  • Patent number: 10695015
    Abstract: The present embodiment relates to a radiation imaging system and the like provided with a solid-state imaging device having a structure enabling reduction of linear noise appearing in an integrated image. The solid-state imaging device comprises: L pieces of imaging pixel region arranged along a direction crossing a moving direction of a relative position of the solid-state imaging device; and L pieces of A/D converter provided corresponding to the L pieces of imaging pixel region. Each imaging pixel region includes pixels arranged two-dimensionally to form an M-row by N-column matrix. Any one of the L pieces of A/D converter executes a dummy A/D conversion once or more times after an A/D conversion of an electric signal from a pixel of an m-th row, before an A/D conversion of an electric signal from a pixel of an (m+1)-th row.

  • Patent number: 9614718
    Abstract: A communication device is connected to an end of a first network of a cascade topology, and also to a second network. This communication device transmits a first list including information of communication devices, in the first network, that are destinations of transmission of frames through the first network, to an opposing communication device, in the second network, located at another end of the first network, and receives, from the opposing communication device, a second list including information of communication devices, in the first network, that are destinations of transmission of frames from the opposing communication device through the first network. The communication device determines in which of the first list and the second list a destination of a frame is included, and when the destination of the frame is included in the second list, transmits the frame to the second network.
