COMPACT FAIL SAFE INTERFACE AND VOTING MODULE COMPRISING IT

摘要

The interface is formed by an astable multivibrator ring type oscillator comprising an odd number of inverting components. The power supply inputs of the inverting components constitute the functional inputs of the interface. The oscillator output signal is a continuous signal as soon as one of the inputs is no longer supplied correctly and the interface has the property of being strongly fail safe with respect to all the failures which may occur within it. The interface can be used as the base component of a voting module.
