Abstract: A relay device 100 of the present invention comprises a receiver 101 for receiving data sent from a first communication device 10, 100 using first communication scheme, a first transmitter 104 for sending the data to a second communication device 11, 100 using the first communication scheme, and a second transmitter 105 for sending the data to a third communication device 12 using second communication scheme simultaneously or continuously with that the first transmitter sends the data, a communication distance of the second communication scheme being shorter than the first communication scheme.

Abstract: A communication terminal device 100 comprises a first power generator 101, a second power generator 102 whose power generation principle is different from the first power generator, a sensor 103 for sensing information, a first communication unit 104 for sending the information using electric power supplied from the first power generator, a second communication unit 105 for sending the information using electric power supplied from the second power generator, the second communication unit uses a communication scheme different from the first communication unit.

Abstract: A power receiving coil and a measuring coil are in a power receiving device. The measuring coil is inductively coupled to the power receiving coil. Concentric turns of a wire in the measuring coil are around a common axis. Also around the common axis are concentric turns of a wire in the power receiving coil. At least one of the concentric turns of the wire in the measuring coil is closer to the common axis than each of the concentric turns of the wire in the power receiving coil. A power feeding device receives a control signal from the power receiving device. The control signal instructs the power feeding device to adjust a power level of an electromagnetic wave emission.
