Kukho iingcamango ezininzi eziwela iingqondo zethu ngalo naluphi na usuku, cinga ukuba, ukongeza koku, ube nethamsanqa ngokwaneleyo ukuba ukwazi ukuphumeza ngenxa yokuba uneziseko eziyimfuneko kunye nenkxaso-mali. Yile nto kanye eyenzekileyo kwi Yunivesithi yaseWashington apho iqela labaphandi lisebenze iinyanga kwindlela entsha, engaqhelekanga, yokutshaja ngaphandle kwamacingo.
Njengoko unokubona kumfanekiso obekwe entlokweni yolu ngeniso lunye, sithetha ngomsebenzi obangele ekudalweni kwento eyodwa. Iphedi yokutshaja engenazingcingo leyo ibalasele kwezinye esele zikhona kwimarike ngenyaniso elula yokuba, ukuhlawulisa isixhobo sakho esiphathwayo, sisebenzisa ngokuthe ngqo I-laser, indlela enomdla kakhulu esetyenziselwa ukuthumela amandla ukusuka kwelinye icala lalo naliphi na igumbi ukuya kwelinye.
Le tshaja ye-laser inokukhawuleza njengokusebenzisa intambo ye-USB yemveli
Ngokwamazwi eenjineli kunye nabaphandi abaye basebenza kule projekthi, emva kweenyanga ezininzi zokusebenza kunye nokuphucula iziphumo ezifunyenwe kwiimvavanyo ezahlukeneyo, kubonakala ngathi baye bafezekisa ukuba ukutshaja isixhobo usebenzisa i-laser. ngokukhawuleza njengokusebenzisa intambo ye-USB eqhelekileyo. Phakathi kweenzuzo zokusebenzisa eli qonga sifumanisa ukuba ukusetyenziswa kwayo kukhuselekile ngokupheleleyo.
Ngokomntu, kufuneka ndivume ukuba uphuhliso kunye nayo yonke into ephunyeziweyo ngokuphunyezwa kweli qonga liye labamba ingqalelo yam, nangona, ngokuchanekileyo ukutshaja izixhobo eziphathwayo ezifana ne-smartphone, ndiyayibona. kancinci okungafunekiyo Ngenxa yokuba ezi ntlobo zemithwalo sele zifumaneka kwimarike ixesha elide kwaye, namhlanje, nazo zonke iitheminali eziphezulu zibandakanya olu hlobo lwetekhnoloji, into iya kwenza kube nzima kakhulu kule tshaja yelaser ukuba iphumelele.
Nangona uhlobo olunomdla lweprojekthi, ingxaki yokuba, ukuhlawulisa isixhobo, kufuneka ibekwe kwindawo ethile ayikasonjululwa.
Ngaphandle kwayo yonke le nto, inyaniso kukuba inomdla ngakumbi ukuba eli qela leenjineli likwazile ukuphuhlisa inkqubo ekwaziyo ukusebenzisa i-laser beam ukuhambisa amandla ukusuka kwenye indawo ukuya kwenye. Njengoko kuchaziwe kwiphepha elipapashwe ngabo banoxanduva lweprojekthi, itshaja yayo ekhethekileyo engenazingcingo yenza ukusebenzisa iseli yamandla ebhityileyo ekufuneka ibekwe ngasemva kwi-smartphone. Ngombulelo koku, i-laser emitter elungiselelwe ukuvelisa i-infrared beam ekufutshane inoxanduva lokwenza isixhobo siqale ukutshaja.
Njengoko uvile ngokuqinisekileyo ngesinye isihlandlo, olu hlobo lokukhanya lune-drawback kolu setyenziso kwaye lulo yenza ubushushu obuninzi y kunokuba yingozi emntwini. Ngenxa yoku, lo mtha ujikelezwe yinkqubo elula kakhulu kwaye esisiseko yamandla aphantsi, izibane ze-laser ezingenabungozi ngokupheleleyo, ezithi, njengoko unokucinga, zibe nomsebenzi okhethekileyo wokucima i-laser yokutshaja ngexesha elithile. Njengenkcukacha, yongeza ukuba eli qela leenjineli likwasebenza kwinkqubo ekwaziyo ukukhupha ubushushu ukuthintela izixhobo ekufikeleleni kumaqondo obushushu aphezulu kakhulu.
Ngamazwi e Shyam Gollakota, umbhali-mlingane wolu phononongo:
Imiqadi yokhuseleko inokusebenza ngokukhawuleza kuneentshukumo zethu ezikhawulezayo. Xa umqadi wokhuseleko uphazamiseka yintshukumo yomntu, i-emitter ibona oku kwiqhezu lesibini kwaye ifake i-shutter ukuvala umqadi wentlawulo ngaphambi kokuba umntu adibane nayo.
Njengeenkcukacha zokugqibela, ndinokuxelela kuphela ukuba ngexesha lovavanyo olwenziwe liqela kwakunokwenzeka ukuhambisa a amandla ahlala e-2 W kwindawo emalunga ne-40 cm2 ukusuka kumgama ukuya kwi-4 yeemitha. Kunokwenzeka ukuguqula i-emitter ukwandisa i-radius yokukhanya okutshajayo kwindawo enkulu kakhulu enokufikelela kwi-100 cm2 ukusuka kumgama weemitha ezili-12.
