  • Publication number: 20200054284
    Abstract: An internal device (1) is implanted in a living body (300). A control section (6) causes a communication section (5) to wirelessly transmit data corresponding to electroencephalogram signals of the living body (300) which are detected through a group of N (N is 2 or more) electrodes, to an external device (200). When the communication section (5) receives a designation signal designating a group of M electrode(s) (2a), M being smaller than N, the communication section (5) is caused to transmit data corresponding to electroencephalogram signals of the living body (300) which are detected through the group of M electrode(s) (2a), to the external device (200) in real time.

  • Patent number: 10559046
    Abstract: A power supply management system according to an embodiment of the present invention includes a fee setting unit configured to set power fee unit prices (first power fee unit price and second power fee unit price) for each time slot, and a notification unit configured to notify a consumer of information on the set power fee unit prices. The first power fee unit price is a power unit price for a household electrical load, and the second power fee unit price is a power unit price in a case of using a charge/discharge device to charge a vehicle-mounted storage battery. The fee setting unit is configured to set, by predicting a load factor of a transformer, a discount rate of the second power fee unit price to become higher (second power fee unit price to become lower) as the predicted load factor becomes lower. The second power fee unit price is determined on the basis of the first power fee unit price and the discount rate.

  • Patent number: 10362641
    Abstract: A microwave oven includes a waveguide having an E-bend structure with multiple openings disposed on a lateral face of a heating chamber that allow the waveguide to communicate with the heating chamber. The waveguide has a first section for propagating a microwave from a magnetron toward the heating chamber, and a second section having a wide plane that abuts an outer wall of the heating chamber. The openings include at least one circularly-polarized-wave opening for generating a circularly polarized wave. A cross section of the first section orthogonally intersects a tube axis of the first section projects virtually along the tube axis of first section and onto a lateral face of the heating chamber, and the circularly-polarized-wave opening is configured such that its center is located outside the resultant projected region.
