Inyubako zishimishije zubatswe uyumunsi ningufu zikoresha ingufu, zangiza ibidukikije nicyatsi kibisi.Gukwirakwiza Ibirahuri (bikunze kwitwa IGU cyangwa IG unit) hamwe na E-E bitwikiriye bimaze kuba amahitamo yambere yubwubatsi bugezweho.Ntabwo bikiri ukurinda umuyaga gusa, ariko cyane cyane guhuza ibikorwa byinshi byo kubika ubushyuhe, kuzigama ingufu, ubuhanzi, gutuza n'umutekano.Itanga ahantu heza ho gutura abantu bashobora kwishimira ibihe bine, gukoresha ingufu, ibidukikije-urugwiro no kumurika.
Jinjing itanga ibishushanyo byinshi byo kubika ibirahuri, amahitamo menshi kuri IGU.Ibice bikingira kandi bifite amahirwe menshi yuburyo bwiza bwo kuzamura isura nigikorwa cyinyubako yawe, harimo silik-ecran & digitale ya digitale hamwe namabara akungahaye, uduce hamwe nu mwobo niba bikenewe, kuzuza argon, kugoramye kimwe no gushushanya IGU.
