Abstract: Provided are an interactive toy whose contents are updated daily, and a method of operating the interactive toy, and more particularly, to an interactive toy in which a wired or wireless communication device and a memory are installed and various contents are downloaded via a web server so as to extract conversation contents from the various contents according to date and other interactive toys and output the extracted conversation contents, and thus allow a user of the interactive toy to engage in conversations with the other users without using an additional conversation contents determining unit, and a method of operating the interactive toy.

Abstract: A system for tracking location of person having signal transmitter includes at least one receiver for receiving unique ID signal transmitted by signal transmitter that transmits ID signal uniquely determined for respective mobile signal transmitter at at least one predetermined period. The receiver receives unique ID signal near circumference of the person having signal transmitter spaced apart from the receiver by given distance, and stores the received unique ID signal in ID store unit. The receiver, when search request for specific ID is received from external server, searches for the requested ID in ID store unit and transmits transmission information including ID corresponding to requested ID to external server. The person, such as abducted person, has only small signal transmitter, and thus the current location of the abducted person and path along which the abducted person moved can be tracked using the signal continually transmitted by the signal transmitter.
