I-XDB403 yochungechunge lwezidlulisi zengcindezi ephezulu yamazinga okushisa asebenzisa umgogodla womfutho we-silicon ohlukanisiwe ongenisiwe, igobolondo elifakazela ukuqhuma kwezimboni elinosinki wokushisa neshubhu le-buffer, ithebula lesibonisi le-LED, ukuzinza okuphezulu kanye nenzwa yokucindezela kwe-piezoresistive enokwethenjelwa okuphezulu kanye nesekethe eqondene ne-transmitter esebenza kahle kakhulu. Ngemuva kokuhlolwa kwekhompyutha okuzenzakalelayo, isinxephezelo sezinga lokushisa, isignali ye-millivolt yenzwa iguqulelwa ku-voltage ejwayelekile kanye nokukhishwa kwesignali yamanje, engaxhunywa ngokuqondile kukhompyutha, ithuluzi lokulawula, ithuluzi lokubonisa njll., futhi ingakwazi ukudlulisa isignali yebanga elide .
