Signalman (rank)
Signalman was a U.S. Navy rating for sailors that specialized in visual communication. See Signaller for more about the roles of Signalmen. United States usage U.S. Navy A signal lamp (also called an Signal Searchlight) is a visual signaling device for optical communication In the U.S. Navy, "signalman" (nicknamed "Sigs", "Flags", or "Skivvy Waver") was a job field combining both visual communications, and advanced lookout skills. While there was certainly a Signalman rating before World War II (the Signalman rating is one of the oldest in the Navy), a specialized Signalman rating was established shortly after the war. Then, Signalmen were identified by the symbol of two crossed semaphore flags on the left sleeve of the uniform, integrated with their rank insignia. Signalmen were responsible for transmitting, receiving, encoding, decoding, and distributing messages obtained via the visual transmission systems of flag semaphore, visual Morse code, and flaghoist signalling.

Master-at-arms (United States Navy)
The Master-at-Arms (MA) rating is responsible for law enforcement and force protection in the United States Navy—equivalent to the United States Army Military Police, the United States Marine Corps Military Police, the United States Air Force Security Forces, and the United States Coast Guard's Maritime Law Enforcement Specialist. It is one of the oldest ratings in the United States Navy, having been recognized since the inception of the U.S. Navy. It has had two rating badges during its history. Its original MA rating mark was an upright star (two points down) until the rating’s disestablishment in 1921. On 20 May 1958 the upright star reemerged as a nod to the Historical MA Rating whose duty was to provide good order and discipline aboard ships over the enlisted crews. When two senior pay grades were established in 1958, a single (E-8) or double (E-9) upright star (two points down) was placed above the anchor for all collar devices and rating badges. The MCPON Rating (1971) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Communication
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a Universality (philosophy), universal phenomenon and a Communication studies, specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing Semantics, meaning among Subject (philosophy), entities or Organization, groups through the use of sufficiently mutually understood signs, symbols, and Semiosis, semiotic conventions.

Signalling Light
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' includes audio, video, speech, image, sonar, and radar as examples of signal. A signal may also be defined as observable change in a quantity over space or time (a time series), even if it does not carry information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signaling occurs in all organisms even at cellular levels, with cell signaling. Signaling theory, in evolutionary biology, proposes that a substantial driver for evolution is the ability of animals to communicate with each other by developing ways of signaling. In human engineering, signals are typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
War On Terror

Quartermaster
Quartermaster is a military term, the meaning of which depends on the country and service. In land armies, a quartermaster is generally a relatively senior soldier who supervises stores or barracks and distributes supplies and provisions. In many navies, a quartermaster is an officer with particular responsibility for steering and signals. The seaman is a non-commissioned officer (petty officer) rank; in some others, it is not a rank but a role related to navigation. The term appears to derive from the title of a German royal official, the . This term meant "master of quarters" (where "quarters" refers to lodging or accommodation). Alternatively, it could have been derived from "master of the quarterdeck" where the helmsman and captain controlled the ship. The term's first use in English was as a naval term, which entered English in the 15th century via the equivalent French and Dutch naval titles and , respectively.

Flaghoist Signalling
Flag signals can mean any of various methods of using flags or pennants to send signals. Flags may have individual significance as signals, or two or more flags may be manipulated so that their relative positions convey symbols. Flag signals allowed communication at a distance before the invention of radio and are still used especially in connection with ships. Flaghoist signalling Flaghoist signalling is one or more flags (or pennants) simultaneously flying from a fixed halyard, and generally any method of signaling by such means. Each of the flags has a distinct shape and color combination. Each flag or combination of flags has a preassigned meaning or "code". The International Code of Signals defines a standard set of flags and associated alphabet suitable for international use, as well as a set of standard codes. Flaghoist is also used in boat racing, to warn of impending severe weather, and other specialized applications. Maritime flag signalling has a long history, espe ...
