Abstract: An orientation fault detection system is configured to detect improper installation of the dynamic active control system (DACS) controller/software module by receiving data output from a plurality of sensors to determine whether an orientation fault is detected corresponding to an improper installation of the controller/software module. Such determination is made based upon sensor data when corresponding environmental and operational conditions are met, so the orientation fault detection system is further configured to determine whether the requisite conditions are met for orientation fault detection based upon the sensor data. If an orientation fault is detected, the orientation fault detection system initiates a safe state protocol that renders the vessel safe to operate.

Abstract: A data processing system implemented method, a data processing system, and an article of manufacture determine discrepancies between a first database management system and a second database management system. The first database management system populates a first database and the second database management system populates a second database. The data processing system implemented method includes receiving a first query response, the received first query response generated by the first database management system querying the first database, receiving a second query response, the received second query response generated by the second database management system querying the second database, detecting discrepancies between the received first query response and the received second query response, and providing an indicator, the provided indicator indicating the detected discrepancies.
