  • Publication number: 20190158865
    Abstract: The present invention relates to a video signal decoding method for adding an intra prediction mode as a sub-macroblock type to prediction of a macroblock in coding a video signal. Some implementations may include obtaining a macroblock type, when a macroblock includes the intra prediction coded sub-macroblock and the inter prediction coded sub-macroblock based on the macroblock type, obtaining prediction mode flag information indicating whether the sub-macroblock is the intra prediction coded or the inter prediction coded, and obtaining a prediction value of the sub-macroblock. Accordingly, implementations disclosed herein may raise coding efficiency of video signal by adding an intra prediction mode as a sub-macroblock type in predicting a macroblock.

  • Publication number: 20190137175
    Abstract: Disclosed is an adiabatic collector for recycling gas, a liquefier for recycling gas, and a recovery apparatus for recycling gas using the same. More specifically, gas to be recycled is collected in an adiabatic manner, cooled to a temperature lower than the dew point thereof, and stored in the liquid state through a phase change, thereby saving energy required for re-cooling the gas. Particularly, the present invention relates to an adiabatic collector for recycling gas, a liquefier for recycling gas, and a recovery apparatus for recycling gas using the same, in which recycling gas is compressed through a natural inducement method using a difference in temperature and pressure while being collected and liquefied, thereby reducing noise, vibration, and size of the collector.

  • Patent number: 9947285
    Abstract: A voltage converter includes a conversion unit, a self driver and an output unit. The conversion unit includes at least one inductor and provides a boosting power based on an input voltage and a first driving signal. The self driver includes at least one inductor that forms a magnetic coupling with the at least one inductor of the conversion unit. The self driver generates a second driving signal that is synchronized with the first driving signal through the magnetic coupling. The output unit generates an output voltage based on the boosting power and the second driving signal. Switching loss and conduction loss may be reduced by replacing an output diode with an output transistor and voltage spike and electromagnetic interference may be reduced through zero voltage switching. The driving signal of the output transistor may be controlled efficiently by adjusting the inductance of the driving inductor.
