A system and method for sub-micron analysis of a chemical composition of a specimen are described. A communication connection is achieved through a dynamic IP between a gateway inside the home and an apparatus outside the home in a smart grid network environment, so a user can easily access in-home services based on a dynamic IP. The image capture unit includes an image processor, an image buffer, an optical unit, an image buffer and an interface module. Consequently, pixel data of each line Oi are produced from pixel data of two lines Ii and Ii1 before conversion. Each EMAC is also communicatively coupled to the BSCU so as to receive braking data therefrom.
