Uchungechunge lwe-Apple Watch 3: I-Teardown yembula ibhethri elikhulu | Ama-Road Safety Reflectors

Isaziso: Kubonakala sengathi i-Javascript yakho ikhutshaziwe kusiphequluli sakho. Ukuze uthumele amazwana kulokhu okuthunyelwe, sicela ubhale le khodi kanye nokuphawula kwakho: 598a1ad048b047886e89d07b769eb4bd

Umfana wayehamba eceleni komgwaqo eya eningizimu eduze kwemayela 20 lapho ewela umugqa wenkungu eya emgwaqweni omkhulu. Imoto ephuzi ka-2009 Chevrolet Traverse, nayo eyayiya eningizimu, yabe isimshaya ibhayisikili lomfana. Umshayeli, owesifazane oneminyaka engu-29 ubudala waseMattawa, akakhulunywanga ngaye.

Isifinyezo: Ithuluzi lokwenza isihlalo elisetshenziswa ethuluzini lokudonsa eliqukethe ilungu lokushayela kanye nezinto zenja ezibekwe futhi zithuthelwe ngaphakathi kwendlu yangaphandle yethuluzi lokudonsa liye ladalulwa. Izinto zenja ziqondana emihumeni egobile endlwaneni yangaphandle yethuluzi lokudonsa endaweni yokuqala futhi ziphuma emihumeni endaweni yesibili. Ilungu lokushayela lihamba ngendlela ephambene futhi lenza izinto zenja zisuke endaweni yokuqala ziye endaweni yesibili futhi zakhe isihlalo ethuluzini lokudonsa. Isihlalo esakhiwe sinobubanzi obungaphakathi obuncane kunento yokukhawulela ukuvumela into yokukhawulela ukuthi ihlale.

Lo mhlangano ulandela izingozi ezimbili ezibulale abantu emigwaqweni emikhulu i-Techiman-Kintampo kanye ne-Winneba-Cape Coast ngesonto eledlule ezabulala abantu abangaphezu kuka-80 kwalimala abanye abaningana.

Isifinyezo: Isilawuli esihlanganisa i-voltage synthesizer ye-switching regulator sihlanganisa i-synthesizer input ezoxhunywa ekufakweni kwe-regulator. Ama-transistors okuqala nawesibili aphindaphindwayo axhunywe kwi-node yokuqala. I-resistor ixhumanisa phakathi kwe-node yokuqala ne-node yesibili, kanti i-capacitor ixhumanisa phakathi kwe-node yesibili nomhlabathi. Isigaba se-transconductance siqhathanisa i-voltage ethathwe ku-capacitor ne-voltage yokuphuma ye-regulator futhi ikhiqiza isignali yokuphuma ephendula ekuqhathanisweni. I-switch yokuqala ixhumanisa phakathi kokufakwa kokuqala nokwesibili kwesigaba se-transconductance. I-switch yokuqala ivuliwe ngesikhathi somjikelezo ngamunye wokusebenza kwe-voltage synthesizer ukuze kusethwe kabusha i-voltage ye-capacitor ku-voltage yokuphuma ye-regulator.

Isifinyezo: Ukwakheka kweprosesa okuhlukanisa idatha ekwi-chip ukuze kugcinwe kahle okufakiwe kokuhumusha kanye nedatha okunciphisa ukungqubuzana phakathi kokuhumusha kwekheli elibonakalayo nelingokoqobo kanye nokufinyelela kwedatha. Ukwakhiwa kufaka phakathi ama-core eprosesa afaka i-buffer yokuhumusha yezinga lokuqala (TLB) kanye ne-TLB yezinga lesibili etholakala ngaphakathi kwe-core ngayinye yeprosesa noma eyabelwe kuwo wonke ama-core eprosesa. Ngaphezu kwalokho, ukwakheka kufaka phakathi i-cache yedatha yezinga lesibili (isb., etholakala ngaphakathi kwe-core ngayinye yeprosesa noma eyabelwe kuwo wonke ama-core eprosesa) ehlukaniswe ukuze kugcinwe kokubili idatha kanye nokufakiwe kokuhumusha. Ngaphezu kwalokho, ukwakheka kufaka phakathi i-cache yedatha yezinga lesithathu exhunywe kuma-core eprosesa, lapho i-cache yedatha yezinga lesithathu ihlukaniswa khona ukuze kugcinwe kokubili idatha kanye nokufakiwe kokuhumusha. I-cache yedatha yezinga lesithathu yabelwe kuwo wonke ama-core eprosesa. Ukwakhiwa kweprosesa kungafaka futhi i-profiler yebanga le-stack yedatha kanye ne-profiler yebanga le-stack yokuhumusha.

“Kwakuyinqubo yokunamathisela nokuyifaka ezintweni ezithile esasinomuzwa wokuthi zingadala umbono esasiwufuna,” kusho uCollins.

Iqembu Lokukhulisa Izingane: Joyina abanye abazali abafuna izindlela zemvelo zokuthuthukisa impilo yabo kanye nezingane zabo. Leli yiqembu le-Pathways Connect ngakho sizoxoxa ngezihloko ezisohlwini lwemagazini i-Pathways Connect olunikezwa yi-Int's Chiropractic Ped Association. Joyina nathi ukuze ufunde kabanzi futhi uhlangane nabanye abazali abanomqondo ofanayo. Imihlangano iba kanye ngenyanga ngoMgqibelo kusukela ngo-11 ekuseni kuya emini. Isikhala sincane, ngakho-ke sicela uphendule ku-mbodychiropractic@gmail.com noma ngokushayela ku-267-462-4911.www.mbodychiropractic.com.

10 Meyi 2018 - I-HEIDENHAIN yethule i-ND 5023 digital readout (DRO) ukuze isetshenziswe ngamathuluzi omshini asetshenziswa ngesandla. Le DRO ithatha indawo yamamodeli e-HEIDENHAIN asezingeni lokuqala le-ND 522/523 futhi iwahlanganisela kumkhiqizo owodwa onama-axis amathathu. I-DRO iza ifakwe isibonisi sombala se-TFT esithuthukisa ukufundeka kolwazi oluboniswa kumamodeli amadala, kanye nezinye izinguquko zomklamo kanye nemisebenzi ethuthukisiwe. Umhlahlandlela wokufaka usufakiwe ukusiza ekwenzeni ukucushwa okuyisisekelo. Uma uvula iyunithi okokuqala, umsebenzisi angakhetha lesi sici sokusekela bese eqondiswa ngezilungiselelo ezidingekayo isinyathelo ngesinyathelo. Izici eziningi zethulwa ku-ND 5023 kufaka phakathi isici sokusondeza esenzelwe ukuthuthukisa ukufundeka kwenani lesikhundla. Uma selivuliwe, inani lokubonisa le-axis ehanjiswayo njengamanje liyakhuliswa. Ngezinombolo ezincane (okungukuthi, izinombolo eziseduze no-zero), ukuphakama kwezinhlamvu kungakhushulwa kusuka ku-17 mm (ukuphakama okujwayelekile) kuya ku-25 mm. Umqhubi ubona ngokushesha ukuthi iyiphi i-axis ehambayo njengamanje futhi angafunda nenani lezinombolo ekude kakhulu. Lapho i-axis iyeka ukuhamba, isibonisi sibuyela kusayizi waso ojwayelekile. Isibonisi siphinde silungiselelwe ukusebenza ngesandla sokudla noma kwesobunxele. I-ND 5023 DRO nayo inendlu ye-aluminium eboshwe nge-powder, futhi, njengeyandulelayo, isebenzisa ikhibhodi ye-membrane. Njengangaphambili, ama-encoder ane-interface ye-TTL (ehlukile kanye ne-single-end) angaxhunywa ngesixhumi se-D-sub esingu-9-pin. I-interface yedatha ku-ND 5023 ishintshwe yaba yi-USB Type C enenzuzo yokuvumela i-digital readout ukuthi ithathe imisebenzi yenkosi kanye nenceku. Ngaphezu kwalokho, inketho yokufaka yonke indawo isetshenzisiwe kule DRO entsha. Ine-interface ye-VESA-MIS 100 ngemuva evumela ukusetshenziswa kwezibambi ezijwayelekile zokufaka. Izixazululo ze-HEIDENHAIN ziyatholakala.

Ibhulokhi ye-Volta NVENC ayimbi, futhi cishe ingabhekana nanoma yimuphi umthwalo womsebenzi umdlali wesabelomali angase awuphonse kuyo. Kodwa-ke, kuseyisinyathelo esibuyela emuva futhi kunikeza esinye isizathu sokubheka ama-GPU aphezulu njenge-GTX 1660 nangaphezulu.
