An over-power detector for detecting an over-power condition of an electronic apparatus powered by power from an AC power source. The receiver can operate based on pure feed-forward processing and compensate the phase error in real time and without relying on pilot symbols or a PLL circuit coupled to the LO source. The first power storage module and the second power storage module are provided in an engine room of a vehicle. When the lever is pivotally moved to a completely-fitting operating position where the two connector housings are properly fitted together, the detection member can be slid, and the thus slid detection member tells a completely-operated condition of the lever, and also prevents the operating portion of the lever from being operated to be moved toward the cancellation side. This results in an FPGA that is re-programmable on-demand and that is useable in a variety of hardware platforms such as, for example, RAIT. The server transmits the execution schedule and voltage settings to the client with the encoded data stream.
