Before revision: Unlike previous “on/off” techniques, Torres defined a method for controlling any mechanical or electrical device with different states of operation, selecting different positions for the steering engine and different velocities for the propelling engine independently, and acting over other mechanisms such a light, or a flag, at the same time,A.
