New Smartphone App to Help Locate People in Areas Without Network.

New Smartphone App to Help Locate People in Areas Without Network

Scientists have developed a smartphone app that can be used in emergency situations
 arising due to earthquakes, floods or forest fires, where mobile phone infrastructure is 
often rendered useless.
The system created by researchers at the Universidad de Alicante (UA) in Spain makes
 it possible to locate people who have suffered an accident in remote locations without
 a phone signal and where a speedy rescue is essential to save lives.
"We have designed an application (app) that can be incorporated into any smartphone and
 that, without a signal, emits a Wifi signal which in turn acts as a distress beacon over a
 the distance of several kilometres" said Jose Angel Berna, creator of the technology and
 professor at UA.
This signal contains the location (coordinates) of the person who has suffered the accident
 or disappeared and is using the smartphone emitter, along with a short message that can
 be altered depending on the situation, with examples such as "I am injured," "I am
 disorientated," or "I need help," said Berna.
In order to detect the distress signal, the researchers have also created a light,
 portable receptor device that rescue teams or mountain shelters could use.
This device has a small antenna and connects to the smartphone of the search party.
 When an accident occurs, the victim only has to activate the mobile phone app, which will,
 in turn, emit the distress signal periodically - for hours or even days, even if they are
 unconscious - indicating the coordinates of its location.
During the tests performed on ground and sea, it was confirmed that the device can
 pick up the distress signal of the emitting smartphone up to a distance of two or three 
kilometres, respectively, although it may be possible to increase its reach, researchers said.
"At present, there is no system in the world that uses Wi-fi signals to geo-locate a 
smartphone. There are devices that allow you to detect mobile phone signals from a 
smartphone and pinpoint its location through triangulation, but it costs around
 EUR 80,000 (roughly Rs. 61 lakhs) and requires the use of a helicopter," said Berna.
However, the new system is more economical, "as its receptor has a cost that would
 allow its commercialisation for approximately EUR 600 (roughly Rs. ) is used by a large
 a number of rescue teams," he added.

Bill Gates is Buying Land in Arizona to Build a "Smart City".

Bill Gates is Buying Land in Arizona to Build a "Smart City". The community will integrate technology and high-speed data into its infrastructure. An investment firm run by Bill Gates has put down $80 million to develop a planned community in Arizona. The 25,000 acres of land is about 45 minutes west of Phoenix, in an area called the West Valley. The community, which Gates wants to turn into a "smart city," will be named Belmont. "Belmont will create a forward-thinking community with a communication and infrastructure spine that embraces cutting-edge technology, designed around high-speed digital networks, data centers, new manufacturing technologies and distribution models, autonomous vehicles and autonomous logistics hubs," Belmont Partners, the Arizona real estate investment company involved in the deal, said in a news release. The proposed freeway I-11, which would connect the Belmont area to Las Vegas, makes the land an ideal spot...

Swiss Researchers Built a Robot Fish That Other Fish Will Follow.

Swiss Researchers Built a Robot Fish That Other Fish Will Follow. In associate degree study to examine if animals can react to robotic tries to move with them, Swiss researchers have designed a robotic fish that may with success imitate and mingle with zebrafish."We created a sort of 'secret agent' that may infiltrate these faculties of little fish," says Frank Bonnet of Swiss Federal Institute of Technology in Lausanne (EPFL). EPFL researchers selected the tiny fish thanks to their abrupt bursts of movement. It's troublesome to make an automaton that may integrate into a species like a zebrafish, that have a deeply developed "lateral line network," a sensory network evolved to observe the pattern of water movement. This sense is what permits fish like zebrafish to suddenly modification directions as a gaggle. The scientists thought-about the physical characteristics of zebrafish, such shape, colour and stripe once choosing a species to review. T...

Self-Driving Trucks

Tractor-trailers without a human at the wheel will soon barrel onto highways near you. What will this mean for the nation’s 1.7 million truck drivers? Roman Mugriyev was driving his long-haul 18-wheeler down a two-lane Texas highway when he saw an oncoming car drift into his lane just a few hundred feet ahead. There was a ditch to his right and more oncoming cars to his left, so there was little for him to do but hit his horn and brake. “I could hear the man who taught me to drive telling me what he always said was rule number one: ‘Don’t hurt anybody,’” Mugriyev recalls. But it wasn’t going to work out that way. The errant car collided with the front of Mugriyev’s truck. It shattered his front axle, and he struggled to keep his truck and the wrecked car now fused to it from hitting anyone else as it barreled down the road. After Mugriyev finally came to a stop, he learned that the woman driving the car had been killed in the collision. Could a computer have done bette...
