Color Code
A color code is a system for displaying information by using different colors. The earliest examples of color codes in use are for long-distance communication by use of flags, as in semaphore communication. The United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety, with other colors having similar assignments of meaning. As chemistry and other technologies advanced, it became expedient to use coloration as a signal for telling apart things that would otherwise be confusingly similar, such as wiring in electrical and electronic devices, and pharmaceutical pills. The use of color codes has been extended to abstractions, such as the Homeland Security Advisory System color code in the United States. Similarly, hospital emergency codes often incorporate colors (such as the widely used "Code Blue" indicating a cardiac arrest), although they may also include numbers, and may not conform to a uniform standard.

Homeland Security Advisory System
In the United States, the Homeland Security Advisory System (HSAS) was a color-coded terrorism threat advisory scale created in March 2002 under the Bush Administration in response to the September 11 attacks. The different levels triggered specific actions by federal agencies and state and local governments, and they affected the level of security at some airports and other public facilities. It was often called the "terror alert level" by the U.S. media. The system was replaced on April 27, 2011, with a new system called the National Terrorism Advisory System. History The system was created by Homeland Security Presidential Directive 3 on March 11, 2002, in response to the September 11 attacks. It was meant to provide a "comprehensive and effective means to disseminate information regarding the risk of terrorist acts to federal, state, and local authorities and to the American people." It was unveiled March 12, 2002, by Tom Ridge, then the Assistant to the President for Home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 Pair Color Code Chart
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3 ...

Electronic Color Code
An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring. History Before industry standards were established, each manufacturer used their own unique system for color coding or marking their components. In the 1920s, the RMA resistor color code was developed by the Radio Manufacturers Association (RMA) as a fixed resistor coloring code marking. In 1930, the first radios with RMA color-coded resistors were built. Over many decades, as the organization name changed (RMA, RTMA, RETMA, EIA) so was the name of the code. Though known most recently as EIA color code, the four name variations are found in books, magazines, cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navigation Light
A navigation light, also known as a running or position light, is a source of illumination on a watercraft, aircraft or spacecraft, meant to give information on the craft's position, heading, or status. Some navigation lights are colour-coded red and green to aid traffic control by identifying the craft's orientation. Their placement is mandated by international conventions or civil authorities such as the International Maritime Organization (IMO). A common misconception is that marine or aircraft navigation lights indicate which of two approaching vessels has the "right of way" as in ground traffic; this is never true. However, the red and green colours are chosen to indicate which vessel has the duty to "give way" or "stand on" (obligation to hold course and speed). Consistent with the ground traffic convention, the rightmost of the two vehicles is usually given stand-on status and the leftmost must give way. Therefore a red light is used on the ( left (port)) side to indicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Characteristic Light
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, " ...

Role-playing Game
A role-playing game (sometimes spelled roleplaying game, RPG) is a game in which players assume the roles of player character, characters in a fictional Setting (narrative), setting. Players take responsibility for acting out these roles within a narrative, either through literal acting or through a process of structured decision-making regarding character development. Actions taken within many games succeed or fail according to a formal role-playing game system, system of rules and guidelines. There are several forms of role-playing games. The original form, sometimes called the tabletop role-playing game (TRPG), is conducted through discussion, whereas in live action role-playing game, live action role-playing (LARP), players physically perform their characters' actions.(Tychsen et al. 2006:255) "LARPs can be viewed as forming a distinct category of RPG because of two unique features: (a) The players physically embody their characters, and (b) the game takes place in a physica ...

League Of Legends
''League of Legends'' (''LoL''), commonly referred to as ''League'', is a 2009 multiplayer online battle arena video game developed and published by Riot Games. Inspired by ''Defense of the Ancients'', a Mod (video games), custom map for Warcraft III: Reign of Chaos, ''Warcraft III'', Riot's founders sought to develop a stand-alone game in the same genre. Since its release in October 2009, ''League'' has been free-to-play and is monetized through Freemium, purchasable character customization. The game is available for Microsoft Windows and macOS. In the game, two teams of five players battle in player-versus-player combat, each team occupying and defending their half of the map. Each of the ten players controls a character, known as a "champion", with unique abilities and differing styles of play. During a match, champions become more powerful by collecting experience points, earning gold, and purchasing Item (game terminology), items to defeat the opposing team. In ''League' ...

Magic (gaming)
Magic or mana is an attribute assigned to characters within a role-playing or video game that indicates their power to use special magical abilities or "spells". Magic is usually measured in magic points or mana points, shortened as MP. Different abilities will use up different amounts of MP."The History of Mana: How an Austronesian Concept Became a Video Game Mechanic" June 17, 2014, Alex Golub, Assistant Professor of Anthropology, University of Hawai‘i at Mānoa. When the MP of a character reaches zero, the character will not be able to use special abilities until some of their MP is recovered. Much like |
Health (gaming)
Health is an attribute in a video game or tabletop game that determines the maximum amount of damage or loss of stamina that a character or object can take before dying or losing consciousness. In role-playing games, this typically takes the form of hit points (HP), a numerical attribute representing the health of a character or object. The game character can be a player character, a boss, or a mob. Health can also be attributed to destructible elements of the game environment or inanimate objects such as vehicles and their individual parts. In video games, health is often represented by visual elements such as a numerical fraction, a health bar or a series of small icons, though it may also be represented acoustically, such as through a character's heartbeat. Mechanics In video games, as in tabletop role-playing games, an object usually loses health as a result of being attacked. Protection points or armor help them to reduce the damage taken. Characters acting as tanks usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-phase Electric Power
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
