Abstract:
A method of measuring methanol vapor concentration on a real-time basis and a methanol vapor concentration measuring apparatus used in fuel cells. The method of measuring methanol vapor concentration involves using an absorption spectrometry technique, that is, after measuring intensities I0 and I1 of light of a laser before and after passing through a space filled with methanol vapor and into which light is irradiated, the methanol vapor concentration is calculated by substituting the intensities I0 and I1 into an equation defined as I1/I0=exp (K·L·C), where K represents the absorption coefficient, L represents the length of the space through which the laser passes, and C represents the methanol vapor concentration.
Abstract:
A driving circuit of a liquid crystal display includes: a timing controller to output a gate control signal and a data control signal to control driving of a gate driving unit and a data driving unit and to output digital video data; a pair of gate driving units to be alternately driven by using at least one frame as a period to supply gate signals to gate lines of a liquid crystal panel in-response to the gate control signal; and a data driving unit to supply pixel signals to data lines of the liquid crystal panel in response to the data control signal. Degradation of characteristics of transistors constituting each gate driver can be prevented.

Abstract:
System and method provide an on-line high-performance diagnosis service for cardiovascular disorders. A client requests a high-performance diagnosis by transmitting real electrocardiographic treatment data and magnetocardiographic treatment data of a human body being a treatment object and virtual heart simulation parameters to a medical service server. The medical service server, in response to the diagnosis request, analyzes the real electrocardiographic treatment data to generate an electrocardiographic analysis result, and performs a virtual heart simulation using the simulation parameters to generate a pseudo electrocardiogram and magnetocardiogram. Further, the medical service server determines a disease state of the human body on the basis of the electrocardiographic analysis result, the magnetocardiographic treatment data and the pseudo electrocardiogram and magnetocardiogram, and generates definitive diagnosis data through comparison among the real magnetocardiographic treatment data, the electrocardiographic analysis result, the disease state, and a diagnosis criteria. The definitive diagnosis data is provided to the client.
