Horace Smith and Daniel Baird Wesson Biography
Smith, born in Cheshire, Massachusetts, moved to Springfield at the age of four, and upon completing his public school education, joined his father working in the United States armory as an apprentice. Through his early career, heworked his own gun-manufacturing business, as well as producing pistols and tools for the manufacture of rifles for other companies. He patented an improvement on the breech-loading rifle in 1851, a year before he met Wesson through their work at Allen, Brown, and Luther rifle barrel manufacturers.
Wesson was born in Worcester, Massachusetts, and was the son of a farmer andmanufacturer of wooden plows. He attended public school until he was eighteenyears old, and then apprenticed himself to his eldest brother, a gunsmith. After his brother died, Wesson owned the business for a short time, then became employed by Allen, Brown, and Luther. In his off-hours, Wesson experimentedon an improved metallic cartridge, and in 1853, convinced Smith to go into business with him. The following year, the pair patented a pistol that used acartridge with powder and lubricant, and had a new repeating action, which became the basis for the famous Winchester rifle.
Smith retired from the business in 1855, when Wesson became superintendent ofthe Volcanic Arms Co., and they sold their patents to the company. Under Wesson, the Volcanic Arms Co. produced the self-primed metallic cartridge used throughout the Civil War. In 1857, the two men rejoined to produce the Smith & Wesson revolver. Manufactured with interchangeable parts, it used repeating action, metallic cartridges, and an open cylinder. It was the only one ofits type, and it became an enormous success. It was adopted by U.S. militaryauthorities and also secured foreign markets in European and South Americancountries, as well in China and Japan. In 1860 Smith & Wesson expanded their 25-member workforce to 600 and built a factory in Springfield, Massachusetts.
Smith and Wesson improved their inventions with patents of their own and those purchased from other inventors. In 1869, they bought a design by William C.Dodge that emptied shells from the gun. Wesson patented a safety revolver that prevented unintentional firing in 1887.
In 1883, Smith sold his interest in the company to Wesson and retired, involving himself in local business activities. Wesson took on his two sons as partners ten years later. Smith & Wesson is still one of the largest gun manufacturers in America.
Smith & Wesson
In 1852, partners Horace Smith and Daniel B. Wesson formed a company to produce a lever-action pistol nicknamed the Volcanic pistol. The company became known as the "Volcanic Repeating Arms Company"; financial difficulties caused it to come into the majority ownership of investor Oliver Winchester. Previously, in the late 1840s, Daniel Wesson's brother Edwin, of Hartford, Massachusetts, had manufactured revolvers under the name of Wesson & Leavitt. After Edwin Wesson's death, that firm continued under the supervision of Thomas Warner.
In 1856, the partners left the Volcanic Company to begin a new company and to manufacture a newly-designed revolver-and-cartridge combination. The timing of the founding of this new company proved quite opportune for the partners, since the onset of the American Civil War five years later produced a great demand for Smith & Wesson's products.
In 1964, the company passed from Wesson family control, and subsequently several conglomerates took control of it.
From 1987 to 2001 Tomkins PLC, a British company, owned Smith & Wesson.

Crystal
The word crystal is a loan from the ancient Greek word κρύσταλλος (krustallos), which had the same meaning, but according to the ancient understanding of crystal. At root it means anything congealed by freezing, such as ice. The word once referred particularly to quartz, or "rock crystal".
Most metals encountered in everyday life are polycrystals. Crystals are often symmetrically intergrown to form crystal twins.
The process of forming a crystalline structure from a fluid or from materials dissolved in the fluid is often referred to as crystallization. In the ancient example referenced by the root meaning of the word crystal, water being cooled undergoes a phase change from liquid to solid beginning with small ice crystals that grow until they fuse, forming a polycrystalline structure. The physical properties of the ice depend on the size and arrangement of the individual crystals, or grains, and the same may be said of metals solidifying from a molten state.
Which crystal structure the fluid will form depends on the chemistry of the fluid, the conditions under which it is being solidified, and also on the ambient pressure. While the cooling process usually results in the generation of a crystalline material, under certain conditions, the fluid may be frozen in a noncrystalline state. In most cases, this involves cooling the fluid so rapidly that atoms cannot travel to their lattice sites before they lose mobility. A noncrystalline material, which has no long-range order, is called an amorphous, vitreous, or glassy material. It is also often referred to as an amorphous solid, although there are distinct differences between solids and glasses: most notably, the process of forming a glass does not release the latent heat of fusion. For this reason, many scientists consider glassy materials to be viscous liquids rather than solids, although this is a controversial topic.
Crystalline structures occur in all classes of materials, with all types of chemical bonds. Almost all metal exists in a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, often with great difficulty. Ionically bonded crystals can form upon solidification of salts, either from a molten fluid or when it condenses from a solution. Covalently bonded crystals are also very common, notable examples being diamond, silica, and graphite. Polymer materials generally will form crystalline regions, but the lengths of the molecules usually prevent complete crystallization. Weak Van der Waals forces can also play a role in a crystal structure; for example, this type of bonding loosely holds together the hexagonal-patterned sheets in graphite.
Most crystalline materials have a variety of crystallographic defects. The types and structures of these defects can have a profound effect on the properties of the materials.

What is bluetooth?
What is 3G?
1GThe 1G period began in the late 1970s and lasted through the 1980s. These systems featured the first true mobile phone systems, known at first as "cellular mobile radio telephone." These networks used analog voice signaling, and were little more sophisticated than the repeater networks used by amateur radio operators.
2GThe 2G phase began in the 1990s and much of this technology is still in use. The 2G cell phone features digital voice encoding. Examples include CDMA and GSM. Since its inception, 2G technology has steadily improved, with increased bandwidth, packet routing, and the introduction of multimedia.
3G includes capabilities and features such as:
Enhanced multimedia (voice, data, video, and remote control).
Usability on all popular modes (cellular telephone, e-mail, paging, fax, videoconferencing, and Web browsing).
Broad bandwidth and high speed (upwards of 2 Mbps).
Roaming capability throughout Europe, Japan, and North America.
While 3G is generally considered applicable mainly to mobile wireless, it is also relevant to fixed wireless and portable wireless. A 3G system should be operational from any location on, or over, the earth's surface, including use in homes, businesses, government offices, medical establishments, the military, personal and commercial land vehicles, private and commercial watercraft and marine craft, private and commercial aircraft (except where passenger use restrictions apply), portable (pedestrians, hikers, cyclists, campers), and space stations and spacecraft.
3G offers the potential to keep people connected at all times and in all places. Researchers, engineers, and marketers are faced with the challenge of accurately predicting how much technology consumers will actually be willing to pay for. Another challenge faced by 3G services is competition from other high-speed wireless technologies, especially mobile WiMAX, and ability to roam between different kinds of wireless networks.
The current status of mobile wireless communications, as of July 2007, is a mix of 2nd and 3rd generation technologies.
History of Vodafone
At 31 March 2008 Vodafone had 260 million proportionate customers in 25 markets across 5 continents. ("Proportionate customers" means, for example, that if Vodafone has a 30% stake in a business with a million customers, that is counted as 300,000). On this measure it is the second largest mobile telecom group in the world behind China Mobile. The eight markets where it has more than ten million proportionate customers are the United Kingdom, Germany, India, Italy, Spain, Turkey, Egypt and the United States. In the U.S., these customers come via its minority stake in Verizon Wireless, and in the other seven markets Vodafone has majority-controlled subsidiaries.
In 1982 Racal Electronics plc's subsidiary Racal Strategic Radio Ltd. won one of two UK cellular telephone network licences. The network, known as Racal Vodafone was 80% owned by Racal, with Millicom and the Hambros Technology Trust owning 15% and 5% respectively. vodafone was launched on 1 January 1985. Racal Strategic Radio was renamed Racal Telecommunications Group Limited in 1985. On 29 December 1986 Racal Electronics bought out the minority shareholders of vodafone for GB£110 million.
In September 1988 the company was again renamed Racal Telecom and on 26 October 1988 Racal Electronics floated 20% of the company. The flotation valued Racal Telecom at GB£1.7 billion. On 16 September 1991 Racal Telecom was demerged from Racal Electronics as Vodafone Group.
In July 1996 Vodafone acquired the two thirds of Talkland it did not already own for £30.6 million. On 19 November 1996, in a defensive move, Vodafone purchased Peoples Phone for £77 million, a 181 store chain whose customers were overwhelmingly using Vodafone's network. In a similar move the company acquired the 80% of Astec Communications that it did not own, a service provider with 21 stores.
In 1997 Vodafone introduced its Speechmark logo, as it is a quotation mark in a circle; the O's in the Vodafone logotype are opening and closing quotation marks, suggesting conversation.
On 29 June 1999 Vodafone completed its purchase of AirTouch Communications, Inc. and changed its name to Vodafone Airtouch plc. Trading of the new company commenced on 30 June 1999. To approve the merger, Vodafone sold its 17.2% stake in E-Plus Mobilfunk. The acquisition gave Vodafone a 35% share of Mannesmann, owner of the largest German mobile network.
On 21 September 1999 Vodafone agreed to merge its U.S. wireless assets with those of Bell Atlantic Corp to form Verizon Wireless. The merger was completed on 4 April 2000.
In November 1999 Vodafone made an unsolicited bid for Mannesmann, which was rejected. Vodafone's interest in Mannesmann had been increased by the latter's purchase of Orange, the UK mobile operator. Chris Gent would later say Mannesmann's move into the UK broke a "gentleman's agreement" not to compete in each other's home territory. The hostile takeover provoked strong protest in Germany and a "titanic struggle" which saw Mannesmann resist Vodafone's efforts. However, on 3 February 2000 the Mannesmann board agreed to an increased offer of £112bn, then the largest corporate merger ever. The EU approved the merger in April 2000. The conglomerate was subsequently broken up and all manufacturing related operations sold off.
On 28 July 2000 the Company reverted to its former name, Vodafone Group Plc. In April 2001 the first 3G voice call was made on Vodafone United Kingdom's 3G network.
In 2001 the Company took over Eircell, then part of eircom in Ireland, and rebranded it as Vodafone Ireland. It then went on to acquire Japan's third-largest mobile operator J-Phone, which had introduced camera phones first in Japan.
On 17 December 2001 Vodaphone introduced the concept of "Partner Networks" by signing TDC Mobil of Denmark. The new concept involved the introduction of Vodafone international services to the local market, without the need of investment by Vodafone. The concept would be used to extend the Vodafone brand and services into markets where it does not have stakes in local operators. Vodafone services would be marketed under the dual-brand scheme, where the Vodafone brand is added at the end of the local brand. (i.e., TDC Mobil-Vodafone etc.)
In February 2002 Finland was added into the mobile community, as Radiolinja is signed as a Partner Network. Radiolinja later changed its named to Elisa. Later that year the Company rebranded Japan's J-sky mobile internet service as Vodafone live! and on 3 December 2002 the Vodafone brand was introduced in the Estonian market with signing of a Partner Network Agreement with Radiolinja (Eesti). Radiolinja (Eesti) later changed its name to Elisa.
On 7 January 2003 the Company signed a group-wide Partner agreement with mobilkom Austria. As a result, Austria, Croatia, and Slovenia were added to the community. In April 2003 Og Vodafone was introduced in the Icelandic market and in May 2003 Vodafone Italy (Omnitel Pronto-Italia) was rebranded Vodafone Italy. On 21 July 2003 Lithuania was added to the community, with the signing of a Partner Network agreement with Bitė.
In February 2004 Vodafone signed a Partner Network Agreement with Luxembourg's LuxGSM and a Partner Network Agreement with Cyta of Cyprus. Cyta agreed to rename its mobile phone operations to Cytamobile-Vodafone. In April 2004 the Company purchased Singlepoint airtime provider from John Caudwell (Caudwell Group) and approx 1.5million customers onto its base for £405million, adding sites in Stoke on Trent (England) to existing sites in Newbury (HQ), Birmingham, Warrington and Banbury. In November 2004 Vodafone introduced 3G services into Europe.
In June 2005 the Company increased its participation in Romania's Connex to 99% and also bought the Czech mobile operator Oskar. On 1 July 2005 Oskar of the Czech Republic was rebranded as Oskar-Vodafone. Later that year on 17 October 2005 Vodafone Portugal launched a revised logo, using new text designed by Dalton Maag, and a 3D version of the Speechmark logo, but still retaining a red background and white writing (or vice versa). Also, various operating companies started to drop the use of the SIM card pattern in the company logo. (The rebranding of Oskar-Vodafone and Connex-Vodafone also does not use the SIM card pattern.) A custom typeface by Dalton Maag (based on their font family InterFace) formed part of the new identity.
On 28 October 2005 Connex in Romania was rebranded as Connex-Vodafone and on 31 October 2005 the Company reached an agreement to sell Vodafone Sweden to Telenor for approximately €1 billion. After the sale, Vodafone Sweden became a Partner Network. In December 2005 Vodafone won an auction to buy Turkey's second-largest mobile phone company, Telsim, for $4.5 billion. In December 2005 Vodafone Spain became the second member of the group to adopt the revised logo: it was phased in over the following six months in other countries.
In 2006 the Company rebranded its Stoke-on-Trent site as Stoke Premier Centre, a centre of expertise for the company dealing with Customer Care for its higher value customers, technical support, sales and credit control. All cancellations and upgrades started to be dealt with by this call centre. On 5 January 2006 Vodafone announced the completion of the sale of Vodafone Sweden to Telenor. On February 2006 the Company closed its Birmingham Call Centre. In 1 February 2006 Oskar Vodafone became Vodafone Czech Republic, adopting the revised logo and on 22 February 2006 the Company announced that it was extending its footprint to Bulgaria with the signing of Partner Network Agreement with Mobiltel, which is part of mobilkom Austria group.
On 12 March 2006 former chief, Sir Christopher Gent, who was appointed the honorary post Chairman for Life in 2003, quits following rumours of boardroom rifts. In April 2006 the Company announced that it has signed an extension to its Partner Network Agreement with BITE Group, enabling its Latvian subsidiary "BITE Latvija" to become the latest member of Vodafone's global partner community. Also in April 2006 Vodafone Sweden changed its name to Telenor Sverige AB and Connex-Vodafone became Vodafone Romania, also adopting the new logo. On 30 May 2006 Vodafone announced the biggest loss in British corporate history (£14.9 billion) and plans to cut 400 jobs; it reported one-off costs of £23.5 billion due to the revaluation of its Mannesmann subsidiary. On 24 July 2006 the respected head of Vodafone Europe, Bill Morrow, quit unexpectedly and on 25 August 2006 the Company announced the sale of its 25% stake in Belgium's Proximus for €2 billion. After the deal, Proximus was still part of the community as a Partner Network. On 5 October 2006 Vodafone announced the first single brand partnership with Og Vodafone which would operate under the name Vodafone Iceland and on 19 December 2006 the Company announced the sale of its 25% stake in Switzerland's Swisscom for CHF4.25 billion (£1.8 billion). After the deal, Swisscom would still be part of the community as a Partner Network. Finally in December 2006 the Company completed the acquisition of Aspective, an enterprise applications systems integrator in the UK, signaling Vodafone's intent to grow a significiant presence and revenues in the ICT marketplace.
Early in January 2007 Telsim in Turkey adopted Vodafone dual branding as Telsim Vodafone and on 1 April 2007 Telsim Vodafone Turkey droped its original brand and became Vodafone Turkey. On 1 May 2007 Vodafone added Jersey and Guernsey to the community, as Airtel was signed as Partner Network in both crown dependencies. In June 2007 the Vodafone live! mobile Internet portal in the UK was relaunched. Front page was now charged for and previously "bundled" data allowance was removed from existing contract terms. All users were given access to the "full" web rather than a Walled Garden and Vodafone became the first mobile network to focus an entire media campaign on its newly launched mobile Internet portal in the UK. On 1 August 2007 Vodafone Portugal launched Vodafone Messenger, a service with Windows Live Messenger and Yahoo! Messenger.
On 17 April 2008 Vodafone extended its footprint to Serbia as Vip mobile was added to the community as a Partner Network and on 20 May 2008 the Company added VIP Operator as a Partner Network thereby extending the global footprint to Macedonia. In May 2008 Kall of the Faroe Islands rebranded as Vodafone Faroe Islands.

History of iPhone
The history of the iPhone began with Steve Jobs' direction that Apple engineers investigate touch-screens. At the time he had been considering having Apple work on tablet PCs. Many have noted the device's similarities to Apple's previous touch-screen portable device, the Newton MessagePad. Like the Newton, the iPhone is nearly all screen. Its form factor is credited to Apple's head of design, Jonathan Ive.
Comments made by Jobs in April 2003 at the "D: All Things Digital" executive conference expressed his belief that tablet PCs and traditional PDAs were not good choices as high-demand markets for Apple to enter, despite many requests made to him that Apple create another PDA. He did believe that cell phones were going to become important devices for portable information access, and that what cell phones needed to have was excellent synchronization software. At the time, instead of focusing on a follow-up to their Newton PDA, Jobs had Apple put its energies into the iPod, and the iTunes software (which can be used to synchronize content with iPod devices), released January 2001. On September 7, 2005, Apple and Motorola released the ROKR E1, the first mobile phone to use iTunes. Jobs was unhappy with the ROKR, feeling that having to compromise with a non-Apple designer (Motorola) prevented Apple from designing the phone they wanted to make. In September 2006, Apple discontinued support for the ROKR and released a version of iTunes that included references to an as-yet unknown mobile phone that could display pictures and video. On January 9, 2007, Jobs announced the iPhone at the Macworld convention, receiving substantial media attention, and on June 11, 2007 announced at the Apple's Worldwide Developer's Conference that the iPhone would support third-party applications using the Safari engine on the device. Third-parties would create the Web 2.0 applications and users would access them via the internet. Such applications appeared even before the release of the iPhone; the first being "OneTrip", a program meant to keep track of the user's shopping list. On June 29, 2007, Apple released version 7.3 of iTunes to coincide with the release of the iPhone. This release contains support for iPhone service activation and syncing.
According to The Wall Street Journal, the iPhone is manufactured on contract in the Shenzhen factory of the Taiwanese company Hon Hai.
History of LG
With headquarters in the LG Twin Towers on Yeouido, Seoul, LG Electronics is the flagship company of LG Group, one of the largest chaebols.
The LG Group was a merger of two Korean companies, Lucky and GoldStar, from which the abbreviation of LG was derived. The current "Life's Good" slogan is a backronym. Before the corporate name change to LG, household products were sold under the brand name of Lucky, while electronic products were sold under the brand name of GoldStar (Hangul:금성). The GoldStar brand is still perceived as a discount brand. ' In 1994 Goldstar gained sponsorship from The 3DO Company to make the first 3DO Interactive multiplayer. It was very pricey, but is examined to be the best out of all of the 3DO Systems.
In 1995, GoldStar was renamed LG Electronics, and acquired Zenith Electronics of the United States.
History of Sony Ericsson
The company's global management is based in Hammersmith, London, and it has research & development teams in Sweden, Japan, China, Germany, the United States, India, Pakistan and the United Kingdom.
Sony Ericsson has, as of July 18, 2008, approximately 9,400 employees and 2,500 contractors worldwide. The company's current President is as of November 1 Hideki Komiyama (小宮山英樹), who has replaced Miles Flint, and the Corporate Executive Vice President is Anders Runevad.
History of Samsung
In 1938 the Samsung's founder Byung-Chull Lee set up a trade export company in Korea, selling fish, vegetables, and fruit to China. Within a decade Samusng had flour mills and confectionary machines and became a co-operation in 1951. Humble beginnings.
1987 founder and chairman, Byung-Chull Lee passed away and Kun-Hee Lee took over as chairman. In the 1990's Samsung began to expand globally building factories in the US, Britain, Germany, Thailand, Mexico, Spain and China until 1997.

24
24 is an Emmy and Golden Globe award-winning American action drama television series. Broadcast by Fox Network in the USA and syndicated worldwide, the show first aired on November 6, 2001, with an initial thirteen episodes. The first six seasons were all centered around the fictional Los Angeles branch of the U.S. government Counter Terrorist Unit (CTU).
24 is presented in real time, with each season depicting a 24-hour period in the life of Jack Bauer, who works with the U.S. government as it fights threats on U.S. soil. Bauer is often in the field for the fictional Los Angeles Counter Terrorist Unit (CTU) as they try to safeguard the nation from terrorist threats. The show also follows the actions of other CTU agents, government officials and terrorists associated with the plot. The first six seasons of the show were all based in Los Angeles and nearby locations — both real and fictional — in California, although occasionally other locations have been featured as well — most notably, Washington, D.C., where a significant portion of the action took place during the fourth and sixth seasons. Promotional materials for the seventh season have already established that, departing from tradition, it will be set primarily in Washington, D.C.
After leading actor Kiefer Sutherland won a Golden Globe for his role in the first 10 episodes, the ratings of the show increased, leading FOX to order the second half of the season. There have been six seasons of 24 produced. On May 15, 2007, it was confirmed that FOX has ordered seventh and eighth seasons. A motion picture based on the show has been written and was scheduled to be filmed in 2007 for a 2008 release but plans for production were put on hold to focus on the TV series.
The seventh season, originally scheduled to premiere on January 13, 2008, was initially postponed in the wake of the 2007-08 Writers Guild of America strike to ensure a non stop season, a trademark of the show since the start of its fourth season in January 2005. It is now officially postponed until January 2009.
To help offset the strike-induced delay, 24 will return on Sunday, November 23, 2008 with a two-hour prequel (titled 24: Exile) that will take place almost a year after day six and will "set up the story that launches season seven".
