What will happen when astronauts walk in space

　　Last month, astronauts on the international space station completed a spacewalk to repair purposes. Though there are strict planning, but outside the space station is extremely dangerous, because the walking process may be wrong. So, when astronauts in space have to pay attention to what issues?

　　1. drowning in space

　　Space suit is like a small personal spacecraft, and when it has failed. In 2013, Italy Luca Parmitano spacewalk by astronauts when they found him in the helmet began to ship water, because of spacesuit problems with ventilation systems, water in the helmet over his eyes and ears and blocked his nose.

　　In the case of drowning, he had to stop the spacewalk. In fact, he was not the first astronaut spacesuit failure problems encountered. Back in 2001, Canada astronaut Chris Hadfield found his left eye began to Sting, and began to cry, and then he went blind in space. Because of concerns about spacesuit leak of toxic gas, he in the suit had to be released to ventilate toxic gas.

　　2. fly away

　　Although there were no astronauts lost in space, but Chris Hadfield said this was the thing he most worried about. Any spacewalks astronauts need to be strapped to a 26-meter-long steel cable. Spacewalk the astronauts usually together with their partners, Eva tied together before. Marcelo Burlon iPhone plus

　　Although this is a small probability events, but if astronauts had really gone do? Chris Hadfield said: "we can be steered by Jet Pack to fly back. "

　　3. boiling blood

　　Spacesuit will protect astronauts during spacewalk will not be under vacuum conditions of tearing, puncture and other fatal injury. In a vacuum, the human body expands to about twice normal size. United States Air Force pilot Joseph Kittinger in 1960 this is discovered in skydiving, and when his glove in the parachute off, his hand was swollen scary, back on the ground and then back to normal.

　　If there is damage suits, then most likely cause because hypoxia after 15 seconds and died. If there is no space suits provided by the supercharged environment, human body fluids will be a boiling situation because of the expansion of gases in the body, even if oxygen is not "kill" the astronaut, and other factors.

　　4. tired dogs

　　Last October, the United States during a spacewalk by astronauts Scott Kelly and Kjell Lindgren, took 7 hours to complete the mechanical arm, control cables and accessories, and more.

　　Space walk needed for such a long time, partly because of 160 kilograms of spacesuits are weightless in space, but it is still very, very cumbersome. Astronauts are not simply a task in one location, for example, when they need to twist the wrench when their body will turn to, that is, to finish the work they need to spend more effort.

　　In addition, the astronauts also need strength to keep my body stable. So, in conditions of weightlessness, a seemingly simple spacewalk mission really will let astronauts tired dogs.

　　5. x-factor

　　In 1965, Soviet Cosmonaut Alexey Leonov conducted only a 12-minute spacewalk, even so, he almost died in the space. Because the engineers did not take into account the space suit in zero-pressure conditions can make the expansion issue, Alexey Leonov nearly no way back to the cabin. Later in the same year, United States astronaut Ed White completed a narrow escape, because his spacesuit is a problem.

　　In the process of conquering space, astronauts encountered numerous unknown factors, Chris Hadfield said: "astronauts have to do is prepare for problems with all the minute details in advance, even if you do meet the have no fear. "

Save a drop of blood new system to diagnose strokes just 10 minutes

　　About 795,000 Americans of stroke patients every year, a rapid response diagnostic tests will soon be able to come in handy. From the Institute for animal health, Cornell University scientists have created a stroke diagnosis system, which means faster diagnosis than current tests. Paul Frank iPad Mini Case Paul Frank iPad Mini Case

　　Researchers say, just a drop of blood, in less than 10 minutes the system will be able to diagnose patients with stroke within the time, and now rely on CT scan, blood tests and other methods can take up to 4 hours to get results. If counted by minutes, patients spend $ 34 billion a year, this new device can completely transform a patient's life.

　　It is obvious that modern medical trend is smaller, simpler and faster. The study's lead author Roy Cohen said: "three-fourths of stroke in patients with ischemic stroke (cerebral blood vessels blockage), in this case, time is of the essence. Even with a very good drug, also take 3-4 hours to take effect. Until the symptom was found, taken to the hospital, lying in the emergency room, patients simply do not have much time to absorb drugs. "

　　He said that more rapid diagnosis could reduce the number of patients with ischemic stroke, because the disease is one of the leading cause of long-term disability. In the United States, every 4 minutes, 1 person dies from a stroke. Even survive, can also occur in patients with chronic fatigue and vision problems, and so on.

　　When a stroke occurs when this new diagnostic system to detect biomarkers in the blood, and these molecules are converted into light. When these biological markers in the patient's blood is concentrated in time, just need to test whether the light is able to diagnose a stroke.

　　In recent years, micro received a lot of advances in medicine, such as AIDS and cancer the finger test, and so on, but the accuracy of these provided there is still mistrust. Recently, the Silicon Valley lab promised him a drop of blood in diagnosis of a myriad of health problems within a few hours, results it was found that its functions have been exaggerated, it also makes the rapid diagnostic test accuracy is more and more doubt.

　　A new study also showed that the content of each drop of blood can be very different, this results is more doubt whether this new model really so magical. Studies have found that only an adult taking more than 5 times or more in order to achieve accurate results.

　　Carried out by researchers at Cornell University study shows that this technique can be used to test humans and animals of the deep state, from heart disease to traumatic brain injury, and so on. Roy Cohen is now looking for strong evidence proved the critics wrong.

　　It is understood that the researchers plan to a private company to help develop clinical trials for stroke detection technology, and finally apply it to hospitals.

Smart bracelet when jewelry 30 Crystal you go blind

　　Health became urban men and women care about most topics, wearable device also inject a lot of energy into the market in recent years, Polar company has introduced smart like Polar Loop bracelet. Not long ago, Polar introduced the second generation of Loop Loop 2.

https://www.youtube.com/watch?v=Y0KoC5Xf0Co

　　 Loop 2 's basic function is similar to smart bracelet now, so what makes it stand out? In recent days, Polar and Swarovski teamed up, they create a Polar Loop Crystal.

　　Yes, Polar Loop Crystal main target population no doubt GALs, but if you are a boy who is interested in these shiny things, you also have the option to purchase it. The smart bracelet decorated with 30 Swarovski crystals and has a polished stainless steel plates, white, soft silicone textured strap can be customised. 85 unique LED light on the screen, you can allow users to transform views.

　　Certainly, except bright blind has we of eyes zhiwai, Polar Loop Crystal other of function and Polar Loop 2 almost, you also can through it received notification or information, it also also will reminded those long sat of user are, you the up go walking moving has, it also also not has built-in of heart rate sensor, if you wants to monitoring heart rate, you also have addition purchase a H7 heart rate monitoring chest with.

　　We have mentioned before, maybe in the future, women will have a crush on these smart jewelry, pure jewelry has been unable to meet their desires, and smart devices, they may not see at the time. Introduction of the smart jewelry there are many problems to be solved, but Swarovski route, perhaps giving some inspiration for many technology companies, after all, the tie between Swarovski and smart device has been very deep and have a very close relationship.

Intel IDF in 2015 rockchip how brushes the sense of presence

Today is the first day of Intel IDF 2015 Technology Summit, this time last year and Intel jointly announced the rockchip enter the mobile market today is once again standing next to Intel.

But this time, two of the messages are clearly more interesting to some-at the press conference, rockchip CEO Li and Intel CEO speech together with odd, declared SoFIA 3G-R of communications chips for bilateral cooperation will be formally listed on the official mass production worldwide.

SoFIA 3G-R, we want to know what?

In this year's MWC Festival, Intel released the location entry level mobile phones and Tablet Atom Processor X3 series, the series combines the X86 kernel, and ARM Mali GPU integrated baseband modem, including Intel Atom x3-C3130 (3G), Intel Atom x3-C3230RK (3G) and the Intel Atom x3-C3440 (LTE) of three products, are made of 28nm process. Moschino case for iPhone 6

Quad-core mobile chip in first half of x3-C3230RK--, SoFIA 3G-R (C3230RK), is a by Intel and rockchip developed a 64-bit Quad-core 3G chip, but also speak to the world's first tablet and Smartphone quad-core 64-bit 3G integrated communications platform. And you know, by two chip companies to jointly develop a chip, which is rare in the history of the entire mobile phone chip design.

SoFIA 3G-R CPU architecture and Modem are Intel's technology, but it is in areas such as multimedia, display, memory, support, but continued the rockchip Tablet chip advantage. Compared to similar products, SoFIA 3G-R has the following advantages:

SoFIA 3G-R (C3230RK) uses a 64-bit Quad-core Atom architecture, is the most powerful quad-core 3G chip;

Quad-Core GPU for Mali450, run up to 22000 or more;

SoFIA 3G-R (C3230RK) integrates rockchip advantages in multimedia, video support on the latter H.265 hardware decoding technology developed and supported 1080P FHD;

Using Intel 3G Modem, stability and global recognition over other competing products;

Supports up to 13 million pixel camera

Support LPDDR2/3, DDR3, DDR3L items available on the mainstream memory storage can also support the eMMC and NAND FLASH.

Package comes pre-loaded with the latest Android5.1 System.

It is learnt that the Terminal in April, carrying the chip production.

But worth a mention of is, this paragraph chip although is common development, but for Intel and Swiss core micro-for, its regardless of is platform itself also is platform design are has great of different sex, simple for is common into market, but will respectively using itself and customer of different resources and advantage, oriented their of cooperation partners to provides different of service, so both Zhijian also not exists directly competition. Moschino iPhone Cases

For Intel, this is the span of counteroffensive

SoFIA 3G-R in less than six months time to meet production targets, which is interpreted as a rockchip rely on excellent promotion and execution, break down barriers between different cultures and levels of achieved results. In practice, however, cannot ignore is the increasingly great pressure of market, to a large extent the cooperation between more than a glimmer of hatred.

For Intel, in particular, its sense of their presence in the mobile market than Qualcomm and mediatek, more importantly left the remaining time is not much, rockchip together and occupy the bulk of goals aimed first at mediatek 3G market, Intel and then attack the first step in the mobile market.

In comparison, entry 3G market on the one hand because of the domestic and foreign markets are of great potential, coupled with competition in the market is not so intense, so landing is suitable for Intel. In addition, it is reported that cooperation between LTE chip will be coming soon.

For the rockchip together on Intel is a big step

Although the ideal is not as Intel hoped to pick drop Qualcomm chips, into a single giant so vast, but for the rockchip, transition from the implementation of the current strategy, become a based on smart phones, tablets, wearable device of mobile chip design company, but is not simple.

And has has Intel of power zhihou, while in by Qualcomm and mediatek step step press Xia of flat market in, Swiss core micro-not faced overweight of pressure, especially consider to in in the end market has achieved guarantees of mediatek, in by from high-end main of Qualcomm pressure Shi, more of is will will this unit pressure diffusion to Swiss core micro-, manufacturers, and now has has Intel of joined, at least Swiss core micro-in performance Shang not has too big concerns.

On the, as Shenzhen digital industry of scenes hero, in past ten years in Swiss core micro-has been participation promoted with Shenzhen digital industry a step a step go to today, can although its has with rich of network connection and graphics processing aspects technology, and industry resources and solid of local market experience, but is missing March communications market essential of a items technology--base with, and Intel Zhijian of cooperation, is can makes its in one fell swoop jumped out of has this shackles.

Rockchip said, will be the first to tap its resources accumulated in the Tablet, on the one hand these manufacturers for power phone business as early as the idea, on the prior experience of cooperation, as well as the common goal will be more efficient to promote concrete cooperation in the market.

Rockchip frequently appeared, 2015 or very well

It is reported that SoFIA 3G-R will this year not only rockchip is a top priority, a WiFi product line but also to maintain sustainable development and, in addition, rockchip can access to Internet and vehicle markets.

And it is not difficult to find, in 2015, while just over a quarter as a whole, but as China's leading chip manufacturers rockchip has been frequently, including late last month joined Google ASUS, Hisense, Haier, and several brand new Chromebook released, all using the rockchip RK3288-C processor, which was homemade chips into the PC market for the first time.

Qian has Google, and ARM, again plus now of Intel, currently has has three home market Super billions of dollars of international giant and Swiss core micro-expand has strategy cooperation and launched has products, this means with long-term was Europe developed monopoly of chip field, in to Swiss core micro-for representative of domestic chip manufacturers of efforts Xia, domestic has has has increasingly strong of competition capacity, and harvest has increasingly more of recognized.

The Ministry released in 2015 industrial basis, specialized in the implementation of the programme of action, also pointed out that through the efforts of about 10 years, and strive to achieve the core foundation of 70% parts (components), key-based material independence guaranteed, some reached the international advanced level. It as a hub for smart devices the brain of high-end chips are named key, so we have reason to believe that, through 2015, as represented by the rockchip domestic chip manufacturers will have great performance.

Stools made of balloons but it was not bad it also shouldn t blow it

From Korea designer Seungjin Yang's idea, brought him some stools made of balloons, but you both not bad it also shouldn't blow it! FOSSIL iPhone 5 FOSSIL iPhone 5 Case

No, no, no matter how hard you blow, it will not explode--because, looked like a balloon that is actually black! Designer these stools are made with epoxy resin material and, if possible, to make them look like balloons, to add interest do you think designers do--? Have to admit, it really is like a balloon.

Inspiration for this design, is said to be the designer's childhood life experience – at that time, young home designers, working in a sausage factory, daily task is to blow pig intestines ... ... Well, what I tell tall tales, Korea people, should not be blown pig intestines, is more likely to be blowing dog colon –-

https://www.youtube.com/watch?v=YS_P-7iGtBc

Anyway, we recommend a white balloon ... ... Because, it is like most of the large intestine, HA HA.

United States Colorado woman installed artificial eyes success

　　Believe many small partners in recent years on television or on the network should have seen a lot of similar news: a child die and give their corneas and other organs, the two patients to see the light. For such a thing, I have to say, must be the first thing to do is for those people who in the last moments of life to contribute their value sent blessing, wishing them a world without pain.

　　But for many of those still alive, they will probably bear feel light pain. After all, even if you have enough money to do the surgery, but if no suitable corneas for use, any effort is in vain. And now, maybe a lot of blind people have the opportunity to change this situation, because in the near future, United States, Colorado, a woman received a transplant of artificial Bionic eyes. Hello Kitty iPhone plus case

　　According to the foreign media on December 11, said the woman was at the University of Colorado hospital UCHealth centers for eye surgery in an operation that lasted for 5 hours. Surgery woman named Carley, she suffers from Retinitis Pigmentosa disease, the disease made her dying retinal cells, eventually leading to complete blindness.

　　The Bionic eye is made up of a built-in microchip and micro-camera, camera video of the current situation, and to pass on the video chip, and chip orders, by stimulating the nerves and send Visual information to her brain, which could give her a second chance for sight.

　　Is responsible for the practice of Ophthalmology, Dr Naresh Mandava said: this technique is not very perfect, but requires a lot of time, it uploads the image is relatively vague, can only help patients see, and not very clear. Meanwhile, its present form seem particularly attractive. Of course, these issues will be the focus of future work. They will try to get more people back to get brighter.
