It has been very difficult and inefficient to implement data synchronization in the multimedia information systems until now, because most data synchronizations have been implemented by ad hoc methodologies. In this paper, we propose a new synchroniation methodology implemented by scheduling using monitor. If users definece the temporal relationships of media data using high level user interface, then the monitor selects media data started at that time and controls setup time and precessing time. The scheduler determines the scheduling method or selected media data and adjusts the synchronization among them.

The condition of a high voltage motor was monitored with the motor performance monitor (MPM) at the motor control center. The MPM detected defects in the rotor bar and end ring and input power according to motor and load conditions. The assessment of the condition of a coal pulverizer motor indicated it was clearly in good condition in terms of the rotor bars, over voltage, and motor performance. However, the side bands at frequency, 56.48 Hz indicated existence of rotor end-ring fault. The large torque ripple indicated abnormal operating conditions. After visual inspection, it has been observed that an impeller blade of the circulating water pump was broken off causing the irregular torque pattern.

실시간 시스템은 높은 수준의 안정성을 요구하는 시스템이다. 실시간 시스템에서 오류는 잘못된 응답 뿐만 아니라 시간적으로 늦은 응답도 오류를 발생 시킬 수 있다. 따라서 실시간 시스템의 안정성을 보장해 주기 위해서 실시간 태스크의 시간 제약에 대한 모니터링 및 오류발생 시에 오류를 처리해 줄 수 있는 기법이 필요하다. 본 논문은 Timed Conformance Monitor를 통해서 실시간 태스크가 시간의 제약을 만족하는지를 분석하고 또한 분석 결과에 따라 오류를 처리할 수 있는 Fault Handler를 추가하여 실시간 시스템에 대한 Fault Tolerance를 보장해 줄 수 있는 기법을 제시한다.

The verification portion of SoC design consumes about 70% of total design effort. To reduce the verification effort and time, it is necessary and desirable to raise the level of SoC design verifications level from the signal or cycle level to the transaction. This paper describes a generation method of transaction monitor modules that monitor interface signals, logging the transaction executions, and report transaction errors. The input of the generation method is a transaction-oriented interface protocol description.

Driver IC is one of the key components on the LCD monitor and LCD/TV. The function of the driver IC is to transfer and forward the input signals to LCD panel module. Inside driver IC, there are several operating units which process the input signals and generate the appropriate size and resolution to the LCD panel module. LCD panel module will display these input signals. However, there are some difficulties which driver IC designer, LCD monitor and LCD/TV maker will face. Thus, this article addresses the function and difficulties on driver IC.

By varying the beam current of a color CRT(cathode ray tube) monitor, the misconvergence, spot size, display luminance, and chromaticity coordinate of a white pattern were measured at 4 screen positions. The misconvergence was measured with a linear CCD (charge coupled-device). The resolution was obtained by using SQRI (square root integral) method. The misconvergence of a color monitor was not influenced by the beam current but by the screen position. The misconvergence on a screen perimeter caused the resolution to decrease.

This paper deals with the finite element model of the monitor for the simulation of directional free drop tests such as backward, sideward, edge and vertex drop. The model was made for an unconditional stable solution for the explicit integration algorithm. The general behaviors at the time of impact were found to well correlate with the actual situation in terms of acceleration, displacement, contact force and stress of monitor components even though the experiment of the associated drop is performed for the validity of the model.

In this paper, we describe the design methodology and specifications of the developed module-based bedside monitors for patient monitoring. The bedside monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases, each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and SpO with plethysmograph.raph.

We have developed a 2D-3D convertible 7" autostereoscopic mini-monitor with high 3D quality, in which the parallax barrier LCD is attached on the TFTLCD. The excellent optical performance was achieved by design of the ghost free barrier and precise assembly between the barrier layer and the TFT-LCD panel. Our design principle and fabrication technology suppressed 3D cross-talk and improved viewing angle. In this paper, the design and fabrication process of the 3D mini-monitor are described. The evaluation for the 3D performance is also discussed.
