Another interesting invention is described in one of the figures ("DSME's New Technology"): Freeze Pirates! - DAPS DSME launched its new pirate alert system 'DSME Anti-Piracy System (DAPS). ... DAPS is a total ship security system for recognizing and eradicating piracy. By using the ship's radar signal, the DAPS is able to analyze image information. This system automatically judges suspected targets based on the analyzed information. If suspected pirate ships approaches [sic], DAPS will warn the target through a high output speaker and sound an alert on the ship. If the pirate comes closer, a sound cannon or water cannon will be used to incapacitate the pirate. -- In many ways, that is more impressive (and scarier).
