This study provide Car driver with car sensor information which is car trouble code in engine and many sensors. This provide car manager with many information of car sensors when we go to vehicle maintenance. This system consist of embedded linux system which uses RS232 and EML327 for CAN communication of car system. Finally this is a lot of application for embedded linux system which get sensor informations of car control sensor system.

In this paper, we propose a three dimensional distance measurement method for a stereo system by using web cams. Using a parallel stereo system, a robot gets two images from each webcam and equalize brightness of both images. And we suggest an image processing method such as labeling, isolating an object from background and finding center of an object. We also propose a method of calculating the focal distance by using least square algorithm based on triangulation and we can reduce calculation error by this method. From experimental results, we show that the proposed method can be effective for 3D distance measurement.

In this paper, we address to develop a port container management system using RFID, which is one of the main technologies in ubiquitous. Our system is designed and implemented based on the following technologies: a port gate automation using RFID for container identification, web programming for both communication of the gate and deposit/delivery of a container, and wireless embedded router technology for both port container network platform and cram terminals. The developed system using RFID will be expected to use in main part of the port logistic management system aimed to the intelligent port.

인터넷의 발달로 인하여 웹을 통한 문서 송수신이 많아지면서 종래의 인쇄 매체 상에 기술된 문서들은 점차 전자문서화 되기 시작했다. 이러한 문서들을 서로 다른 시스템 사이에서 상호 교환하기 위해서는 사용자가 원하는 논리적 구조를 태그로 구현할 수 있는 정형화된 문서 형태가 필요하다. 본 연구에서는 XML 형식의 메일에 XSL 문서를 임베디드하여 보내는 XSL 메일 전송 기법을 제안하고자 한다. XSL 메일 서버를 통하여 수신된 메일은 XML과 XSL 형식에 따라 XSL 메일 데이터베이스에 따로 저장되기 때문에 분석이 매우 용이하다는 장점을 가지고 있다. 임베디드 XSL 메일은 HTML 형식의 문서와는 달리 얻고자하는 element를 메일로부터 쉽게 분리해 낼 수 있으므로 대량의 메일을 수신한 경우 메일들을 효과적으로 관리할 수 있는 장점이 있다.

We made a HTTP server using 8 bit microprocessor. It was TMP84C015 which applied a 180 core and RTL8019AS was installed for an ethernet physical layer. Assembly language was used to optimize a performance of the MPU, to overcome an restriction of memory size and to maximize the throughput of packet using TCP, UDP, IP, ICMP and ARP protocol. We used LabVIEW to verified the each protocol on the client side.

오프라인에서만 가능했던 일들이 인터넷 속도의 향상으로 온라인을 통한 실시간 제어가 가능해지고 있다. TCP/IP를 기반으로 이루어지는 경우 대개 소켓을 이용한 PC기반에서 해석되어 지고 처리되어 진다. 본 논문에서는 PC기반의 원격제어 시스템을 임베디드화하여 온실시스템에 적용해 봄으로써 시스템의 안정성과 효율성에서 우수한 시스템을 구현하려고 한다. 이를 위하여 임베디드 시스템은 웹서버의 기능을 가진 HelloDevice 1300보드를 이용하였다. 실질적인 제어물의 제어를 위해서 제어기를 HelloDevice 1300보드와 시리얼을 통하여 통신하였다. 이와 같은 시스템을 구현하여 온실시스템의 자동화에 관한 실효성을 검증하였다.

인터넷과 정보통신 기술의 발달로 네트워크의 활용 범위도 넓어지게 되었다. 이에 따라 감시용 모니터링 시스템의 응용분야가 다양해졌을 뿐만 아니라 시스템에 대한 요구사항도 많아지고 되었다. 특히 소규모의 매장에서의 응용을 비롯한 무인화 시스템의 확산은 일반인이 쉽게 다룰 수 있는 보급형의 저가 감시시스템의 개발을 요구하고 있다. 본 연구에서는 저렴하고 다양한 부가서비스가 가능하며 인터넷에 쉽게 접속할 수 있는 감시시스템을 구현하였다. 리눅스 기반의 임베디드 리눅스 시스템을 이용한 웹캠 서버를 구축하였다. 구현된 시스템은 웹서버를 통해 실시간 모니터링 기능이 잘 동작하는 것을 확인하였다.

In this paper, we propose the system that simultaneously controls objects in virtual reality and objects in real environments using brain waves. We propose a system that measures brain waves to grasp the user's concentration and quantifies them to raise or lower virtual and real objects. We implemented a web-based virtual reality system and an embedded system based on a raspberry pi for test of design. It was confirmed that the control of virtual and real objects is possible using BCI. The result was that it was possible to develop various contents using this.

In this paper, We propose the real-time monitor and control mechanism based-on web service for intelligent robot called URC(Ubiquitous Robotic Companion). URC is intelligent robot designed to interact with external digital device that can communicate through wire or wireless. In this paper, we designed the result of this study into the target robot called NETTORO and proved its practical worth. we optimized web-service technology in Embedded system environment so that can monitor and control indoors in remote place through acquired information from various sensors / actuators and then we designed. Also, we described command port to WSDL, so that can apply variously such as web server or application program in AXIS engine through gSOAP transmission protocol.

Web streaming environment need a suitable video playback service technique, a streaming technique for real-time delivery and an efficient control technique due to its limited environment. In this paper, we propose an effective control technique for real-time media stream playback as a connection technique between the high-quality media player and web browser based on Linux environment. The proposed stream control technique presents control data through 050 on media playback screen of web browser, and process the user's input data. It acts GUI-independently, and is designed considering addition and extension for control data.
