I-proximity sensor on the phone - ntoni na? phones mobile

Isethi kweemveliso elektroniki mihla zixhotyiswe kunye nabenzi boluvo ababanikezelayo ingqalelo indlela bento, umz, umnwe, ikhibhodi okanye indlebe yabantu kwifowuni. Obu bugcisa sisetyenziswa ngokubanzi panels touch ezahlukahlukeneyo, nto leyo ishenxisa izixhobo utshintshe nje ngoomatshini nokulondoloza ubomi nenkonzo yabo. Kwaye abaninzi usenokuba wabuza: a isivamvo sakufutshane on the phone - yintoni na yaye isebenza njani? le sixhobo iza kuxoxwa koku malunga nokuphunyezwa kwi iteknoloji capacitive.

ukuqaphela indlela

Recognition isilinganiselo technology licwecwe ngokukhawuleza wafumana isicelo endle kwezixhobo eziphathwayo okunikwa ngokuzimeleyo. Umsebenzi lisetyenziswa kwi imifuziselo zakutshanje Smartphones nezidanga, xa abadlali umculo. Injongo yalo esentloko kukuba kukwandisa ukuthembeka izixhobo nokusindisa amandla ombane.

Iyunithi ukubonisa iya ingasebenzi nje indlela eshiyekileyo ifunyanwa esandleni lomntu, oko kuyisingatha kunye isivamvo sakufutshane kwifowuni yakho. Yintoni na yona - iya kucaca xa siqwalasela umgaqo osebenza ngayo. Xa kufikwa ukusetyenziswa kobugcisa enjalo, nantsi ke kubalulekile ukukhumbula ukuba ukusetyenziswa kwimo lwamandla yokulinda inxaxheba kuphela iprosesa engundoqo. Xa abenzi kufutshane ukuqinisekisa ukuba indlela entendeni okanye umnwe, isiboniso ivuliwe, ebonisa ulwazi yangoku. Konke oku kunciphisa umyinge ukusetyenziswa kwamandla igajethi, ngelixa sisenyusa sokusebenza ibhetri.

Iimpawu ukusetyenziswa kwemisebenzi iindlela ezahlukeneyo

Le isilawuli esizisebenzelayo sekhaya Ubhaqo proximity osemqoka wafumana yande kakhulu. abenzi boluvo kufutshane zisetyenziselwa ukwenza izibane itafile, izivingco lokuvula iqhoshana, xa kwinkalo yobuchule babo amanyathelo yesandla; iifriji ukubonisa kunye oveni microwave iya kuba isebenze de akayi kuza Sondeza esandleni lomsebenzisi. Esebenzisa lo msebenzi, yaye inkqubo entsha esizisebenzelayo sekhaya. Touch izikrini, kusetyenziswa ukulawula izixhobo zombane zasekhaya kunye nezibane, wamisa zikhonze njengesakhelo ifoto yasekhompyutheni. Kodwa kamsinya nje ikufuphi inxenye yabantu kubonakala kwangoko zokulawula. technology ezaneleyo umdla yeyona isivamvo sakufutshane kwifowuni yakho. Yintoni na kuyanceda ukuqonda inkcazelo ndlela ingqalelo kwenzeka.

iindlela nokubonwa for approximating

Kukho iindlela eziliqela, phakathi leyo ezenza ukuba, resistive, enombala, capacitive, enombala kunye acoustical. Ngamnye kubo kuneengenelo ezithile nezingalunganga. Ukukhethwa iteknoloji ixhomekeke iindleko kunye lula ukusebenza kuyo. Cinga proximity sensor on the phone - oko kuya kukunceda ukuqonda inkcazelo ethile. Kwiimeko ezininzi, nabenzi boluvo kufutshane capacitive zisetyenziswa. Umgaqo abasebenza ilula. abaqhubi woluvo kunye noko ezifanelekileyo, sifihlwe phantsi umaleko ekhethekileyo zokhuselo. Ezimbini ukuqhuba element kufutshane omnye komnye, abe capacitance ethile othuke leyo, phakathi umaleko conductive kwaye isisekelo pad womenzi woluvo ngokwayo. Ngokuqhelekileyo imali yayo 10-300 pikafarad.

Xa woluvo kuyeza, umzekelo, umnwe, utshintsho amandla kwinkqubo iyonke. Isetyenziswa ukubona into kufuphi woluvo non-contact.

Ubhaqo capacitance utshintsho

Nje indlela isivamvo non-contact ezichanekileyo oluthembekileyo iya kusebenza, oko kuxhomekeke kwi ukuthembeka womlinganiselo ngokutshintshwa kunako na kwinkqubo yemfundo. Ukuze senjenjalo, iye liqulunqe iindlela eziliqela, kuquka iindlela zentsimbi transfer ngongcono owaziwayo isigxina, isilinganiselo ilandelelana, impefumlelwano le nqanawa kunye nendlela sigma-nkanyamba. Amaninzi bobabini zisetyenziswa. Zombini sebenzisa ujikeleze capacitance ivuliwe kwaye zangaphandle lokulinganisa capacitor.

Indlela approximations ezilandelayo

Kulo mzekelo, ukutshaja lwenziwa ejikeleza capacitor watshintshela. Ekubeni ombane capacitor lisetyenziswa kwi comparator ngokusebenzisa filter asezantsi okuphumelela kwabafundi, apho kuthelekiswa reference ombane. A counter, clocked yi le generator, itshixiwe esebenzisa umqondiso comparator kwimveliso. Uqwalaselo Oluphawu ikhutshwa phandle ubume isivamvo ethile. Imbalwa kakhulu components lwangaphandle ezifunekayo indlela approximations ezilandelelanayo. Kulo mzekelo, umsebenzi wesiphaluka aluchaphazeli crosstalk kwi kwempahla.

Izinto eziluncedo nezingeloncedo kobuchwepheshe

Isivamvo sakufutshane Android, efana nabanye, awohluke ezithile. Izinto eziluncedo kulo mzekelo zimi ngolu hlobo lulandelayo:

- kakhulu ummandla ubhaqo;

- ngezinga eliphezulu uvakalelo;

- ukufumaneka isihlobo ngokwemiqathango kwamaxabiso, ngenxa yokuba kuveliswe le boluvo amacandelo kakhulu cheap - nobhedu, itoti oxide umboniso, i-inki indium, umenzi woluvo wire zangaphandle;

- ubukhulu Small;

- le nsimbi loyilo;

- uzinzo ubushushu;

- ukukwazi ukusebenza zokwaleka ezahlukeneyo non-conductive, umzekelo, iglasi nende ezahlukeneyo;

- iyahlala nokuthembeka eliphezulu.

Kukho le ndlela iye neengxaki ezithile:

- i element yokuqonda ukuba conductive, uya kwandula abe nako ukubona indlela; kodwa ke ngesandla, umzekelo, xa isikhuseli irabha, kwaye akanako ukufumana;

- ukufumana endhawini yo into conductive kunokubangela ukuba le nkqubo iza ekube- capacitance ekumfimfitheni ukuze uthathele ingqalelo utshintsho ukuba zibangelwa yi-into. Oku kudla unobangela ubala kwixesha elizayo, Noko ke, nesandi sidlalwe isivamvo sakufutshane uza kuphelisa le inkathazo;

- indlela capacitive Ubhaqo lusebenza ukuze xa uluhlu yomsebenzi wakhe, kukho izinto zesinyithi, uluhlu lifinyele.

Vala iPhone 4 screen

I-proximity sensor isebenza ukuze ikuvumela ukuba ukukhubaza smart screen ngethuba lokufowuna ukuthintela bokushicilela ngengozi iqhosha. Kukho izicelo ezizodwa ezenza kube lula ukutshixa ikhusi ngokuthi ku- nje phezu ngesandla. Ukuze isebenze, kufuneka cinezela iqhosha zekhompyutha.

Ukulinganiswa

Lidla abasebenzisi ezijongene isimo esibi, xa ukuvala isikrini xa bethetha akwenziwanga. Kwaye oko kwenzeka ukuba umboniso swi vula emva kokuba igqityiwe umnxeba, nto leyo esisizathu sokuba ifowuni ivulwe. Umzekelo, sensor Nokia sakufutshane ayisebenzi kakuhle. Ukuze kulungiswe le ngxaki, kufuneka ukuba lihlelwe. Ngokuqhelekileyo, abenzi abaninzi basebenzisa software ezikhethekileyo ngenxa yale njongo, nto leyo efumaneka kwi-website esemthethweni.

Iinguqulelo ezidlulileyo Android 4, umsebenzi umlinganiselo kwimibhobho kuthi kunxulunyaniswe kwi menu. Ukuze wenze oku, kufuneka ungene useto, khangela ikhusi, uze ukhethe isivamvo sakufutshane sandi. Emva yokuvala nengalo womenzi woluvo kufuneka ibe kwi window elivelayo, cofa ku Lungile. Ngamanye amaxesha ukuba ekulinganisweni kwaye ngaphandle sensor ukuvalwa.
