In this paper, a new multi-view 3D video communication system for real-time Reality teleconferencing application is proposed by usin gthe IEEE 1394 digital cameras, Intel Xeon server computer system and Microsoft's DirectShow programming library and its performance is analyzed in terms of image-grabbing frame rate and number of views. The captured two-view image data is compressed by extraction of disparity data between them and transmitted to another client system through the communication network, in which multi-view could be synthesized with this received 2-view data using the intermediate view reconstruction technique and displayed on the multi-view 3D display system. From some experimental results, it is found that the proposed system can display 16-view 3D images with a gray of 8bits and a frame rate of 15fps.

The monitoring system is an absolutely required system for improving a performance to consider the situation for the hybrid generation of the photovoltaic (PV) and wind power (WP) energy experimental research complex. This system is to monitor with the railroad switching point heating system using LabVIEW to the hybrid generation of the PV and WP. The monitoring system of this paper is a program monitoring the hour, day and total of the voltage and current that made from the hybrid generation of PV and WP. In experiment, we acquired the power data according to time at the day of PV and WP. We have confirmed the possibility of the real time monitoring system using LabVIEW with the railroad switching point heating system as the hybrid generation of the PV and WP.

Recently, automatic control or application of measuring instrument with computers is rapidly increasing. In this paper we designed automatic incubation system that has functions of control and monitoring of measuring instrument, analysis of measured data, and automatic control by using LabVIEW graphic program that can easily collect, control, analyze, and apply data. Then to inspect the system we produced Incubator. Internal environment is measured by a sensor and each device is setting and controlled to create the optimum environment after finding hatching environment of selected individual from Database file for incubation. Through this functions, problems of hatching rate and quality that were affected by minute change of hatching environment are dealt successfully with, and retrenchment of labor and cost is expected as well.

In this paper, we suggest the object-oriented methodology for the design and implementation scheme for the program development in the application of control and instrumentation such as the detection system of RFID defective tags which needs the embedded programming. We apply the design methodology of UML in the system design phase, and suggest the implementation scheme of LabVIEW programs using LVOOP(LabVIEW Object Oriented Programming)in which make it possible to write the object-oriented programming. We design the class diagram and the sequence diagram using UML, and write the classes of LVOOP from the designed class diagram and the main VI from the sequence diagram, respectively. We show that it is possible to develop the embedded programs such as the RFID application through the implementation example of the detection system of RFID defective tags in this paper. And, we obtain the advantages based on the object-oriented design and implementation using the LVOOP approach such as the development of LabVIEW programs by adding the classes and the concept of object of the object-oriented language to LabVIEW.

This paper will show how to design home network management system in the wired/wireless environment using graphical language LabVIEW, J2ME and to apply the design to monitoring and remote controling for the information devices at home. This paper also provides with efficiency of device control and current status check according to the circumstances of administrators by constructing the wire/wirelessly integrated administration system. It means the administrators can access to central administration server and acquire the control right through web being able to operate the system with flexibility and can access to the server without computer whenever, wherever they need to control and administrate it through this wired/wireless unit easily.

Recently, acgis of authentication and crcator's copyright has become a matter of great concern by the diffusion of multimedia technique and the growth of the internet and the easily duplicated property of digital data. Consequently, many active researches have been made to protect copyright and to assure integrity by inserting watermark into the digital data. In this paper, watermark is repealed through the entire image and adapted to the content of the image. Achieved by an underlying process of transforming the digital image to the frequency domain by wavelet transform, which has three (vertical, horizontal, diagonal) directions and Multi-resolution features, and then choosing frequency area inferior to the human perceptibility and significant for invisible and robust watermark. We realize wavelet based image watermarking using Machine Vision of LabVIEW.

Cogeneration means the highly energy-efficient generation system that improves energy ratio by generating electricity and heat, and it really affects the improvement of overall efficiency by using industrial process, district heating, and hot-water supply etc. after the energy produced through supplying power to system collects. This thesis indicates the screen of cogeneration flow in LabVIEW and the heat power control system that can be in long-distance control of a district energy system using TCP/IP. We simulated on four computers so that the heat power control system proves long-distance control possible.

It has been required to develop a defect detection system to perform defect detection capabilities after the bonding process in the production of RFID tags. However, we are difficult to design a system with understanding the characteristics of RFID tags and design concepts. Also we are difficult to modify even minor changes in features. In this paper, we design the defect RFID detection system using UML and object-oriented design techniques. We suggest the method for apply the UML Diagram to LabVIEW OOP and the technique for redesign the effect detection system's changes.

In general, electronic conveyor scales are installed in a relatively distributed manner on the crushed rock and sand production site. It is one of the time-consuming and difficult engineering works to monitor and control the plant operation status such as the management of measuring data, malfunction of belt conveyor, and fault of electronic conveyor scale. Therefore, to alleviate the inefficient problems and to monitor the operating plant in the online and remote control room, a remote calibration and real-time monitoring system, which is practically applied to the electronic conveyor scale system and verified by onsite experiment, is developed based on the LabVIEW.

The computer technology and internet have the potential to provide a highly interactive and powerful learning environment for engineering disciplines. Many academic courses that teach engineering subjects have already begun incorporating virtual instruments as teaching and learning tools. This paper introduces the concept of the virtual instrument and reports some of the LabVIEW software applications in several universities. Finally the paper contemplates the future trends on the remote laboratory via the internet for engineering education.
