smart phone
Smartphone (in English: Smartphone), is the term given to a class of modern mobile phones that use sophisticated operating system, most of the touch screen is used as a front Mstkhaddmoicom run mobile applications. If no agreement is reached between the manufacturers of mobiles on a common definition of the smartphone, some of them considered a smartphone is a phone that offers the advantages of Tcefhalanturnt and synchronize e-mail and open MS Office files, and has a full keyboard QWERTY, but the definition healthiest and most widely accepted today that mobile phone that works on one of the following operating systems: Windows Phone, Symbian, or its derivatives, Linux or its derivatives and Blackberry. Smart phones are no different from laptops, personal computers or any other device in history, all the smart devices consist of a two-part complementary to each other and are the Hardware, the part physicist possible to the touch, the Software and is part programmatic operator of the device (operating system), who leads the Hardware and you Do your part led. Like Windows and Linux, can not for the device to work without an operating system, or you'll find yourself restricted inside the prison of tags nagging, operating systems in development began at the hands of giant Nokia where he drove us to Symbian OS system and was the first advanced operating system enough to meet simple needs and some complex , in the same time period was Samsung's own Bada OS makes his way system, but Symbian OS excellence was obvious. Where is Wallace 60 and U Aye Kyu-developed operating systems for Alsimbian, while the running Apple OS (iPhone) and Google's Android and Nokia Maemo elaborate systems for Linux system, has seen mobile phones operating on one of these systems Phones smart because it is mostly where all available the conditions precedent (except for the lack of a full keyboard in most devices).
Among the operating systems that are not classified as Jawaladtha Phones Nokia smart feed 40 exclusive and regulations (Proprietary) are working on most mobiles Samsung, LG and Motorola.
Date
The first phone Zkialhatv first smartphone was the IBM Simon; it was designed in 1992 and shown as a product concept that year at Comdex, the computer industry, which was held in Las Vegas, Nevada trade show. He was released to the public in 1993 and sold by BellSouth. In addition to being a mobile phone, also included a calendar, address book, world clock, calculator, note pad, e-mail client, and the ability to send and receive faxes, and games. It was no physical buttons, instead customers use touch to identify phone numbers by finger or create a fax memos optional pen. The text input with a keyboard on the screen "predictive" unique. By today's standards, Simon will be a low-end product to some extent, it lacks a camera and the ability to install third-party applications. However, her appointment raised high time advantage.
The first company designed smart Nokia line of phones is the first of smart Nokia phones starting from 9000 Nokia, released in 1996. The computer distinctive this smartphone palmtop pattern was the result of a collaborative effort of the early successful and expensive personal digital assistant (PDA) by Hewlett-Packard to combine phone Nokia's best-selling around that time, and the first two models model of fixed devices via hinges. Communications are characterized clamshell design, with a feature phone screen, and the user interface and the phone's keypad, and keyboard physical QWERTY keyboard, high-resolution display at least 640 × 200 pixels and user interface PDA under the door. The program is based on the Global Environment Outlook V3.0 operating system, highlight the e-mail and surf the Web based on the text. In 1998, it was followed by the Nokia 9110, and in 2000 the Nokia 9110i, with a review of the enhanced Web capabilities.
Intelligent use of the term used the term 'smart' in 1997 for the first time when Ericsson unveiled the concept phone.
Uses
Smart phones have contributed to many social activities, such as sending and receiving e-mail messages, helping to facilitate the management of companies and projects. In the media it has become far there are no newspaper, media channel or a news organization does not have an application for smart phones which makes it easier to know the news. In the economy we now know as soon as news of the stock market roads and on phones and easily and quickly.
Methods of fall protection
The use of smart phones-which are no longer limited to telephone the just- urgent necessity, that were not really needed daily living accompany us most of the day. So what increases the exposure to the problems of daily use and the most consequential damage and the cost for the crash repeatedly and different situations on hard surfaces. May become the screen or built-in camera or other parts of the main keys Balkhaddh or breakage or disruption under the fall of device or mobile phone, the most important conditions: the speed of the fall and the height and angle of the collision with the ground or different surfaces.
In other circumstances, if the device is going on when he fell with the clock, the protection mechanism to generate torque counter-clockwise working to adjust the rotation of the machine through a compressed gas and store launch in a small cylinder attached protection mechanism. The mechanism for this ability to control the external machining device is a battery, where the positions in the fall or collision certain bombarding the battery from the device to ease the bloc or dissipating the energy generated by the collision. (Disintegration of cell phones mechanism when they occur and collisions with the ground were scattered in the old hardware, specifically the Nokia 3310), even with the use of protective covers and labels, you may not get effective protection from the impact of unexpected shocks in terms of form and injury. The need for prevention and protection -obfalah Aalah- to these sensitive devices; pushed toward those interested in research and investment in engineered and developed to help reduce the risk of hurting devices and smart phones due to fall freely. This protection technology and its mechanism to provide a sensor device and at least one dependent can predict the status of a free fall (Free Fall) and the status of the machine simultaneously with the fall, in addition to the direct protection mechanism to change the status of the fall directing the center of gravity or relocate the device. Based on the principle of protection against changing the status of the device through recycled or his heart or trade sideways for the fall track mechanism, in order to guide the machine a block in the opposite direction to the point of falling to relieve the momentum and the impact of the collision.
It can also provide protection mechanism of the process of attracting or hide the keys and side buttons or keyboard to mitigate the impact of colliding directly with the ground or different surfaces. If the device or phone with a link headphones or charger cord, the protection -and mechanism Alsagot- to take advantage of these links and stick to them and prevent the drop from the socket, and thus attract the machine towards the socket in a way acts as a brake and reduce the speed of the fall; which provides the user a chance to try to pick up device or mitigate the force of the collision.
More characteristic of this mechanism and there is capable of storing the previous fall information from the high speed rotation and repeated to the circumstances of the fall similar memory, to take advantage of this information to guide the protection mechanism more effectively when speed is repeated, or send that information to the manufacturer for use in new hardware design.
Apple got a patent for a special safeguard mechanism apparatuses iPhones, which boils down to discuss the following points: • employ your engine vibration device to control the angle of the fall and its budget. • Provide hardware sensors are positioned on the interior of her paintings (Accelerometer, GPS, Gyroscopes and an Ultrasonic emitter) to send information about the speed and direction, and the position falls. • An explanation of the mechanisms through which the air intake so as to ease the speed of the device when he fell. • Propose to take advantage of shipping and wire connection speakers in braking the fall, and the use of compressed gas capsules.
