SOS Arana
SOS is a Morse code distress signal (), used internationally, originally established for maritime use. In formal notation SOS is written with an overscore line (), to indicate that the Morse code equivalents for the individual letters of "SOS" are transmitted as an unbroken sequence of three dots / three dashes / three dots, with no spaces between the letters. In International Morse Code three dots form the letter "S" and three dashes make the letter "O", so "S O S" became a common way to remember the order of the dots and dashes. IWB, VZE, 3B, and V7 form equivalent sequences, but traditionally SOS is the easiest to remember. SOS, when it was first agreed upon by the International Radio Telegraphic Convention in 1906, was merely a distinctive Morse code sequence and was initially not an abbreviation. Later a backronym was created for it in popular usage, and SOS became associated with mnemonic phrases such as "Save Our Souls" and "Save Our Ship". Moreover, due to its ...

Morse Code
Morse code is a telecommunications method which Character encoding, encodes Written language, text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy. International Morse code encodes the 26 ISO basic Latin alphabet, basic Latin letters to , one Diacritic, accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals (Prosigns for Morse code, prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration can vary for signal clarity and operator skill, but for any one message, once the rhythm is established, a beat (music), half-beat is the basic unit of time measurement in Morse code. The duration of a ''dah'' is three times the duration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sécurité
Sécurité (; French: ''sécurité'') (often repeated thrice, "Sécurité, sécurité, sécurité") is a procedure word used in the maritime radio service that warns the crew that the following message is important safety information. The most common use of this is by coast radio stations before the broadcast of navigational warnings and meteorological information. Navigational warnings are issued regularly and usually give information about people or vessels in distress and objects or events that can be an immediate danger to people at sea and how they are navigating. In the United States, MARAD (Marine Administration) sends out infrequent advisories about potential global political climate dangers. There are four types of navigational warnings, which are categorized by their location. These areas are NAVAREA IV, HYDROLANT, NAVAREA XII, and HYDROPAC. Meteorological information is information that is about the marine atmosphere. These meteorological advisories include the devel ...

French Language
French ( or ) is a Romance languages, Romance language of the Indo-European languages, Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Northern Old Gallo-Romance, a descendant of the Latin spoken in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien language, Francien) largely supplanted. It was also substratum (linguistics), influenced by native Celtic languages of Northern Roman Gaul and by the Germanic languages, Germanic Frankish language of the post-Roman Franks, Frankish invaders. As a result of French and Belgian colonialism from the 16th century onward, it was introduced to new territories in the Americas, Africa, and Asia, and numerous French-based creole languages, most notably Haitian Creole, were established. A French-speaking person or nation may be referred to as Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mayday
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications. It is used to signal a life-threatening emergency primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. Convention requires the word be repeated three times in a row during the initial emergency declaration ("Mayday mayday mayday"). History The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, officer-in-charge of radio at Croydon Airport, England. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency. Since much of the air traffic at the time was between Croydon and Le Bourget Airport in Paris, he proposed the term "mayday", the phonetic equivalent of the French (a short form of , "come ndhelp me") ...

United Wireless Telegraph Company
The United Wireless Telegraph Company was the largest radio communications firm in the United States, from its late-1906 formation until its bankruptcy and takeover by Guglielmo Marconi, Marconi interests in mid-1912. At the time of its demise, the company was operating around 70 land and 400 shipboard radiotelegraph installations — by far the most in the U.S. However, the firm's management had been substantially more interested in fraudulent stock promotion schemes than in ongoing operations or technical development. United Wireless' shutdown, following federal mail fraud prosecution, was hailed for eliminating one of the largest financial frauds of the period. However, its disappearance also left the U.S. radio industry largely under foreign influence, dominated by the British-controlled Marconi Wireless Telegraph Company of America (American Marconi). Formation United Wireless' establishment was announced with great fanfare in November 1906 by its founder and first preside ...
