  • Patent number: 10410608
    Abstract: An electronic device and a method for displaying an image transmitted by a robot and remotely controlling a movement of the robot are provided. The electronic device includes a communicator, an inputter, a display, and a controller. The communicator receives, from the robot, an image photographed by the robot and time information. The inputter receives a command to control the robot. The display displays a screen corresponding to the image. The controller calculates a time delay between the electronic device and the robot based on the time information, control the display to display a graphical object to be overlaid on the screen, and control the communicator to transmit the command to the robot. The graphical object represents a field of view of the robot at a current time. The field of view of the robot at the current time may be estimated based on the time delay information.

  • Patent number: 8198038
    Abstract: The present invention relates to a plasma biomarker for diagnosing hepatocellular carcinoma (HCC), in particular to the discovery of a protein in plasma using 2-D fluorescence differential gel electrophoresis (2-D DIGE), immunoprecipitation and Nano-liquid chromatography mass spectrometry (Nano-LC-MS/MS) system that was unknown on the basis of conventional techniques. By demonstrating the presence of liver carboxylesterase 1 (hCE1) in human plasma and confirming that its secretion level is higher in patients with HCC than in healthy volunteers, this invention may be used as a screening method to diagnose HCC at an early stage.

  • Publication number: 20050232286
    Abstract: A route optimization system and method for packet transmission between particular nodes in a mobile network including a plurality of nodes. If a predetermined mobile router (MR) receives a packet transmitted from a predetermined mobile node (MN) connected to its subnet, the MR transmits the packet to its associated home agent (HA) through a previously established default tunnel. Upon receiving the packet, the HA adds registration information of the MR to the packet and transmits the registration information-added packet to a correspondent router (CR) of a correspondent node (CN) for which the packet is destined. The CR acquires registration information of the MR from the received packet, and forms a route-optimized tunnel for packet transmission to the MR according to the acquired information.

  • Publication number: 20050232146
    Abstract: A system and method in a mobile network in which a first router manages a first subnet including at least one second router and the at least one second router manages a second subnet including at least one mobile node. In a method for recovering a routing path between the first router and the at least one mobile node, the first router receives, from the at least one second router, information of neighboring routers included in the first subnet, and stores the received neighboring router information. An occurrence of routing path failure is recognized when a periodic report message is not received from the at least one second router within a preset time. An alternative router is selected from among the neighboring routers when the failure occurrence is recognized, and a routing path recovery request is sent to the alternative router. Data is routed to the at least one mobile node through the alternative router when the alternative router positively responds to the routing path recovery request.

  • Publication number: 20050058100
    Abstract: A method for optimizing a tunnel between a second mobile router and a home agent of the second mobile router in a mobile network having a nested structure in which a first mobile router manages a subnetwork including at least the second mobile router. The second mobile router manages a subnetwork including at least one node. The second mobile router receives nested path information from the first mobile router. The second mobile router transmits the nested path information to the home agent of the second mobile router via the first mobile router. The home agent of the second mobile router stores the nested path information received from the second mobile router thereby performing tunneling with the second mobile router.
