UMikhal Marek Uma ufuna ukwazi ukuthi isilinganiso sokushaya kwenhliziyo sisebenza kanjani nge-Apple Watch, ngokuqinisekile uzojabula idokhumenti entsha, echaza inqubo ngqo iwashi elikala ngayo ukushaya kwenhliziyo. Umbiko ucacisa inqubo yokulinganisa, imvamisa yayo kanye nezici ezingathinta kabi idatha.
Njengamanye ama-tracker amaningi okuqina, i-Apple Watch isebenzisa uhlelo lwama-LED aluhlaza ukukala izinga lokushaya kwenhliziyo, elithola ukushaya kwenhliziyo kusetshenziswa indlela ebizwa nge-photoplethysmography. Ukushaya ngakunye kuletha ukwanda kokugeleza kwegazi, futhi ngenxa yokuthi igazi limunca ukukhanya okuluhlaza, izinga lokushaya kwenhliziyo lingabalwa ngokulinganisa izinguquko ekumunceni kokukhanya okuluhlaza. Njengoba ukugeleza kwegazi endaweni ethile yomkhumbi kushintsha, ukudluliswa kwawo kokukhanya nakho kuyashintsha. Ngesikhathi sokuqeqeshwa, i-Apple Watch ikhipha ukukhanya okuluhlaza esihlakaleni sakho izikhathi eziyi-100 ngomzuzwana bese ikala ukumuncwa kwayo kusetshenziswa i-photodiode.
Uma ungaziqeqeshi, i-Apple Watch isebenzisa indlela ehluke kancane ukukala izinga lokushaya kwenhliziyo. Njengoba nje igazi limunca ukukhanya okuluhlaza, liphinde liphendule ekukhanyeni okubomvu. I-Apple Watch ikhipha ukukhanya kwe-infrared njalo ngemizuzu eyi-10 futhi iyisebenzisela ukukala ukushaya kwenhliziyo. Ama-LED aluhlaza abe esesebenza njengesixazululo esiyisipele uma kwenzeka imiphumela yezilinganiso kusetshenziswa ukukhanya kwe-infrared inganele.
Ngokusho kocwaningo, ukukhanya okuluhlaza kulungele ukusetshenziswa ku-photoplethysmography, njengoba ukulinganisa okusebenzisayo kunembe kakhulu. I-Apple ayichazi emibhalweni ukuthi kungani ingasebenzisi ukukhanya okuluhlaza kuzo zonke izimo, kodwa isizathu sisobala. Onjiniyela abavela eCupertino cishe bafuna ukonga amandla ewashi, elingachithi ngokuphelele.
Kunoma yikuphi, ukulinganisa ukushaya kwenhliziyo ngedivayisi egqokwe esihlakaleni akuthembeki ngo-100%, futhi i-Apple ngokwayo iyavuma ukuthi kwezinye izimo ukulinganisa kungase kube okungalungile. Isibonelo, esimweni sezulu esibandayo, inzwa ingaba nenkinga yokuthola nokuhlaziya idatha ngendlela efanele. Ukunyakaza okungavamile, okufana nomuntu okwenzayo ngesikhathi se-tennis noma isibhakela, isibonelo, kungabangela izinkinga kumitha. Ukuze uthole isilinganiso esifanele, kuyadingeka futhi ukuthi izinzwa zilingane kahle ngangokunokwenzeka ebusweni besikhumba.
Lena yindlela wonke amawashi ezemidlalo akala izinga lokushaya kwenhliziyo asebenza ngayo, ubuchwepheshe obuvela ku-mio.
Iwuphawu olusetshenziswa kakhulu kubasubathi http://www.Polar.com futhi akanikezi lutho olunjalo. Ibhande lesifuba lisanembile kakhulu.
Nikeza ku-mio fuse. Ngingathanda ukubona umuntu ebhukuda ngebhande esifubeni.
Ibhande lesifuba libuye lifanele ukubhukuda. Ngisho ne-Polar H7 isebenzisa i-5kHz transmission ngaphezu kwe-bluetooth, esebenza emanzini. Ngilangazelela ukubona ukuthi ubani ozobhukuda nge-iWatch. Mhlawumbe uBeyoncé noma uKaty Perry. Akekho noyedwa othanda ubulili obuhlukile oseke waba nayo ezandleni zakhe okwamanje.
Ekekho neyodwa. Awavimbeli amanzi.
Impela. Ngine-Polar H7. Inembe ngokuphelele kuwo womabili ama-iP4 kanye ne-Note 3. Ukuqagela okunjalo kanye njalo ngemizuzu eyi-1 akusizi ngalutho. Ngaphezu kwalokho, njengoba kunemisebenzi eminingi, kungcono ukuba newashi kwenye indawo. Isibonelo, uma uphotha ezibambo. Ngakho awukwazi ukwenza ngaphandle kwebhande lesifuba noma kunjalo. Kuyathakazelisa futhi ukuthi ukuze kunwetshwe impilo yethoshi, kufanelekile ukusungula izibani ezimbili nezinye izici esikhundleni sokubeka ibhethri elikhulu lapho.
Iqiniso lokuthi iwashi elilodwa alinikezi akusho lutho, ngine-cardio futhi lapho kufanele ngibheke le webhusayithi ngibhale lokhu kuphela ngoba kubonakala sengathi i-Apple eyasungula.
Lokhu akulona iwashi elilodwa, kodwa umkhiqizi we-Polar nomkhiqizi we-Polar baphakathi kwemikhiqizo yakudala. Lokho kufana nokucela i-Apple ukuthi iqale ukwenza izincwadi zokubhalela ngesikrini sokuthinta, okuyinto efanayo.
Isebenza kanjani i-Mio….

Kumsubathi, ukushaya kwenhliziyo kufanele kulinganiswe ngokunembile ngangokunokwenzeka, futhi ukuphambuka kuka-5 sekuvele kuphelile. Ngokwami, angisoze ngathenga i-Mio.
Imitha ye-Mio ibekwe kabi esandleni sami. Iphezu kwethambo futhi ayinamathele embuzi. Kufanele ihanjiswe kakhulu endololwaneni. Futhi i-polar isebenzisa ukhalo lwesifuba, ngakho-ke inganyakaziswa kalula ibheke endololwaneni ukuze kube nendawo eyanele ye-mio.
Ubhala ekuphawuleni ukuthi unesikhumba esimnyama, futhi mhlawumbe yingakho engalungile, kodwa ngicabanga ukuthi kwakungalungile.
Ngibone ndawana thize kuvidiyo ukuthi iwashi kumele lilinyazwe ngokucophelela esandleni ukuze lingacishi futhi lingalinganisi umbhedo. Ngokwami akungimangazi uPolar (umholi) ukuthi abazange baqale ngalawa mawashi ngaleso sikhathi.
Wazi kanjani ukuthi ayinembile kakhulu? Mhlawumbe esheshayo, kodwa enembe kakhulu kunzima ukusho. Ngizame kokubili iPolar neSuunto...akunankinga. Manje ngineFitbit Charge HR kanye neFitbit Surge futhi lapho ngiyiqhathanisa ne-Polar, ukulinganisa kwakuhamba kancane kwesibili. Kodwa bobabili babonise idatha efanayo.
