What mobile phones inside the gyroscope is

Now, when we opened for rabbit testing phone hardware, often found in the sensor bar has a thing called gyro sensors. On this phone is mainly used to test mobile stance, we play games without it, some camera phone image stabilization when using it. Hello Kitty iPhone 5S case

However, this seemingly universal history on a very large, what is it exactly? We take a look at.

One, gyroscope invented

Gyro sensor of the phone now has evolved into a small chip, but when the gyroscope appears, it is a mechanical device.

At present, it is generally considered to be 1850 France physicist Léon Foucault (J.Foucault) in order to study the Earth's rotation, invented the gyroscope. Gyro can be interpreted that era into a high-speed rotating gyro gimbal top, because when the gyro is rotating at high speed stable, people can pass gyroscope orientation in the direction determined attitude, calculation of angular velocity.

Gimbal can guarantee no matter how rotation, gyroscopes fail, gimbal this harks back to censer China thousands of years ago.

Gyros after the invention, the first to be used in navigation (when there is no invention of the airplane), and was later used on the air. As the plane flew in the air, is not the same as ground by macroscopic orientation, and see clearly are extremely dangerous in flight direction, so gyro applied quickly, be central to the flight instruments.

To the second world war, defying manufacturing new weapons in all States, the Germans carried out missile to blow United Kingdom, this is the prototype of the missile. Germany flew to the United Kingdom, the way how to make missiles could fly to, also fell to target?

So, Germans out of inertial guidance systems. Gyroscope inertial guidance systems used to determine the direction and speed test acceleration using accelerometer, and through mathematical calculations, you can calculate the distance and course of missile flight and control attitude, striving to enable missiles fell to where we want to go.

When the second world war, computers, instruments, accuracy was not enough, so Germany missiles a significant margin, wanted to bomb London, results blow everywhere, the British panicked for a while.

However, since then, based on the gyroscope inertial guidance systems are widely used in aerospace, missile there is still this thing today, and with the stimulation of demand, gyroscopes are also evolving.

Second, evolution of gyroscopes

Earliest mechanical gyroscope, which really have a high speed spinning top, and mechanical requirements for high precision, would shake, so precision mechanical gyroscope-based navigation system are not too high.

So people started looking for a better way, progress in physics, develops laser gyroscopes, fiber optic gyroscopes and MEMS gyroscopes (MEMS).

Although these things are also called gyros, but their principles and the traditional mechanical gyroscope is are two different things entirely.

Fog is used sagenake (Sagnac) effect by light transmission characteristics, measurement of optical path difference to calculate the angular velocity of rotation, play the role of gyroscopes, replaced gyroscopes function.

Laser gyroscope angular velocity through an optical path difference calculation, replace gyroscopes.

MEMS gyro is to use Coriolis forces of physics, have a small capacitance changes in internal and measurement, calculate the angular velocity, replaced gyroscopes.

IPhone and Smartphone we might use gyroscopes are MEMS gyroscopes (MEMS).

At present, the traditional mechanical gyroscope is being phased out, is used where there is demand for high precision laser gyroscopes, and universal is MEMS gyroscopes.

Because MEMS gyroscopes (MEMS) belongs to the microelectronics, rapid development, and is getting cheaper, so more and more widely used. Our smartphones to detect dynamic because of the demand, so he used MEMS gyroscopes (MEMS).

Third, the ubiquity of gyroscope

Gyro is the presence of large, but because the MEMS gyroscopes (MEMS) the emergence of low-cost gyro can be used in many fields.

In addition to the familiar other than smart phones, cars also use a lot of MEMS gyroscope in a fancy car, about 25 to 40 MEMS sensor, used to detect cars in different parts of the State, to the trip computer provides information, allowing users to better control of the car.

And inside the game, behind the various somatosensory function is MEMS gyroscopes (MEMS).

Unmanned aerial vehicles, wearable devices, Internet of things, even now, hot technology industry 4.0, Internet +, and can't do without it, as long as it needs to detect motion where MEMS gyroscopes (MEMS).

165 years ago, Léon Foucault created the gyroscope for scientific research. Today, the small things that make our lives have been dramatically changed, without it, there would be no aircraft, no rockets, no modern life, this is probably his inventors have not thought of. Tiny gyroscopes and make our world a better place.

Two unmanned vehicles collided and who should bear the responsibility

　　December 23, Beijing time, Bloomberg published an article today that, with the development of driverless cars, collided two driverless car accident is almost inevitable, so who is responsible? The current law is difficult to answer this question. But lawyers pointed out that including driverless car manufacturer multiple principals, and even State Governments may need to be held accountable.

　　Following is the full text of the article:

　　If two unmanned vehicles collided causing traffic accidents, who should take responsibility? The answer to this question is: is not clear. But lawyers have seen the opportunities brought about by the traffic accident. They say, computer downtime, they control car collided. Lawyers say due to the driver's seat without a driver, they may require almost all parties to bear the responsibility.

　　Lawyer Calvin Dean (Kevin Dean), "said that in such cases, many people are likely to be accused, including computer programmer, computer manufacturers, algorithm design, Google, maps, companies and even State Governments. For lawyers, driverless car accidents will be fertile. "

　　Google and other makers of driverless cars is believed to eliminate traffic accidents. Supporters say the future, driverless cars could "wipe out" personal injury traffic accidents occurred. But until then, among the first generation of driverless cars, as well as with a conventional car occur collisions are inevitable.

　　Potential obstacles

　　United States National Highway Traffic Safety Administration, the former owner, partner, Venable LLP law firm Dawei·sitelikelan (David Strickland) said, "this situation may occur in the future: does not know who has the responsibility of traffic accident. This is the beginning of the driverless car is more difficult to be accepted by consumers. "

　　Consumer liability concerns will affect the acceptance of driverless cars. This is Volvo, Google subsidiary Mercedes-Benz, Daimler announced that take responsibility for their driverless cars cause. Moschino iPhone case

　　Director of Government Affairs for Volvo andesi·yougensen (Anders Eugensson) said, "we want customers to believe that the technology is reliable, and that is why we are committed to responsible for the traffic accident. We feel that, without such a commitment, we will not sell products to customers. "

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

　　But lawyers and not the driverless car manufacturers this commitment seriously, that it is a marketing strategy. Lawyer Dawei·bulaite (David Bright) said that "every car manufacturer has such a promise: If the problem is in our cars, we'll definitely take responsibility. Soon after the accident occurred, they will say: our car is no problem. "

　　Unpredictable

　　So difficult the problem is, under current law, owners – usually drivers, need to assume responsibility for the accident. If the owner wants to put the responsibility on manufacturers, he or she must prove that the manufacturers fault. But modern products liability law and regulations do not involve unmanned vehicles.

　　Strickland said, "the laws must be revised. There is no legal provision known as driverless car manufacturers need to take economic liability for traffic accidents. "

　　In a traffic accident, a driverless car owners may not need to take responsibility, particularly as they slept in the back seat or "updating Facebook status" case.

　　Not clearly defined

　　Assistant Professor of law, University of South Carolina bulaiente·woke·shimisi (Bryant Walker Smith) said, "no one wants to be prosecuted for their inability to prevent traffic accidents or arrests. "

　　Therefore, involved in an accident the first driverless car owners may sue unmanned technology developers, for such cases to establish jurisprudence. This type of accident is a test of the current insurance system.

　　No clear provisions in the existing case law. In court records and automatic braking or lane keeping unmanned technologies limited.

　　You Gensen noted that Volvo has asked regulators for driverless cars on the road to develop uniform rules, it was concerned that "United States driverless cars of different States will have different rules of the road". Moschino case

　　Google driverless cars to be used to provide a taxi service

　　Driverless cars said the draft rules proposed this month in California, someone is sitting in the driver's seat, ready to manipulate the car. Bill also forces manufacturers to develop monthly reports are driverless cars. Google says it on the draft "serious disappointment".

　　Google will quickly promote the advent of driverless cars. People familiar with the matter said Google plans unmanned vehicle sector into an independent enterprise, and using unmanned vehicles to provide a taxi service.

　　Although lawyers focus on unmanned vehicle safety, in the United States arose as a result of the 33,000 injuries every year in traffic accidents, human error still accounted for more than 90%. Driverless car will drastically reduce the number of such accidents.

　　Smith said, "If the unfortunate enough to be hit by a car, people should want to hurt themselves is a driverless car, perhaps because people can give one or several richer companies claim. "

Intel recruited Co President of Qualcomm responsible for the company s largest

　　

　　Beijing time on November 21, morning news, Intel on Friday appointed wenkata·LUN Duchen Tara (Venkata Renduchintala) for the client and system architecture and networking business group President. He will be responsible for development, chip design, and such business Intel products.

　　Duchen Tara is co-President of the Qualcomm CDMA technologies sector, the sector responsible for Qualcomm's semiconductor business. Qualcomm on Thursday issued a bulletin announcing Duchen Tara's departure.

　　At Intel, Duchen Tara is responsible for operations including PC, mobile, Internet and software, making Intel the second man. He will replace former head of Intel's Rachel NI·zhanmusi (Renee James) some of the work, which the management changes left the service in July this year. Givenchy iPhone 6 cases

　　Insight 64 analyst nasang·buluke wood (Nathan Brookwood) that Intel CEO odd (Brian Krzanich) the hope might be that Duchen Tara join the multiple reporting lines can be integrated.

　　But he also believes that Duchen Tara is able to adapt Intel's culture remains a problem. He said: "in the past, the introduction of outsiders is responsible for the company's key business, Intel's lack of good records. " Givenchy iPhone 6 Case

　　Former Intel Executive, for example, the digital home business ailike·Jin (Eric Kim) and is responsible for wearable device Maike·Beier (Mike Bell) before joining Intel in has a good reputation. However, they were unable to meet Intel's culture.

Early Tesla Model s Super 60 experiencing transmission problems

　　Nowadays, the electric vehicle has become a very popular vehicle categories in the automotive field, usually electric vehicles we will think of Tesla. This company through the open patent, as well as cooperation with other auto manufacturers, has been vigorously promoting the development of pure electric vehicles in the world.

　　Recently, the Plug-In America early of the Tesla company Model s vehicle data survey, close to two-thirds early electronic drive units of the Model s will be up to 60,000 miles (about 96560 km) after the failure of. If their prediction is no problem, the Tesla Model s is not a good news for owners.

　　Although the Tesla launched the pure electric Model s is so impressive, in the review of the consumer reports rankings also received very high marks, but early Model s vehicles into the market still needs to be facing reliability problems. Hello Kitty iphone hello kitty cases for iPhone 5

　　Of course, this is no surprise, although Tesla company developed rapidly, but the company in the automotive sector is still very young, we need to give them more time to correct the error. According to the Tesla company last month released data show that in recent days, the probability of a defective product that they produce has been reduced 50%.

　　Although the new Model s has greatly reduced the chance of failure, but early Model s owners and second-hand sellers still face problems with electronic drive. According to the data of Plug-In America survey, early Model s vehicle power transmission systems may fail, from Tesla owners surveyed data, 60,000 mile point of the Model s will be faulty.

　　It is understood that the report from Green Car Reports show, they had two early Model s owners to data samples, one of the collection covered 327 2012-2013 purchased the Tesla Model s owners, is another major purchases until after 2014 Model s 43 respondents.

　　In the course of investigation, respondents were asked about the vehicle mileage, the car is the power transmission system for repair and repair the vehicle mileage, and so on. Final survey results show that only 77 of early Model model s owners said their car's drivetrain problem does not occur.

　　Of course, because the sample range is not wide enough, it's just a rough estimate results. Coupled with the Tesla company provides warranty period of eight years, each transmission system problems encountered early Model s owners can receive free repairs, only 24-48 hours.

　　In addition, in order to avoid negative effects of Tesla company also will continue to have reliability problems owners of ongoing visits. Tesla has said at the beginning of last month, Model 3 will be released as planned in late March 2016. If some negative news at this time, may affect consumer confidence in Tesla's new models.

Better Windows 10 is gradually changing the rules of the game

　　From previously released Microsoft reports first-quarter financial results of fiscal year 2016, Microsoft this year's result was in line with expectations. Period, cloud computing revenue soaring Office 3,651 guarantees, even some of the struggling business also has been growing for a long time, such as the Bing search engine has turned the corner. Paul Frank iPad Air 2 Case

　　Most importantly, Microsoft Windows released late July 10 operating systems, installed more than 110 million people, it is conservative to say the least, Microsoft's new platform has achieved some success. Recent data from market research firm Gartner released also confirms this, and that Windows 10 could be a game changer, drive growth of Microsoft's various departments.

　　Gartner says, than any previous Windows version, over the next two years, as the business growth in installed capacity up to 50%, "Windows 10 could become the installation one of the most popular version".  Paul Frank iPad Air 2 Case

　　So why does Windows 10 to succeed? Gartner gives a few reasons, first the limit provided by Microsoft for Windows 10 free upgrade promotion strategy of the year, called one of the most successful marketing program in recent years. Furthermore, the tablets fall 2-in-1 device for demand growth, to lead to Windows 10 coverage. In addition, is trying to make the Office more "mobile" institutions, contributes to Windows 10 pace.

　　Windows 10 deathscent Bing live

　　The previous quarter, boosted by growth in revenue, and search each search, Bing search revenues rose 29%, more than $ 1 billion. Nadela is have to bloom, that what is promoting Bing completed the turnaround? Windows 10, now it's only 110 million installations of the operating system, assumed by the year 2017, 50% of enterprises to upgrade to a new system? In other words, today's Bing 20% business revenue from Windows only tip of the iceberg.

　　Of course, Bing search and Google search market share is still less than a, but as the King still had to worry about Bing's on the rise. Growth in recent years has focused on mobile search, Google search engine is limited, one half of the search queries from the desktop, the desktop is the Foundation of making money, but growth undoubtedly poses a threat to its Windows 10. Now Microsoft Windows 10 as a strategy to promote other sources of revenue had worked, it would become one of the key business of Microsoft's revenues, and in addition to Windows 10, its core function of Edge and the Cortana, and Apple devices to cooperate with Bing, Bing search will evolve.

　　Mobile first, soaring cloud-first Windows 10 also

　　Many people complain about Microsoft in the mobile space, but Nader's "mobile first" initiative shows, does not need to sell a lot of smartphones as the point of reference. That's why Microsoft's mobile ambitions into applications and services, and with Windows unity of 10 mobile experience, and focus more on business-experience the evolution of Windows 10 could make up excellent enterprise-class operating system, as the Surface before Pro series tablet with results.

　　Now more mobile enterprise devices, this also means that Windows 10 more in line with their standard, Gartner thinks the next few years will be more than half of the enterprises running Windows 10, both the Surface Pro full version pre-installed product, is experiencing similar Windows 10 mobile, it will naturally become more popular in the enterprise.

　　Meanwhile, Microsoft has the most low-key business: cloud computing. Microsoft of cloud service has is cloud suppliers of preferred one of, with increasingly more enterprise select gave up traditional of data storage and analysis solution programme, instead to cloud computing service for based, promoted Windows 10 Enterprise share listed to 50% does not exaggerated, Microsoft has confirmed Windows 10 is and future Microsoft cloud computing solution programme of core based, regardless of is Azure platform also is Windows, are will as a items service to development.

　　Microsoft, the world's leading software provider status are hard to change, Nadela Windows in the age of 10 are likely to once again change the rules of the game.
