000 lights. According to Edison, Hammer was "the pioneer of incandescent lighting equipment". Most of Edison's patents are public patents. During Edison's lifetime, inventions protected by patents 17 years included electronic, mechanical or chemical products. About 12 items are design patents, and one decoration design has been protected by 14 years. Most of his inventions are not completely original, but improvements on products that have been invented but are not perfect. The first few were phonographs, and the phonograph patent was the first device to record and reproduce sound. Edison didn't invent the first electric light bulb, but he invented the first incandescent lamp that could be actually used in business. Some early inventors have developed some designs, including the patents he bought from Henry Woodward, Matthew Evans, Moses G Fama, Yue Se Swan, James Bowen Lentesy, William Sawyer, humphry davy and Henry Goldberg. The products of these inventors have shortcomings such as short life, high production cost and large channel current, and are only suitable for satisfying the curiosity of laboratories. In 1878, Edison used thin wires to transmit luminous wire elements (used by British inventor Yue Se Swan before). Edison adopted the characteristics of these old designs and arranged for his workers to create durable light bulbs. Before 1879, he had a new concept: a high-resistance lamp would burn for hundreds of hours in high vacuum. When Alexandra Volta, an earlier inventor, produced electric lighting equipment in 1800, Edison focused on commercial applications, and extended this concept to families and enterprises through mass production of relatively durable light bulbs, and created a complete system of electric power production and distribution. Menlo Park Research Laboratory may be able to cope with the sales of the "Quadruple Communicator" invented by Edison in 1874 (four signal communicators can be sent at the same time on the same wire). When Edison made an offer to Western Union, he was shocked by the unexpected huge sum offered by Western Union-the patent right was sold at the price of 10.

[Source Request] 1883,/kloc-0 10 On October 8th, the US Patent Office ruled that Edison's patent was based on the work of William Sawyer, so it was invalid. The lawsuit lasted for almost six years, until June 6, 1889+ 10, when the judge ruled that Edison's request for electric light improvement was legal. In order to avoid a possible lawsuit with Yue Se Swan, he and Swan set up a joint venture company named "Eddis Swan" in Britain to sell inventions. Other inventors who designed electric lamps included Serbian inventor nikola tesla, who wanted to ignite radio bulbs from side electrodes by radio frequency electroplating under the Tesla effect. He also plans to develop a wire to refocus energy from the glass shell back to the center of the light bulb, and then use the center "button" to emit incandescent light to ignite the light bulb. Although Tesla invented fluorescent lighting, Edison's design won at this time. Edison obtained the patent of power distribution system in 1880, which was very important for the invention of electric light. My first investment in all electrical industries was 1882 new york Pearl Street Station. 1On September 4th, 882, Edison opened the world's first power distribution system at Pearl Street Power Station, providing 1 10 volt direct current (DC) to 59 customers in lower Manhattan. On June 9, 2009, the first standardized incandescent lamp system using overhead wires was put into use in Roselle, New Jersey.

In the 1920s, carbon electrode microphones were also used for radio broadcasting and broadcasting. [Editor] Picture of this debate: PyramidParthen on's luxurious display of electric lights quickly became a public feature. This picture was shown at 1897 Tennessee Centennial Expo. Because Edison advocated direct current (DC) to transmit electricity more easily, and George Westinghouse sold the alternating current (AC) system developed by Tesla, Westinghouse and Edison became enemies. Unlike DC, alternating current can reach a very high voltage through a transformer, send it to a young conductor, and then reduce the voltage at the destination to supply power to users. Although Edison thought contempt was the main blow, the war with AC led Edison to gradually intervene in the development and promotion of electric chairs to show the greater fatal potential of AC for "safer" DC. Edison launched a short but powerful campaign to ban the use of alternating current, or to limit the allowable voltage for safety purposes. As part of this campaign, Edison showed dogs, cats and an elephant that were electrocuted to show the danger of alternating current. Tesla's AC has replaced DC's power generation and energy distribution in many cases, which has great extensibility and improves the safety and efficiency of energy distribution. Although DC finally lost its power distribution advantage, it is still mainly used in long-distance HVDC transmission systems. [Editor] Frank J. Sperberg, a capable mathematician and former naval officer, was recruited by Edward H. Johnson and joined Edison's organization on 1883. Spielberg's great contribution to Edison's laboratory in Menlo Park was to expand Edison's mathematical methods. Although it is believed that Edison didn't use mathematics, the notebook he analyzed revealed that he was a shrewd man in mathematical analysis. For example, the important parameters of his electric lamp system, including the resistance of the electric lamp, are skillfully analyzed by ohm's law, Joule's law and economics. The key to Edison's success is holism, not reductionism. In the absence of a suitable theory, he explored inventions and made extensive use attempts. Starting with the patent added by Spenger in 1883, it may be interpreted as a change to the reductionist analysis method, which is not necessarily Edison's positive movement. Sperberg's important analytical contributions, including correcting Edison's main and central distribution and supply systems, formed a rebuttal to this. 1884, the development of electricity placed elsewhere aroused the interest of Berger. He left Edison and founded the Spielberg Circuit and Motor Company. However, Spager, who later developed many electronic inventions, always trusted Edison who worked together. Another assistant of Edison claimed that Edison promised to give him $50 if he succeeded in improving his DC.
000 nikola tesla. A few months later, when he finished his work and asked for payment, Tesla claimed that Edison said, "When you become a complete American, you will appreciate American jokes. [5] Tesla resigned immediately. This anecdote is a bit dubious, because the salary in Tesla is $65,438 +08, and a weekly bonus will be paid in 53 years, which is equal to the initial capital of the company. After being rejected, Tesla was trained to $25 and resigned every week (Jonnes, p 1 10). Although Tesla later accepted the Edison Award and publicly declared that Edison was an inventor and engineer with high views, he persisted. One day after Edison's death, the new york Times widely reported Edison's life. When the only negative comment came from Tesla, he was quoted as saying: "He has no hobbies, doesn't care about any kind of entertainment, and completely ignores the most basic hygiene rules. "His efficiency is very low, so there must be a huge excuse to cover up everything, unless he is blindly and accidentally mediated. At first, I may be one of his regretful witnesses, knowing that some theories and calculations saved him 90% of the labor force. But he does despise the knowledge and mathematics in the book, and he completely trusts the genius of invention and the pragmatic American style. When Edison was very old and dying, he said that the biggest mistake he made was not respecting Tesla and his work. [6] Mainly invented the phonograph, movable film projector, dictation phonograph, radio incandescent lamp, signature printer and tattoo gun.
American inventor and businessman Thomas Alva Edison invented many important devices. Awarded the title of "Menlo Park's Wizards" by newspaper reporters, he is the first inventor in the world to use the principle of mass production and his industrial research laboratory to produce inventions. Edison is considered to be the greatest inventor in the contemporary era. He registered 1093 patents under his name. Most of the inventions are not original, but some other patents are improved, but in fact many of them were invented by many of his employees. Therefore, Edison is often criticized for not sharing these advantages. However, Edison obtained patents from many countries, including the United States, Britain, France and Germany. General Electric Company was founded in 1892, and later became the largest company in the United States: General Electric Company. * * owns 244 14 patents, including Edison's 1093 patents. 1908, Edison founded the film patent company, an enterprise group composed of nine film studios. In the early 1960s, Edison bought a villa in Formel, Florida as a shelter from the cold. Henry Ford, the car king, lives opposite this villa. He is also a good friend of Edison. "Edison and Ford Winter Manor" is currently open to the public. Monroe Park Edison's Monroe Park Lab moved to Greenfield Village in dearborn, Michigan. (Pay attention to the equipment in the back wall) Edison's main invention was built in Menlo Park, New Jersey. It is the first institution to set specific goals, aiming at guiding continuous technological innovation and improvement. Although many employees do research and development in his direction, most of the inventions there are legally attributed to Edison. William Yue Se Hammer, a consulting electrical engineer, began to work as an experimenter under Edison in February 1879. He assisted in the experiment of telephone, phonograph, circuit, iron ore separator and electric lighting equipment, and developed other inventions. However, the hammer is mainly responsible for testing and recording incandescent lamp equipment. 1880 was appointed as the chief engineer of Edison lamp. In his first year in office, under the leadership of general manager Francis Robbins Upton, the factory built 50 cars.

Thomas Alva Edison 1847 was born in Ohio, USA. He invented more than 2000 kinds in his life. He not only became an outstanding scientist in the history of modern physics, but also was regarded as the greatest inventor in the world. Edison's outstanding achievements in his life are not a fluke, but the result of his perseverance, courage to try and innovate. Because of his poor family, Edison received only three months of primary education and began to work on the train at the age of twelve. Even so, he studied hard and taught himself hard. When he was a teenager, he became interested in natural science. He not only mastered a wealth of knowledge of electricity and chemistry, but also liked to carry out some "small experiments" in the car and at home. 1863 worked as a waiter in a railway company, and his invention career began. With the birth of his inventions one after another, his name became familiar and his life gradually enriched. 1873, Edison made a duplex transmitter, and the following year he made a four-beam transmitter. 1876, he established the first American industrial research laboratory in Menlo Park, that is, the Edison Invention Factory. In the next two years, he invented the phonograph, which caused a sensation all over the world and won him the title of French jazz. Edison's greatest contribution in his life was the invention of the electric light. He did 1600 experiments on heat-resistant materials and more than 600 kinds of plant fibers before making the first light bulb. Later, he constantly improved the manufacturing method on this basis. In order to promote the use of electric lights, he developed various additional equipment for electrical systems, such as parallel circuits, fuses, insulation materials, copper wire networks and so on. It also made a generator with stable voltage and a three-wire switch to realize economic distribution. 1882, he set up a power grid in new york. Although he limited the transmission distance by means of direct current transmission, this great contribution greatly improved human life. Thermoionic emission was discovered by Edison in 1883, which laid the foundation for the appearance of electron tubes. 1887, he set up a bigger laboratory in West Orange. His inventions are numerous, the most important of which is the movie camcorder of 1888; 1896 movie projector and ferronickel? Batteries. His invention after invention earned him the special gold medal of Congress in 1928. 193 1 year, Edison died in west orange at the age of 84.

Edison was born in the United States on 1847. Edison read a lot of books when he was a child, and he often learned about new things around him. Edison worked hard. Failing, he will try again after thinking clearly. Edison invented more than 2000 kinds, including phonograph, video camera and electric light. 193 1 year, Edison died at the age of 84.
The King of Invention-Edison Name: Thomas Alva. Edison, Thomas Born: 1847, the golden sentence "Genius is one point of talent, plus ninety-nine points of effort" in Ohio, USA. Statistics show that he made a new invention every 15 days in his life! Edison is a great inventor in the world. He invented nearly 1 100 kinds of inventions. He was born in a poor peasant family in the United States on 1847. When Edison was seven years old, he was kicked out of school by the headmaster and the teacher because the school teacher thought he was mentally retarded. Later it was taught by Edison's mother. When Edison was ten years old, he set up a laboratory at home to carry out various types of chemical experiments. When Edison was twelve years old, he had to sell newspapers on the train to make a living because of his poor family life. He also carried out various chemical experiments in the luggage compartment of the train. 1880 Edison set up a chemical research institute shortly after using the invented movie camera. Some great inventions, such as electric light, telephone and phonograph, were invented in this research institute. Edison invented nearly 1000 inventions in his life. These inventions were successfully created by Edison through continuous efforts, failures and attempts. Therefore, we should learn from Edison's spirit of never failing and constantly trying.
