Circuit triggers magnets which darkens exhaust (of an engine-driven aircraft) for a shorter or a longer time, thereby yielding Morse code.
- "It will be obvious from the foregoing description that any predetermined signal may be transmitted automatically by darkening the exhaust from the motor of an aerial machines for long or short periods corresponding to the dashes and dots of a telegraphic code and that the signals so produced in the wake of the aerial machine will be outlined against the sky and will be readable by means of a field glass at a distance."
For night communication, the vessel can be equipped with an apparatus containing "strontium or other pyrotechnic material" to produce "flashes of colored light".
