The napedyo Switch pafoni - chii? maserura

Yakatarwa hwemazuva zvemagetsi zvigadzirwa vakapakata sensors kuti vanoziva nzira yaJehovha chinhu, semuenzaniso, munwe, mumwe kiibhodhi kana munhu nzeve kuti foni. Michina iyi zvinowanzoshandiswa kubatwa ukomba akasiyana-siyana, izvo hakubvisi zvokuimba nokuchinja mano uye achawedzera upenyu hwavo basa. Uye vazhinji zvinogona kukumbirwa: a napedyo Switch pafoni - chii uye sei kushanda? mudziyo uyu ichakurukurwa hereinafter maererano Implementation pamusoro capacitive rwokugadzira.

pamutemo kusvika

Recognition rakada contactless michina inokurumidza akawana kushanda mumunda inotakurika mano dzinofambiswa tisingatungamirirwi. Mashandiro ari zvinowanzoshandiswa matsva yemashoko smartphones uye mahwendefa, mimhanzi vatambi. Chinangwa charo chikuru ndiko kuwedzera rakavimbika Namano uye rokuponesa magetsi simba.

The Kuratidzwa chikwata chichange deactivated sokuvapo nzira iri kuona ruoko rokushandisa, zviri basa nayo uye napedyo Switch iri pafoni yako. Chii - zvichava pachena kana tikaongorora nheyo huchishanda. Kana totaura kushandiswa kwemichina kwakadaro, pano zvinokosha kuziva kuti mune standby muoti simba rakawanda riri vaiita chete nechepakati processor. Kana napedyo sensors kuona tinosvika muchanza kana munwe, ari kuratidza zviri anobatidzwa, izvo zvinoratidza kuti mashoko ano. izvi zvose kunoderedza avhareji simba kuparadzwa Gadget, apo kuwedzera bhatiri Runtime.

Zvakakurukurwa kushandisa mashandiro anoita nzira dzakasiyana

The musha kushandisa michina napedyo vasabatwa kuchiitwa yakagamuchirawo zvakapararira zvikuru. Napedyo sensors zvinoshandiswa vakwanise tafura mwenje, okutanga mavharuvhu washer A, kana iri mumunda zviito zvavo ndiko rwomunhu; kuratidza sefiriji microwave yamavira achava basa kusvikira hazvingaswederi kuswedera ruoko rokushandisa. Zvaaishandisa pamwe basa iri, uye musha mutsva kushandisa michina hurongwa. Musabata sefa, kushandiswa kudzora mhuri midziyo yemagetsi uye chiedza, akamisa kushumira digital mufananidzo puranga. Asi sezvo nokukurumidza sezvazviri pedyo vamwe vanhu hwodoonekereswa kuzvidzora mabhatani. Enough dzinonakidza Michina ndiyo napedyo Switch iri pafoni yako. Chii zvinobatsira kunzwisisa rondedzero nzira naro Kuzivikanwa kunoitika.

Kuonekwa nzira nokuti approximating

Kune akawanda nzira, ramakagadzwa inductive, resistive, Manyiminya, capacitive, Manyiminya uye acoustical. Mumwe nomumwe wavo ane zvimwe zvakanakira nekuipira. The kusarudza zvemichina kunobva mari uye kudekara kushanda nayo. Funga napedyo Switch pafoni - kuchabatsira kunzwisisa zvimwe ruzivo. Kazhinji, ari capacitive napedyo sensors anoshandiswa. Pfungwa dzavo kushanda iri nyore. Switch conductors pamwe yakakodzera pacho, zvakavigwa pasi rwokudzivirira rukoko chaiyo. Two pakuitisa chinhu pedyo napedyo nepedyo, vane zvimwe capacitance rakarasika iyo unovapo pakati conductive rukoko uye grounding ikanyanya yacho Switch pachayo. Kazhinji zvayo yakawandisa 10-300 pikafarad.

Kana Switch iri kusvika Somuenzaniso, mumwe munwe, kuchinja zvinonyatsorehwa ino vanokwanisa. Rinoshandiswa kuziva chinhu pedyo asiri kuonana Switch.

Kuonekwa capacitance changed

Just sei yakarurama uye yakavimbika vasiri kuonana Switch zvinoshanda, zvinoenderana zvachose pamusoro inonyatsotaura kuyerwa pamusoro achinja vachikwanisa wegadziriro. Kuti zvidaro, yava akakudziridza nhamba nzira, kusanganisira zvakanakisisa anozivikanwa nzira simbi mutariri kuchinjirwa, anotevedzana rakada, nesungano pakati ngarava uye Sigma-Delta nzira. Kakawanda vaviri anoshandiswa. Vose vanoshandisa kushandisa capacitance redunhu uye kwokunze tambo capacitor.

The nzira zvinotevedzana approximations

Panyaya iyi, iyo uchiraira rinoitwa munhu kushandisa capacitor redunhu. Sezvo capacitor voltage rinoshandisirwa comparator kuburikidza pasi vanopfuura Sefa, umo zvichienzaniswa bhuku voltage. A pakaunda, clocked nokuda jenareta, yavharwa achishandisa comparator goho chiratidzo. Processing kuti chiratidzo ichi rinoitwa kuti imwe Switch mamiriro. kunyora nezvavo nhamba nechitarisiko zvinoriumba zvinodiwa nzira zvinotevedzana approximations. Panyaya iyi, dunhu oparesheni asingadi kukanganisa crosstalk panguva romugove cheni.

Zvakanakira nekuipira kuzivikanwa michina

Napedyo Switch Android, kufanana nevamwe, ane dzimwe dzose. Zvazvakanakira muchiitiko ichi ndeinotevera:

- chaizvo kuonekwa mapazi;

- refu mwero nehanya;

- hama Kuwanikwa tichitarisa mitengo, nekuti kweShanduro sensors chaizvo zvakachipa zvinoriumba - mhangura, tini oxide firimu, imwe indium ingi, ari kwokunze waya Switch;

- Small kukura;

- the pakawanda pakati magadzirirwo;

- tembiricha utsigo;

- kukwanisa kushanda nedzimwe non-conductive unhani Somuenzaniso, Girazi thicknesses siyana;

- mukurumari uye yakakwirira rakavimbika.

Pane ari nzira iyi ine matambudziko avowo:

- the vachifunga chinhu kuti conductive, ipapo achakwanisa kuona nzira; asi ruoko Somuenzaniso, mune imwe rabha gurovhisi, uye haagoni kuwana;

- kuwana kunharaunda conductive chinhu kungaita kuti hurongwa achaita recalculate kuti parasitic capacitance kuti kutora nyaya kuchinja anokonzerwa chinhu. Izvi Kazhinji mhosva okuzvidzivirira venhema ramangwana Zvisinei, napedyo Switch calibration ichabvisa chigumburo ichi;

- capacitive kuonekwa nzira inoshanda kuti kana kuwanda basa rake, pane zvinhu zvesimbi, kuwanda ipfupi.

Lock iPhone 4 sikirini

The napedyo Switch unoshanda kuitira unokubvumira chokukuvadza kuti smartphone chidzitiro panguva kufona kudzivisa netsaona anokosha nemichina. Kune anokosha mafomu kuti zvigoneke kukiya chidzitiro nokungoramba swiping pamusoro payo noruoko. Kuti ukwanise izvozvo, unofanira kumanikidza munhu Hardware bhatani.

calibration

Kazhinji, vanoishandisa nezvinoda risingafadzi mamiriro ezvinhu, apo chidzitiro zvechizarira kana kutaura haina kuitwa. Uye zvakare chinoitika kuti kuratidzwa rikasauya pamusoro pashure kudaidzwa yapera, ndokusaka dzenhare haisi kukiyiwa. Somuenzaniso, Nokia napedyo Switch haisi kushanda zvakanaka. Kugadzirisa dambudziko iri, rinoda calibrated. Kazhinji, vagadziri vakawanda vanoshandisa unyanzvi hwakasiyana-software kuti chinangwa ichi, izvo zvinogona kutorwa ari pamutemo Website.

Achangobuda shanduro Android 4, iyo calibration basa iri revatema mune Muterere. Kuti aite izvi, unofanira danda muzviruva, tsvaka chidzitiro, uye ipapo sarudza napedyo Switch Calibration. Mushure nokuvhara Switch ruoko kunge pahwindo inooneka, tinya OK. Dzimwe nguva akabvumira calibration uye pasina kuvhara Switch.
