Programmable Machine
A program is a set of instructions used to control the behavior of a machine. Examples of such programs include: *The sequence of cards used by a Jacquard loom to produce a given pattern within weaved cloth. Invented in 1801, it used holes in punched cards to represent sewing loom arm movements in order to generate decorative patterns automatically. *A computer program (software) is a list of instructions to be executed by a computer. *Barrels, punched cards and music rolls encoding music to be played by player pianos, fairground organs, barrel organs and music boxes. *A music sequencer is a programmable musical instrument. It was the earliest type of programmable machine. The first music sequencer was an automated flute player invented by the Persian Banu Musa brothers, described in their ''Book of Ingenious Devices'', in the 9th century. In 1206, the Muslim inventor Al-Jazari (in the Artuqid Sultnate) invented programmable automata, which incorporated the first programmable dru ...

Machine
A machine is a physical system using Power (physics), power to apply Force, forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input fo ...

Book Of Ingenious Devices
The ''Book of Ingenious Devices'' (Arabic: كتاب الحيل ''Kitab al-Hiyal'', Persian: كتاب ترفندها ''Ketab tarfandha'', literally: "The Book of Tricks") is a large illustrated work on mechanical devices, including automata, published in 850 by the three brothers of Persian descent, known as the Banu Musa (Ahmad, Muhammad and Hasan bin Musa ibn Shakir) working at the House of Wisdom (''Bayt al-Hikma'') in Baghdad, Iraq, under the Abbasid Caliphate. The book described about one hundred devices and how to use them. Overview The book was commissioned by the Abbasid Caliph of Baghdad, also made by Al-Jazari, Abu Jafar al-Ma'mun ibn Harun (786–833), who instructed the Banu Musa to acquire all of the Hellenistic texts that had been preserved by monasteries and by scholars during the decline and fall of Roman civilization. The Banū Mūsā brothers invented a number of automata (automatic machines) and mechanical devices, and they described a hundred such devices in ...

Arab Inventions
The Arabs (singular: Arab; singular ar, عَرَبِيٌّ, DIN 31635: , , plural ar, عَرَب, DIN 31635: , Arabic pronunciation: ), also known as the Arab people, are an ethnic group mainly inhabiting the Arab world in Western Asia, North Africa, the Horn of Africa, and the western Indian Ocean islands (including the Comoros). An Arab diaspora is also present around the world in significant numbers, most notably in the Americas, Western Europe, Turkey, Indonesia, and Iran. In modern usage, the term "Arab" tends to refer to those who both carry that ethnic identity and speak Arabic as their native language. This contrasts with the narrower traditional definition, which refers to the descendants of the tribes of Arabia. The religion of Islam was developed in Arabia, and Classical Arabic serves as the language of Islamic literature. 93 percent of Arabs are Muslims (the remainder consisted mostly of Arab Christians), while Arab Muslims are only 20 percent of the global Mus ...

Computing Terminology
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical concep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthesizer
A synthesizer (also spelled synthesiser) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II Sound Synthesizer, RCA Mark II, which was controlled with Punched card, punch cards and used hundreds of vacuum tubes. The Moog synthesizer, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programmable Thermostat
A programmable thermostat is a thermostat which is designed to adjust the temperature according to a series of programmed settings that take effect at different times of the day. Programmable thermostats are also known as setback thermostats or clock thermostats. Benefits Heating and cooling losses from a building (or any other container) become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable. For example, during cooling season, a programmable thermostat used in a home may be set to allow the temperature in the house to rise during the workday when no one will be at home. It may then be set to turn on the air conditioning before the arrival of occupants, allowing the house to be cool upon the arrival of the occupants while still having saved air conditioning energy during the peak ...

Automata
An automaton (; plural: automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions.Automaton – Definition and More from the Free Merriam-Webster Dictionary http://www.merriam-webster.com/dictionary/automaton Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power. Since long ago, the term is commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. Etymology The word "automaton" is the latinization of the Ancient Greek , , (neuter) "acting of one's own will". This word was first used by Homer to describe an automatic door opening, or au ...

Artuqids
The Artuqid dynasty (alternatively Artukid, Ortoqid, or Ortokid; , pl. ; ; ) was a Turkoman dynasty originated from tribe that ruled in eastern Anatolia, Northern Syria and Northern Iraq in the eleventh through thirteenth centuries. The Artuqid dynasty took its name from its founder, Artuk Bey, who was of the Döger branch of the Oghuz Turks and ruled one of the Turkmen beyliks of the Seljuk Empire. Artuk's sons and descendants ruled the three branches in the region: Sökmen's descendants ruled the region around Hasankeyf between 1102 and 1231; Ilghazi's branch ruled from Mardin and Mayyafariqin between 1106 and 1186 (until 1409 as vassals) and Aleppo from 1117–1128; and the Harput line starting in 1112 under the Sökmen branch, and was independent between 1185 and 1233. History The dynasty was founded by Artuk, son of Eksük, a general originally under Malik-Shah I and then under the Seljuk emir of Damascus, Tutush I.
