/4505-6452_7-35118613.html">Galaxy S Blaze 4G</a>, and <a href="http://reviews.cnet.com/smartphones/samsung-nexus-s-at/4505-6452_7-34431171.html">Nexus S</a>.</p><p>You'll also be able to download and use the app and TecTiles on non-Samsung phones, so long as they're NFC-enabled, like the <a href="http://reviews.cnet.com/smartphones/htc-one-x-gray/4505-6452_7-35150644.html">HTC One X</a>.</p><p>With TecTiles, you'll also be able to display a message of your choice on someone else's screen, place a call, launch an app, open a URL, check into Facebook, automatically "like" something on Facebook, follow a Twitter contact, and connect on Linked In, among a few other tasks.</p><p> </p></div> <br> <div style="margin: 0px 2px; padding-top: 1px; background-color: #c3d9ff; font-size: 1px !important; line-height: 0px !important;"> </div> <div style="margin: 0px 1px; padding-top: 1px; background-color: #c3d9ff; font-size: 1px !important; line-height: 0px !important;"> </div> <div style="padding: 4px; background-color: #c3d9ff;"><h3 style="margin:0px 3px;font-family:sans-serif">Things you can do from here:</h3> <ul style="font-family:sans-serif"><li><a href="http://www.google.com/reader/view/feed%2Fhttp%3A%2F%2Fwww.kurzweilai.net%2Fnews%2Frss%2F?source=email">Subscribe to KurzweilAI » News</a> using <b>Google Reader</b></li> <li><a href="http://www.google.com/reader/?source=email">Get started using Google Reader</a> to easily keep up with <b>all your favorite sites</b></li></ul></div> <div style="margin: 0px 1px; padding-top: 1px; background-color: #c3d9ff; font-size: 1px !important; line-height: 0px !important;"> </div> <div style="margin: 0px 2px; padding-top: 1px; background-color: #c3d9ff; font-size: 1px !important; line-height: 0px !important;"> </div>Unknownnoreply@blogger.com3tag:blogger.com,1999:blog-7177070356497060288.post-34265346049739747222012-05-21T05:00:00.001-07:002012-05-21T05:00:36.536-07:00While looking for evidence around the doubling time of neural implants for quadriplegics....<div>....I found reports on the total worldwide count of cochlear implants.</div><div><br></div><div>The trend for cochlear implants worldwide is not only exponentially increasing - but accelerating.

MEG also might be useful in brain-computer interfaces.</p><p>MEG currently relies on SQUID arrays mounted in heavy flasks containing cryogenic coolants because SQUIDs work best at 4 degrees above absolute zero, or minus 269 degrees Celsius.</p><p>In contrast, the chip-scale NIST sensor is about the size of a sugar cube and operates at room temperature, so it might enable lightweight and flexible MEG helmets.

Researchers from UCLA's School of Engineering and Applied Science and the School of Medicine have designed a system that can harness distant groups of people to analyze pathology images for signs of disease. They tested the ability of non-professionals to quickly learn to detect malaria when looking at images of red blood cells and have shown that if necessary, with a bit of help from online crowds, large groups of people can potentially be screened for the disease.<br />
The system they built relies on video gaming to attract people to do the visual tasks necessary to spot malaria. The study subjects, mostly untrained newbie undergrads, showed a spotting ability that was within 1.25 percent of medical professionals.<br />

It feels like the Holy Grail of spinal medicine. Each announcement seems to put us just in reach. Yet when I read them, I cannot help but feel encouraged and sad that Christopher Reeves will not be around to benefit from them.<br />

Brain Implants Help Paralyzed Monkeys Get a Grip</h1>
<div>
sciencehabit writes "Spinal cord injuries cause paralysis because they sever crucial communication links between the brain and the muscles that move limbs. A new study with monkeys demonstrates a way to re-establish those connections. By implanting electrodes in a movement control center in the brain and wiring them up to electrodes attached to muscles in the arm, researchers restored movement to monkeys with a temporarily paralyzed hand. The work is the latest promising development in the burgeoning field of neuroprosthetics."<br />

One can experience this driving through the dense fog in Abu Dhabi desert every night. How long until we can harvest this moisture and reclaim our deserts?</div><div><h1>Wind Turbine Extracts Water From Air</h1><div>An anonymous reader writes "Getting access to enough water to drink in a desert environment is a pretty tough proposition, but Eole Water may have solved the problem. It has created a wind turbine that can extract up to 1,000 liters of water per day from the air. All it requires is a 15mph wind to generate the 30kW's of power required for the process to happen. The end result is a tank full of purified water ready to drink at the base of each turbine."<p></p><p><a href="http://hardware.slashdot.org/story/12/04/18/196243/wind-turbine-extracts-water-from-air?utm_source=rss1.0moreanon&utm_medium=feed">Read more of this story</a> at Slashdot.</p></div><hr><p>Original Page: <a href="http://rss.slashdot.org/~r/Slashdot/slashdot/~3/X_tbK6u0GQQ/wind-turbine-extracts-water-from-air">http://rss.slashdot.org/~r/Slashdot/slashdot/~3/X_tbK6u0GQQ/wind-turbine-extracts-water-from-air</a></p></div>Unknownnoreply@blogger.com1
