9 INVENTIONS OF THOMAS EDISON

Thomas Alva better known as Thomas Edison was born on February 11, 1847 in the city of Milan, Ohio. Was a US businessman who developed many important devices of great interest industrial.Moreu in West Orange, New Jersey on October 18, 1931 after 84 years.

1.Carbon microphone

There is a doubt between who really invented the telephone, if Graham Bell or Antonio Meucci, but one thing is certain: the carbon microphone was invented between 1877 and 1878 by Thomas Edison who gave more efficiency to the project. The device had a system to convert sound into an electrical signal, allowing the voice to be transmitted over long distances.

Edison disputed the authorship of his patent with another inventor, the German-American Emile Berliner, but the federal court of the United States assured him the authorship of the project. So even the audio pickup modern smartphone you use today has the ancestor Thomas Edison carbon microphone.

2.Stencil electric pen

Markings and drawings on the skin are common things in the history of various human societies, in various epochs of humanity. Currently, this is done with modern machines scratching the skin in a precise and competent, but you may not know it began 137 years precisely with Thomas Edison.

The US has developed a pen drilling that at first was not made to draw on the human skin. This was thought later in 1891 by an inventor named Samuel O'Reilly, who made some modifications to the creation of Edison and added an ink reservoir.

3.Vacuum packaging

In 1881, Edison patented a system of preserving fruit with vacuum technology which was to pack the product in a jar. More than a century later, the system has evolved considerably and the basic idea is still applied in vacuum packaging that you find in any supermarket.

Foods such as meat, fruit, vegetables, coffee and yerba mate are some of the items commonly found vacuum packed. This ensures germ-free food and bacteria and also assures durability to the taste of the product.

4.Electrographic vote recorder

Our electronic voting and other digital voting systems have a common ancestor electrographic vote recorder Thomas Edison patented in 1869, when he was only 22. This invention, which was his first patent, was connected to the desk clerk, and the voter could move one type of metal to mark one of the two columns ("yes" or "no") in each candidate.

The electrical signal was sent to the clerk table and in contact with the chemicals, recorded the vote. Decades and decades later, the system has been analog and is now electronic, with methods that theoretically guarantee the inviolability of the system and enough speed the counting of votes.

5.Rubber wheels

The wheel is probably the most revolutionary human inventions, but before Thomas Edison nobody had recorded intended to cover them rubber. In his time, the vehicles used wooden wheels without any cover, which face it, causing serious risks to passenger safety.

Edison then had the idea to coat the wooden wheels with rubber, giving the kickoff of something critical for just about any and every vehicle fitted with wheels these days.

6.Incandescent light bulb

In 1880, after almost a century of research, finally the light bulb long-term was marketed. The first discovery of its kind had been recorded in 1802. In all, 22 scientists helped in improving the contraption, but it was the American inventor Thomas Alva Edison who came closest of today's lamp. Responsible for inventions in 1093 - for example, the wireless radio and the gramophone - Edison perfected models of lamps that had already been studied and composed a device with thin carbon filament high vacuum, which lasted longer and had better quality . After receiving the patent, his company, Edison Electric Light Company, started selling the bulbs in the United States.

7.Movie camera

Nowadays, the camcorders are extremely modern and capable of transmitting the images live via satellite. In the image, the audio is also part of the process. Everything is quite "real" compared to what we had before (ie no image transmission). All in high definition, with thousands of different functions .Each unit also has its expertise. For any activity there is a different role in a film camera. On top of this, the quality of the material is such as to terms movies, recordings in television, novels and even live broadcasts.

8.Electric car battery

For over a century, Edison developed a nickel-iron rechargeable battery intended for use in cars. Surprisingly, this technology is still used by some people to store energy from solar panels and wind turbines. Now, Stanford engineers have improved it to carry a thousand times faster.Edison's original battery uses a cathode made of nickel and an iron anode, and is soaked in an alkaline solution. In Edison's time, the conductive elements contained some carbon to help them to work, but engineers from Stanford thought would be fun.

9.Phonograph

The phonograph is a device invented in 1877 by Thomas Edison for recording and playing sounds through a cilindro.Ele was the first device capable of recording and playing sounds. The invention of the phonograph by Edison was the culmination of a series of inventions first tried to accomplish the task of mechanically recording in any way sound vibrations. The great innovation of the phonograph lies in its ability to also play the sounds recorded, opening new possibilities of commercial use of sound.
