摘要： A communication device includes a master station, a ring-type transmission line whose start point and end point are connected to the master station, and a plurality of slave stations connected to the ring-type transmission line in parallel. The master station transmits a signal and feeds electric power from both of the start point and the end point of the ring-type transmission line. Each of the slave stations includes an impedance variable element connected to the ring-type transmission line in parallel, and values are set to the impedance variable elements in accordance with the connection positions of the slave stations.

摘要： A transient increase or decrease of power supplied to a reconfiguration circuit to be a logic circuit whose circuit configuration can be changed is reduced. An autonomous traveling control ECU 201 has a reconfiguration circuit 209, a main power supply circuit 211, an auxiliary current source circuit 213, and a function control unit 207. The reconfiguration circuit 209 is a reconfigurable logic circuit. The main power supply circuit 211 supplies a power supply voltage to the reconfiguration circuit 209. The auxiliary current source circuit 213 increases or decreases a current supplied from the main power supply circuit 211 to the reconfiguration circuit 209. The function control unit 207 determines an operation mode of the reconfiguration circuit 209 on the basis of a mode determination signal input from the outside and indicating a traveling mode of a vehicle, and controls a reconfiguration of the reconfiguration circuit 209 on the basis of a determination result. The auxiliary current source circuit 213 increases or decreases the current supplied to the reconfiguration circuit 209 in accordance with a load variation of the reconfiguration circuit 209, on the basis of an auxiliary current control signal for giving an instruction on an increase or decrease of the current supplied to the reconfiguration circuit 209.

摘要： A load drive system for driving a load supplied with power from a power line includes a control unit which controls switching between the power line and the load and a communication unit which communicates using voltage and current of the power line. When performing the switching, the control unit controls, based on a width of a transition period of the power-line current, the transition period being attributable to the switching, timing of the switching so as to move the transition period away from a center of a period corresponding to a symbol communicated by the communication unit.
