Apparatus and instruments, namely, electronic control devices for conducting, switching, transforming, accumulating, regulating or controlling electric current; electronic systems comprised of electronic sound controllers and dampeners for noise reduction through sound signals emitted out-of-phase in noisy interior spaces that cancel sound beams; electronic systems comprised of vibration dampeners for reducing vibration through vibrations triggered out-of-phase in the field of elastic mounting of motors
