For the first time, the Workhorse SureFly Octopter was introduced at the Paris Air Show last June, though only in the “ground” version. Just the other day, he will make his first test flight after receiving the certificate of airworthiness of the US Federal Aviation Administration (FAA). And the next week, January 8, he will attend the annual CES exhibition in Las Vegas.
It is assumed that during the exhibition workhorse will be free to transport visitors CES. The Octocopter is equipped with four working screws on spaced racks rotating in opposite directions. At the first stage SureFly will be managed by the pilot, and in the future an unmanned version will be developed.
Workhorse, unlike its competitors, air taxi Volokopter , Ehang , Autonomous Passenger Drone, flying exclusively on electric traction, is equipped with a hybrid power plant “electric motor / DVS”, which provides a flight for a distance of up to 112 km with a cargo of up to 180 kg.
Workhorse has already received the FAA airworthiness certificate, which allows it to begin test flights in Nevada. The management of the company hopes that finally the FAO okto-copter will give its final approval at the end of 2019.
The Minister of Communications of Venezuela, Jorge Rodriguez, voiced the desire of the authorities of the country to launch a new type of crypto currency. It will be called “petro” and will be provided with natural resources, first of all – with crude oil. As a “bank”, the oil producing region of Ayacucho will act, where 5.342 billion barrels of certified oil are concentrated.
Venezuela is also ready to support its crypto currency with gas, gold and diamonds, but on very modest, cautious scales. At the first stage petro will go into circulation in the equivalent of 5.3 billion barrels, whose collateral in cash equivalent is 267 billion dollars. According to Rodriguez, the miners already “lined up”, but no details.
Crypto currency, which is backed by real assets, unlike the purely virtual bitcoin and its counterparts, can become an unexpectedly attractive tool for financiers and investors. The world is tired of the dominance of petrodollars and conflicting prices for strategic resources, plus big players are also afraid of inflating new speculative bubbles. Venezuela offers a kind of golden mean – a convenient for transactions crypto currency, which has tangible value in the form of billions of barrels of oil.
Analysts say that the risks of such a step are also great, but the Maduro government is in such a situation when such adventures are extremely appropriate. The country can not get out of the severe financial crisis in any way, while its oil-extracting sector is systematically being picked up by Russia, China and the United States. To slow down this process, to involve in petro numerous private investments and to keep control over natural resources – this is the task that the authors of the new crypto currency set themselves.
Alicante University has developed a technology for travelers and tourists, which allows you to turn a smartphone into a kind of emergency lighthouse. To do this, you need an accessory in the form of a small antenna and an application. The highlight of the novelty is that it works on the basis of Wi-Fi and is designed for use outside the coverage areas of cellular communications.
The principle of operation is simple: if a person is in trouble and he does not have a stable connection, he turns on the application and it starts sending a message via Wi-Fi periodically with a call for help. In the message you can specify that you are injured or lost, add your GPS coordinates, and thanks to the portable antenna the signal is received a few kilometers away. Anyone who has a regular smartphone with Wi-Fi support, will be able to take such a signal and come to the rescue.
The developers say that there are no systems in the world that use Wi-Fi for geolocation in this way. There are devices that can send a working mobile phone to calculate its position using the triangulation method. But there is such an installation of $ 80,000 and mounted on transport. Here – the simplest accessories at no more than $ 700 per set.
The beacon for the smartphone has already been tested by specialists of the Spanish Coast Guard, mine rescue service and military seamen.
In 2012, developer Zack Dennis introduced the concept keyboard for touch screens, which uses the minimum number of data entry points. Now ASETNIOP is available as an application for iOS and Android, but so far only for tablets – adapting to other formats of gadgets is not far off.
On the virtual keyboard ASETNIOP only 10 keys, 4 with letters for the fingers of the right and left hands, and thumbs rest on the space and Shift buttons. When the user starts entering text, the system on the fly recognizes a combination of symbols, searches for analogues in the dictionary of the most common words and reassigns the keys so that it remains to poke in the desired syllable and end the word. It is very similar to the standard autocorrect, but the implementation of ASETNIOP is incomparably more flexible and friendly.
The system can and should be customized for its own printing style, in order to achieve an ideal prediction of the user’s actions. In the keyboard ASETNIOP there are special stenographic combinations of symbols, auto correction and templates for phrases and terms. Experienced users, having mastered, can type text at a speed of up to 100 words per minute with a minimum of errors.
The bottleneck of the conceptual virtual keyboard – all algorithms have a rigid binding to the specific features of specific languages of the world. So far, the support of English, German, Spanish, French, Italian, Dutch, Norwegian, Polish, Portuguese, Romanian, Swedish and Turkish has been declared. The cost of the application in the Apple App Store and Google Play is $ 4.99.
In complex multiple bone fractures, special metal implants are used – screws and pins that hold the damaged bone fragments together and ensure their adhesion. However, this process is very slow and painful.
Against this background, a real revolutionary breakthrough was the development of a group of scientists at the University of Sydney, headed by Halali Zreikat. They created a ceramic 3D implant that holds the broken bones together and then turns into a natural bone.
Implant has already been successfully tested in restoring limb fractures in rabbits. In addition, in the near future, the results of testing will be published with similar fractures in sheep. All eight animals recovered successfully.
So, the sheep began to walk on their own the very next day after implant implantation, though in combination with a cast bandage to stabilize the process for four weeks. Three months after the operation, the scientists recorded complete recovery in 25% of the animals, and a year later this figure rose to 88%.
As the bones grow, the implant gradually becomes a bone. As a result, it not only promotes healing, but also forms bone tissue in those places where it was lost as a result of trauma, and where the implant is no longer needed, it dissolves.
