  • Interlace textured yarn was developed in order to increase weaving process efficiency. Today, interlace texturing is very useful method of manufacturing the high added value compound yarns for new synthetic fabrics. In this research, new silky type high added value compound yarns were. manufactured by interlace texturing technology and tested their properties. The object of this research is to investigate the relationship between interlace textured yarn properties and processing parameters that is air pressure, yarn tension and take-up speed. The original filament yarns used were TTD(Thick & Thin Semi-Dull) 110d/72f and SCD(Semi-Dull Cation Dyeable) 75d/36f. 27 specimens were manufactured and tested for their physical properties-nip density, tensile properties, multi-step shrinkage test and surface structure by SEM. The air pressure was main process condition to change properties of interlace textured yarns. And interlace textured process had influence on weaving preparation process, weaving, knitting and so on. It has some influence on shrinkage properties of dyeing and finishing processes.

  • 본 논문에서는 ELA(Edge Line based Average) 알고리즘이 잡음 영상에서 IPC할 때 생기는 문제점을 개선하는 알고리즘을 제안한다. 먼저 잡음을 제거하는 필터링과 동시에 잡음이 없는 원화소의 크기와 잡음의 크기를 추정한다. 이에 따라 잡음의 크기를 고려하여 ELA 방법과 수직보간 방법에 가중치를 주어 보간값을 구한다. 이 후 잡음이 존재할 경우 포스트 필터링(Post Filtering)을 거쳐 잔재해 있는 잡음을 제거해준다. 실험결과 제안하는 알고리즘이 기존 ELA 알고리즘들 보다도 향상된 결과를 보인다.

  • Fall-arrest systems(maximum arrest force and allowable free-fall) have been widely applied to provide a safe stop during fall incidents for various industrial activities. Fabric structure affects on the mechanical properties of shock energy absorber. The object of this study is to perform the basic research for the evaluation of the capacity of fall arrest energy absorber in relation to the different interlace yarn density. In this work, pack style energy absorber was prepared by weaving 10 types(Interlace yarn density used high tenacity PET 1000D : 60, 59, 58, 57, 56, 55, 54, 53, 52, 51). The paper presents the results of theoretical investigations of the performance of adjustable absorber during fall arrest. Dynamic load tests based on the EU fall protection equipment standard(CE : EN355:2002) were conducted. Results showed that the maximum arrest force by dynamic load test of energy absorber was satisfied with global standard(below 6,000N). Also, Maximum allowable free-fall of energy absorber showed below 1.75m.

  • In this paper, we propose a new IPC(Interlace to Progressive Conversion) method based on ELA(EDge Line based Average) interpolation using detecting the reliable edge direction. Existing ELA algorithms execute linear interpolation using edge direction without considering noises. In noisy images, these algorithms degrade quality because if interpolation based on the wrong edge direction. Out scheme is able to solve the problem of existing ELA algorithms in noisy images. First, filter a noisy pixel and estimate sizes of the noiseless orginal pixed and the noise, repectively. Then, considering the size of the noise, calculate weights of ELA and vertical interpolation. If noises exist after IPC, these could be eliminated by post filtering. The experimental results show that our proposed algorithm has about $1{\sim}2$ dB better performance than those of existing ELA algorithms.

  • A current TV out format is quite different from that of HDTV or PC monitor in encoding techniques. In other words, a conventional analog TV uses interlaced display while HDTV or PC monitor uses Non-interlaced / Progressive-scanned display. In order to encode image signals coming from devices that takes interlaced display format for progressive scanned display, a hardware logic in which scanning and interpolation algorithms are implemented is necessary. The ELA(Edge-Based Line Average) algorithm have been widely used because it provided good characteristics. In this study, the ADI(Adaptive De-interlacing Interpolation) algorithm using to improve the ELA algorithm which shows low quality in vertical edge detections and low efficiency of horizontal edge lines. With the De-interlacing ASIC chip that converts the interlaced Digital YUV to De-interlaced Digital RGB is designed. The VHDL is used for chip design.

  • Although the existing NTSC TV standard is highly sophisticated, it has some inherent problems. One of these problems is interlaced scanning, which yields a poor result in terms of the vertical picture resolution. In this paper, we have proposed the interlace to progressive conversion method using the pseudomedian filters. Since the proposed method is processed in the intra field is different from the conventional method using the median filter, it is implemented without using field memory and its performance is same or nearly the same as the corresponding performance of the median filtering method. The performance of the proposed method has been compared with that of conventional methods through computer simulation.

  • 본 논문에서는 Windows Embedded CE의 스트림 인터페이스 드라이버(Stream Interlace Driver)를 개발하는 새로운 방법을 제안하고자 한다. Windows Embedded CE 디바이스가 부팅되면서 스트림 인터페이스 드라이버는 디바이스 매니저에 의해 메모리로 로프(Load)되고 디바이스가 꺼질 때 메모리로부터 언로드(Unload)된다. 디바인스 드라이버를 변경하여 다시 적용한 후 결과를 확인하고자 할 때 OS 바이너리 이미지를 새로 생성한 후 이미지를 다시 다운로드 하거나 드라이버를 플랫폼 빌더에서 등록한 후 해당 디바이스를 재 부팅하고 Kernel Interlace Layer(KITL)를 사용하여 그 결과를 확인할 수 있다. OS 바이너리를 새로 만드는 경우 이미지 생성과 다운로드 시간이 많이 소요되고, KITL를 사용하는 경우 매번 부팅 하는 과정을 반복해야 하기 때문에 시간이 더 소요된다. 본 논문에서는 데스크탑에서 Remote API를 이용하고 Stream Device Driver를 디바이스에 전달한 후 그것을 Remote API를 사용하여 로드하고 언로드하는 구조를 제안한다.
