20090046083 | Digital-to-Analog Converter for display device - A digital-to-analog converter (DAC) for a display device is provided. The DAC includes an amplifier and a current decoder. The amplifier receives a gradation voltage with respect to upper bits in data of k bits through a non-inverting input terminal, and varies the input gradation voltage according to a voltage applied to an inverting input terminal. The current decoder allows a predetermined constant current to flow therethrough according to input data of lower bits, which do not include the upper bits, to thereby vary the voltage applied to the inverting input terminal. The current decoder further adjusts the gradation voltage outputted by the amplifier according to the varied voltage. | 02-19-2009 |

20120013483 | Water Supply Maintenance System - A GIS-based computerized system is provided for maintaining a water supply system having a pipe network and a plurality of measuring sensors. The maintenance system includes a transmitter that receives information from the measuring sensors, and transmits the information, a collector that collects the information transmitted by the transmitter, an information analyzer that analyzes the collected information and decides prescribed status variables for the maintenance system, a storage that stores information provided by the collector and the information analyzer, an alarm device that generates an alarm when the information analyzer decides a leak expectation, a sensor error or an abnormal operation, a pipe network analyzer that analyzes the pipe network base on the collected information. The pipe network analyzer analyzes the information stored by the storage based on a pipe network scheme that is constructed with space data of the water supply system. | 01-19-2012 |
20120150783 | Disaster Analysis and Decision System - A disaster analysis and decision system comprises a geographic area module that comprises geographic data for a given geographic area; an artificial facilities module that comprises artificial facilities data positioned in the geographic area; a disaster control facilities module that comprises disaster control facilities data for the geographic area; an environmental variable module that receives and stores environmental variables that affects the geographic area; an analysis module that analyzes how the environmental variables affect the geographic area, the artificial facilities within the geographic area and the disaster control facilities for the geographic area, and decides how to control the disaster control facilities; a report module that provides reports for the analysis; and a database that stores data from other modules. | 06-14-2012 |
