An inductive heating device is structured such that a coil base and ferrites placed under a heating coil in the vertical direction are flushed with each other at their lower surfaces and are directly placed on a heat dissipation plate. The container has an outlet port located at a downstream end of the container and container threads formed on an upstream end of the container. Each member has a plurality of light sources connected to it. Real-time downhole flow measurements are correlated to provide a production flow rate profile. Upon an occurrence of a bonus game triggering event, the gaming system randomly selects one of the maintained bonus game attributes. The method may also include filtering out signals received via LOS paths with performance below a predetermined threshold value.
