81-542: Japan Remote Control Co., Ltd. (日本遠隔制御株式会社; Nippon Enkaku Seigyo Kabushiki Gaisha ) (commonly called source Propo, source Racing, or hum) was a Japanese manufacturer of popular radio control devices including transmitters , receivers , servos , electronics, programmable robots and model aircraft . JR has ceased production of RC equipment. Unique to JR Propo's radios is the company's patented ABC&W technology, or Automatic Blocking Circuit with Window. Simply put, this system rapidly reroutes incoming signals through

162-546: A sex addiction . In the Royal Library of Madrid , there are books containing emblems of the Spanish monarch. Alfonso XIII is a rare example of endogamy . In the eleventh generation he is assumed to only have 111 ancestors whereas in a standard situation one expects to identify 1024 of them, a situation of implex of 89%. The biological paternity of Alfonso's father Alfonso XII on the part of Francisco de Asís

243-416: A Catholic, anti-Catalanist , dictatorial and militarist brand of Spanish nationalism. On 28 January 1930, amid economic problems, general unpopularity and a putschist plot led by General Manuel Goded in motion, of which Alfonso XIII was most probably aware, Miguel Primo de Rivera was forced to resign, exiling to Paris, only to die a few weeks later of the complications from diabetes in combination with

324-536: A Nobel Prize. Alfonso XIII was born at the Royal Palace of Madrid on 17 May 1886. He was the posthumous son of Alfonso XII of Spain, who had died in November 1885, and became king upon his birth. Just after he was born, he was carried naked to the prime minister Práxedes Mateo Sagasta on a silver tray. Five days later, he was carried in a solemn court procession with a Golden Fleece around his neck and

405-697: A couple thousand dollars , all the way down to under US$ 30 for some. Some manufacturers even offer conversion kits for older digital 72 MHz or 35 MHz receivers and radios. As the emerging multitude of 2.4 GHz band spread spectrum RC systems usually use a "frequency-agile" mode of operations, like FHSS that do not stay on one set frequency any longer while in use, the older "exclusive use" provisions at model flying sites needed for VHF-band RC control systems' frequency control, for VHF-band RC systems that only used one set frequency unless serviced to change it, are not as mandatory as before. Remote control military applications are typically not radio control in

486-512: A human operator. An industrial radio remote control can either be operated by a person, or by a computer control system in a machine to machine (M2M) mode. For example, an automated warehouse may use a radio-controlled crane that is operated by a computer to retrieve a particular item. Industrial radio controls for some applications, such as lifting machinery, are required to be of a fail-safe design in many jurisdictions. Industrial remote controls work differently from most consumer products. When

567-514: A majority of councillors overall, won a sweeping majority in major cities in the 1931 municipal elections , which were perceived as a plebiscite on monarchy. The results shocked the government, with foreign minister Romanones admitting to the press an "absolute monarchist defeat" and Civil Guard honcho José Sanjurjo reportedly telling government ministers that, given circumstances, the Armed Forces could not be "absolutely" relied upon for

648-461: A minimum of three control dimensions (yaw, pitch and motor speed), as opposed to boats, which required only two or one. As the electronics revolution took off, single-signal channel circuit design became redundant, and instead radios provided proportionally coded signal streams which a servomechanism could interpret, using pulse-width modulation (PWM). More recently, high-end hobby systems using pulse-code modulation (PCM) features have come on

729-535: A number of commando raids to collect the missile radio sets. Jammers were then installed on British ships, and the weapons basically "stopped working". The German development teams then turned to wire-guided missiles once they realized what was going on, but the systems were not ready for deployment until the war had already moved to France. The German Kriegsmarine operated FL-Boote ( ferngelenkte Sprengboote ) which were radio controlled motor boats filled with explosives to attack enemy shipping from 1944. Both

810-526: A number of different relays when a particular frequency was received. The relays would in turn then activate various actuators acting on the control surfaces of the missile. The controller's radio transmitter would transmit the different frequencies in response to the movements of a control stick; these were typically on/off signals. The radio gear used to control the rudder function on the American-developed Azon guided ordnance, however,

891-673: A plebiscite on maintaining the monarchy or declaring a republic – the result of which led to the proclamation of the Second Spanish Republic on 14 April 1931. His efforts with the European War Office during World War I earned him a nomination for the Nobel Peace Prize in 1917, which was ultimately won by the Red Cross . To date, he remains the only monarch known to have been nominated for

At an 1898 exhibition at Madison Square Garden , Nikola Tesla demonstrated a small boat that used a coherer -based radio control. With an eye towards selling the idea to the US government as a torpedo, Tesla's 1898 patent included a clockwork frequency changer so an enemy could not take control of

1053-770: A receiver there are usually several relays, and in something as complex as an overhead crane, perhaps up to twelve or more relays are required to control all directions. In a receiver which opens a gate, two relays are often sufficient. Industrial remote controls are getting more and higher safety requirements. For example: a remote control may not lose the safety functionality in case of malfunction. This can be avoided by using redundant relays with forced contacts. Alfonso XIII Alfonso XIII ( Spanish : Alfonso León Fernando María Jaime Isidro Pascual Antonio de Borbón y Habsburgo-Lorena ; French : Alphonse Léon Ferdinand Marie Jacques Isidore Pascal Antoine de Bourbon ; 17 May 1886 – 28 February 1941), also known as El Africano or

1134-539: A series of ever-smaller electronic "windows," effectively blocking out spurious signals which cause radio "glitching". Any signal that does get through the system is filtered before being sent to the servos all without noticeable lag or delay. If the signal is unable to be processed, it is rejected, again without noticeable reaction. Competing brands of radio control systems include, Spektrum RC , Sanwa , Futaba , Hitec, KO Propo , Jeti , Acoms and Multiplex Modelsport . This article on an unmanned aerial vehicle

1215-644: A sign that the King was indifferent over the lives of his soldiers. In 1922, the Cortes started an investigation into the responsibility for the Annual disaster and soon discovered evidence that the King had been one of the main supporters of Silvestre's advance into the Rif mountains. After the "Disaster of the Annual", Spain's war in the Rif went from bad to worse, and as the Spanish were barely hanging on to Morocco, support for

1296-710: A strict constitutional monarch, and supported the Africanists who wanted to conquer for Spain a new empire in Africa to compensate for the lost empire in the Americas and elsewhere. The Rif War had starkly polarized Spanish society between the Africanists who wanted to conquer an empire in Africa vs. the abandonistas who wanted to abandon Morocco as not worth the blood and treasure. Alfonso liked to play favourites with his generals, and one of his most favoured generals

1377-582: A target otherwise both difficult and dangerous to attack. However, by the end of the war, the Luftwaffe was having similar problems attacking Allied bombers and developed a number of radio command guided surface-to-air anti-aircraft missiles , none of which saw service. The effectiveness of the Luftwaffe 's systems, primarily comprising the series of Telefunken Funk-Gerät (or FuG) 203 Kehl twin-axis, single joystick-equipped transmitters mounted in

1458-551: A vehicle are the Mars Exploration Rovers such as Sojourner . Today radio control is used in industry for such devices as overhead cranes and switchyard locomotives . Radio-controlled teleoperators are used for such purposes as inspections, and special vehicles for disarming of bombs . Some remotely controlled devices are loosely called robots , but are more properly categorized as teleoperators since they do not operate autonomously, but only under control of

1620-592: The turno system, the deepening of the Restoration system crisis in the 1910s, a trio of crises in 1917 , the spiral of violence in Morocco and, especially, the lead-up to the 1923 installment of the dictatorship of Miguel Primo de Rivera , an event that succeeded by means of both military coup d'état and the king's acquiescence. Over the course of his reign, the monarch ended up favouring an authoritarian solution rather than constitutional liberalism. Upon

1701-546: The Africanists comprising only a minority, it was clear that it was only a matter of time before the abandonistas forced the Spanish to give up on the Rif, which was part of the reason for the military coup d'état later in 1923 . On 13 September 1923, Miguel Primo de Rivera , Captain General of Catalonia, staged a military coup with the collaboration from a quad of Africanist generals based in Madrid who were associated to

1782-536: The City Council of Madrid dedicated in 2003 to Ratoncito Pérez on the second floor of number eight of Calle del Arenal  [ es ] , where the mouse was said to have lived. Alfonso and his wife Princess Victoria Eugenie of Battenberg (Ena) had seven children: Alfonso also had a number of reported illegitimate children that are known, including: Alfonso was known for his friendly attitude towards Jews and publicly praised them. In 1932, he embraced

1863-621: The Judeo-Masonic-Communist conspiracy theory . He took several actions to offer them protection. In 1917, Alfonso instructed the Spanish consul in Jerusalem , Antonio de la Cierva y Lewita, Count of Ballobar, to help protect Palestinian Jews . On another occasion, after a high official in Tetuan had committed onslaughts against Jews, a delegation composed of Catholics, Jews, and Muslims appealed to Alfonso. The King then removed

1944-571: The abandonistas grew as many people could see no point to the war. In August 1923, Spanish soldiers embarking for Morocco mutinied, other soldiers in Málaga simply refused to board the ships that were to take them to Morocco, while in Barcelona huge crowds of left-wingers had staged anti-war protests at which Spanish flags were burned while the flag of the Rif Republic was waved about. With

2025-517: The de Havilland " Tiger Moth " aircraft for Navy fleet gunnery firing practice. The "Queen Bee" was superseded by the similarly named Airspeed Queen Wasp , a purpose-built target aircraft of higher performance. Radio control was further developed during World War II, primarily by the Germans who used it in a number of missile projects. Their main effort was the development of radio-controlled missiles and glide bombs for use against shipping,

2106-462: The dictatorship of Primo de Rivera that it was difficult for him to distance himself from the regime that he had supported for almost seven years. The enforced changes relied on the incorrect assumption that Spaniards would accept the notion that nothing had happened after 1923 and that going back to the prior state of things was possible. On 12 April, the Republican coalition, short of winning

2187-597: The execution of the Romanov family , but was mistaken in believing that only Nicholas II and his son Alexei had been killed. As such, he continued to push for the Tsarina Alexandra and her four daughters to be brought to Spain, not having realized that they had also been murdered. Alfonso became gravely ill during the 1918 flu pandemic . Spain was neutral and thus under no wartime censorship restrictions, so his illness and subsequent recovery were reported to

2268-489: The steering engine and different velocities for the propelling engine independently, and also to act over other mechanisms such an electric light , for switching it, and a flag , for raising or dropping it, at the same time, and so up to 19 different actions. In 1904, Torres chose to carry out the first test on a three-wheeled land vehicle with a range of 20 to 30 meters. In 1906, in the presence of an audience which included King Alfonso XIII of Spain, Torres demonstrated

2349-440: The 'on/off' type, Torres established a system for controlling any mechanical or electrical device with different states of operation. This method required a transmitter capable of sending a family of different code words by means of a binary telegraph key signal, and a receiver, which was able to set up a different state of operation in the device being used, depending on the code word. It was able to select different positions for

2430-489: The African due to his Africanist views , was King of Spain from his birth until 14 April 1931, when the Second Spanish Republic was proclaimed. He became a monarch at birth as his father, Alfonso XII , had died the previous year. Alfonso's mother, Maria Christina of Austria , served as regent until he assumed full powers on his sixteenth birthday in 1902. Alfonso XIII's upbringing and public image were closely linked to

2511-542: The Barcelona production company Royal Films , with the Count of Romanones acting as an intermediary figure between him and the company. Between forty and seventy pornographic films are said to have been shot in total (three of which have been preserved) and were screened in Barcelona's Chinatown , as well as during Alfonso's private screenings. The films, while silent and in black and white, were nonetheless very explicit for

2592-744: The British and US also developed radio control systems for similar tasks, to avoid the huge anti-aircraft batteries set up around German targets. However, no system proved usable in practice, and the one major US effort, Operation Aphrodite , proved to be far more dangerous to its users than to the target. The American Azon guided free-fall ordnance, however, proved useful in both the European and CBI Theaters of World War II. Radio control systems of this era were generally electromechanical in nature, using small metal "fingers" or " reeds " with different resonant frequencies each of which would operate one of

The tradition of Ratoncito Pérez replacing the lost milk teeth with a small payment or gift while the child sleeps is almost universally followed today in Spain and Hispanic America. Alfonso XIII is also mentioned on the plaque that

His health deteriorated around 10 January 1890, and doctors reported his condition as the flu attacked his nervous system leaving the young king in a state of indolence. He eventually recovered. When Alfonso came of age in May 1902, the week of his majority

2835-600: The Spanish diplomatic and military network abroad to intercede for thousands of POWs – transmitting and receiving letters for them, and other services. The office was located in the Royal Palace . Alfonso attempted to save the Russian Tsar Nicholas II and his family from the Bolsheviks who captured them, sending two telegrams offering the Russian imperial family refuge in Spain. He later learned of

Alfonso was a promoter of tourism in Spain. The need for the lodging of his wedding guests prompted the construction of the luxurious Hotel Palace in Madrid. He also supported the creation of a network of state-run lodges, Paradores , in historic buildings of Spain. His fondness for

2997-764: The Tetuan official from power, in spite of the fact that the official possessed the support of the Spanish Minister of Foreign Affairs . According to the Jewish Professor Abraham S.E. Yahuda, Alfonso told Yahuda in private conversations that he would issue no policies of discrimination towards Jews, believing all of his Spanish subjects to be entitled to equal rights and protection. Alfonso is occasionally referred to as "the playboy king", due in part to his promotion and collection of Spanish pornographic films, as well as his extramarital affairs. As King, Alfonso commissioned pornographic films through

3078-447: The accuracy of torpedoes for military purposes) predates the invention of radio. The latter half of the 1800s saw development of many such devices, connected to an operator by wires, including the first practical application invented by German engineer Werner von Siemens in 1870. Getting rid of the wires via using a new wireless technology, radio, appeared in the late 1890s. In 1897 British engineer Ernest Wilson and C. J. Evans patented

3159-536: The agreement of marriage. Alfonso and Victoria were married at the Royal Monastery of San Jerónimo in Madrid on 31 May 1906, with British royalty in attendance, including Victoria's cousins the Prince and Princess of Wales (later King George V and Queen Mary ). The wedding was marked by an assassination attempt on Alfonso and Victoria by Catalan anarchist Mateu Morral. As the wedding procession returned to

3240-582: The command of Eric Robinson V.C. used a variant of the Aerial Target’s radio control system to control from ‘mother’ aircraft different types of naval vessels including a submarine. During World War I American inventor John Hays Hammond, Jr. developed many techniques used in subsequent radio control including developing remote controlled torpedoes, ships, anti-jamming systems and even a system allowing his remote-controlled ship targeting an enemy ship's searchlights. In 1922 he installed radio control gear on

3321-478: The condition. Alfonso distanced himself from his wife for transmitting the condition to their sons. From 1914 on, he had several mistresses, and fathered five illegitimate children. A sixth illegitimate child had been born before his marriage. During World War I , because of his family connections with both sides and the division of popular opinion, Spain remained neutral. The King established an office for assistance to prisoners of war on all sides. This office used

3402-629: The current requirements at low voltage were greatly reduced and the high voltage battery was eliminated. In both tube and early transistor sets the model's control surfaces were usually operated by an electromagnetic ' escapement ' controlling the stored energy in a rubber-band loop, allowing simple on/off rudder control (right, left, and neutral) and sometimes other functions such as motor speed. Crystal-controlled superheterodyne receivers with better selectivity and stability made control equipment more capable and at lower cost. Multi-channel developments were of particular use to aircraft, which really needed

The debate ended with an eloquent speech by Prime Minister Manuel Azaña pleading for the unanimity of the house "to condemn and exclude D. Alfonso de Borbón from the law, proclaiming the majesty of our republic,

In Spain, dictator Francisco Franco ordered three days of national mourning. The ex-king's funeral was held in Rome in the Church of Santa Maria degli Angeli e dei Martiri . He was buried in the Church of Santa Maria in Monserrato degli Spagnoli ,

3645-532: The democratically elected Republican government a war broke out in Spain . On 30 July 1936, Alfonso's son Juan took the initiative of leaving Cannes to go to Spain to join the rebel faction , with the former king (then in a hunting trip in Czechoslovakia ) reportedly giving consent, so Juan de Borbón crossed the border set to join the front in Somosierra dressed in a blue jumpsuit and red beret under

After initial successes, the British launched

3807-459: The dethroned king likewise accusing in the document the reformist Republic to be " inspired and sponsored by communism, freemasonry and judaism ". In 1933, his two eldest sons, Alfonso and Jaime, renounced their claims to the defunct throne on the same day, and in 1934 his youngest son Gonzalo died. This left his third son Juan his only male heir. After the July 1936 attempted coup d'état against

3888-491: The device. In 1903, the Spanish engineer Leonardo Torres Quevedo introduced a radio based control system called the " Telekino " at the Paris Academy of Sciences . In the same year, he applied for several patents in other countries. It was intended as a way of testing Astra-Torres airship , a dirigible of his own design, without risking human lives. Unlike the previous mechanisms, which carried out actions of

Instead of a "turn left" signal that is applied until the aircraft is flying in the right direction, the system sends a single instruction that says "fly to this point". Some of the most outstanding examples of remote radio control of

4050-490: The effects of a flu . Alfonso XIII appointed General Dámaso Berenguer as the new prime minister. Back in 1926, Alfonso XIII had appointed Berenguer as Chief of Staff of the Military House of the King, a post conventionally fit for burned-out generals in order to move them away from the spotlight for a time in a show of affection. The new period was nicknamed as dictablanda . The King was so closely associated with

4131-456: The fake name "Juan López". However, rebel general Emilio Mola , mastermind behind the putschist plot, was warned of the move and had Juan returned. The former king made it clear he favoured the rebel faction against the Republican government. In September 1936, the general who had emerged as leader of the rebel faction, Francisco Franco , declared that he would not restore Alfonso as king. On 15 January 1941, Alfonso XIII renounced his rights to

In the early 21st century, 2.4 gigahertz spread spectrum RC control systems have become increasingly utilized in control of model vehicles and aircraft. Now, these 2.4 GHz systems are being made by most radio manufacturers. These radio systems range in price from

4293-442: The innermost military clique of Alfonso XIII and who wanted to prevent investigations about Annual from tarnishing the monarch (José Cavalcanti, Federico Berenguer, Leopoldo Saro and Antonio Dabán), even if Primo de Rivera had embraced Abandonista positions prior to that point. Primo de Rivera ruled as a dictator with the king's support until January 1930. During the dictatorship, the king increased his public presence, siding with

4374-514: The invention in the Port of Bilbao , guiding the electrically powered launch Vizcaya from the shore with people on board, which was controlled at a distance over 2 km. In 1904, Bat , a Windermere steam launch, was controlled using experimental radio control by its inventor, [Jack Kitchen]. In 1909 French inventor [Gabet] demonstrated what he called his " Torpille Radio-Automatique ", a radio-controlled torpedo. In 1917, Archibald Low , as head of

However, even with this coding, loss of transmission during flight has become more common , in part because of the ever more wireless society. Some more modern FM-signal receivers that still use "PWM" encoding instead can, thanks to the use of more advanced computer chips in them, be made to lock onto and use

4617-440: The military estate; he often presented himself as a soldier-king. His effective reign started four years after the Spanish–American War , when various social milieus projected their expectations of national regeneration onto him. Like other European monarchs of his time he played a political role, entailing a controversial use of his constitutional executive powers. His wedding to Princess Victoria Eugenie of Battenberg in 1906

Reportedly, Alfonso's response to the news was to shrug his shoulders and say "Chicken meat is cheap", before resuming his game. Alfonso remained in France and did not return to Spain to comfort the families of the soldiers lost in the battle, which many people at the time saw as a callous and cold act,

Selected others include Real Madrid , Real Sociedad , Real Betis , Real Unión , Espanyol , Real Zaragoza and Real Racing Club . An avenue in the northern Madrid neighbourhood of Chamartín, Avenida de Alfonso XIII, is named after him. A plaza or town centre in Iloilo City , Philippines (now Plaza Libertad)

5427-618: The sustainment of the monarchy. Alfonso XIII fled the country and the Second Spanish Republic was peacefully proclaimed on 14 April 1931. In November 1931, the Constituent Republican Cortes held an impassionate debate about the political responsibilities of the former monarch. Some of the grievances against the action of Alfonso XIII as a king included interference in the institutions to reinforce his personal power, bargaining personal support from

5508-408: The time, showing full nudity and sex scenes. These films featured content considered immoral and degenerate, including sexual relationships involving Catholic priests, lesbianism, and "women with enormous breasts" (the last of which is said to have been Alfonso's passion). Most of these films were later destroyed during Franco's regime . This has led some to speculate that Alfonso may have possessed

5832-571: The world, while flu outbreaks in the belligerent countries were concealed. This gave the misleading impression that Spain was the most affected area and led to the pandemic being dubbed "the Spanish Flu". Following World War I, Spain entered the lengthy yet victorious Rif War (1920–1926) to preserve its colonial rule over northern Morocco. Critics of the monarchy thought the war was an unforgivable loss of money and lives, and nicknamed Alfonso el Africano ("the African"). Alfonso had not acted as

5913-511: Was Manuel Fernández Silvestre . In 1921, when Silvestre advanced up into the Rif mountains of Morocco, Alfonso sent him a telegram whose first line read "Hurrah for real men!", urging Silvestre not to retreat at a time when Silvestre was experiencing major difficulties.
