Remote laser beam welding (RLW) has the benefits of high speed and high quality welding, especially as applied to automotive industry. RLW is designed in a way that end effecter and head of scanner move simultaneously, and require the compensation for the motion of end effecter in order to weld proper position. In this paper, we show the algorithms of RLW that enable the end effecter to synchronize with scanner based on time. The proposed method consists of two algorithms. These algorithms make it possible for the moving end effecter to weld on desired place. The effectiveness of the algorithms is shown by experiments.

This paper describes the improvements made on hardware and software of the remote controller for realistic contents. The controller can provide vibrotactile feedback which uses both of a voice-coil actuator and a vibration motor. A vision tracking system for the 3D position of the controller is optimized with respect to the marker size and the camera parameters. We also present the improvements of motion recognition due to the effective motion segmentation and the fusion of vision and acceleration data. We apply the developed controller to realistic contents and validate its usability.

When we design the control system used Programmable Logic controller(PLC), if we program a Sequential Function Chart(SFC), It is easy to understand the sequential flow of control, to maintenance the controller and to describe a program. SFC language is programmed by a single sequence, a select sequence and a parallel sequence. In a select sequence, when the select step is error, the whole process is stopped. If the error step has no connection the whole process, the loss is down when we debugging the program without stopping the whole process. Therefore, this thesis shows the efficient method of remote control for select sequence and we confirmed its feasibility through actual example.

Sony has recently launched a remote play service that connects PC and PlayStation4 using the Internet. This service enables the network connection between the external network and PS4 network. After the service released, additional security threats may arise in remote environments with new services. Therefore, those threats should have been analyzed. In this paper, as applying threat modeling to remote play system, threats have been analyzed and identified. After cost-effective and usability analysis, finally, reasonable security measure of each threat has been suggested.

Home network is the connection and communication of several electronic and electrical devices at hone with the integration of several technologies like Ethernet, wireless, phone line and power-line at the residential gateway to the internet. This internet based home network can be accessed from any part of the world through any device by any poison via internet. Since home network is developed for comfortable and safe life of home users, the information flow to/from home network needs to be private. Hence the remote access of the home network must be secured. This paper analyses two secure tunneling methods, voluntary and compulsory for L2TP(Layer Two Tunneling Protocol) based VPN(Virtual Private Network) for secure remote access of the home network.

Today cases of using individual service on community TV are increasing with the advent of smart TV. The traditional way for using individual service like e-mail or SNS on TV is not simple and puts in too much time because it has to type so many text using remote control that is unsuitable for typing. In this paper, interaction using cube remote control is proposed in order to facilitate individual service on TV. It is simple interaction like shaking and tapping instead of a complex interaction method. In addition, it is believed that the proposed simple interaction using cube interaction might be one of great alternatives for using individual service on smart TV.

모바일 시스템의 카메라 용용 어플리케이션은 기본적인 이미지 저장 및 영상 촬영뿐만 아니라 카메라 기반의 증강현실 및 위치 기반 서비스 등 다양한 응용 분야에 활용할 수 있다. 특히, 셀프 활동에 많이 활용되는데, 이때 발생하는 문제점은 셀프 촬영이 힘들다는 것이다. 스마트폰 카메라를 자유롭게 제어하고, 나아가서는 카메라 촬영 및 다양한 이미지 프로세싱을 보조해줄 수 있는 시스템 및 장치가 필요하다. 본 논문에서는 안드로이드 스마트폰 기반의 카메라 제어 모듈과 카메라 제어 모듈을 활용한 이미지 프로세싱 보조 시스템을 구현해보도록 한다. 카메라 제어 모듈은 리모트에서 안드로이드 스마트폰의 카메라 촬영을 제어할 수 있으며, 여러 대의 안드로이드 스마트폰과 연동해서 다양한 각도에서 하나의 피사체에 대한 카메라 촬영이 가능하도록 통신 제어 시스템이다. 이를 활용하면 모바일 카메라 응용 서비스를 좀 더 폭넓게 활용할 수 있을 것이다.

It is difficult to meet the cleanliness requirement of $10^{10}/\textrm{cm}^2$ for the giga level device fabrication with mechanical cleaning techniques like scrubbing which is widely used to remove the particles generated during Chemical Mechanical Polishing (CMP) processes. Therefore, the second cleaning process is needed to remove metallic contaminants which were not completely removed during the mechanical cleaning process. In this paper the experimental results for the removal of the metallic contaminants existing on the wafer surface using remote plasma $H_2$ cleaning and UV/$O_3$ cleaning techniques are reported. In the remote plasma $H_2$ cleaning the efficiency of contaminants removal increases with decreasing the plasma exposure time and increasing the rf-power. Also the optimum process conditions for the removal of K, Fe and Cu impurities which are easily found on the wafer surface after CMP processes are the plasma exposure time of 1min and the rf-power of 100 W. The surface roughness decreased by 30-50 % after remote plasma $H_2$ cleaning. On the other hand, the highest efficiency of K, Fe and Cu impurities removal was achieved for the UV exposure time of 30 sec. The removal mechanism of the metallic contaminants like K, Fe and Cu in the remote plasma $H_2$ and the UV/$O_3$ cleaning processes is as follows: the metal atoms are lifted off by $SiO^*$ when the $SiO^*$is evaporated after the chemical $SiO_2$ formed under the metal atoms reacts with $H^+ \; and\; e^-$ to form $SiO^*$.
