In this paper, A telemetering control system for the HDTV SMPS Aging System is developed. Manual Aging System is usually used to measurement of a produced SMPS. But in this system, the respective operator is arranged and monitoring the test cycle visually. According to an excess of the test time and mistakes of an operator, the reliability makes come to be low. Therefore as using the telemetering control system, it improves a productivity and a reliability of the HDTV SMPS. In the developed system, electrical signal is measured from aging system, and converted into the digital signal. Also the telemetering control system is composed of many units - telemetering control units for collecting the data, data relay units for the digital transmission service, data division for the multichannel realization.

In this paper, A localized electromotion scooter controller for the senior and disabled is developed. Recently, the population which uses the electromotion wheel chair or electromotion scooter is increasing. The reason is that the electromotion wheel chair and electromotion scooter were newly applied in medical treatment grant item. In the whole world, electromotion scooter controller is corning to be produced above a hundred of millions. The products produced are consuming from most Europe and North America. the demand is increasing rapidly in Korea. The electromotion scooter which is sold to domestic is about 40,000 units, and about 70% or more in the products are imported from the foreign nation. Also controller for electromotion scooter uses the foreign nation product. Consequently, as the localized electromotion scooter controller is developed, it will be able to expect an income substitution effect, and apply to the agriculture and leisure mobile equipment parts.
