Беспроводная зарядка

Сегодня беспроводная зарядка кажется чем-то инновационным, сверхсовременным. Но на самом деле, данная технология была открыта достаточно давно, более 100 лет назад. Просто раньше ей не находилось применение, не было надобности заряжать батареи и аккумуляторы на расстоянии. Суть технологии заключается в том, что при помощи электромагнитного поля переменного типа в закрытых проводниках образуется электрический ток. И в результате этого происходит зарядка аккумулятора. В настоящее время это пригодилось для того, чтобы заряжать смартфоны, которые, как известно, довольно быстро разряжаются в условиях постоянной эксплуатации.

Беспроводная зарядка смартфона

Конечно, ученым придется еще потрудиться, чтобы создать более совершенное устройство. Например, КПД беспроводной зарядки составляет всего 80%, хотя в таких же пределах находится и коэффициент полезного действия проводного аналога. К тому же, на расстоянии около 50 сантиметров действие гаджета ослабевает, а при дистанции в 1 метр он становится фактически бесполезным.

Возникает вопрос – а зачем тогда нужен такой прибор, если в домашних условиях можно воспользоваться, в принципе, и стандартной зарядкой? Да, все правильно, дома можно использовать и привычные зарядки. Однако производители планируют оборудовать терминалами Qi общественные места – торговые центры, кафе, магазины, аэропорты, вокзалы. И такой терминал уже установлен в Лондоне, в аэропорту Хитроу. Это действительно удобно, так как туристы часто сталкиваются с проблемой разряженных телефонов. А носить с собой постоянно пауэр-банк тоже не всегда представляется возможным.

Что представляет собой стандарт Qi

Рядом со словом «беспроводная зарядка» вы нередко сможете встретить и приставку Qi. Это не бренд и не модель гаджета. Это некий стандарт технологии, разработанный ассоциацией WPC, которая расшифровывается как Wireless Power Consortium. В данную ассоциацию входят ведущие производители смартфонов, а также целый ряд компаний, специализирующихся на изготовлении электроники. Таким образом, представленную технологию можно применять для телефонов практически любого бренда.

Приставка Qi никак не расшифровывается, это скорее символическое название, которое означает энергию ци. Согласно китайской религии, эта энергия циркулирует по Вселенной. В данном конкретном случае она означает энергию, при помощи которой происходит беспроводная зарядка смартфона. В то же время, пользователь понимает, возможно ли зарядить его устройство по этой технологии. Это примерно как стандарт разъемов USB, когда уже точно знаешь, как выглядит порт, и сразу можешь выполнить подключение.

Благодаря использованию Qi, заряжающее устройство автоматически распознает гаджет, уровень имеющегося заряда в аккумуляторе, а также самостоятельно отключается, чтобы сэкономить электроэнергию.

Влияет ли беспроводная зарядка на здоровье человека

Когда только появились мобильные телефоны, в обществе стали разгуливать мифы об их негативном влиянии на человека. Приписывали даже риск онкологических заболеваний. Затем та же участь постигла смартфоны, в которых тоже увидели опасность для здоровья. Сегодня же критике подвергается беспроводная зарядка. Главным аргументом выступает тот факт, что само по себе электромагнитное поле оказывает воздействие на организм человека. Правда, нужно уточнить, что это поле должно быть достаточно мощным. Бытовые модели устройств не вызывают опасения, а представители ассоциации WPC и вовсе заявляют, что излучение из гаджета не относится к ионизирующим, то есть, не радиоактивно. Здесь с ними можно согласиться, но только отчасти. Как уже говорилось, бытовая модель не обладает большой мощностью. А вот промышленные станции, работающие по этой технологии, и позволяющие осуществлять зарядку смартфонов на расстоянии почти в 10 метров – пока еще нельзя назвать безопасными. Но все покажет время, сейчас рано судить, так как недостаточно данных.

Для каких телефонов есть беспроводные зарядки

С учетом того, что в ассоциацию Wireless Power Consortium входят практически все ведущие бренды смартфонов, то беспроводные зарядки рассчитаны на телефоны большинства производителей. В частности, это такие лидеры, как Apple, Samsung, Sony, HTC, LG, Asus и ряд других. Однако, следует понимать, что технология стала использоваться относительно недавно, потому старые модели, по естественным причинам, ею не оснащались. Только новые смартфоны, и то, далеко не всех моделей, могут заряжаться по стандарту Qi. Если вы хотите приобрести себе подобное устройство, то необходимо уточнять у продавца, возможно ли будет применять к телефону беспроводную зарядку. Но тенденция такова, что в скором времени уже все модели смартфонов и планшетов будут оснащены стандартом Qi. По крайней мере, все идет именно к этому.

Updated mobile viber

VIBER success is not only that it is a convenient communication tool, but also that it is updated regularly. Although it would seem, why should developers worry about it? Well, initially released high-quality and feature-rich application, well, enough. Many other messengers remain at the initial stage, and in some at all, that neither the update, it works worse and worse. And the most interesting thing is that users continue to use them instead of simply deleting and finding something more suitable. But, probably, it’s not for nothing that Viber has become so popular, and the next improvements are the best proof of that. One significant update occurred in 2018, then the interface was revised. The developers found it necessary to slightly change it to make users more comfortable. At the same time, the speed of work also increased, so that the owners of low-end smartphone models could also use the instant messenger. And it brought positive results. But the developers did not stop there, and already in early 2019 pleased their customers with regular improvements. But let’s consider it step by step.

New Viber Interface

In general, this element of the difficulties and did not arise earlier. Everything was quite comfortable, concise and simple. Viber mobile version completely met the modern requirements of users and did not cause any complaints. But now the interface has become even clearer, you can easily find the functions you need to reduce the time for sending messages or changing settings. Need to quickly find a chat button? No problem! The icon is located at the bottom of the screen. There are also frequently used icons such as “More” and “Calls”. But, it is worth getting used to the fact that the section in the settings menu now leaves not to the left, as before, but to the right. But this is a matter of time, literally after a couple of days of intensive use, you get used to this innovation. Also pleased with the main section of Viber, which lists group chats and contacts – it received a rich white color, which is visually more comfortable for the eyes. In addition, this innovation meets modern design standards. In general, today the trend in the field of information technology is such that usability, that is, the maximum convenience of users, comes to the fore. And this is understandable – if the user doesn’t like something, he simply goes to the competitor’s application. And because serious companies carefully monitor behavioral factors.

The main functions of Viber

New chat features

It is quite natural that the chat in Viber has also been updated. Calls are calls, but a huge part of the audience prefers to correspond, after all, this is an instant messenger. First of all, the dialog box has become wider, therefore, it can accommodate more text than before. Let not all write long messages, but sometimes it is useful. For example, when sending out advertising messages or for corporate needs. And in general, a perception has become better. As for the chat’s background, it is automatically assumed white, supposedly it is the most convenient and unobtrusive. In general, it is. On a white background, it is easier to see the text. But if you want to make the background different, you just change it through the settings menu, you can also add a picture as a background. Viber update also affected the status of messages. How many times have you communicated with someone, but do not know if the other person received your message? And sit, wait, wondering if it was delivered, did the subscriber read it? It even caused some irritation, especially if it was necessary to quickly get an answer. Well, now this problem is solved. After updating the application, checkboxes appeared in the dialog boxes indicating the status of the message. If there is a check mark, the message has been sent, two black check marks indicate delivery. And when the interlocutor reads the message, the checkboxes are colored purple. However, do not worry, the application still has an incognito mode. Also updated Viber allows you to better see the sent pictures and videos. Before this, the image was automatically cropped, it turned out to be a square, and the whole picture could only be seen after opening. Now it appears in the dialog box in full quality and larger. In fact, you can not even open it at all. Bubbles. In fact, not every user uses them in correspondence. Smilies – yes, but babbly somehow do not survive. On the other hand, there are people who communicate with them only with their help. Instead of a dry “Hi”, you can send a bright and attractive bubble that conveys the sender’s mood and causes positive emotions to the recipient. Well, isn’t it lovely? It seems a trifle, but even this is thought up by the developers.

Viber speed

This is a sad topic for many instant messengers. Some of them frankly slow down, others hang in case of poor communication, a number of other applications do not allow you to quickly send a message. But for Viber, such difficulties usually did not exist. However, the developers could not get past this point and decided that the update should touch the speed of work. As a result, messages began to be sent even faster than before, almost doubled! Similarly, one has to wait much less for an answer. In fact, chatting is obtained as close as possible to a “live” conversation. In just a few minutes, users can discuss interesting or important topics without losing precious time. At the same time, notifications about the delivery of messages are also not long in coming. Of course, the overall work of the messenger has accelerated. Again, for some, this is quite a critical moment, because there is not always free time to wait. Need to instantly send a message and go about your business? You just send it, and you can not worry about anything!

Personal security in the messenger

At the time of scammers activity on the Internet, the Viber team simply could not take in mind the care of the safety of their customers. In developing updates to this issue was given no less attention than all the rest. Now messages are encrypted with a special protocol, and unauthorized persons will not be able to access. Just as they will not be able to hack an account to obtain personal data of users. In addition, you can literally retire with someone from the members of the group chat. You just have to go to a private chat and that’s it; you don’t even need to “blow” your phone number if you don’t want the other person to recognize it. This is very convenient for those who do not wish to disclose their phone numbers, for example, for owners or managers of large companies.

The results of the new Viber

These were the main points that affected Weiber. The developers promise to add more innovations in the near future. In particular, it announces a group video call, in other words, a video conference. There are no dates yet, and it is not known when to expect this function. But the team is already actively working on it, trying to make Viber perfect from all points of view by the instant messenger. And we will wait for the next update to fully enjoy the quality of communication.

What is NFC?

Many uninitiated users do not know what NFC is. Meanwhile, this is quite a useful feature that is present in mobile gadgets – smartphones and tablets. True, it should be said that not all device models support this option yet, but such models are getting smaller. Manufacturers understand that the presented function will soon become one of the most popular, as it makes life easier for smartphone users. But first things first.

What is it NFC

As you might guess, this is an abbreviation. The full name of the option is Near Field Communication, and it makes it clear that the function implies communication. And there is! NFC is contactless proximity. Its peculiarity is that, firstly, it works at high frequencies, and secondly, the radius of action is no more than 10 centimeters. It would seem, why do we need such technology, if Bluetooth already exists, and, moreover, its range is much larger? However, there is an advantage. It is the connection speed. Due to NFS, the connection is much faster, and there is no need to synchronize the two devices, confirm the connection, etc., as is the case with Bluetooth. That is, everything happens much faster, and this is the convenience for the user. As for the small radius of action, then this is not such a minus. Due to the need to adhere to such a small distance between two devices, NFC is considered more secure. It is difficult to steal data or accidentally transfer it to someone else, as it happened, again, with Bluetooth. Near field communication is used for two purposes:
File transfers between two devices;
Payment of purchases and services without direct use of a bank card.

NFC support by mobile device

In order to use the presented technology, it is necessary to first understand whether it is supported by your gadget. There are two ways to check this. The first is to search on the back panel of the device or the battery for the corresponding inscription, or the full name of the option, or an abbreviation. The second is to enter the menu item of the gadget settings, then select the “More” tab, and the NFC line will appear in the list that opens. The switch should be activated, and you can also enable the Android Beam option.

How to implement NFC

First of all, both devices, between which the file transfer will take place, must support this technology and the Android Beam function. Neither one nor the second gadget should be blocked. When the devices are idle, vibration and a beep will occur. There will also be an additional signal-alert after the transfer of data. Up to this point, it is impossible to separate the gadgets and distance them from each other Now we will analyze in more detail how to transfer certain files.

Photo and video content

To transfer photos and video files via NFC, you need to open the necessary content on the device. Then attach this device to another, backed. We are waiting for the connection to take place; this may take a few seconds since it is not always possible to understand exactly where the NFC chips are located on both gadgets. When the connection is confirmed, on the donor device, click on the display to activate the file transfer. After the process is completed, the gadget will beep.

Link and applications exchange

NFC is convenient to use for quick exchange of applications and links. For example, you have found an interesting web resource or application and want to share or with your friend. But instead of copying a link to a website or application, performing a variety of actions related to searching for them and sending via instant messengers, it’s enough to bring your smartphone to a friend’s smartphone when the application or link is open. On the second device, the content page will open automatically. It is very simple, and it also saves time.

Payment of purchases and services

Due to NFC technology, you don’t have to carry a bank card with you anymore. Today, most large stores use terminals that support this feature. Of course, at the checkout, it would be better to clarify this issue if we are talking about an unknown store. But in supermarkets, as a rule, this is already in the order of things. Surely, you have seen some of the buyers bring their gadget to the terminal and thereby make the payment. Here is a vivid example of how to use the NFC for payments in stores. In Ukraine, this opportunity appeared in early 2017. Moreover, it is not only about shops, but also gas stations, cafes and even public transport – modern trolley buses. You can find out if the terminal supports this feature by the icon where the hand is shown and stripes emanate from it (similar to the Wi-Fi icon). It can also simply written PayPass.

Special tags – extra comfort

It would be strange if such a useful technology had not been improved, and not used for other purposes. Manufacturers have developed special marks, they are also called tags. These devices have a small compact size, due to which they can be carried in a pocket, in a bag, backpack, glued to the desktop, and even on the key ring. Actually, anywhere, just to be able to securely fasten. What are they needed for? It’s simple. The user can write on a similar label certain settings for your gadget. For example, you want your workplace smartphone to quickly switch to silent mode. But to customize each time manually, no desire. What are we doing? We acquire a label, using the corresponding application, we read it, and then we enter information that when connected with this label, the device automatically switches to the desired mode. Then we attach the label to someplace on the desktop where it will not interfere. Now when the device gets into the range of the tag, it will automatically go into silent mode. You can also use tags for the following purposes:

  • Alarm setting;
  • Profile settings – silent, normal, etc .;
  • Flight mode;
  • Data transfer;
  • Activation/deactivation of Bluetooth and Wi-Fi;
  • Setting display parameters – lock, auto-rotate, set brightness, etc.

Thus, it is possible to arrange tags in key locations of a room, apartment, or study. And, instead of changing the settings manually in the smartphone through the menu each time, it will be enough just to attach the device to the label. Conclusions Now, knowing what NFC is, you probably understand how this technology will become popular and in the near future. It is likely that for the next 2-3 years only those models of devices that support the presented option will be on sale. And after 5 years in general, most likely, it will not be necessary to carry a bank card with you. After all, you can pay for everything directly via a smartphone. We can definitely say that this is the technology of the future, which is already gaining wide popularity today!

How to find a phone

How to find a phone

How to find a phone if it was lost or stolen? Probably, this question was asked almost every second user. In the era of push-button cell phones, this problem did not arise, since their cost was not too high. Lost? Went to buy another one! But with smartphones everything is different. First, by themselves, they are quite expensive. Secondly, they store important information, including access to a bank card. The loss of a mobile device becomes a real problem, and therefore it will not be superfluous to know how to find a phone in which case.

Determining the location of Android a smartphone

In order to find out the location of the mobile device, as well as perform the necessary operations with it, you should go to the android.com/find page and log in to your Google account. When using multiple devices, such as a smartphone and tablet, at the top of the page, simply select the gadget you need. Thus, you can block a stolen device or erase data from it that is not intended to be viewed by unauthorized persons. However, in order to perform these actions, you will need to “bind” the Android device to your Google account in advance. After that, you can find the phone using the search options Wi-Fi, GPS or via mobile networks. Moreover, you can make calls, even in cases where the SIM card was reinstalled. What steps should be taken to track the device? First of all, go to the Settings menu, follow to the Security section, and from it to the Device Administrators item. Secondly, we confirm with the help of a check mark that you give permission to the resource to lock the screen, change the password and delete files from the smartphone. Perform activation. When you first visit the service, you will have to agree to the use of data on the location of your gadget by the dispatcher. After these simple actions, you can control your device at a distance through Google, which is very convenient. At the same time, it is important to remember one nuance – the control of a smartphone or tablet is possible only if the device is connected to the Network, and all accounts on it are saved. This is quite logical because when deleting accounts, the service will not be able to recognize your gadget, which means it simply will not be able to find out how to find the phone. And, of course, in the absence of an Internet connection, it is also impossible to search.

Phone search via IMEI

Each device has an individual serial number consisting of 15 digits. This number also referred to as a code, is called IMEI. In fact, this is encrypted data about the device, and they are displayed in the network of mobile carriers. You can find the provided code on the package from the gadget, in the warranty card or via dialing * # 06 # – in this case, the code will be displayed on the screen. In order to take advantage of this opportunity, you will need to enter the code in the global search base on the page goo.gl/fdZAk5. It would be best to write down your phone’s IMEI number in a Word document or notebook, so that, if necessary, do not search for too long. Such information should always be at hand to avoid wasting time.

Why you need it

Not many users think about the safety of their property. Some people think this is a useless precautionary measure, someone is stopped by superstition, while others are simply lazy. Although many do not know about such features of modern technology. And why? After all, there is the police, who in case of theft will quickly find the phone and return it to its rightful owner. In fact, relying solely on law enforcement agencies is not very reasonable. First, thefts occur every day, thousands of them in the country. If the police tries to search for all the missing smartphones and tablets, it simply will not have time to solve other crimes. And how to find the loss, if the victim often does not even remember when he last saw the device? Perhaps he left it in a cafe, perhaps pulled in transport, or in a crowd.

In such conditions, the work of law enforcement agencies becomes difficult, and an attacker takes only 15-30 minutes to sell a gadget for disassembly or a pawnshop. Secondly, when it gets into the point of purchase of equipment, the device is immediately disassembled into parts or turned off. And you will not be able to reach it. In addition, all data is deleted from the phone, and even if the police find a smartphone in one of the pawnshops, it will be difficult to prove that it is yours. No, it is, in principle, possible, but where is the guarantee that the gadget will not be sold to someone? Or do not redirect to another city where the smartphone is completely lost. You should contact law enforcement agencies. But you greatly facilitate the work of the police, if you can specify how to find the phone. Then the task force will be able to immediately go to the place and withdraw the loss. This feature is also extremely important for those who have installed an online banking application. If you do not want the attacker to go to your personal account in the bank and withdraw all the money, you must be able to block the phone. Thus, you can not only return your mobile device but also prevent theft of money from a bank card. Not to mention the fact that some thieves are not averse to taking a loan, which the smartphone user will have to return. And it is much more difficult and troublesome than to go to the necessary service and connect your phone or tablet to it.

Targeting to advertise your business

The word ” Targeting ” s an incomprehensible term for many Internet users
However, it is not surprising, because it is a highly specialized concept used in Internet marketing and web analytics. For the average user, this term is of no interest. But for the business owner, SMM promotion specialist, PR manager, on the contrary, this is an important and extremely useful tool.

Targeting concepts

Simply put, targeting is a mechanism used in marketing. It is needed in order to select from the millions of users exactly the target audience to which you want to convey information. Correct setting of the targeting will allow you to identify the audience by such criteria as gender, age, place of residence, preferences in music, clothing brands, hobbies, etc. What is it for? Very simple. A customer, such as a sportswear store, has a certain budget that he is willing to spend on an advertising campaign on the Internet. Accordingly, he must be sure that commercials or newsletters reach a potential buyer. Who can be assigned to this category? This is an adult, male or female, fond of sports. That is, those who may be interested in sportswear. These men or women should live in the country or region where the store sells. It makes no sense to show ads to a person living abroad, because he simply can not make a purchase. Accordingly, the store owner does not make sense to pay for displaying advertising to this user. Thus, we see that advertising is the most effective targeting. It will be shown only to those who are really able to respond to it. And at the same time, do not pay extra money for shows that will be useless.

Differences between targeted and contextual marketing

It may seem to an uninitiated person that both of these types of marketing are identical. The owner of a store or company may have the idea of ​​“setting up targeting now,” and users will immediately see contextual advertising in banners. In fact, these are completely different things, and even their goals are different. Targeting marketing is aimed at users who meet specified criteria. And here it does not matter whether a particular user was looking for an advertised product. Perhaps he had no idea at all about the existence of such a product. And, having learned, can become a potential buyer. Contextual marketing is aimed at those users who have already searched for the product or service they need. Consequently, they will be highlighted advertising product, which they have already been interested in, and in recent times. After six months or a year, if the user is no longer searching for the thing he needs, then the ad will stop flashing offers related to this thing. Thus, it becomes clear that the task of contextual marketing is to respond to specific user requests, and the task of targeted marketing is to find these users. And it is important to understand. Since contextual marketing attracts people who can already be called potential customers. It just redirects them to you. And targeting makes it possible for a person to create a desire to become a buyer, to push him to this step. So, these two types of advertising should not be considered interchangeable. And you need to know which one will work in each case. On the other hand, they work excellently together, although they require a larger budget for the marketing campaign.

 

The Importance of Targeting Settings

Before proceeding to the settings, you need to understand which of them will be needed. And for this, data analysis is used. Data is most easily collected from cookies, with which you can determine the interests, tastes, needs of users, as well as their financial capabilities. Absolutly, such painstaking and monotonous work, as analysis, requires perseverance and attentiveness, or the involvement of appropriate specialists, who will be engaged in this work. After receiving the data and analysis, you can get a complete picture in the form of a graph or diagram. These are the most convenient solutions that allow you to quickly and easily see the information you are interested in. Now, let’s talk about what parameters and how to set up targeting is best. There are actually not many such criteria: • Geographic location – advertising will be shown only to those users who live in your region / country: • Socio-demographic parameter – gender, age, place of work or study, approximate income level; • Show time – advertising is shown exactly at the time when users are most likely on the Internet; • User behavior – it is determined that he was searching the network, for example, “buy a phone”; • Interests of users – advertising is shown only to those people who are interested in this or that area. By making the sample you need, you will be able to reach “your” target audience and significantly increase your sales.
