1. Pozrel som si clanok o pracovnom rozsahu teplot mobilnych telefonov. Podla tabulky na druhej strane clanku v [1] su rozsahy teplot velmi male (tabulka je vo Fraenheitoch) a lisia sa medzi mobilmi.
Najodolnejsi je specializovany Samsung Xcover (-20 C-50 C). Apple iPhone maju „kalifornsky“ teplotny rozsah 0 C-35 C. Nokie su lepsie : -10 C-55 C a SAMSUNGY su uplne vyborne : -20 C-50 C.
Clanok [2] popisuje priserne teplotne podmienky v zatvorenom aute v lete a dopad na dieta – teplota sa moze ustalit az na 60 C za 60 minut. Nasa apliakcia Car-E-baby bude multisenzorova a procesor v mobile vytazeny. Mobil moze prestat fungovat v dosledku vysokej teploty v aute. Musi vsak ucinne zafiungovat pocas prvych 5-15 minutach ked teplota v aute dosiahne 50 C.
Potom je asi aj tak uz neskoro ( 🙁 ).
Vid vysledky vyhladavania [3] a statistiky umrti deti v aute v USA [4].

2. Cez sviatky sa budem venovat analyze poziadaviek na apku pre Android a zatial technologiu tagov dame bokom. Apka by integrovala viacero senzorov sustredenych v smartfone s cielom detegovat touto fuziou senzorov pritomnost ziveho tvoreka na palube odstaveneho auta. S Tvojim dovolenim by som tuto myslienku presiel so synmi – su sikovni a dokazu byt velmi kriticki ale zaroven konsktruktivni.
Spracovanie obrazu by som robil s kniznicou OpenCV pre Android [1] . Asi sa nevyhneme integracii kodu C++ do aplky – kvoli rychlosti. Zvuk a vibracie sa daju analyzovat na Androide takisto [3] . Mali by to byt komercne pouzitelne kniznice.

3. Technologia BLE tagov pre projekt Car-E-Baby urobil som kratku resers sledovacich zariadeni pre deti (vid dole).Ide o kombinaciu GPS+Bluetooth nositelnych zariadeni (hodinky).Projekt by som nazval CAR-e-BABY alebo CAR-e-HONEY.Pre nas ucel (zabranit ponechaniu dietata v aute) postacuje kombinacia viacerych „CAR-e-TAG-ov“ (elektronickych zariadeni s Bluetooth) a mobilnej apliakcie beziacej na lubovolnom pocte mobilov (vyuzivajucich GPS, Bluetooth a datovy prenos). Princip ochrany dietata by bol taky, ze dieta bude nosit CARE-e-TAG, to iste zariadenie bude doma, v skolke a hlavne v aute. Elektronika kazdeho CAR-e-TAG-u bude vzdy ta ista len forma bude ina a bude respektovat ucel v systeme. Kazdy CAR-e-TAG bude niekomu/niecomu patrit. Rodic si nakonfiguruje aplikaciu a ta sa postara o to aby dieta nezostalo v aute same. System upozorni na zabudnuty CAR-e-TAG. Aj samotny mobil ci tablet moze byt CAR-e-TAG – tym sa system stava flexibilny (vodic si sparuje svoj mobil s CAR-e-TAG-om dietata).
Cena za CAR-e-TAG bu by mohla byt pod 5 USD. Jeho cenu urcuje modul Bluetooth, moderne malu nizku spotrebu v neaktivnom stave, je tam sifrovana komunikacia a slusny dosah (radovo metre a viac).
Zakaznikovi sa ponukne aj sledovacia sluzba „CAR-e-BABY Services“ Ta spracuvajuca GPS suradnice cez datove prenosy a alarmujuca rodicov v pripad nejasnosti. Zapozicia prvky systemu, nakonfiguruje system podla potreby, vymeni tagy ked im dojde baterka. System sa vyuzit aj pri striedavej starostlivosti rozvedenych rodicov, pestunskej a aupair starostlivosti ci starorodicovskej starostlivosti. Umozni sledovat starych ludi. Takisto by sa dal pouzit pri domacich milacikoch. Neviem preco toto uz niekto nerobi 🙂

4. CAR-e-TAGy pripajam este doplnujuce informacie z reserse à pre CAR-e-TAGy existuju vhodne moduly BLE (Bluetooth) a daju sa kupit ako OEM vyrobky – vid napriklad bod 6-1. Netreba teda vyvijat ziaden hardver.
Z pohladu technickej realizovatelnosti (hardveru a softveru) sa da sa teda hned pristupit k realizacii zivotneho cyklu funkcneho vzoru systemu (t.j. poziadavky, analyza, navrh, realizacia a testovanie ). Preferujem kupu OEM BLE modulov na baze znameho BLE cipu t.j. spominany 6.1. ma Texas Instruments CC2541.
Vstupne naklady pre vyvoj funkcneho vzoru a jeho pripravu by mohli byt pomerne nizke – islo by hlavne o vyvoj
mobilnej aplikacie (myslim tym cely jej zivotny cyklus) na ANDROID-e s niekolkymi mobilmi, tabletmi a OEM BLE modulmi a vyvojovym kitom k nim (material do 1000 Euro ak nepocitam notebooky ci PC). V pripade prototypu by naklady boli vyssie s ohladom na potrebu spolupracovat s grafikom ci dizajnerom. Tiez by narastol objem potrebneho softveru.
