    摘要： According to one embodiment, a wireless power transmitter wirelessly transmits power to a power receiving apparatus which includes a first resonance circuit and a load circuit. The first resonance circuit includes a power receiving coil and a first capacitor. The wireless power transmitter comprises a second resonance circuit that includes a power transmission coil and a second capacitor and transmits the signal generated by a power supply to the power receiving apparatus, a measuring unit that measures a signal reflection coefficient, and a controller. The controller detects a value of an oscillation frequency of the power supply making the signal reflection coefficient smaller than or equal to a threshold value, calculates an electromagnetic coupling coefficient between the power transmission coil and the power receiving coil, and controls one of the oscillation frequency and a capacitance value of the second capacitor based on the electromagnetic coupling coefficient.

    摘要： A dual wiring system with easy exchangeability of a function unit is provided. A gate device is mounted in a wall surface of a structure, and connected to both of an electric power line and an information line previously installed in the structure. The function unit has at least one of functions for supplying electric power from the electric power line, outputting information from the information line and inputting information into the information line when connected with the gate device. The function unit has a module connector comprised of an electric power connector and an information signal connector, which is detachably connected to a module port of the gate device comprised of an electric power port and an information signal port. To further improve function expandability, an additional function unit can be detachably connected to the function unit.
