    • An air conditioner and a reverse-phase detection method thereof are provided. According to the air conditioner and the reverse-phase detection method thereof, it is possible to perform reverse-phase detection in real time by subtracting the voltage of one of two phases arbitrarily selected from the phases of an input three-phase alternating voltage from the voltage of the other phase and determining whether the input three-phase alternating voltage is reversed based on sign information of a voltage obtained by the subtraction. Thus, it is possible to prevent an air conditioner from malfunctioning due to a reversed input three-phase alternating voltage and to facilitate the management of an air conditioner.

    • The present invention relates to a system and method for tracking the position of a moving object. A system for tracking the position of a moving object includes: WSNs composed of a plurality of sensor nodes, each generating connection release information representing that the connection between the corresponding WSN and a moving object having a moving node serving as a sensor node attached thereto has released if having perceived the departure of the moving object; base stations managing the plurality of WSNs and collecting position information on the plurality of sensor nodes; a node information database storing the position information on the plurality of sensor nodes collected by the plurality of base stations; middleware checking the current position information on the moving object stored in the node information database if receiving the connection release information through any of the plurality of base stations, and deleting the current position information on the moving object stored in the node information database if the checked current position of the moving object is in a WSN having perceived the departure of the moving object; and a moving-object tracking application provided with the position information on the moving object by the middleware to track the position of the moving object. According to the present invention, it is possible to efficiently process information of a WSN managed by each base station in middleware managing a plurality of base stations, thereby improving the accuracy in tracking the position of a moving object.
