Emerging technologies mobile phone

Mobile phones have become indispensable and now play a big role in the life of everyone. With the current technology that made people and Nations closer, mobile and handheld devices can truly be considered innovations and great inventions. Gone are the days when one has to go home for the first time before he can use the telephone or go to a public phone booth to make an important call to a loved one or business contact. With the presence of cell phones, everyone has now gone wireless. Communication, in fact, made it very easy for everyone.

Mobile phone, as the name suggests, provides mobility. He is the portable communications device. One can bring it anywhere. Is made possible by satellites that transmit signals to the phone send and receive. It is very convenient, as you can use it anywhere regardless of the time and region.

People everywhere saw the evolution of communication technology. A phone that uses wires to one that does not require either. From analog to the wireless. In some places, cordless phones were provided with signals of network company. Elsewhere, a simulated card in inserted into the phone to grab and receive signals and send as well. These phones use the concept of theories of transmission and signal radio allowing two-way communication with conversation more clearly and in real time.

The analog phones that only allowed voice and call conversation evolved the cell phones that have text messaging capabilities. It's another appearance in the world of mobile technology. A person can send a text message that will be received by the other party. This message is sent through a sign to a gateway which it transmits to the receiving party.

At the turn of the 20th century, mobile phones have become more of a trend and companies began to make it look more sophisticated. Phones started with large sizes that transformed to the minors and then again became greater. Developed very much like how has computers. Nowadays, mobile phones are not just for communication. Originally, he had the voice call function, but since that technology is growing day by day, the mobile technology grows along with it. Mobile phones are now created using that are beyond simple communication and different functions. These functions are constantly updated and additional resources are created every day.

Mobile phones also serve as mp3 players and/or storage units of audio, video, where users can save audio files and listen to music. Mobile phones are now also equipped with cameras that come in different pixels, allowing people to take photos anywhere, anytime. Almost all mobile phones these days are designed with games, alarm clock, calculator, organizer, dictionary and more. These are now considered only the basics. Some mobile phones now updated can take video clips and still photos of which can be downloaded to your computer for different purposes. Many mobile phones are also designed with touch screen features, where a person doesnâ € ™ t need to tap the keyboard anymore. The phone screen is designed to recognize the commands as the tip of your finger touches the screen.

In addition, mobile phones are now used as computers. With General Packet Radio Service (GPRS), internet browsing is now made possible. GPRS is used for transmitting IP packets that allow users to use the internet wherever they go. People also use their mobile phones in banking transactions where they can send and receive money via phone.

Several high-tech capabilities are continually being studied and applied to mobile phones. Not too long ago when 3 g system was developed. It enables users on the same network call each other with real-time camera. Through this system, we can actually see the person who he is calling to talk to him. Long before people finally get to grips with the just released 3 g system, many companies are now researching the larger system that is the fourth generation or 4 g system. Researchers at the new project as a system with faster connection speeds reach 100 Mb per second. This is seen to provide a better quality of the call.

Mobile phones are not just for personal use, as it was in the past. With mobile phones, reporters and journalists can now take and film news. Surveillance and security system are also possible.

He is seen in the near future that mobile phones are more likely to replace notebooks. With the new mobile phones coming out in the market, visualizing and working on documents found only on computers are now possible. He is also seen to replace entertainment devices with all new mobile phones have features entertainment.

Cell phones not only play a big part in technology. Mobile phones also show fashion and style. So, to make these phones more attractive and appealing, manufacturers produce these phones in different colors, size, shape and style.

Mobile phones are, in fact, one of the major contributions of technology. He went far beyond what a man can imagine. Now, with the emergence of mobile technology, everyone just canâ € ™ t live without one.

Battery – Make Electronic Objects Mobile

A battery is a device that stores chemical energy and is available in an electric form. The batteries contain a series of electrochemical devices that contains one or more fuel cells, galvanic cells and flow cells. This electric battery is an interconnected array of one or more than one voltaic cells that are used in the cars, in torches, laptops, digital watches and almost every electronic goods that we use in our daily life.

Series of battery cells

The cells in the battery are connected either in parallel, in series or in both combinations. While the parallel combination of cells has the same voltage power as a single cell, it can supply a higher current than a single cell can. The parallel arrangements, however, suffer from a recurrent problem. If one cell discharges faster than its neighbor cell, then current will flow from the full cell to the empty cell, thereby wasting a lot of power and causing excess of overheating. Another marked disadvantage is if one of the cells gets short-circuited due to an internal fault, then its neighbor will be forced to discharge its maximum current into the faulty cell, thereby leading to sudden explosion.

The capacity of a battery to store charge is often expressed in ampere hours [1 A.h = 3600 coulombs]. If the battery can provide one ampere [1A] of current for completely one hour then it is said to have a real-world capacity of 1 A.h.

Types of batteries

There are some common battery types that are used in everyday life. The different types include rechargeable and disposable batteries, homemade cells, and traction batteries and flow batteries.

Disposable batteries

Also called primary cells are intended to use only once until the chemical changed that induce electrical current supply are complete and the battery is then discarded. They are commonly used in smaller and portable objects with low current drain. They are usually contained in light drain and heavy drain appliances, digital cameras, watches, computer clocks, and hearing aids.

Rechargeable batteries

These are secondary cells that can be recharged after they have been drained. This is done by conveniently applying externally supplied electrical current that reverses the chemical reactions that usually occur in use. It is used in appliances like alarm systems, vehicles, vacuum tube radio sets, absorbed glass mats etc.

Traction batteries

These batteries are designed to provide power to move vehicles like electric cars and tow motors. A peculiar characteristic of traction batteries is the electrolytes in the batteries are gelled.

Flow batteries

They are a special class of battery that stores additional quantities of electrolyte outside the main power cell of the battery and are circulated throughout by pumps or through movement. They have a high capacity and are specially used in the marine appliances.

So whether it’s your car, PC, laptop cell phone or MP3 player, the batteries are almost everywhere to make you electrically mobile.
