The FGI is an integral component of the MSC test equipment and is situated in a slot along the ISA bus of the test equipment PC. The main function of the FGI is an interface between the MSC image data via hotlink interface and Frame Grabber. The FGI has two independent receiving channels that allow the board to receive image data arriving. The FGI also includes two transmission channels with hotlink transmitters. Additionally, the FGI is capable of generating digital video test patterns to test the NUC.

This paper propose a control network system based on IEEE1394 for a multi body robot control. The IEEE1394 has the characteristic of high speed(400Mbps), real-time, stability and plug&play. And IEEE1394 also supports freeform daisy chaining, branching and hot plugging, which reduce cabling complexity and make a system simple. Especially, multi host and broad casting support network data sharing method which is suitable for control network for multi body robot. Through experiment, we show that the proposed control network can interface 48 joints (BLDC motors, gears, and encoders) and four 6-axis force/torque sensors with 4Khz communication bandwidth, which is adequate for a multi body robot.

In this paper, we implement a navigation software of a Global Navigation Satellite System (GNSS) receiver based on a commercial purpose GNSS software receiver platform and verify its performance by performing experimental tests for various GNSS signals available in Korea region. The SX3, employed in this paper, is composed of an application program and a Radio Frequency (RF) frontend, and can capture and process multi-constellation and multi-frequency GNSS signals. All the signal processing procedure of SX3 is accessible by the receiver software designer. In particular for an easy research and development, the Application Programing Interface (API) of the SX3 has a flexible architecture to upgrade or change the existing software program, equipped with a real-time monitoring function to monitor all the API executions. Users can easily apply and experiment with the developed algorithms using a form of Dynamic Link Library (DLL) files. Thus, by utilizing this flexible architecture, the cost and effort to develop a GNSS receiver can be greatly reduced.

하나의 브랜드는 다양한 서비스를 각각의 플랫폼에 적용시키기 위한 노력으로 다양한 제품들을 만들어 내고 있다. 그러나 사용자는 이로 인해 파생된 다양한 인터페이스와 네비게이션 방법, 메뉴 구조 등으로 인해 제품의 이용 학습에 불편함을 겪고 있다. 이를 최소화하고 일관성 있는 사용을 위해서 사용 환경 예측성을 높일 수 있는 사용자 인터페이스를 위한 가이드가 필요하다. 즉 이전의 사용 경험을 동일하게 적용하여 새로운 사용 환경을 예측할 수 있는 일관된 정책을 가진 사용자 인터페이스 가이드를 말한다. 이에 본 논문에서는 여러 플랫폼에 적용된 한 기업의 제품군이 일관성을 가지는 사용자 인터페이스 요소를 Family UI라 정의하고 Family UI가 적용된 사례를 분석하여 시사점을 제공하고자 한다.

기존의 헤드업 디스플레이는 작은 허상 크기로 인하여 운전자가 영상 정보를 쉽게 인식할 수 없는 어려움을 가지고 있기 때문에, 본 연구에서는 수평 방향으로 영상을 넓히는 다중 화면 구조와 컴바이너 렌즈를 사용하여 영상 확대와 다채널 윈도우 구조의 헤드업 디스플레이를 연구하였다. 0.47inch 크기의 LCD를 사용하여 투과와 반사 기능의 허상 영상을 사람의 눈에서 3m 위치에 구현하는 기술을 연구하여 근거리와 원거리의 물체에 대한 운전자의 인지 시간을 짧게 하였다. 허상 영상의 콘텐츠로는 스마트 폰을 이용하여 다양한 내비게이션 정보 등을 디스플레이 할 수 있도록 하여 안전과 정보를 동시에 제공할 수 있도록 하였다.

This paper presents a novel approach that describes the first-order (linear elastic) partial interaction analysis of members formed by multi-components based on the Generalised Beam Theory (GBT). The novelty relies on its ability to accurately model the partial interaction between the different components forming the cross-section in both longitudinal and transverse directions as well as to consider the cross-sectional deformability. The GBT deformations modes, that consist of the conventional, extensional and shear modes, are determined from the dynamic analyses of the cross-section represented by a planar frame. The partial interaction is specified at each connection interface between two adjacent elements by means of a shear deformable spring distributed along the length of the member. The ease of use of the model is outlined by an application performed on a multi-component member subjected to an eccentric load. The values calculated with an ABAQUS finite element model are used to validate the proposed method. The results of the numerical applications outline the influence of specifying different rigidities for the interface shear connection and in using different order of polynomials for the shape functions specified in the finite element cross-section analysis.
