Taw keychain - tsheb ruaj ntseg system tswj txhais tau tias

Qhov tseem txhim khu kev qha txhais tau tias kev tiv thaiv lub tshuab los ntawm tawm tsam yog teev lub tswb. Muaj ntau cov tswv muaj resorted mus rau txoj kev no, nws yog, raws li lawv hais, pw tsaug zog peacefully. Lov tes taw, pab kom, reprogrammed ib tug tiv mechanism yuav pab tshwj xeeb tswb keychain uas los nrog txhua qhov system. Nws yog tsim los rau cov tsav tsheb hais kom kis tau tus mob mus rau ib tug central tswj tsev, uas nyob rau hauv lem decodes lub teeb liab thiab ua rau qhov hauj lwm.

Yuav ua li cas yog cov cim code ntawm tus yuam sij FOB?

Developers ntawm lub tsheb ruaj ntseg tshuab ua txhua yam los xyuas kom meej lub siab tshaj plaws kev ruaj ntseg rau lawv cov neeg muas zaub. Yog li ntawd, txhua thaj chaw deb tswj tswb nws muaj nws tus kheej cim code. Qhov no yuav pab kom tsis txhob muaj nyob sab nraum cuam thiab kom hais tias cov lwm yam ntaus ntawv yuav tsis muaj neeg xiam thiab re-kev pab cuam "signalization". Qhov no code yog generated thaum koj nias tej nyees khawm ntawm lub transmitter vaj tse nyob. Yog li rau ib lub tsheb yuav programmed rau ob peb hloov los yog ntxiv. Qhov no yog yam thaum lub "haiv neeg" tej thaj chaw deb tswj yog lawm los yog poob lawm.

Interestingly, lub manufacturers ntawm kev ruaj ntseg tshuab rau cov tsheb thiab lub tsheb tub sab yeej ib txwm sib tw nrog txhua lwm yam: thawj coj los mus ua kom cov code yooj yim decipher, thiab rau tom kawg, nyob rau hauv thiaj li yuav ntse tshaj plaw passwords. Nws yuav tsum tau muab sau tseg tias kev sib ntaus mus rau uas ua tau zoo. Thiab tam sim no muaj.

Transmitter Tsim: tsis cov teeb meem no?

Nws yog lub npe hu hais tias tus zoo nkauj tshaj plaws yog ntau npaum li cas qab ntxiag mus rau siv. Uas yog vim li cas ib co tuam txhab uas muag koom nyob rau hauv zus tau tej cov pib ruaj ntseg tshuab tiv thaiv tub sab tub nyiag, sim muab lub vaj huam sib luag tej yam txawv daim ntawv ntawm kev tswj. Piv txwv li, ib tsab coj ib tug boomerang los yog ib tug hourglass. Tab sis lub tseem ceeb nplhaib tswb Starline A-8 zoo heev li qub: ib tug duab plaub nrog ib tug me me kav hlau txais xov.

Muaj tsis muaj tsis ntseeg hais tias muaj ntau tuam txhab uas muag xav kom lawv cov khoom cim thiab ua raws li nws tau yooj yim coj style. Txawm li cas los ntawm lwm tus zoo, los ntawm txhua tej thaj chaw deb signaling muaj ib tug heev me me luaj li cas, yooj yim fits rau hauv lub Palm thiab nyhav xwb ib ob peb kaum ntawm grams. Qhov no ua rau nws raws li ib qho yooj yim mus use.

Ib co nta ntawm lub ntaus ntawv thiab cov lag luam ntawm trinkets

Qhov tseeb qauv ntawm cov transmitters yog feem ntau nruab nrog ib tug LCD zaub. Nws yog heev yooj yim, vim hais tias nws portrayed lub tsheb nws tus kheej, thiab nyob rau hauv ib co xwm txheej ceev qhov teeb meem no, koj yuav saib tau ib nrais muag raws nraim li cas tshwm sim rau lub tsheb. Qhov kev ncua deb ntawm uas tus signaling stick yuav ntse kis Pib ntsais koj teeb lub chaw tswj rau lub tswb system, nws txawv nyob ntawm seb tus qauv. Nyob rau hauv feem ntau nws nce mus txog ib tug tshaj plaws ntawm 50 m. Tsis tas li ntawd ua xws li hais tias "yeej" thiab 100 m.

Nyob rau hauv feem ntau, nws yog khiav keychain tswb los ntawm zoo tib yam roj teeb, uas yog ncha lub npe hu ua "me ntsis ntiv tes". Lawv yuav tsum hloov txog ib xyoos ib zaug. Ib txhia tej thaj chaw deb tswj ua qauv muaj ib tug tshwj xeeb uas qhia hais tias qhia tau hais tias cov qib uas yuav nqi. Qhov no yog theej yooj yim thiab yuav rhuav tshem qhov teeb meem no cia li tsis ua hauj lwm ntawm lub transmitter vim lub unsuitability ntawm lub roj teeb.
