초록

A main computer which furnishes main engine control signals to initiate a predetermined operation of an internal combustion engine, outputs a monitoring signal whose state changes between a high and a low levels at predetermined intervals. The monitoring signal is watched by a main computer monitor, which maintains its output at a high level during repetition of the change of state in the monitoring signal and, in absence of the change of state in the monitoring signal, changes the state of its output between the high and a low levels at intervals longer...
