  • Patent number: 9888900
    Abstract: A dose measured from region information, X-ray information, and a captured image in a previous imaging operation and a dose of radiation obtained from a DAP meter are saved as pieces of information. A dose used in a first imaging operation is based on the saved pieces of information, and a dose to be used in a second imaging operation is estimated from region information or X-ray information in the second imaging operation. If there is a significant difference between the dose in the first imaging operation and the estimated dose for the second imaging operation, a warning is issued. If an image of a region is captured for testing purposes, a warning is not issued.

  • Patent number: 7418591
    Abstract: A network configuration process establishes, between an access point device and a client terminal, a wireless communication link through a first encrypted communication requiring no authentication process, and sends authentication data from the access point device to the client terminal in a state where the wireless communication link through said first encrypted communication is established. The link through the first encrypted communication is discarded in response to sending of the authentication data. Then, a second link is established through a second encrypted communication that requires an authentication process using the sent authentication data, where the first link is continually discarded.

  • Publication number: 20030194090
    Abstract: Account data by which an access point authenticates a communicating apparatus is stored in a detachable memory device. After the account data stored in the detachable memory device was updated on the communicating apparatus side, when the detachable memory device is attached to the access point, the access point discriminates whether the account data has been updated or not. If it has been updated, the account data stored in a memory of the access point is rewritten to the updated account data. After that, the authentication of the communicating apparatus is made by using the updated account data.
