As the price-performance ratio of embedded PCs improves, the benefits of the PC-Fi can be maximized by designing an embedded PC-Fi system. In this paper presents the design of an embedded PC-Fi that can be manipulated by a remote controller based on mobile devices such as smart phones or tablets. Additionally, an interactive control system and its GUI, through which the user can select and play music as they like at ease, are presented. The case that a large amount of music is stored in the PC-Fi system requires a function allowing the user to easily select the music they want to listen to. In order to implement this function, a DB containing detailed information of each track can be used to find the location of the desired music with keywords provided by the user. In this proposed system, the embedded PC-Fi system and remote controller are mutually connected via a WiFi network, and more than one user can remotely control the embedded system with their own mobile device.

In this paper, a new remote terminal unit(hereafter RTU) is proposed to manage a wide range of applications and a variety of sensors (eg, pressure, water quality, temperature and humidity sensors, the amount of pollutants, $CO_2$, etc.) to monitor and control the facility such as water treatment plant, intake and effluent pumping station, water tank and distribution network. Fault status of local sensor devices and network are alerted by using the embedded fault handling capabilities of the RTU in the system and also sent to the fault handling server, by which fault can be easily monitored to users. The developed system was applied to one of K-water branch offices in Geoje city and improved its reliability and stability for controlling and monitoring water facility.

In this paper, we design a mobile phone based remote control system for PC using SKT WPAN platform and compare the presented platform with that of Windows Mobile. The usability of WPAN is one of the main issues which should be considered for the ubiquitous services. For easy development and easy use of the WPAN applications, SKT WPAN platform provides abstract WPAN APIs and WPAN Application Manager for ubiquitous services. In this paper, we implement a remote control application using the WPAN platform and show the validity of the platform comparing with other platforms. In the implemented application, we use WPAN abstract APIs on the mobile phone side and a general Bluetooth APIs on the PC for a connection between phone and PC. Through the implementation and comparison, we show that the WPAN application can be easily developed with WPAN platform.

Embedded device that can support mobile computing environment has been popular recently. In this study, we propose a new robot application based on embedded device to control a mobile robot using a touch-based remote interface with information display of robot trajectory and sensors. We developed the robot application using Microsoft's.Net Compact Framework and Zigbee data communication with Windows CE kernel based embedded device. In experiment, we evaluated the feasibility and the effectiveness of the proposed system by showing a remote robot control using touch interface and a information display of the robot.

This paper describes a remote monitoring system of temperature controller for cold-storage, of farm produce. In the cold-storage, it is important that farm produces are fresh. Unfortunately, when an operator goes out from the cold-storage temperature change could be occurred due to the various reasons, for an example, a valve of cooler is broken. The temperature change results in a serious problem of the quality of farm produce. To prevent the problem, the operator has to look to the current state of the temperature of the cold-storage, even he is in long away. Thus, the monitoring system to show the temperature should be required to the operator who can move away. Therefore, this paper propose of the remote monitoring system of the temperature. The proposed system is expected to help the operator's facilities, and the management of farm produce.

This thesis is dealing with conveyer remote monitoring and control system for shoes process formed by client/server, which is based on Web. Modules for watching and controlling images in a remote by client is manufactured under JAVA, and conveyer server for real-time controlling is founded on RTLinux. And device driver and APIs are developed based on it. Through both manufacturing these software and LEGO-based prototyping, it would present the real-time conveyer controlling system founded on Web and 3-dimensional stereo camera to be applied to industrial spots.

In this paper, a game control system was constructed, in which a game was controlled by a remote joystick connected with a power line by the power line communication (PLC) method. The structure of the system was that the connection line between the remote joystick and a PC, and the PC and an audio play device was the home power line. And, the communication data rate between them was 2400 bps. The Polling communication technique was used for the PC to read the joystick's control commands, and to send some acoustic informations to the receiver PLC device. A game was programmed, in which an aircraft was moved according to the joystick's left, right, up, and, down direction, and was shooting its missile after the joystick's shooting button was pushed. The communication delay of about 100 msec between them didn't cause any big problem in playing the game.
