  • Publication number: 20160169208
    Abstract: In an air-cushioned small hydraulic power generating device, when a stator in a generator linked by means of an upper rotational shaft to a first vertical-shaft windmill rotates in a first direction, a rotor in the generator linked by means of a lower rotational shaft to a second vertical-shaft windmill and an air-cushioned water wheel rotate in a second direction opposite to the first direction, thereby increasing the rotational force and thus enhancing the power generation efficiency. The generator can be easily installed in valleys, watercourses, rivers, irrigation water channels, or seawater channels without having geographic limitation. Furthermore, since an air-cushioned water wheel is used to support the weight of the generator and rotational shafts, the generator can be easily installed to float on the surface of water. Therefore, breakdown and maintenance cost of the generator can be minimized.

  • Publication number: 20070136203
    Abstract: Disclosed are a subscriber management system and a method thereof using OOB (Out Of Band) channel in the DMB (Digital Multimedia Broadcasting). The system of the invention transmits a message for the alteration of the subscriber information to terminal through the OOB, and receives the result of the transmitting of message, that the result comprises a success of the transmitting/alteration, a failure of the alteration, and an error of the transmitting. Therefore, the system is able to apply the alteration of subscriber information to the terminal as soon as the subscriber information is altered.
