Reginald Fessenden
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-American electrical engineer and inventor who received hundreds of List of Reginald Fessenden patents, patents in fields related to radio and sonar between 1891 and 1936 (seven of them after his death). Fessenden pioneered developments in radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906). In 1932 he reported that, in late 1906, he also made the first radio broadcast of entertainment and music, although that claim has not been well documented. He did a majority of his work in the United States and, in addition to his Canadian citizenship, claimed U.S. citizenship through his American-born father. Early years Reginald Fessenden was born October 6, 1866, in East Bolton, Quebec, East Bolton, Canada East, the eldest of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Townships
The Eastern Townships (, ) is a historical administrative region in southeastern Quebec, Canada. It lies between the Great Lakes–St. Lawrence Lowlands, St. Lawrence Lowlands and the American border, and extends from Granby, Quebec, Granby in the southwest to Drummondville in the northeast. Since 1987, most of the area is within the administrative region Estrie, and the term Eastern Townships is now used in tourist literature. The name derives from there also being western townships in Ontario. History Before European colonization of the Americas, European colonization the area was inhabited by the Abenaki, as attested by many toponyms such as Lake Memphremagog and Massawippi River. Until 1791 the region was organized under the seigneurial system of New France. In 1791 the region was resurveyed under English law. It was divided into List of former counties of Quebec, counties, which were in turn subdivided into township (Canada), townships. Settlement by Europeans happened ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Radio
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edison Machine Works
The Edison Machine Works was a manufacturing company set up to produce dynamos, large electric motors, and other components of the electrical illumination system being built in the 1880s by Thomas A. Edison in New York City. In 1892, its Schenectady, New York plant would become General Electric. History The need for equipment in the development of a large-scale electric illumination "utility" in New York City, starting around 1880, soon outstripped the capacity of Thomas Edison's machine shop at Menlo Park. To alleviate the problem in 1881 Edison leased the old Etna Iron Works at 104 Goerck Street, Lower Manhattan and set up the ''Edison Machine Works'' with Edison providing 90% of the capital and investor partner Charles Batchelor providing 10%. The workforce built up to some 800 men supervised by Edison machinist Charles Dean. This shop supplied jumbo dynamos for the original Pearl Street Station as well as dynamos of various sizes for the different types of electric light ...
