  • Publication number: 20150136761
    Abstract: The microwave heating apparatus of the present invention enables microwaves to be propagated onto an object to be heated through a waveguide such that the microwaves propagate to a microwave space reduced by a wavelength controller which is arranged, as a solid-state object, to occupy a predetermined space in the waveguide. Thus, the microwave heating apparatus of the present invention heats the object to be heated which has been placed in the reduced space. The microwave heating apparatus of the present invention utilizes the effects of lengthening the wavelength of the microwaves propagating to the reduced space so as to be longer than the wavelength before entering the reduced space by a predetermined multiple depending on a near-cutoff condition.

  • Patent number: 8741434
    Abstract: Disclosed herein is a transparent conductive polycarbonate film coated with carbon nanotubes, including a transparent conductive layer formed by applying a mixed solution of carbon nanotubes and a binder on one side or both sides of a transparent polycarbonate film, and a touch panel using the transparent conductive polycarbonate film as a lower transparent electrode. The present invention provides a transparent conductive polycarbonate film coated with a mixed solution of carbon nanotubes and a binder, by which a touch panel having high transmissivity can be manufactured by directly forming a transparent conductive layer on a polycarbonate film used as a protective film of a liquid crystal display using carbon nanotubes, without using a polyethylene terephthalate (PET) substrate used for a transparent electrode of a conventional touch panel, by which the production cost of the touch panel can be decreased, and by which a thin touch panel can be manufactured.

  • Patent number: 8374149
    Abstract: Disclosed herein are a method of controlling Hierarchical Mobile IPv6 (HMIPv6) network-based handover and an Access Router (AR) and Mobile Node (MN) therefor. The method include the steps of a first AR, to which a MN is connected, receiving an L3 handover initiation message, including a Media Access Control (MAC) address of the MN and the ID of a target Base Station (BS); the first AR creating a Local Care-of Address (LCoA) based on the MAC address of the MN and the ID of the target BS, and performing Binding Update (BU) on a Mobility Anchor Point (MAP) using the created LCoA; when an L2 handover completion message is received from the target BS of the MN, a second AR creating a second LCoA and transmitting the second LCoA to the MN; and the MN receiving the second LCoA from the second AR and configuring the received second LCoA as its own LCoA.

  • Publication number: 20100054183
    Abstract: Disclosed herein are a sensor network control method for data path establishment and recovery and a sensor network therefor. The sensor network control method includes the steps of (a) the sink node or a first sensor node creating an interest message, including information about a hop count between itself and the sink node, and transmitting the interest message to one or more neighboring nodes; (b) a second sensor node, which has received the interest message, creating a routing table using the hop count information of the interest message and information about the node having transmitted the interest message, (c) the second sensor node determining a data transmission path for data transmission to the sink node using the routing table; and (d) the second sensor node transmitting an interest message, including information about a hop count between itself and the sink node to at least one neighboring node.
