Abstract A power source device for supplying driving power from a main power source disposed on a first region to an electric circuit disposed on a second region movable relative to the first region, includes an energy transmitting device provided on the first region, for wirelessly transmitting energy to the second region. An energy receiving device is provided on the second region, for receiving the energy and converting the received energy into source power for use by the electric circuit. Thus, the source power is supplied non-contact from the first region to the second region, both regions being movable relative to each other. As a consequence, the source power for driving an electric circuit can be wirelessly supplied from the first region to the electric circuit provided on the second region without using a wire harness, a slip ring or the like.
A power source transmitting device for use in a motor vehicle and powered by a stationary power source on the vehicle, said power source transmitting device comprising: energy transmitting means disposed on a first stationary region of the motor vehicle for receiving power from the stationary power source and for wirelessly transmitting energy; and energy receiving means disposed on a second movable region of the motor vehicle for receiving the wirelessly transmitted energy and for converting the received energy into source power; and electric circuit means disposed on the second movable region of the motor vehicle for receiving the source power from said energy receiving means and for facilitating motor vehicle operations.
