Das Gerät ermöglicht die Erkennung von Metallobjekten und dient unter anderem zur Suche nach Untertagegruben. Es ist eine Art von Flugzeug, das einen oder mehrere Schwimmer hat, um auf Wasser schwimmen und sich bewegen zu können.
Alexander dachte, dass die Erfindung dieses Geräts für die Luftfahrt sehr wichtig sein würde und es war. Heutzutage werden Tragflügelboote hauptsächlich verwendet, um leichte Gegenstände zu Seen und anderen nahe gelegenen Gebieten zu transportieren.
Sie werden auch für Brandbekämpfungsmissionen eingesetzt und sind fast immer mehrdeutige Flugzeuge, dh sie arbeiten an Land und im Wasser.
In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time.
While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires.
By , Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.
On March 7, , Bell was granted his telephone patent. Watson, come here. I want you. In , the U. In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields.
Some of his other notable inventions were:. In , Bell was awarded the French Volta Prize, and with the money, he founded a facility devoted to scientific discovery, the Volta Laboratory in Washington, D.
Bell invented numerous techniques to help teach speech to the deaf and even worked with well-known author and activist Helen Keller.
He also helped launch Science magazine , and from to served as president of the National Geographic Society. In , Bell was given the controversial title of honorary president at the Second International Congress of Eugenics.
Later in his life, Bell focused on aviation and hydrofoil inventions. Some famous quotes attributed to Bell include:. Hier beschäftigte er sich ab auch mit akustischen Experimenten zur Aufzeichnung von Schallwellen.
Er versuchte sie sichtbar zu machen, um auch Gehörlosen eine optische Sprachkontrolle zu ermöglichen. Zwar scheiterten diese Versuche, doch hatte Bell damit die Voraussetzungen für die Konstruktion eines funktionierenden Telefons geschaffen.
Am Until the end of his life, Bell and his family would alternate between the two homes, but Beinn Bhreagh would, over the next 30 years, become more than a summer home as Bell became so absorbed in his experiments that his annual stays lengthened.
Both Mabel and Bell became immersed in the Baddeck community and were accepted by the villagers as "their own". Mabel and Bell mobilized the community to help victims in Halifax.
Although Alexander Graham Bell is most often associated with the invention of the telephone, his interests were extremely varied. These included 14 for the telephone and telegraph, four for the photophone , one for the phonograph , five for aerial vehicles, four for "hydroairplanes", and two for selenium cells.
Bell's inventions spanned a wide range of interests and included a metal jacket to assist in breathing, the audiometer to detect minor hearing problems, a device to locate icebergs, investigations on how to separate salt from seawater, and work on finding alternative fuels.
Bell worked extensively in medical research and invented techniques for teaching speech to the deaf. During his Volta Laboratory period, Bell and his associates considered impressing a magnetic field on a record as a means of reproducing sound.
Although the trio briefly experimented with the concept, they could not develop a workable prototype. They abandoned the idea, never realizing they had glimpsed a basic principle which would one day find its application in the tape recorder , the hard disc and floppy disc drive, and other magnetic media.
Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. He also anticipated modern concerns with fuel shortages and industrial pollution.
Methane gas, he reasoned, could be produced from the waste of farms and factories. At his Canadian estate in Nova Scotia, he experimented with composting toilets and devices to capture water from the atmosphere.
In a magazine interview published shortly before his death, he reflected on the possibility of using solar panels to heat houses.
Bell and his assistant Charles Sumner Tainter jointly invented a wireless telephone, named a photophone , which allowed for the transmission of both sounds and normal human conversations on a beam of light.
On June 21, , Bell's assistant transmitted a wireless voice telephone message a considerable distance, from the roof of the Franklin School in Washington, D.
Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone".
Bell is also credited with developing one of the early versions of a metal detector through the use of an induction balance, after the shooting of U.
President James A. Garfield in According to some accounts, the metal detector worked flawlessly in tests but did not find Guiteau 's bullet, partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static.
Bell's own detailed account, presented to the American Association for the Advancement of Science in , differs in several particulars from most of the many and varied versions now in circulation, by concluding that extraneous metal was not to blame for failure to locate the bullet.
Perplexed by the peculiar results he had obtained during an examination of Garfield, Bell "proceeded to the Executive Mansion the next morning It was then recollected that underneath the horse-hair mattress on which the President lay was another mattress composed of steel wires.
Upon obtaining a duplicate, the mattress was found to consist of a sort of net of woven steel wires, with large meshes. The extent of the [area that produced a response from the detector] having been so small, as compared with the area of the bed, it seemed reasonable to conclude that the steel mattress had produced no detrimental effect.
Meacham explained the basic principle of hydrofoils and hydroplanes. Bell considered the invention of the hydroplane as a very significant achievement.
Based on information gained from that article, he began to sketch concepts of what is now called a hydrofoil boat. Bell and assistant Frederick W.
Baldwin studied the work of the Italian inventor Enrico Forlanini and began testing models. This led him and Bell to the development of practical hydrofoil watercraft.
During his world tour of —11, Bell and Baldwin met with Forlanini in France. They had rides in the Forlanini hydrofoil boat over Lake Maggiore. Baldwin described it as being as smooth as flying.
On returning to Baddeck, a number of initial concepts were built as experimental models, including the Dhonnas Beag Scottish Gaelic for little devil , the first self-propelled Bell-Baldwin hydrofoil.
Pinaud's experience in boat-building enabled him to make useful design changes to the HD Bell's report to the U.
Navy permitted him to obtain two horsepower kilowatts engines in July On September 9, , the HD-4 set a world marine speed record of In , Bell had begun experiments to develop motor-powered heavier-than-air aircraft.
The AEA was first formed as Bell shared the vision to fly with his wife, who advised him to seek "young" help as Bell was at the age of In , Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in maroon silk.
Bell was a supporter of aerospace engineering research through the Aerial Experiment Association AEA , officially formed at Baddeck, Nova Scotia, in October at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate.
Curtiss , a motorcycle manufacturer at the time and who held the title "world's fastest man", having ridden his self-constructed motor bicycle around in the shortest time, and who was later awarded the Scientific American Trophy for the first official one-kilometre flight in the Western hemisphere , and who later became a world-renowned airplane manufacturer; Lieutenant Thomas Selfridge , an official observer from the U.
Federal government and one of the few people in the army who believed that aviation was the future; Frederick W. The AEA's work progressed to heavier-than-air machines, applying their knowledge of kites to gliders.
Moving to Hammondsport, the group then designed and built the Red Wing , framed in bamboo and covered in red silk and powered by a small air-cooled engine.
One of the AEA's inventions, a practical wingtip form of the aileron , was to become a standard component on all aircraft.
Bell allowed it to continue with experiments. Selfridge had also become the first person killed in a powered heavier-than-air flight in a crash of the Wright Flyer at Fort Myer , Virginia , on September 17, Their final aircraft design, the Silver Dart , embodied all of the advancements found in the earlier machines.
McCurdy from the frozen ice of Bras d'Or made the first aircraft flight in Canada. Bell was connected with the eugenics movement in the United States.
In his lecture Memoir upon the formation of a deaf variety of the human race presented to the National Academy of Sciences on November 13, the year of his election as a Member of the National Academy of Sciences , he noted that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that couples where both parties were deaf should not marry.
The committee unequivocally extended the principle to humans. Honors and tributes flowed to Bell in increasing numbers as his invention became ubiquitous and his personal fame grew.
Bell received numerous honorary degrees from colleges and universities to the point that the requests almost became burdensome. These included statuary monuments to both him and the new form of communication his telephone created, including the Bell Telephone Memorial erected in his honor in Alexander Graham Bell Gardens in Brantford , Ontario, in A number of historic sites and other marks commemorate Bell in North America and Europe, including the first telephone companies in the United States and Canada.
Among the major sites are:. These included the prestigious 'Volta Laboratory Association' , also known as the Volta Laboratory and as the 'Alexander Graham Bell Laboratory', and which eventually led to the Volta Bureau as a center for studies on deafness which is still in operation in Georgetown, Washington, D.
The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted.
In partnership with Gardiner Greene Hubbard , Bell helped establish the publication Science during the early s.
In , Bell was elected as the second president of the National Geographic Society , serving until , and was primarily responsible for the extensive use of illustrations, including photography, in the magazine.
He was one of the founders of the American Institute of Electrical Engineers in and served as its president from to The First Day of Issue ceremony was held on October 28 in Boston, Massachusetts, the city where Bell spent considerable time on research and working with the deaf.
The Bell stamp became very popular and sold out in little time. The stamp became, and remains to this day, the most valuable one of the series.
The illustrations on the reverse of the note include Bell's face in profile, his signature, and objects from Bell's life and career: users of the telephone over the ages; an audio wave signal ; a diagram of a telephone receiver; geometric shapes from engineering structures; representations of sign language and the phonetic alphabet; the geese which helped him to understand flight; and the sheep which he studied to understand genetics.
That first flight was made by an airplane designed under Dr. Bell's tutelage, named the Silver Dart. In , Bell was also named as one of the 10 greatest Scottish scientists in history after having been listed in the National Library of Scotland 's 'Scottish Science Hall of Fame'.
Alexander Graham Bell, who could not complete the university program of his youth, received at least a dozen honorary degrees from academic institutions, including eight honorary LL.
Bell died of complications arising from diabetes on August 2, , at his private estate in Cape Breton, Nova Scotia, at age Bell, saying: . My colleagues in the Government join with me in expressing to you our sense of the world's loss in the death of your distinguished husband.
It will ever be a source of pride to our country that the great invention, with which his name is immortally associated, is a part of its history.
On the behalf of the citizens of Canada, may I extend to you an expression of our combined gratitude and sympathy.
Bell's coffin was constructed of Beinn Bhreagh pine by his laboratory staff, lined with the same red silk fabric used in his tetrahedral kite experiments.
To help celebrate his life, his wife asked guests not to wear black the traditional funeral color while attending his service, during which soloist Jean MacDonald sang a verse of Robert Louis Stevenson 's "Requiem": .
Upon the conclusion of Bell's funeral, "every phone on the continent of North America was silenced in honor of the man who had given to mankind the means for direct communication at a distance".
Alexander Graham Bell was buried atop Beinn Bhreagh mountain, on his estate where he had resided increasingly for the last 35 years of his life, overlooking Bras d'Or Lake.
