본 논문에서는 지능형 홈 네트워크 디바이스간의 상호연동 미들웨어 Adaptor를 설계하였다. 홈 네트워크 상호연동 미들웨어 Adaptor는 UPnP, LonWorks, LnCP, HAVi 등 다양한 형태의 미들웨어가 존재하고, 다수의 미들웨어를 연동하기 위해서는 기존 시스템을 수정이 필요하지만, 본 논문에서 설계한 상호연동 미들웨어 Adaptor는 다수의 미들웨어를 기존 시스템에 별도의 수정 없이 연동이 가능하도록 설계하였다. 설계한 상호연동 미들웨어 Adaptor에 대한 성능을 평가하기 위해 다양한 업체에서 생산한 디바이스를 이용하여 실험 장치를 구현하였고, 개발한 상호연동 미들웨어 Adaptor가 내장된 모바일 앱 프로그램을 개발하여 성능을 평가하였다.

Influence of the adaptors on the calibration of $100{\mu}H$ inductance standard was studied as a function of torque, applied when tightening the standard inductor terminal with the adaptor. Two different homemade adaptors of BPO gold-plated brass (BPO-Au) and banana-copper (BN-Cu) were made for the connection between the LCR meter and the inductance standard. The measured inductance (L) of the standard inductor and the contact resistance ($R_C$) between the adaptor and the standard inductor terminal showed exponential decreases against the torque increase from $25cN{\cdot}m$ to $150cN{\cdot}m$. The measured L and the calculated equivalence series resistance ($R_S$) were dependent on the adaptor type as well as on the $R_C$. The results of the adaptor analysis imply that the BPO-Au adaptor with the lower $R_C$ is more suitable for the inductance calibration. The calculated inductance of $99.956{\mu}H$ corrected by subtraction of the adaptor inductance and the contact resistance contributions from the measured value using the BPO-Au adaptor agreed well with the certificate ($99.948{\mu}H$) of the PTB within the measurement uncertainty of $140{\mu}H/H$.

An adaptor is designed for chamber impedance measurement of plasma process. Copper rod, fixed board and compensation circuit are the major components of the adaptor. An adaptor can be to measure chamber impedance on time unless stopping a process and Data to measure can do the database. We can use it to a criteria data for a failure diagnosis. So developed adaptor could be used for diagnosis the plasma process chamber in semiconductor industry.

The numerical simulation on the internal flow characteristics of the adaptor in a two-fluid nozzle has been performed to investigate the effects of carrier air supplying parameters using a commercial code. The four adaptor models with the different positions in the carrier air supplying port were considered at the fixed conditions of urea-water solution and carrier air supplying. As the results from the numerical analysis, the internal pressure of the adaptor was varied with the port position for carrier air supplying, and it shows lower pressure value than the atmospheric pressure. Consequently, the flowrate of urea-water solution issuing from the feeding injector with the adaptor varied up to 30% with the port positions for the carrier air supplying. When the carrier air is supplied from the side from the feeding injector axis and the upper part from the feeding injector tip, the flowrate of urea-water solution issuing from the feeding injector with the adaptor show higher value than other carrier air supplying conditions.

This paper presents a novel transformer with a new plastic magnetic core for switching power supplies. The proposed plastic magnetic core was realized using a simple manufacturing process and it can be easily designed with various shapes, suggesting that the manufacturing cost of a power transformer can be reduced using the proposed plastic magnetic core. The possible application potentials of the proposed transformer a AC/DC adaptor utilizing a transformer with the plastic magnetic core are explored. The developed adaptor, that has a maximum power of 24W, switching frequency of 125kHz, and input voltage of 110/220V, has been successfully implemented. A maximum power conversion efficiency of the experimental converter was measured at 77%, and the output was regulated at 12V within 0.2% tolerance.

This paper presents the design approach and test results of the Q-band precision subminiature coaxial adaptor based on transmission line theory using multi-step impedance and air-holes to increase its cutoff frequency. In order to increase the frequency performance, the adaptor is designed with hooked structure, fixing step, multi-air-holes, and outer conductor. The return loss increments due to the hooked structure and multi air-holes are minimized to 2 dB and 1.5 dB, respectively. A VSWR(Voltage Standing Wave Ratio) of <1.2 is obtained from DC to 40 GHz, while guaranteeing the durability of the adaptor from room-temperature$(25^{\circ}C)$ to $120^{\circ}C$.

Interoperation between heterogeneous simulators employs definition of standard protocols for data exchange and time synchronization among simulators. The High Level Architecture(HLA) is a specification of common services for such interoperation, which is approved as IEEE standard 1516. This paper presents the design and implementation of an interoperable adaptor which supports development of interoperable simulators under the IEEE 1516 HLA/RTI environment. The adaptor, KHLAAdaptor1516, is implemented as a library form which is linked to HLA-compliant simulators. Design of the adaptor employs a protocol conversion method, the model of which is finite state machine. KHLAAdaptor1516 allows developers to separate interoperable adaptors from stand-alone simulators. The interoperable adaptor manages mapping between HLA services and simulation messages for simulator, This separation increases robustness of a federation and reusability of simulators as well as alleviates much effort and time for maintenance.
