20130226450 | APPARATUS AND METHOD FOR SUPPORTING SAFE NAVIGATION OF SHIPS - Disclosed is an apparatus and method for supporting the safe navigation of ships based on mobile terminals which can prevent accidents at sea including marine collisions between small ships sailing near the coastline. The method for supporting the safe navigation of a ship in conjunction with a mobile terminal carried by a crew member of a ship includes collecting information about the navigation of the ship by a safe ship navigation supporting apparatus positioned in the ship, collecting information about surrounding ship through group communication with a server corresponding to the surrounding ship, converting a chart transmitted from a ground server into a format compatible with the mobile terminal, and applying safe navigation information created on the basis of the information about the navigation and the information about the ship to the converted chart, and providing the crew member with the safe navigation information through the mobile terminal. | 08-29-2013 |
20130103379 | APPARATUS AND METHOD FOR VERIFYING INTEROPERABILITY BETWEEN APPLICATION SOFTWARE AND AUTOSAR SERVICE - The present invention relates to an apparatus and method for verifying interoperability between application software and AUTOSAR services. The apparatus includes an AUTOSAR interoperability configuration unit configured to configure an interoperability relationship between AUTOSAR service components defined to provide the AUTOSAR services and the components of the application software for an Electronic Control Unit (ECU) performing functions requested by the application software and a simulation unit configured to perform simulations in order to verify whether the interoperated AUTOSAR service components and the components of the application software are normally driven or not based on scheduled task timing. | 04-25-2013 |
20130099914 | APPARATUS AND METHOD FOR CONTROLLING SPEEDOMETER FOR VEHICLE - The apparatus includes an information collection unit configured to collect map information, information about the position of a vehicle, and base station information, a speed limit calculation unit configured to calculate a legal speed limit of a road on which the vehicle is driving, based on the map information, the information about the position, and the base station information, a speedometer display mode storage unit configured to store a number of differently set speedometer display modes for respective legal speed limits of the road, a speedometer display mode extraction unit configured to extract a speedometer display mode corresponding to the legal speed limit of the road among the number of differently set speedometer display modes depending upon the legal speed limit of the road, and a display unit configured to automatically change a previously displayed speedometer display modes to the extracted speedometer display mode. | 04-25-2013 |
20110064422 | POLARIZATION SPLITTER, OPTICAL HYBRID AND OPTICAL RECEIVER INCLUDING THE SAME - Provided is an optical receiver used for an optical communication system, more particularly, a polarization split-phase shift demodulation coherent optical receiver. An optical hybrid includes a first optical splitter, a phase shift waveguide, a second optical splitter, and an optical coupler. The first optical splitter splits a first input optical signal to output first output optical signals. The phase shift waveguide receives the first output optical signals and controls and outputs the first output optical signals such that the first output optical signals have different phases. The second optical splitter splits a second input optical signal to output a plurality of second output optical signals. The optical coupler couples the first output optical signals one-to-one with the second output optical signals, respectively. | 03-17-2011 |
20090102730 | APPARATUS AND METHOD FOR PREDICTING WAVE PROPAGATION CHARACTERISTIC OF MULTIPLE ANTENNA SYSTEM - There is an apparatus for predicting wave propagation characteristic of a multiple antenna system, including: a transmission position calculator for calculating transmission positions of multiple transmitting antennas; a wave propagation path searcher for searching for a wave propagation path for each of a plurality of image antennas generated for each of said multiple transmitting antennas; a reflection electric field calculator for calculating a partial reflection electric field on the searched propagation path; and a received power calculator for calculating a received power based on the calculated partial reflection electric field. | 04-23-2009 |
