B lock Device with Power Line Communication and Its
Implementation
TAKAYUKI YASHIKI†1 JUNICHI AKITA†1
The downsizing of the computer advanced, there were small device like block that a child played and there weremany studies to perform three dimensions shape modeling by assembling it and came to be done. Whenflexibility of the connection is high and putting a computer on a small housing, To secure a power supply bus andsome data bus is a very important problem. Therefore, in this study, We suggest a block type device using theelectricity excellence communication. We can reduce a physical line by standardize a power supply bus and adata bus, and the downsizing of the device becomes easy. We explain realizing electricity excellence and a device
equipped with it.
