<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Anura is a new generation of a pocket-able drone which just fits in your pocket and when you have an urge to fly it you can do it by simply unfolding quad rotors of the drone like an army swiss knife.Drone is a size of an iphone6 and it fits quit easily in any pocket. Anura is also quit cheap considering other drones which are available in the market like the parrot AR drones which will cost you around 500 US dollars. Cost of Anura is 200 dollars which will be available through a kickstarter campaign, which will start in mid October.</span></div>

<div style="text-align: justify;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;"> This little drone do not need any of the dedicated controller to control it, you can do it simply by your smart phone. The drone is compatible with any of the IOS and android devices over wifi and along with that it has a mico-camera that provide you a live feed on your smart phone and it can click pictures as well.Anura has a range of about 80ft (25m) <span style="background-color: white; color: #333333; line-height: 22px;">with a flight time of around 10 minutes per charge, while top speed is claimed to be 25 mph (40 km/h).</span>  The team of anura are also hoping to incoporate saome aded flight functionality if the funding of the drones reaches there goal, following are flight functionality which will be added, <span style="background-color: white; color: #333333; line-height: 22px;">such as phone tracking, auto takeoff, auto landing and a return home function. In my opinion this quadcopter drones is for those people who love to fly rc toys or drones and it will be a good add-on to there collection. Please take a look at this video which explains all the functionality and features of this anura quad-copter drone.</span></span></div>

Students develop drone to locate survivors via their mobile phones

<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><img alt="Jonathan Cheseaux with the drone that uses a Wi-Fi antenna to locate mobile phones (Photo:..." height="358" src="http://images.gizmag.com/hero/drone-phone-location.jpg" width="640" /></span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">These days, most people are inseparable from their mobile phone, with the device being one of the essentials along with keys and cash or cards that people don't leave home without. A project at EPFL's Mobile Communications Laboratory is looking to take advantage of this fact by developing a drone that would help rescuers search for victims of natural disasters by locating their phones.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">When a mobile phone's Wi-Fi is switched on, the device emits data packets at regular intervals. The strength of these signals can vary depending on the surrounding terrain, the weather, interference, or if the device is buried under a layer of rubble as the result of an earthquake or other natural disaster.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Taken in isolation, with all these variables it isn't possible to accurately calculate the location of the device that is emitting the signals. However, by capturing the signals from several different points it becomes possible to calculate the device's approximate location. This is where the drone comes in.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Using a Wi-Fi antenna attached to what appears to be a senseFly eBee UAV, it is possible to capture the signal as the drone flies between different points to better map the location of the device and, hopefully, the person it belongs to.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Cheseaux, who worked on the project for his master's degree, says that automatically eliminating weaker signals from the calculations has helped to improve the accuracy of the system, which has been able to locate mobile phones on the EPFL campus with a high degree of accuracy.</span></div>
<div class="article_img" style="background-color: white; color: #333333; height: 302px; line-height: 22px; margin: 0px auto 5px; padding: 0px; width: 530px;">

<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">"In the best tests we have performed, the place indicated was within 10 m (33 ft)," says Cheseaux, who, being an amateur mountaineer, added, "The drone’s Wi-Fi antenna could be replaced by Avalanche Victim Detectors (DVA) which would enable the rapid and inexpensive deployment of the first avalanche searches."</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The project also involved the development an interface that allows those on the ground to track the aircraft in real time. Detected mobile phones are indicated by colored dots on a computer display, with the drone also tightening its flight around a selected device to indicate its position.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The system can be seen in action in the following video.</span></div>
