  • Patent number: 11926227
    Abstract: In a moving-object power supply system, a control unit selects, as a power transmission segment, one of segments included in at least one power transmission section. The control unit supplies, through a power supply circuit, power to the power transmission segment to thereby generate a magnetic field through a power transmission coil of the power transmission segment. The control unit determines, based on an ascertained first electrical characteristic of the power transmission segment and an ascertained second electrical characteristic of at least one power non-transmission segment, whether there is a malfunction in each of the power transmission segment and the at least one power non-transmission segment.

  • Publication number: 20220020457
    Abstract: To specify, collect, and manage data that matches a usage purpose of a user with high efficiency among enormous medical data. In a case where prescribed medical data is data worthy of evaluation for a user who manipulates a user terminal, a communication unit receives an evaluation result. A database generation unit selectively reads the medical data the evaluation result of which has been received by the communication unit among the medical data accumulated in a medical information storage, and stores the medical data in the storage unit. This processing is repeated every time when an evaluation result is received to generate a database.

  • Patent number: 10760839
    Abstract: In an indoor unit of an air-conditioning apparatus, an air inlet for room air is provided at a position lower than a height position of a drain pan. A partition plate is provided to partition a space below a height position of the drain pan in a housing. A pipe connecting portion connected to a refrigerant pipe of an outdoor unit is provided in one part of the partitioned space and a heat exchanger and a fan are placed in the other part of the partitioned space. At least one communicating path is formed in the partition plate to communicate the two parts of the partitioned space with each other. The indoor unit can include a controller for activating a fan when leakage of refrigerant is detected or for closing the communicating path when leakage of refrigerant is detected.

  • Patent number: 10274219
    Abstract: When a controller determines that a leakage of refrigerant occurs, the controller executes a control of rotating an air-sending fan at high rotation speed. After the control, the controller executes a control of stopping rotation of the air-sending fan or reducing a rotation speed of the air-sending fan in accordance with a result of detection by a first refrigerant sensor provided in a lower portion of a heat exchanger chamber. Thus, the air-sending fan is prevented from continuing the rotation at high rotation speed. Therefore, an indoor unit for an air-conditioning apparatus is excellent in safety and is capable of avoiding feeling of discomfort of a user due to the high-speed rotation of the air-sending fan.
