  • Publication number: 20210143684
    Abstract: A contactless power feeding apparatus includes a plurality of primary coils mounted on a road and a power feed controller which uses a portion of the primary coils as a power transmitting coil to achieve delivery of electrical power from the power transmitting coil to a secondary coil mounted in a vehicle. The power feed controller uses a selected primary coil that is one of the primary coils other than the power transmitting coil to decrease a leakage of magnetic flux arising from excitation of the power transmitting coil. Instead of the selected primary coil, the secondary coil may be used to reduce the leakage of magnetic flux.

  • Publication number: 20200376382
    Abstract: A non-limiting example game system comprises a processor incorporated in a main body apparatus, and the processor causes a player character to dig the ground based on an operation input of a player, thereby to form a hole. Water is placed in the hole, whereby a water place is formed. A shape of the water place is changed by expanding the hole, and when the water place has a long shape, the water is controlled so as to flow. When the water place is not a long shape, the water does not flow. That is, a river or a pond is formed in a game field based on an operation input of the player. When causing a player character to perform fishing based on an operation input of the player, different processing is executed between the river and the pond.
