  • Patent number: 11389243
    Abstract: A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part.

  • Patent number: 10916212
    Abstract: A display device (1) includes a display panel (10), a first gate drive circuit (11), a second gate drive circuit (12), a first gate slope formation unit (21), and a second gate slope formation unit (22). A plurality of pixels (3) is arranged in a matrix in the display panel. A plurality of gate lines (GL) for selecting pixel groups arranged along rows (X) is arranged along columns (Y) in the matrix. The first gate drive circuit supplies each gate line with a first gate drive signal from each end of the plurality of gate lines. The second gate drive circuit supplies each gate line with a second gate drive signal from each opposite end of the plurality of gate lines. The first gate slope formation unit forms a gate slope which is a falling slope in the signal waveform of the first gate drive signal. The second gate slope formation unit forms a gate slope of the second gate drive signal independently of the first gate slope formation unit.
