Owing to revolutionary developments in automobile technologies, a variety of advanced vehicles - hybrid vehicle, hydrogen fuel-cell vehicle, electric vehicle, etc. - emerges recently. The safety is getting more important for developing automobiles. The electro-magnetic compatibility has to be assured, since those advanced vehicles are equipped with various new electronic systems. Electro-magnetic compatibility tests, in general, consist of an EMI(electro-magnetic interference) test and an EMS (electro-magnetic susceptibility) test. We investigated the susceptibility test method suggested in KMVSS (Korean Motor Vehicle Safety Standard) as the EMS test method. A series of experiments results that the above test method should be partially revised to comply with a Korean governmental standard method. In this paper, the some directions of modifications are presented to enhance the quality of the above EMS test method.

Development of IT and electronics industries has make our life more convenient, yet at the cost of radio communication noise, malfunctioning of electronic appliance and risks against human health all resulting from EMI. Many states are tightening their EMI (Electro Magnetic Interference) regulations around the world and the EMI regulatory measures are likely to increase in terms of targets and types. Against this backdrop, this paper aims to introduce fundamental and adequate EMI countermeasures encompassing product production cycle from design to production stage.

A recently constructed commercial ship is a complexive integrated system like a small city in which has a generator, power distributing facilities, various radio equipments and high power circuit breakers are installed. Therfore it could make a malfunction of the microprocessor in the various control units which are so important during the ocean voyage of larger ship. This paper has studied whether is properly required or not on the view of the actual electro magnetic compatibility status on the electromagnetic interference and suceptibility test requirments listed on the IACS (International Association of the Classification Society). Through these results, we are looking forward to the new suggestions of the Electro Magnetic Compatibility test in order to reduce the malfunction in the ship regarding test item, test level, and test condition.

차량용 멀티미디어 시스템은 자동차 산업에 있어서 매우 중요한 요소 중 하나이다. 특히, 프리미엄 고속버스와 같은 고급상용차에서의 멀티미디어 시스템은 더욱 중요하다. 우리는 본 논문에서 MOST150을 기반으로 MEP(MOST Ethernet Packets)을 이용해 프리미엄 고속버스용 멀티미디어 시스템 구조를 제안했고, Prototype을 설계 및 구현했다. 제안한 시스템 구조를 구현하기 위해 멀티미디어 시스템이 운용될 수 있는 I.MX6기반의 Board를 설계했다. 소프트웨어는 Open Source Platform인 Android를 기반으로 프리미엄 고속버스용 멀티미디어 시스템을 설계했다. MOST는 고속의 멀티미디어 네트워크 기술이며, 차량의 멀티미디어시스템 설계에 사용된다. 기본적으로 링 토폴로지(Ring Topology)를 사용하고, 최대 64개의 MOST 장치를 연결할 수 있다. 또한 MOST 네트워크는 광모듈(POF)을 이용해 통신하기 때문에 EMII(Electro-Magnetic Interference) 및 EMC(Electro-Magnetic Compatibility) 요구조건을 충족한다.

EMC (Electro Magnetic Compatibility) of the electrical railway must be ensured for safety of passenger. Maglev trains has not friction between the wheels and the rails because levitation by an permanent magnets, electromagnets and superconducting magnets etc. So, it is advantageous to maintain a high speed without noise and vibrations. In this paper, we investigated that the magnetic field of the before and after installation electromagnetic waves absorber in order to analyze the effects of electromagnetic waves. The theoretical analysis of the electromagnetic wave absorber was simulated using finite element method. The magnetic field properties of electromagnetic waves absorber were measured by EMI (Electro Magnetic Interference) test receiver.

It is quite essential that requirements allocation and analysis would be done for the electromagnetic compatibility (EMC) of all units when designing a satellite. Although KOMPSAT-2 inherits relatively large portions of the electrical designs from KOMPSAT-1, it has a new instrument and different combinations of sensors and actuators as well as their driving circuitry. Many requirements for the electromagnetic compatibility were modified and newly allocated for KOMPSAT-2. Naturally, they must be justified through analyses from the early stage of the program. In this paper, the EMC compatibility requirements for KOMPSAT2 are presented and verified for their suitability. In addition, some results, which were obtained from various analyses, are presented and discussed.

The major problem encountered in satellite design is EMI (Electro-Magnetic Interference) and EMC (Electro-Magnetic Compatibility). Here, our focus is on the effects of protons on the electronic system. The SEU (Single Event Upset) results from the level change of stored information due to photon radiation and temperature in the space and the nuclear power plant environment. The impact of SEU on PLD (Programmable Logic Devices) technology is most apparent in ROM/SRAM/DRAM devices wherein the state of storage cell can be upset. In this paper, a simple and powerful test techniques is suggested, and the results are presented for the analysis and future reference. The test results are compared with that of JPL test report. In our experiment, the proton radiation facility available at KIRAMS (Korea Institute of Radiological Medical Sciences) has been applied on a commercially available SRAM manufactured by Hynix Semiconductor Company.
