  • Publication number: 20240404198
    Abstract: The present disclosure provides a recognition technology to be executed by a processor. The processor, by executing a program stored in a computer-readable non-transitory storage, is configured to recognize, in a scan space, a target moving object that is movable in the scan space by scanning the target moving object using a scanning device mounted on a host moving object; acquire three-dimensional scan data representing a scan point group generated by scanning of the scan space; read, from a storage medium, a three-dimensional dynamic map representing a mapping point group generated by mapping of an object present in the scan space; and cluster the scan point group based on identification information for identifying a state of the scan space in each of multiple three-dimensional voxels into which the scan space is divided in the three-dimensional dynamic map and generate recognition data by recognizing the target moving object.

  • Publication number: 20240308574
    Abstract: In a motor control device for a steer-by-wire steering device, the motor control device having a redundant system consisting of two systems, a first turning current command value is calculated in a first system, and a second turning current command value is calculated in a second system. A third processor outputs the first turning current command value when the two current command values are not divergent and outputs the second turning current command value when the two current command values are divergent. When a determination of a rapid steering operation is made, the third processor outputs the first turning current command value regardless of whether or not the two current command values are divergent.

  • Patent number: 11963668
    Abstract: An endoscope system includes a light source apparatus configured to cause light of a plurality of colors to be emitted at a first/second light amount ratio to generate first/second illumination light, an endoscope configured to generate an image pickup signal, and a processing apparatus including a processor. The processor causes the light source apparatus to emit light while switching light between the first/second illumination light, generates a first image signal from an image pickup signal related to the first illumination light, generates a second image signal from an image pickup signal related to the second illumination light and generates a corrected image signal in which color is enhanced based on the first and the second image signals. The second illumination light is light obtained by adjusting the second light amount ratio so that the second image signal related to a reference portion substantially indicates achromatic color.

  • Patent number: 11324396
    Abstract: In a light source apparatus for endoscope, when a light-emission amount of a second light source is less than or equal to a predetermined light-emission amount, a light source control circuit performs a first light-emission amount control of changing the light-emission amounts of the first to third light sources so as to allow a color balance to be maintained at a predetermined color balance. When the light-emission amount of the second light source is greater than the predetermined light-emission amount, the light source control circuit performs a second light-emission amount control of changing the light-emission amount of the third light source by a method different from the first light-emission amount control while changing the light-emission amounts of the first and second light sources by the same method as the first light-emission amount control so as to allow the color balance to be different from the predetermined color balance.

  • Patent number: 10828159
    Abstract: A method of repairing an aortic valve includes, in a following order: an aortic wall incision step; an aortic valve forming step; and an aortic wall suturing step. In the aortic wall incision step, an aortic wall is cut so as to expose an aortic valve side in the inside of an aortic duct to an open atmosphere. In the aortic valve forming step, the aortic valve is formed by restricting a distance between commissures disposed adjacently to each other by placing a thread between the plurality of commissures disposed adjacently to each other. In the aortic wall suturing step, the aortic wall cut in the aortic wall incision step is sutured so as to close the aortic wall.
