Mbiri ya Remote Control

Kuwongolera kwakutali ndi chipangizo chotumizira opanda zingwe chomwe chimagwiritsa ntchito ukadaulo wamakono wokhotakhota wa digito kuyika zidziwitso zamabatani, ndikutulutsa mafunde opepuka kudzera pa infrared diode.Mafunde owala amasinthidwa kukhala ma siginecha amagetsi ndi wolandila infrared wa wolandila, ndipo amasinthidwa ndi purosesa kuti awonetse malangizo ofananirako kuti akwaniritse zofunikira pakuwongolera zida monga mabokosi oyika.

Mbiri ya Remote Control

Sizikudziwika kuti ndani adayambitsa njira yoyamba yoyendetsera kutali, koma imodzi mwazinthu zoyamba zakutali zinapangidwa ndi woyambitsa dzina lake Nikola Tesla (1856-1943) yemwe ankagwira ntchito kwa Edison ndipo ankadziwikanso kuti ndi katswiri wamaphunziro mu 1898 (US Patent No. 613809) ), yotchedwa "Njira ndi Zida Zowongolera Mayendedwe a Magalimoto kapena Magalimoto".

Kuwongolera koyambirira komwe kumagwiritsidwa ntchito poyang'anira kanema wawayilesi kunali kampani yamagetsi yaku America yotchedwa Zenith (yomwe tsopano idagulidwa ndi LG), yomwe idapangidwa m'ma 1950s ndipo poyambilira idalumikizidwa.Mu 1955, kampaniyo inapanga chipangizo chakutali chopanda zingwe chotchedwa "Flashmatic", koma chipangizochi sichingathe kusiyanitsa ngati kuwala kwa kuwala kumachokera kumtunda wakutali, komanso kumafunikanso kugwirizanitsa kuti ziwongoleredwe.Mu 1956, Robert Adler adapanga chowongolera chakutali chotchedwa "Zenith Space Command", chomwe chinalinso chida choyamba chamakono chowongolera opanda zingwe.Anagwiritsa ntchito ultrasound kuti asinthe mayendedwe ndi voliyumu, ndipo batani lililonse limatulutsa ma frequency osiyanasiyana.Komabe, chipangizochi chikhozanso kusokonezedwa ndi ultrasound wamba, ndipo anthu ena ndi nyama (monga agalu) amatha kumva phokoso lomwe limachokera ku remote control.

M'zaka za m'ma 1980, pamene zida za semiconductor zotumiza ndi kulandira kuwala kwa infuraredi zidapangidwa, pang'onopang'ono zidalowa m'malo mwa akupanga kuwongolera zida.Ngakhale njira zina zotumizira opanda zingwe monga Bluetooth zikupitilira kupangidwa, ukadaulo uwu ukugwiritsidwabe ntchito kwambiri mpaka pano.
