  • In this paper, the automation of sweeping center setting for wavelength swept laser used in SS-OCT has implemented. For 3 regions where the initial FFP-TF pass wavelength can be located, each different DC voltage pattern is applied to FFP-TF. Through its performance test to the laser, fast and exact setting to sweeping central wavelength, flat sweeping with ${\pm}0.5dB$ fluctuation range, and 10 mW average optical power were obtained. This shows that the realized automatic setting process can replace an inconvenient manual setting operation used for current wavelength swept laser. Additionally it cuts costs for optical spectrum analyzer necessary to laser spectrum monitoring.

  • This paper is about the development of automatic inspection system of welded nuts on Support hinge using machine vision for the improvement of working condition. Until now, projection welding process was performed by operator. Also, inspection of welded nuts is performed manually and recorded by the operator's naked eye. So these processes caused the produce of poorly-made articles. To improve this manual operation, inspection system using machine vision is introduced. Test algorithm, lighting system and program showed good results to the designed inspection system and led to the increment of productivity.

  • Gabion can be used for the purpose of preventing overflow of river and side loss of road. However the manufacturing process of the gabion is manually controlled especially to the joining process at the terminal part of gabion with small diameter wire. In this paper automatic feeding guide system was designed and fabricated to make automation. The fabricated system was tested in the factory level. Pneumatic system was considered as the main idea of the feeding system. 3/2-way and 5/2-way manual control valve, eight double-acting cylinders were used. Based on the theoretical simulation and actual test the fabricated system was well controlled. The system was applied to the patent.

  • This study restoration worker for dispersion relay in R-Type fire alarm system. Restoration worker very good instrument for an fire system inspector. When inspector check for fire system someone need reset for fir system to normal state. This chain of action is frequent and troublesome. In this case, If we can automatic reset for fire system it's restoration worker. This paper settlement on the problem for reset fire system. Design, make grabber for restoration worker. The test offer proof possibility restoration worker.

  • This paper proposes a new building segmentation method from 1m resolution imagery using an Active Contour Model, known as "Balloons". The original balloons, which was designed by Cohen(Cohen, 1991) to extract features from medical images, are modified for building segmentation. The proposed method consists of two phases. Firstly, building boundaries are extracted by balloons with a given position on buildings from an operator. Since balloons actively adjust their shapes according to the boundaries, there is no more shape limitations on detecting buildings. Secondly, buildings are segmented by connecting the corners detected from the building boundaries, because most buildings, which are man-made objects, are effectively described by polygons. The test results show that most buildings are segmented efficiently and easily. The proposed method is new and timely as 1m resolution spaceborne imagery will be available in the very near future. The proposed method can be used fur operational building segmentation from such imagery.

  • 최근 산업계에서는 급변하는 사용자의 요구사항을 반영하면서, 경쟁력 있고, 경제적인 소프트웨어를 개발하기 위해서 EJB 컴포넌트 개발 방법을 채택하고 있다. 그러나 EJB 컴포넌트를 테스트하는 것이 기존의 자바 클래스의 테스트보다 더 많은 노력이 필요하고, 어려운 작업이기 때문에 많은 경우에 EJB 컴포넌트에 대한 테스트가 수행되지 않는다. 이에 본 논문에서 EJB 컴포넌트의 테스트 케이스 생성을 자동화 할 수 있는 방법을 제안한다. 이는 EJB 컴포넌트 개발 시 만들어지는 Deployment Descriptor로부터 컴포넌트에 대한 정보를 추출해내고, 이를 기반으로 테스트 케이스를 자동으로 생성하는 방법이다.

  • In order to comply with the Federal Motor Vehicle Safety Standard(FMVSS) No. 208 that has been in force since September 2003, an automatic airbag suppression system has become an essential option for detecting and protecting infants and children seated in the front passenger seat of vehicles in the U.S. market. MOBIS has developed the world's first weight-based OCS under the name NWCS. NWCS is composed of two sensors and ECU. It is sub-packaged in order to minimize the seat structure deviation. In this paper, technical features, robustness and performance of NWCS are summarized and discussed.
