Telefax
Fax (short for facsimile), sometimes called telecopying or telefax (the latter short for telefacsimile), is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black. Fax machines were ubiquitous in office environments in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Bain (inventor)
Alexander Bain (12 October 1810 – 2 January 1877) was a Scottish inventor and engineer who was first to invent and patent the electric clock. He invented the Telegraph Clock, which was a technology of synchronizing many electric clocks placed anywhere in the world; they would all have the exact same time. He also invented and patented the technology of the facsimile machine for scanning images and transmitting them across telegraph lines hundreds of miles away. He installed the railway telegraph lines between Edinburgh and Glasgow, Scotland, for recording messages, to regulate the safe movement of trains, marking time, giving signals, and printing information at different locations. He invented a chemical telegraph technology of being able to transmit across a telegraph line messages at up to 1000 words per minute, while at the time Morse's telegraph could only produce 40 words a minute. Early life Bain was born in Houstry, near Watten, Caithness, Scotland. He was born o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telegram
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling. ...

Frederick Bakewell
Frederick Collier Bakewell (29 September 1800 – 26 September 1869) was an English physicist who improved on the concept of the facsimile machine introduced by Alexander Bain in 1842 and demonstrated a working laboratory version at the 1851 World's Fair in London. Biography Born in Wakefield, West Yorkshire, he eventually moved to Hampstead, Middlesex where he lived until his death. He is buried in a family grave in Kensal Green Cemetery. Bakewell was married to Henrietta Darbyshire with whom he had two sons, Robert and Armitage. Image telegraph Bakewell's "image telegraph" had many of the features of modern facsimile machines, and replaced the pendulums of Bain's system with synchronized rotating cylinders. The system involved writing or drawing on a piece of metal foil with a special insulating ink; the foil was then wrapped around a cylinder which slowly rotated, driven by a clock mechanism. A metal stylus driven by a screw thread traveled across the surface of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telautograph
The telautograph is an analog precursor to the modern fax machine. It transmits electrical impulses recorded by potentiometers at the sending station to servomechanisms attached to a pen at the receiving station, thus reproducing at the receiving station a drawing or signature made by the sender. It was the first such device to transmit drawings to a stationary sheet of paper; previous inventions in Europe had used rotating drums to make such transmissions. Invention The telautograph's invention is attributed to Elisha Gray, who patented it on July 31, 1888. Gray's patent stated that the telautograph would allow "one to transmit his own handwriting to a distant point over a two-wire circuit." It was the first facsimile machine in which the stylus was controlled by horizontal and vertical bars. The telautograph was first publicly exhibited at the 1893 World's Columbian Exposition held in Chicago. While the patent schema's geometry implies vertical and horizontal coordinat ...

Western Union
The Western Union Company is an American multinational financial services company, headquartered in Denver, Colorado. Founded in 1851 as the New York and Mississippi Valley Printing Telegraph Company in Rochester, New York, the company changed its name to the Western Union Telegraph Company in 1856 after merging with several other telegraph companies. The company dominated the American telegraphy industry from the 1860s to the 1980s, pioneering technology such as telex and developing a range of telegraph-related services (including wire money transfer) in addition to its core business of transmitting and delivering telegram messages. After experiencing financial difficulties, Western Union began to move its business away from communications in the 1980s and increasingly focused on its money transfer services. The company ceased its communications operations completely in 2006, at which time The New York Times described it as "the world's largest money-transfer business" ...

Calvin Coolidge
Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872January 5, 1933) was the 30th president of the United States from 1923 to 1929. Born in Vermont, Coolidge was a Republican lawyer from New England who climbed up the ladder of Massachusetts state politics, becoming the state's 48th governor. His response to the Boston Police Strike of 1919 thrust him into the national spotlight as a man of decisive action. Coolidge was elected the country's 29th vice president the next year, succeeding the presidency upon the sudden death of President Warren G. Harding in 1923. Elected in his own right in 1924, Coolidge gained a reputation as a small-government conservative distinguished by a taciturn personality and dry sense of humor, receiving the nickname "Silent Cal". Though his widespread popularity enabled him to run for a third term, he chose not to run again in 1928, remarking that ten years as president was (at the time) "longer than any other man has had ittoo long! ...

Radiofax
Radiofacsimile, radiofax or HF fax is an analogue mode for transmitting monochrome images via high frequency (HF) radio waves. It was the predecessor to slow-scan television (SSTV). It was the primary method of sending photographs from remote sites (especially islands) from the 1930s to the early 1970s. It is still in limited use for transmitting weather charts and information to ships at sea. History Richard H. Ranger, an electrical engineer working at Radio Corporation of America (RCA), invented a method for sending photographs through radio transmissions. He called his system the wireless photoradiogram, in contrast to the fifty-year-old telefacsimile devices which used first telegraphic wires, and then later was adapted to use the newer telephone wires. On 29 November 1924, Ranger's system was used to send a photograph from New York City to London. It was an image of President Calvin Coolidge and was the first transoceanic radio transmission of a photograph. Also that y ...

Richard H
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", " Rich", "Rick", " Rico", " Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish.
