Some about SMS

Short Message Service in short for it is call SMS, it is a text messaging service component of phone, web, or mobile communication systems, using standardized communications protocols that allow the exchange of short text messages between fixed line or mobile phone devices. SMS text messaging is the most widely used data application in the world, with 2.4 billion active users, or 74% of all mobile phone subscribers.The term SMS is used as a synonym for all types of short text messaging as well as the user activity itself in many parts of the world. SMS is also being used as a form of direct marketing known as SMS marketing. SMS as used on modern handsets was originated from radio telegraphy in radio memo pagers using standardized phone protocols .as a means of sending messages of up to 160 characters,to and from GSM mobile handsets.Since then, support for the service has expanded to include other mobile technologies such as ANSI CDMA networks and Digital AMPS, as well as satellite and landline networks.Most SMS messages are mobile-to-mobile text messages though the standard supports other types of broadcast messaging as well.

The Short Message Service – Point to Point (SMS-PP) was originally defined in GSM recommendation 03.40, which is now maintained in 3GPP as TS 23.040.GSM 03.41 (now 3GPP TS 23.041) defines the Short Message Service – Cell Broadcast (SMS-CB), which allows messages (advertising, public information, etc.) to be broadcast to all mobile users in a specified geographical area.
Messages are sent to a Short message service center (SMSC) which provides a "store and forward" mechanism. It attempts to send messages to the SMSC's recipients. If a recipient is not reachable, the SMSC queues the message for later retry.Some SMSCs also provide a "forward and forget" option where transmission is tried only once. Both mobile terminated (MT, for messages sent to a mobile handset) and mobile originating (MO, for those sent from the mobile handset) operations are supported. Message delivery is "best effort", so there are no guarantees that a message will actually be delivered to its recipient, but delay or complete loss of a message is uncommon, typically affecting less than 5% of messages. Some providers allow users to request delivery reports, either via the SMS settings of most modern phones, or by prefixing each message with *0# or *N#. However, the exact meaning of confirmations varies from reaching the network, to being queued for sending, to being sent, to receiving a confirmation of receipt from the target device, and users are often not informed of the specific type of success being reported.

About Online Shopping Site Ebay

eBay Inc. is an American internet consumer-to-consumer (c2c) corporation that manages eBay.com, an online auction and shopping website in which people and businesses buy and sell a broad variety of goods and services worldwide. Founded in 1995, eBay is one of the notable success stories of the dot-com bubble; it is now a multi-billion dollar business with operations localized in over thirty countries.eBay expanded from its original "set-time" auction format to include "Buy It Now" standard shopping; shopping by UPC, ISBN, or other kind of SKU; online classified advertisements; online event ticket trading (via StubHub); online money transfers (via PayPal  and other services.
The online auction website was founded as AuctionWeb in San Jose, California, on September 3, 1995, by French-born Iranian-American computer programmer Pierre Morad Omidyar (born June 21, 1967) as part of a larger personal site that included, among other things, Omidyar's own tongue-in-cheek tribute to the Ebola virus.One of the first items sold on eBay was a broken laser pointer for $14.83. Astonished, Omidyar contacted the winning bidder to ask if he understood that the laser pointer was broken. In his responding email, the buyer explained: "I'm a collector of broken laser pointers."The frequently repeated story that eBay was founded to help Omidyar's fiancée trade Pez candy dispensers was fabricated by a public relations manager in 1997 to interest the media, which were not interested in the company's previous explanation about wanting to create a "perfect market"^.This was revealed in Adam Cohen's 2002 book, The Perfect Store,and confirmed by eBay.
Chris Agarpao was hired as eBay's first employee and Jeffrey Skoll was hired as the first president of the company in early 1996. In November 1996, eBay entered into its first third-party licensing deal, with a company called Electronic Travel Auction to use SmartMarket Technology to sell plane tickets and other travel products. Growth was phenomenal; in January 1997 the site hosted 2,000,000 auctions, compared with 250,000 during the whole of 1996.The company officially changed the name of its service from AuctionWeb to eBay in September 1997. Originally, the site belonged to Echo Bay Technology Group, Omidyar's consulting firm. Omidyar had tried to register the domain name echobay.com, but found it already taken by the Echo Bay Mines, a gold mining company,so he shortened it to his second choice, eBay.com.(Echobay.com is now owned by Echobay Partners, Ltd., a private equity firm based in Nevis.)
In 1997, the company received $6.7 million in funding from the venture capital firm Benchmark Capital.
Meg Whitman was hired as eBay President and CEO in March 1998. At the time, the company had 30 employees,half a million users and revenues of $4.7 million in the United States.eBay went public on September 21, 1998,and both Omidyar and Skoll became instant billionaires. eBay's target share price of $18 was all but ignored as the price went to $53.50 on the first day of trading.
As the company expanded product categories beyond collectibles into almost any saleable item, business grew quickly.In February 2002, the company purchased IBazar, a similar European auction web site founded in 1995 and then bought PayPal on October 14, 2002.
In early 2008, the company had expanded worldwide, counted hundreds of millions of registered users, 15,000+ employees and revenues of almost $7.7 billion.After nearly ten years at eBay, Whitman made the decision to enter politics. On January 23, 2008 the company announced that Whitman would step down on March 31, 2008 and John Donahoe was selected to become President and CEO.Whitman remained on the Board of Directors and continued to advise Donahoe through 2008. In late 2009, eBay completed the sale of Skype for $2.75 billion, but will still own 30% equity in the company.
In July 2010, eBay was sued for $3.8 billion by XPRT Ventures that accused eBay of stealing information shared in confidence by the inventors on XPRT's own patents, and incorporated it into features in its own payment systems, such as PayPal Pay Later and PayPal Buyer Credit
On December 20, 2010, eBay announced its acquisition of a German online shopping club, brands4friends.de, for €150 million ($197 million) to strengthen the company's interests in the fashion industry in Europe. It is subject to regulatory approval and expected to close it in the Q1 2011.

About the Infromation of Dial-up Internet access

Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network to establish a dialled connection to an Internet service provider (ISP) via telephone lines. The user's computer or router uses an attached modem to encode and decode Internet Protocol packets and control information into and from analogue audio frequency signals,respectively.
Modern dial-up modems typically have a maximum theoretical transfer speed of 56 kbit/s (using the V.90 or V.92 protocol), although in most cases 40–50 kbit/s is the norm. Factors such as phone line noise as well as the quality of the modem itself play a large part in determining connection speeds. Some connections may be as low as 20 kbit/s in extremely "noisy" environments, such as in a hotel room where the phone line is shared with many extensions, or in a rural area, many kilometres from the exchange. Other things such as long loops, loading coils, pair gain, electric fences (usually in rural locations), and digital loop carriers can also cripple connections to 20 kbit/s or lower.
Dial-up connections usually have latency as high as 300 ms or even more, this is longer than for many forms of broadband, such as cable or DSL, but typically less than satellite connections. Longer latency can make online gaming or video conferencing difficult, if not impossible. First person shooter style games are the most sensitive to latency, making playing them impractical on dial-up. Many modern video games do not even include the option to use dial-up. However, some games are capable of running on 56k dial-up.
An increasing amount of Internet content such as streaming media will not work at dial-up speeds.
Analog telephone lines are digitally switched and transported inside a Digital Signal 0 once reaching the telephone company's equipment. Digital Signal 0 is 64 kbit/s, therefore a 56 kbit/s connection is the highest that will ever be possible with analog phone lines.

About 3D printing

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material.3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.
Standard applications include design visualization, prototyping/CAD, metal casting, architecture, education, geospatial, healthcare and entertainment/retail. Other applications would include reconstructing fossils in paleontology, replicating ancient and priceless artifacts in archaeology, reconstructing bones and body parts in forensic pathology and reconstructing heavily damaged evidence acquired from crime scene investigations.
More recently, the use of 3D printing technology for artistic expression has been suggested.Artists have been using 3D printers in various ways.
3D printing technology is currently being studied by biotechnology firms and academia for possible use in tissue engineering applications where organs and body parts are built using inkjet techniques. Layers of living cells are deposited onto a gel medium and slowly built up to form three dimensional structures. Several terms have been used to refer to this field of research: organ printing, bio-printing, and computer-aided tissue engineering, among others.3D printing can produce a personalized hip replacement in one pass, with the ball permanently inside the socket, and even at current printing resolutions the unit will not require polishing.
The use of 3D scanning technologies allow the replication of real objects without the use of molding techniques, that in many cases can be more expensive, more difficult, or too invasive to be performed; particularly with precious or delicate cultural heritage artifacts where the direct contact of the molding substances could harm the surface of the original object.
There have been several, often related, efforts to develop 3D printers suitable for desktop use, and to make this technology available at price points affordable to many individual end-users. Much of this work was driven by and targeted to DIY/enthusiast/early adopter communities, with links to both the academic and hackercommunities.
RepRap is a project that aims to produce a FOSS 3D printer, whose full specifications are released under the GNU General Public License, that can copy some part of itself (the printed parts). As of November 2010, the RepRap can only print plastic parts. Research is under way to enable the device to print circuit boards too, as well as metal parts. The average price of a RepRap printer is about 400 euro.
3D printer kits can also be obtained. Kits exist for Thing-O-Matic, Ultimaker, and Shapercube 3D printers.Prices of these printers are about 1500 euro.

About Inverter

An inverter is an electrical device that converts direct current to alternating current; the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.Solid-state inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are commonly used to supply AC power from DC sources such as solar panels or batteries.

The inverter performs the opposite function of a rectifier.

Basic designs

In one simple inverter circuit, DC power is connected to a transformer through the centre tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit..
The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and an electromagnet pulls the movable contact to the opposite stationary contact. The current in the electromagnet is interrupted by the action of the switch so that the switch continually switches rapidly back and forth. This type of electromechanical inverter switch, called a vibrator or buzzer, was once used in vacuum tube automobile radios. A similar mechanism has been used in door bells, buzzers and tattoo guns.
As they became available with adequate power ratings, transistors and various other types of semiconductor switches have been incorporated into inverter circuit designs.

About Touchscreen

A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. Touchscreens are common in devices such as all-in-one computers, tablet computers, and smartphones.Surface acoustic wave  technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing. Surface wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen


Infrared:-
An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any input including a finger, gloved finger, stylus or pen. It is generally used in outdoor applications and point of sale systems which can't rely on a conductor to activate the touchscreen. Unlike capacitive touchscreens, infrared touchscreens do not require any patterning on the glass which increases durability and optical clarity of the overall system.

Its Construction:-
There are several principal ways to build a touchscreen. The key goals are to recognize one or more fingers touching a display, to interpret the command that this represents, and to communicate the command to the appropriate application.
In the most popular techniques, the capacitive or resistive approach, there are typically four layers;

1. Top polyester coated with a transparent metallic conductive coating on the bottom
2. Adhesive spacer
3. Glass layer coated with a transparent metallic conductive coating on the top
4. Adhesive layer on the backside of the glass for mounting.

When a user touches the surface, the system records the change in the electrical current that flows through the display.
Dispersive-signal technology which 3M created in 2002, measures the piezoelectric effect — the voltage generated when mechanical force is applied to a material — that occurs chemically when a strengthened glass substrate is touched.
There are two infrared-based approaches. In one, an array of sensors detects a finger touching or almost touching the display, thereby interrupting light beams projected over the screen. In the other, bottom-mounted infrared cameras record screen touches.

Fingerprints:-
Touchscreens can suffer from the problem of fingerprints on the display. This can be mitigated by the use of materials with optical coatings designed to reduce the visible effects of fingerprint oils, or oleophobic coatings as used in the iPhone 3G S, which lessen the actual amount of oil residue, or by reducing skin contact by using a fingernail or stylus.

Working Principle of LED (Light Emitting Diode)

A light-emitting diode (LED) is a semiconductor light source.LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.
The LED consists of a chip of semiconducting material doped with impurities to create a p-n junction. As in other diodes, current flows easily from the p-side, or anode, to the n-side, or cathode, but not in the reverse direction. Charge-carriers—electrons and holes—flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon.
The wavelength of the light emitted, and thus its color depends on the band gap energy of the materials forming the p-n junction. In silicon or germanium diodes, the electrons and holes recombine by a non-radiative transition which produces no optical emission, because these are indirect band gap materials. The materials used for the LED have a direct band gap with energies corresponding to near-infrared, visible or near-ultraviolet light.
LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have enabled making devices with ever-shorter wavelengths, emitting light in a variety of colors.
LEDs are usually built on an n-type substrate, with an electrode attached to the p-type layer deposited on its surface. P-type substrates, while less common, occur as well. Many commercial LEDs, especially GaN/InGaN, also use sapphire substrate.
Most materials used for LED production have very high refractive indices. This means that much light will be reflected back into the material at the material/air surface interface. Thus, light extraction in LEDs is an important aspect of LED production, subject to much research and development.

Working Principle of Plasma T.V

 

A plasma display panel  is a type of flat panel display common to large TV displays 30 inches or larger. They are called "plasma" displays because the technology utilizes small cells containing electrically charged ionized gases, or what are in essence chambers more commonly known as fluorescent lamps.
A panel typically has millions of tiny cells in compartmentalized space between two panels of glass. These compartments, or "bulbs" or "cells", hold a mixture of noble gases and a minuscule amount of mercury. Just as in the fluorescent lamps over an office desk, when the mercury is vaporized and a voltage is applied across the cell, the gas in the cells form a plasma. With flow of electricity, some of the electrons strike mercury particles as the electrons move through the plasma, momentarily increasing the energy level of the molecule until the excess energy is shed. Mercury sheds the energy as ultraviolet (UV) photons. The UV photons then strike phosphor that is painted on the inside of the cell. When the UV photon strikes a phosphor molecule, it momentarily raises the energy level of an outer orbit electron in the phosphor molecule, moving the electron from a stable to an unstable state; the electron then sheds the excess energy as a photon at a lower energy level than UV light; the lower energy photons are mostly in the infrared range but about 40% are in the visible light range. Thus the input energy is shed as mostly heat (infrared) but also as visible light. Depending on the phosphors used, different colors of visible light can be achieved. Each pixel in a plasma display is made up of three cells comprising the primary colors of visible light. Varying the voltage of the signals to the cells thus allows different perceived colors.
A plasma display panel is an array of hundreds of thousands of small, luminous cells positioned between two plates of glass. Each cell is essentially a tiny neon lamp filled with rarefied neon, xenon, and other inert gases; the cells are luminous when they are electrified through "electrodes".
The long electrodes are stripes of electrically conducting material that also lie between the glass plates, in front of and behind the cells. The "address electrodes" sit behind the cells, along the rear glass plate, and can be opaque. The transparent display electrodes are mounted in front of the cell, along the front glass plate. As can be seen in the illustration, the electrodes are covered by an insulating protective layer.Control circuitry charges the electrodes that cross paths at a cell, creating a voltage difference between front and back. Some of the atoms in the gas of a cell then lose electrons and become ionized, which creates an electrically conducting plasma of atoms, free electrons, and ions. The collisions of the flowing electrons in the plasma with the inert gas atoms leads to light emission; such light-emitting plasmas are known as glow discharges.
In a monochrome plasma panel, the gas is usually mostly neon, and the color is the characteristic orange of a neon-filled lamp.Once a glow discharge has been initiated in a cell, it can be maintained by applying a low-level voltage between all the horizontal and vertical electrodes–even after the ionizing voltage is removed. To erase a cell all voltage is removed from a pair of electrodes. This type of panel has inherent memory. A small amount of nitrogen is added to the neon to increase hysteresis.
In color panels, the back of each cell is coated with a phosphor. The ultraviolet photons emitted by the plasma excite these phosphors, which give off visible light with colors determined by the phosphor materials. This aspect is comparable to fluorescent lamps and to the neon signs that use colored phosphors.
Every pixel is made up of three separate subpixel cells, each with different colored phosphors. One subpixel has a red light phosphor, one subpixel has a green light phosphor and one subpixel has a blue light phosphor. These colors blend together to create the overall color of the pixel, the same as a triad of a shadow mask CRT or color LCD. Plasma panels use pulse-width modulation (PWM) to control brightness: by varying the pulses of current flowing through the different cells thousands of times per second, the control system can increase or decrease the intensity of each subpixel color to create billions of different combinations of red, green and blue. In this way, the control system can produce most of the visible colors. Plasma displays use the same phosphors as CRTs, which accounts for the extremely accurate color reproduction when viewing television or computer video images (which use an RGB color system designed for CRT display technology).
Plasma displays should not be confused with liquid crystal displays (LCDs), another lightweight flat-screen display using very different technology. LCDs may use one or two large fluorescent lamps as a backlight source, but the different colors are controlled by LCD units, which in effect behave as gates that allow or block the passage of light from the backlight to red, green, or blue paint on the front of the LCD panel.

About the History

In my thought,Google is the largest Search Engine in the World.Google began in March 1997 as a research project by Larry Page and Sergey Brin, Ph.D. students at Stanford working on the Stanford Digital Library Project . The SDLP's goal was “to develop the enabling technologies for a single, integrated and universal digital library." and was funded through the National Science Foundation among other federal agencies.His supervisor Terry Winograd encouraged him to pick this idea (which Page later recalled as "the best advice I ever got"and Page focused on the problem of finding out which web pages link to a given page, considering the number and nature of such backlinks to be valuable information about that page.In his research project, nicknamed "BackRub", he was soon joined by Sergey Brin, a fellow Stanford Ph.D. student supported by a National Science Foundation Graduate Fellowship.Brin was already a close friend, whom Page had first met in the summer of 1995 in a group of potential new students which Brin had volunteered to show around the campus.Page's web crawler began exploring the web in March 1996, setting out from Page's own Stanford home page as its only starting point.To convert the backlink data that it gathered into a measure of importance for a given web page, Brin and Page developed the PageRank algorithm.
Originally the search engine used the Stanford website with the domain google.stanford.edu. The domain google.com was registered on September 15, 1997. They formally incorporated their company, Google Inc., on September 4, 1998 at a friend's garage in Menlo Park, California.
The name "Google" originated from a misspelling of "googol,"which refers to the number represented by a 1 followed by one-hundred zeros (although Enid Blyton used the phrase "Google Bun" in The Magic Faraway Tree (published 1941), The Folk of the Faraway Tree (published 1946),and called a clown character "Google" in Circus Days Again ,and there is also the Googleplex Star Thinker from Douglas Adams' The Hitchhiker's Guide to the Galaxy). Having found its way increasingly into everyday language, the verb, "google," was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning, "to use the Google search engine to obtain information on the Internet."The use of the term itself reflects their mission to organize a seemingly infinite amount of information on the web.
Google's declared code of conduct is "Don't be evil", a phrase which they went so far as to include in their prospectus for their 2004 IPO, noting, "We believe strongly that in the long term, we will be better served — as shareholders and in all other ways — by a company that does good things for the world even if we forgo some short term gains.

About Nokia 5800 Xpress Music

Nokia 5800 XpressMusic is a smartphone and portable entertainment device by Nokia.It was introduced on January 2008,and released on April 27, 2008.Code-named "Tube", it is the first touchscreen-equipped S60 device by Nokia, the version being s60v5. It's part of the XpressMusic series of phones, which emphasizes music and multimedia playback. The touchscreen features tactile feedback.
  On August 2009, Nokia announced a new variant named Nokia 5800 Navigation Edition. In addition to the normal Nokia 5800 it has the latest version of Ovi Maps pre-installed. It also comes with a car-charger and car-kit inside the box because the GPS decreases the battery life. Both the Nokia 5800 XpressMusic and the 5800 Navigation edition, however, have free lifetime navigation, due to the new version of Ovi maps.It is now available at nokia.com.
^{Its Firmware:}
From firmware version 20.0.012 onwards, the 5800's CPU clock was increased from 369 MHz to 434 MHz, matching the N97 specification.However, improved overall performance can be observed since firmware version 30.
On January 13, 2010, Nokia released a major firmware update, version 40.0.005. The update includes bug fixes, speed improvements and new features. The most visible are kinetic scrolling to all menus and an improved home screen that was first introduced on the Nokia 5530. This version update also saw the removal of alphanumeric keypad in landscape view during text input. This was replaced by a full QWERTY keyboard. The new home screen provides a contacts carousel, with up to 20 contacts and program shortcuts on screen at the same time. There is a change on option selecting in every menus, but hard to notice; if one selects and holds on that selection, it will be in white, but normal colours when selecting an option is still being red like in v20.
On April 19, 2010, firmware version 50.0.005 was released. This new major update brought some new features available in Nokia N97, such as an upgrade to the existing web browser to version 7.2 and full kinetic scrolling and auto-full screen while browsing the web; a new music player with mini-album art in the song list and the album list, initial letter filtering of track titles in the music player while scrolling using the scroll-bar. As a result, the search function was removed from the music player. A new application called Ovi Sync was installed and the Nokia Music Store received a revamped user interface and was renamed to "Ovi Music". In some regions, Quick Office 4.2.374 is integrated with full free license. Search application's icon was changed and a few more minor updates for better touch sensitivity and tweaks for faster operation of the phone are present. And a little update to the color, the option you select is in silver, but when hold an option, it is still being white like v40. There is also the new feature, one-touch dialling.
