When did they invent baby incubator?
FARNSWORTH, PHILO T. Philo Taylor Farnsworth (1906-1971) was an American inventor. Farnsworth invented many important components of the television, including power, focusing systems, synchronizing the signal, contrast, controls, and scanning. He also invented a radar system, a cold cathode ray tube, a new type of baby incubator, and the first electronic microscope. Farnsworth held over 300 patents. They were first developed in the 1950's-1960's. However at Southmead Hospital, Bristol, UK, they used a model in 1948. Some baby incubators, similar to those used for hatching chicks, were devised in the late nineteenth century. In the United States these were shown at commercial exhibitions, complete with babies inside, until 1943.
What materials did Philo Farnsworth use to create the first tv?
Philo Farnsworth didn't use any materials to create the first television because John Logie Baird built and demonstrated the world's first television in 1925, three years before Farnsworth had his own version running in 1928. Farnsworth however did produce the first television that had no moving parts. He achieved this in 1929.
The history of the TV?
In 1921 the 14-year-old Mormon had an idea while working on his father's Idaho farm. Mowing hay in rows, Philo realized an electron beam could scan a picture in horizontal lines, reproducing the image almost instantaneously. This would prove to be a critical breakthrough in Philo Farnsworth's invention of the television in 1927. Earlier TV devices had been based on an 1884 invention called the scanning disk, patented by Paul Nipkow. Riddled with holes, the large disk spun in front of an object while a photoelectric cell recorded changes in light. Depending on the electricity transmitted by the photoelectric cell, an array of light bulbs would glow or remain dark. Though Nipkow's mechanical system could not scan and deliver a clear, live-action image, most would-be TV inventors still hoped to perfect it. Not Philo Farnsworth. In 1921 the 14-year-old Mormon had an idea while working on his father's Idaho farm. Mowing hay in rows, Philo realized an electron beam could scan a picture in horizontal lines, reproducing the image almost instantaneously. It would prove to be a critical breakthrough. But young Philo was not alone. At the same time, Russian immigrant Vladimir Zworykin had also designed a camera that focused an image through a lens onto an array of photoelectric cells coating the end of a tube. The electrical image formed by the cells would be scanned line-by-line by an electron beam and transmitted to a cathode-ray tube. Rather than an electron beam, Farnsworth's image dissector device used an "anode finger" -- a pencil-sized tube with a small aperture at the top -- to scan the picture. Magnetic coils sprayed the electrons emitted from the electrical image left to right and line by line onto the aperture, where they became electric current. Both Zworykin's and Philo's devices then transmitted the current to a cathode-ray tube, which recreated the image by scanning it onto a fluorescent surface. Farnsworth applied for a patent for his image dissector in 1927. The development of the television system was plagued by lack of money and by challenges to Farnsworth's patent from the giant Radio Corporation of America (RCA). In 1934, the British communications company British Gaumont bought a license from Farnsworth to make systems based on his designs. In 1939, the American company RCA did the same. Both companies had been developing television systems of their own and recognized Farnsworth as a competitor. World War II interrupted the development of television. When television broadcasts became a regular occurrence after the war, Farnsworth was not involved. Instead, he devoted his time to trying to perfect the devices he had designed. David Sarnoff, vice president of the powerful Radio Corporation of America, later hired Zworykin to ensure that RCA would control television technology. Zworykin and Sarnoff visited Farnsworth's cluttered laboratory, but the Mormon inventor's business manager scoffed at selling the company -- and Farnsworth's services -- to RCA for a piddling $100,000. So Sarnoff haughtily downplayed the importance of Philo's innovations, saying, "There's nothing here we'll need." In 1934 RCA demonstrated its "iconoscope," a camera tube very similar to Farnsworth's image dissector. RCA claimed it was based on a device Zworykin tried to patent in 1923 -- even though the Russian had used Nipkow's old spinning disk design up until the time he visited Philo's lab. The patent wars had truly begun -- and Phil, as the grown-up Farnsworth preferred to be called, was in a bind. He could not license his inventions while the matter was in court, and he wrestled with his backers over control and direction of his own company. The men in Farnsworth's loyal "lab gang" were fired and rehired several times during his financial ups and downs, but retained confidence in Phil. When Farnsworth's financiers refused his request for a broadcasting studio, the inventor and a partner built a studio on their own. Meanwhile back at RCA, Sarnoff had spent more than $10 million on a major TV R & D effort. At the 1939 New York World's Fair, Sarnoff announced the launch of commercial television -- though RCA's camera was inadequate, and the corporation didn't own a single TV patent. Later that same year, the company was compelled to pay patent royalties to Farnsworth Radio and Television. By the time World War II began, Farnsworth realized that commercial television's future was in the hands of businessmen -- not a lone inventor toiling in his lab. With his patents about to expire, Phil grew depressed, drunk and addicted to painkillers. In 1949 he reluctantly agreed to sell off Farnsworth Radio and Television. Philo T. Farnsworth was always an outsider, a bright star blazing in the dawn of a new electronic age. His romance with the electron was a private affair, a celebration of the spirit of the lone inventor.
Four outstanding events Philo farnsworth had done?

When was TV was invented and why it was it invented?
John Logie Baird transmitted the first pictures over radio waves and proved it could be done. he demonstarted it on Jan 27th 1926 and broadcast for the BBC on Sept 30th 1929, the first public broadcast of television. TV was invented to bring moving pictures into the home, instead of having to go out to the cinema. Many people said it would never catch on. Philo Taylor Farnsworth invented the first fully modern electronic television system. He was the first inventor to transmit a television image of a dollar sign (comprised of 60 horizontal lines.) Farnsworth developed the dissector tube, the basis of all current electronic televisions. This was an improvement on mechanical televisions.
Who thought of the idea to make the television?
Philo T. Farnsworth, invented it in 1921 while plowing a field at age 14 and disclosed his ideas to his high school chemistry teacher in 1922. He first demonstrated a working version of his electronic television in 1927.
Who invented radios and TVs?
Philo Farnsworth (1906-1971), American inventor and pioneer in television technology. Farnsworth developed a television system complete with receiver and camera, but he failed to produce his system commercially.Philo Taylor Farnsworth was born in Beaver, Utah. His family moved to Rigby, Idaho, when he was 11 years old, where Farnsworth began experimenting with electricity. In 1920, when Farnsworth was 14, he showed his high school chemistry teacher a design he had made for an electronic television. The next year Farnsworth entered Brigham Young University as a special freshman. Farnsworth soon left school and worked at odd jobs until he met a willing investor who lent him money to start building his television.The television systems being experimented with at that time consisted of a system of spinning disks with holes punched in them and mirrors designed to convert light to electricity. These disks and mirrors could give only poor resolution. Farnsworth called his device an image dissector because it converted individual elements of the image into electricity one at a time. He replaced the spinning disks with cesium, an element that emits electrons when exposed to light. Farnsworth applied for a patent for his image dissector in 1927. The development of the television system was plagued by lack of money and by challenges to Farnsworth's patent from the giant Radio Corporation of America (RCA). He spent his career as head of the Farnsworth Television and Radio Corporation, which he founded in 1929.In 1934, the British communications company British Gaumont bought a license from Farnsworth to make systems based on his designs. In 1939, the American company RCA did the same. Both companies had been developing television systems of their own and recognized Farnsworth as a competitor. World War II (1939-1945) interrupted the development of television. When television broadcasts became a regular occurrence after the war, Farnsworth was not involved. Instead, he devoted his time to trying to perfect the devices he had designed.In addition to his television system, Farnsworth invented the first simple electronic microscope and the cold cathode-ray tube, which was used in some early televisions. A cathode-ray tube (CRT) is an electron tube that converts electrical signals into a pattern on a screen and forms the basis of the television receiver. Unlike most cathode-ray tubes, cold cathode-ray tubes produce electrons without being heated.Farnsworth also worked as a consultant in electronics and later as a researcher in atomic energy. He conducted research on radar and on nuclear energy. Farnsworth held 165 patents, mostly in radio and television..
