  • Loose part monitoring method and system
    Patent number: 8446287
    Abstract: A loose part monitoring method and system for preventing the generation of a false alarm as much as possible, including analyzing a group of detection signals that have been output from a plurality of sensors placed on a wall defining a fluid flow path, wherein the group of detection signals are analyzed for a rising gradient that is related to change in intensity of impulsive sound, a damping time that is related to change of intensity of the impulsive sound, and a frequency spectrum that is related to pitch of the impulsive sound in order to determine whether the group of detection signals are false or true.
