Miningi imibono ewela ezingqondweni zethu nganoma yiluphi usuku olunikeziwe, ake ucabange ukuthi ngaphezu kwalokhu ubenenhlanhla ngokwanele ukuba ukwazi ukukufeza njengoba unengqalasizinda edingekayo nezezimali. Lokhu yikho kanye okwenzekile kufayela le- University of Washington lapho iqembu labacwaningi belisebenza khona izinyanga ngendlela entsha, eyinqayizivele yokushaja okungenantambo.
Njengoba ukwazi ukubona esithombeni esiphezulu salokhu okuthunyelwe, sikhuluma ngomsebenzi oholele ekwakhiweni kobunye iphedi yokushaja engenantambo okuvelele kokunye okusele kukhona emakethe ngeqiniso elilula lokuthi, ukushaja ifoni yakho, isebenzisa ngqo i i-laser, indlela ethokozisayo esetshenziswa ukuthumela amandla kusuka kolunye uhlangothi lwelinye igumbi iye kolunye.
Ishaja ye-laser ingashesha njengokusebenzisa ikhebula le-USB lendabuko
Ukulandela amagama onjiniyela nabaphenyi abasebenze kule phrojekthi, ngemuva kwezinyanga ezimbalwa besebenza futhi benza ngcono imiphumela etholakele ezivivinyweni ezahlukahlukene, kubonakala sengathi ukushaja idivayisi esebenzisa i-laser ngokushesha nje ngokusebenzisa ikhebuli elijwayelekile lendabuko le-USB. Phakathi kwezinzuzo zokusebenzisa leplatifomu sithola ukuthi ukusetshenziswa kwayo kuphephe ngokuphelele.
Ngokwami, kufanele ngivume ukuthi intuthuko nakho konke okufeziwe ngokuqaliswa kwale nkundla kungihehile, noma kunjalo, ngokushaja amadivayisi eselula njenge-smartphone, ngiyakubona okungadingekile Ngoba lezi zinhlobo zamacala akhona sezivele zitholakala emakethe isikhathi esithile futhi, namuhla, ngisho nawo wonke amatheminali aphezulu afaka lolu hlobo lobuchwepheshe, into kuzokwenza kube nzima kakhulu ukuthi le shaja ye-laser ikwazi ukuphoqelela.
Yize intshisekelo yephrojekthi, inkinga yokuthi, ukushaja idivayisi, kufanele ibekwe endaweni ethile ayikaxazululwa
Naphezu kwakho konke lokhu, iqiniso ukuthi kuyinto ethokozisayo ukuthi leli qembu lonjiniyela likwazile ukwenza uhlelo olukwazi ukusebenzisa i-laser beam ukwenza ukudluliswa kwamandla kusuke endaweni eyodwa kuye kwenye. Njengoba kushiwo ephepheni elishicilelwe yilabo ababhekele le phrojekthi, ishaja yayo engenantambo eyingqayizivele isebenzisa iseli elincane lamandla okufanele itholakale ngemuva kwe-smartphone. Ngenxa yalokhu, i-laser emitter eyakhelwe ukukhiqiza umuthi oseduze we-infrared, ophethe ukwenza ukuthi idivayisi iqale ukukhokhisa.
Njengoba kungenzeka ukuthi uke wezwa ngezikhathi ezithile, lolu hlobo lokukhanya lunenkinga ngalokhu kusetshenziswa nokuthi yilokho kuphela kukhiqiza ukushisa okuningi y kungaba yingozi okomuntu. Ngenxa yalokhu, lolu gongolo luzungezwe uhlelo olulula kakhulu noluyisisekelo lwamalambu e-laser angenabungozi ngokuphelele, okungenzeka, njengoba kungenzeka ucabanga, abe nokusebenza okukhethekile kokucima i-laser yokushaja nganoma yisiphi isikhathi. Ngokuningiliziwe, engeza ukuthi leli thimba lonjiniyela belikade lisebenza ohlelweni olukwazi ukusabalalisa ukushisa ukuvikela amadivayisi ukuthi angafiki emazingeni okushisa aphezulu kakhulu.
Ngamazwi ka Shyam Gollakota, umbhali osebenza naye walolu cwaningo:
Imishayo yokuvikela ingenza ngokushesha ukwedlula ukunyakaza kwethu okusheshayo. Lapho ugongolo lokuphepha luphazanyiswa ukunyakaza komuntu, umthumeli uluthatha engxenyeni yesekhondi bese ethumela isivalo ukuvimba ugongolo lokushaja ngaphambi kokuba umuntu ahlangane nalo.
Njengemininingwane yokugcina, vele ukutshele ukuthi ngesikhathi sokuhlolwa okwenziwe yithimba, a amandla ahlala njalo ka-2 W endaweni engaba ngu-40 cm2 ukusuka ebangeni elifinyelela kumamitha angu-4. Kungenzeka ukuguqula okukhiphayo ukuze wandise irediyasi yokukhanya kokushaja iye endaweni ebanzi kakhulu engafinyelela ku-100 cm2 kusuka ebangeni lamamitha ayi-12.
