최근 차량 내부의 전장장치 사이에 운전자의 편의성의 요구 수준이 높아지고 있으며 이에 대응해 상호통신을 위한 차량용 네트워크 기술이 빠르게 발전하고 있다. 이에 따라 이들 인포테인먼트 시스템 중 최적화된 내부 통신기술이 필요하게 되었다. 차량용 네트워크인 MOST(Media Oriented Systems Transport)는 오디오, 비디오 신호를 동기적으로 전송할 수 있는 자동차용 멀티미디어 시스템에 가장 광범위 하게 사용되고 있는 네트워크이며 넓은 대역폭과 오디오, 비디오 데이터의 실시간 전송 및 코딩을 지원한다. Windows CE는 다양한 라이브러리를 지원함으로써 다양한 GUI 및 네트워크 프로젝터 개발이 가능하다. 이러한 기술적 변화에 맞춰서 본 논문에서는 Windows CE 6.0 기반의 보드와 차량용 인포테이먼트 네트워크인 MOST 네트워크를 이용하여 MOST 네트워크 상태를 관리할 수 있고 MOST 네트워크 동작 및 정보, 상태 등 다양한 정보를 한눈에 확인할 수 있는 시스템을 구성하였다.

In this paper, we propose the implementation techniques of IC card chipset that is compatible with international standard ISO-7816 and supports WindowsCE operating system to expropriate various electronic cash and credit card. This IC card interface chip set is composed with 32 bit ARM720T Core and AES(Advanced Encryption System) cryptography module for electronic commerce. Six IC card interfaces support T=0, T=1 protocol and two of them are used to interface with user card directly, the others are used for interface with SAM card. In addition, It supports a LCD controller and USB interface for host. We improved the performance about 70% than software based It card chip set and verified using Hynix 0.35um process.

To match the charge induced by the insulators $CeO_2$ with the remanent polarization of ferro electric SBT thin films, areas of Pt/SBT/Pt (MFM) and those of $Pt/CeO_2/Si$ (MIS) capacitors were ind ependently designed. The area $S_M$ of MIS capacitors to the area $S_F$ of MFM capacitors were varied from 1 to 10, 15, and 20. Top electrode Pt and SBT layers were etched with for various area ratios of $S_M\;/\;S_F$. Bottom electrode Pt and $CeO_2$ layers were respectively deposited by do and rf sputtering in-situ process. SBT thin film were prepared by the metal orgnic decomposition (MOD) technique. $Pt(100nm)/SBT(350nm)/Pt(300nm)/CeO_2(40nm)/p-Si$ (MFMIS) gate structures have been fabricated with the various $S_M\;/\;S_F$ ratios using inductively coupled plasma reactive ion etching (ICP-RIE). The leakage current density of MFMIS gate structures were improved to $6.32{\times}10^{-7}\;A/cm^2$ at the applied gate voltage of 10 V. It is shown that in the memory window increase with the area ratio $S_M\;/\;S_F$ of the MFMIS structures and a larger memory window of 3 V can be obtained for a voltage sweep of ${\pm}9\;V$ for MFMIS structures with an area ratio $S_M\;/\;S_F\;=\;6$ than that of 0.9 V of MFS at the same applied voltage. The maximum memory windows of MFMIS structures were 2.28 V, 3.35 V, and 3.7 V with the are a ratios 1, 2, and 6 at the applied gate voltage of 11 V, respectively. It is concluded that ferroelectric gate capacitors of MFMIS are good candidates for nondestructive readout-nonvolatile memories.

Involuntary movement of internal organs by respiration is a factor that greatly affects the results of radiotherapy and diagnosis. In this study, a moving phantom was fabricated to simulate the movement of an organ or a tumor according to respiration, and ¹⁸F-FDG PET/CT scan images were acquired under various respiratory simulating conditions to analyze the movement range of the tumor movement by respiration, the level of artifacts according to the size of the tumor and the maximum standardized uptake value (SUVmax). Based on Windows CE 6.0 as the operating system, using electric actuator, electric actuator positioning driver, and programmable logic controller (PLC), the position and speed control module was operated normally at a moving distance of 0-5 cm and 10, 15, and 20 reciprocations. For sphere diameters of 10, 13, 17, 22, 28, and 37 mm at a delay time of 100 minutes, 80.4%, 99.5%, 107.9%, 113.1%, 128.0%, and 124.8%, respectively were measured. When the moving distance was the same, the difference according to the respiratory rate was insignificant. When the number of breaths is 20 and the moving distance is 1 cm, 2 cm, 3 cm, and 5 cm, as the moving distance increased at the sphere diameters of 10, 13, 17, 22, 28, and 37 mm, the ability to distinguish images from smaller spheres deteriorated. When the moving distance is 5 cm compared to the still image, the maximum values of the standard intake coefficient were 18.0%, 23.7%, 29.3%, 38.4%, 49.0%, and 67.4% for sphere diameters of 10, 13, 17, 22, 28, and 37 mm, respectively.

As the practical range of SAW Device extended into various fields including physical sensor, chemical sensor and ID Tag, the platform for various SAW Devices is required more than ever. While SAW ID or Sensors advanced remarkably, the development of platform which applies to SAW Sensor left much to be desired. Therefore this paper represents the SAW platform in order to use SAW ID such as ID Tag or Sensors more conveniently. The SAW platform consists of a RF module which can recognize SAW ID and a main module which has a hish performance processor in order to process the response signal of SAW ID. The main module which has a high performance processor is designed by GUI environmental type to ensure that users are able to use the platform more easily. In this paper, the SAW platform, which is based on ARM9 core processor, used Windows Embedded CE 6.0 OS which brings friendly interface to users. Also the developers can make less effort to design various applications with sensors.
