  • Publication number: 20250055324
    Abstract: A wireless power transmission system wirelessly transmits power from a power transmission apparatus to a power reception apparatus. The system performs detection processing using a first detection method for detecting an object different from the power reception apparatus. The system determines whether a predetermined condition related to a state of at least either one of the power transmission apparatus and the power reception apparatus is satisfied. Then, the system performs object detection processing using a second detection method, different from the first detection method, according to a result of the determination regarding whether the predetermined condition is satisfied.

  • Patent number: 12207964
    Abstract: A radiation detection apparatus includes a housing having an incident face and a side face, a reflective member accommodated within the housing, the reflective member having a reflective face which reflects radio waves, and an antenna element accommodated within the housing. The side face of the housing includes a conductor region and a transmissive region, the transmissive region having a higher radio wave transmittance than the conductor region. The reflective member is disposed in a position at which a first radio wave, which proceeds directly from the antenna element toward the transmissive region, and a second radio wave, which reaches the reflective face from the antenna element and is reflected toward the transmissive region by the reflective face, strengthen each other.
