invention of telivision set

The televison set was invented by not one person but a group of numerous personnel. The principal idea was based on photoconductivity of the element selenium, founded by Willoughby Smith in 1873. All televisions make use of an image which is scanned to produce a representation time signal, which is then reversed and decoded by the human eye.

On 26 January 1926, John Logie Baird demonstrated the first public television, which transmitted live moving images. Several months later, 3 July 1928, Baird demonstrated the first colour television. In 1923, Charles Francis Jenkindemonstrated his own version of a primitive television set.

Strangely enough, colour televisions were patented before black and white televisions were even fully functional. The reason being the fact that inventors knew this was possible and each wanted to claim the idea as their own.

Camarena invented the "Chromoscopic adapter for television equipment", which was a basic transmission mechanism for colour television. It was he who received the patent for colour televisions initially in September 15, 1942 adapted in 1960 and further in 1962.

Exclusively electronic systems relied on research by both Philo Taylor Farnsworth and Vladimir Zworykin, in order to mass distribute television programming evident in the modern world.

The first regular transmissions originated in Germany, 1935, using 180 scan lines to deliver the picture. 2 years later these lines increased to 441 in an effort to improve quality.

The first launch outwith Germany was England, 1936, from Alexandria Place. Baird's system was established but only spanned 4 months, since it contained 240 lines, whereas its successor EMI-Marconi's System A contained 405 lines and delivered a greater quality of picture.

It took almost 20 years for the television to be commonplace in an American household, as in the mid 1950's programming was typical in the majority of homes across the world.

INVENTION OF THE TELEPHONE

One of the most important and revolutionary inventions which impacts greatly upon modern day communication is the invention of the telephone. The idea behind the telephone is simple, a system which converts sound into a series ofelectrical impulses of differing frequencies, and then reverses this procedure to re-create the sound, typically a human voice. Sounds simple enough, but it took many years and an array of different inventors to finally succeed with thetechnology.

As early as 1831, Michael Faraday proved that vibrations of metal could be converted into electrical impulses. This was the basic principle of the telephone, but no one made use of such technology until 1861, when German inventor, Johann Reis, successfully built an apparatus that converted sound to electricity and back again. The apparatus had many flaws, incapable of transmitting many frequencies and therefore was never fully developed.

This idea was elaborated on by two men in the United States, who simultaneously began experimenting and creating what would be known as the telephone. ElishaGray and Alexander Graham Bell (a Scottish inventor), both worked hard to produce the equipment, and amazingly both filed for a patent within hours of one another, Bell beating his rival by merely two hours on February 14th, 1876.

Despite Gray building the initial diaphragm / electromagnetic receiver two years prior, he was unable to produce a working version of his transmitter until after Bell. Bell worked effortlessly, whereas Gray became disheartened by the exhausting invention process.

The first comprehensible telephone conversation was said to have taken place between Bell and his assistant, who was sitting in another room. Bell said, "Come here, Watson, I want you" which Watson successfully heard via the receiver and the invention of the telephone was complete. The Bell Telephone Company (AT&T) was soon established and grew to be the largest telephone company in existence.

The following year, in 1877, the first telephone system was put in place in Hartford, Connecticut, whilst the first exchange which linked two cities, was established between both Boston and New York in 1883. London hosted the first exchange put into practice outside the United States in 1879. The system however proved time consuming, as the exchange was controlled by a large switchboard with a number of operators working manually to divert the calls.

The first automatic exchange was patented by Almon Strowger in 1891 and instilled in 1892, although manual switchboards remained in place until the mid-twentieth century. In 1889, William Gray invented the coin operated telephone, whereas the first rotary dial telephone was produced by Frenchman, Antoine Barnay, in 1923.

The Bell Telephone Company later developed the mobile telephone which was used by New York police cars in 1924. The first commercial mobile service was created in 1946, in St Louis, Missouri but it did not become commonplace until a following four decades.

Touch tone systems, which used sound tones rather than electrical pulses, were installed in 1941, however the need for central switching made the idea too expensive, yet Bell's company were curious as to the potential of touch tone employment. As electrical circuitry prices fell, the touch tone systems could finally be deployed in common households, which occurred in 1962.

AT&T began experimentation with cells within mobile technology, primarily based on hexagonal geographical regions. As the caller moved from one cell to another, the communication link would remain intact, by automatically switching to the new cell without any form of disruption. This foundation for mobile phone technologywas put into place in the United States in 1983.

The invention of the telephone is a hot topic within the inventor circle, and the recognised inventor is somewhat sketchy. Many believe it to be Alexander Graham Bell, whereas others believe it to be Antonio Meucci, Philip Reis or Elisha Gray.

invention of light bulb

INVENTION OF THE LIGHT BULB

he very first electric light was invented as early as 1800 by English inventor, Humphry Davy. Through various experimentations with electricity, he invented a basic electric battery, soon followed by electric light once he realised that carbon glowed, producing light when connected to the battery. This reaction is called an electric arc.

In 1860, Sir Joseph Wilson Swan set about attempting to develop a practical, long-lasting form if electric light. It was he who realised that carbon paper filament worked well, however did burn up relatively quickly. In 1878, his new lamp inventions were showcased in Newcastle, England.

1877 saw American Charles Francis Brush develop a series of carbon arcs in order to illuminate a public square in Ohio, USA. A few streets, some large office buildings and some stores all utilised electric lights, but the extent of usage was not at all common.

Typically credited as the 'inventor of the light bulb', Thomas Alva Edisonexperimented with thousands upon thousands of alternative filaments to find the best material for a long-lasting, high glow solution. 1879 was the year Edison finally realised that a carbon filament within an oxygen-free bulb glowed, but would not burn up for approximately 40 hours. Later, Edison invented a bulb that would not expire for over 1500 hours.

Lewis Howard Latimer improved upon Edison's bulb with a new carbon filament which he patented in 1881. Latimer was part of Edison's research team, termed "Edison's Pioneers", and in 1882 began to manufacture and distribute his own carbon filaments.

At the turn of the century, in 1903, Willis R. Whitney introduced a 'fix' to the light bulb, so that the inside of the bulb would not darken as the filament began to glow, thus producing more vivid and bright light. William David Coolidge then invented a tungsten version of the traditional filament, which lasted longer than any other filament. This incandescent light bulb revolutionised the way in which we live today.

MINI GOLF

MINI GOLF ARCADE GAME

Hammacher Schlemmer have produced a realistic golf video arcade game. The machine offers the user the best experience in miniature golf, and is similar to the machines found in popular arcade venues. The machine utilises real golf balls and real golf putters, whilst the courses are disaplyed virtually on screen, via the 32-inch LCD display. The game allows up to four players to participate at any one time, with two courses to choose from, the casino based Las Vegas course as well as the tiki torch orinted Paradise Island.

Shot controls include the ability to adjust the view, by panning left and right, and also the option to view from overhead, or directly behind the ball. Options which will allow you to plan the best route to the hall. As you make contact with the ball, and it approaches the screen, the machine calculates both the trajectory and position of the ball, with sound emitting from a trio of speakers.

The miniature golf arcade game looks brilliant, but the $6,900 price tag will be enough to deter most potential buyers. Also, it would have been nice to see a few more courses, as with only two courses, we're sure each shot can be mastered relatively quickly.


Everything about the Video Arcade Miniature Golf Game looks inviting except the hefty price of $6,900.

GP2X WIZ MAME AMIGA

GP2X WIZ MAME AMIGA CONSOLE EMULATOR

Time to re-live those old game classics on a modern day handheld, portable games console. What a fantastic Christmas gift this would make! (I've actually bought one for myb younger brother)

Normally this is the space where we would make some clever jokes and tell you why you might like to purchase this fine product. But in the case of this amazing GP2X Wiz pocket size gaming system we're cutting straight to the chase. If you are into retro gaming and have paid your rent this month you NEED to buy the GP2X Wiz now... like immediately... we're not joking. Because no where else will you find a handheld gaming system with emulators for so many game systems, computer platforms and consoles. Incredible MAME emulation allows you to run all your favorite arcade video game classics, even vector games. Amiga game emulation is rock solid. You can run Atari ST games, Commodore 64, NES, SNES, Gameboy, Gameboy Advance, NeoGeo, Flash Games and more too numerous to mention. Of course you'll need to find yourself some game roms... but we have a feeling that's no problem for you and Google.

The Wiz can do a host of other useful things besides gaming. It can play video files including MPEG4, Xvid and DIVX. You get a built in e-book reader, calendar, voice recorder... etc... you know the drill. 1GB of storage is built-in and you can expand on this with the SD (SDHC) card slot. The high-res touchscreen makes navigation easy and the gaming controls feature a d-pad on the left with buttons/d-pad on the right and two shoulder buttons on the top. It's plenty good for anything a retro game can dish out. There is an active development community for the GP2X Wiz and with a respectable ARM9 533MHz Processor overclockable to 800Mhz you've got plenty of power to play with if you're interested to write your own applications.

Important Note
The Wiz does not come with any emulator software or game roms pre-installed.Out of the box you can play some built in Flash games, but that's it. You'll need to download the freeware emulator for the console or computer system you want to emulate. Then you'll need to unzip the emulator software, and copy it to an SD card along with some game roms you've downloaded. Then start-up the Wiz, go into the "launcher" option and run the emulator. Inside the emulator you'll choose the rom you want to load and then the game can begin. Each emulator software interface is a bit different and most give you the option to overclock the Wiz to get the best performance. Remember you are running emulator software... most games work perfectly, but some may run slow or be glitchy. You may have to configure the controls to work well with the game you want to play. Documentation is not always the best, so you might need to put in a bit of effort to figure things out. If any of this scares you, then you may want to reconsider your purchase.

Here is a great site where you can download all the emulators available for the Wiz as well as other homebrew software. Please take a look at this before you buy.
