Abstract:
A device for measuring a penetration rate of outdoor air including humidity or oxygen of a material, and a reaction material cartridge for measuring an outdoor air penetration rate. The device includes a reacting part including a reaction material which reacts upon contact with outdoor air passing through a substrate; a cartridge body which accommodates the reaction part, and which is detachable from a measuring unit for measuring a change corresponding to the contact of the reaction material with the outdoor air; and a shielding means which shields the cartridge body, and which is separated from the cartridge body for contact between the reaction material and the outdoor air.
Abstract:
The present invention relates to a method for selecting an appropriate mode when performing a new broadcast, such as a 3D stereo broadcast, a UHDTV broadcast, and a multi-view broadcast, among others, while maintaining compatibility with existing broadcasting channels in an MPEG-2-TS format for transmitting and receiving digital TV, and to a method for recognizing a descriptor. To this end, the present invention suggests providing the descriptor which is related to synthesizing left and right images using the type of stream, existence of the descriptor, and a frame-compatible mode flag.
Abstract:
A method for separating audio sources and an audio system using the same are provided. The method introduces the concept of a residual signal to separate a mixed audio signal into audio sources, and separates an audio signal corresponding to at least two of the audio sources as a residual signal and processes the audio signal separately. Therefore, audio separation performance can be improved. In addition, the method re-separates a separated residual signal and adds the separated residual signals to corresponding audio sources. Therefore, audio sources can be separated more safely.

The concentrated photovoltaic module according to the present invention includes: a concentrated lens array module having at least one condenser lens; a solar cell positioned at the lower end of the condenser lens; a substrate positioned at the lower end of the solar cell and supplied with the heat generated in the solar cell; a flat plate-type heat pipe positioned at the lower end of the substrate; a flat plate-type heat sink positioned at the lower end of the flat plate-type heat pipe; and a condenser lens array structure fixing the condenser lens array module to the substrate.
Abstract:
A method and apparatus for generating/converting a digital hologram is provided. The method for generating the digital hologram includes: clustering points of a 3D object to a plurality of clusters according to a distance to a screen; generating diffraction patterns in a unit of a cluster; and generating a fringe pattern by overlapping the diffraction patterns with one another. Accordingly, calculation complexity can be reduced and thus it is possible to generate a digital hologram at high speed. Since a range/size of a cluster which has a trade-off relationship with an image quality of a digital hologram is adjustable, it is possible to generate a customized flexible digital hologram.

The present health care method includes receiving human body information, calculating a human body index based on the received human body information, generating a health care program based on the calculated human body index and providing the generated health care program to a user. By this system and method, it becomes possible to measure and monitor stress/fatigue/health indexes of a user in living environments, thereby effectively supporting well-being life of the user.
Abstract:
The present invention relates to an energy conversion substrate using a liquid and, more specifically, to an energy conversion substrate using a liquid capable of converting mechanical energy into electric energy through a flow of a liquid on a substrate having an energy conversion layer. Thus, the present invention enables easy manufacture and easy liquid circulation to be obtained by implementing an energy conversion device using a liquid through one substrate instead of a pair of opposing substrates and can implement the energy conversion device without a lubricating layer.
