Currently mobile devices change rapidly our life and they have considerable influences over many parts of our society. If the mobile device is applied to a control system, the usability of the control system is increased with its convenient accessibility and mobility. This paper realizes a motor control system by using a mobile device. The device uses Intel Xscale PXA-250 in which Widows CE is ported. The device is very popular at the applications of mobile devices. Also we consider its application to a mobile robot such as home service robot.

In this paper, we consider a digital protection IED(Intelligent Electric Device) for a distributed power system. The IED can measure various elements for protection and communicate with another devices through network. The protection IED is composed of specific function modules: signal process module which converts analog signal from PT and CT handle algorithm to digital one; communication module for connection with another IEDs; input/output module for user-interfaces. A general purpose DSP board with TMS320C2812 is used in the IED. In order to verify the proposed IED, experimental researches with the power system simulator DOBLE has been carried out for a phase earth fault. The results show an under-voltage relaying algorithm has been realized sucessfully in the hardware system.
