  • Patent number: 10803564
    Abstract: Provided is an image processing apparatus capable of assuredly finding a lung field that appears in an image even if a subject image appears in a radiation image in a rotated manner and assuredly performing a contrast adjustment with excellent visibility for the lung field. The image processing apparatus is provided with a sideways determination means 13 configured to determine that the subject image is turned sideways in the original image P0 when a minimum point P of a profile generated by summing or averaging pixel values belonging to each pixel column of the original image P0 for each pixel column is away from the center position of the subject image. The original image P0 determined as being turned sideways by the sideways determination portion 13 is rotated by the image rotation portion 16 and used for searching of the lung field.

  • Publication number: 20200232678
    Abstract: In a gas hot water heater, changes of the signal output of an A/F sensor are calibrated in the atmosphere, in which the A/F sensor detects an oxygen concentration in a combustion tube. The gas supplied via a gas supply pipe is injected, together with in-taken air, into a combustion tube, which is incorporated in a hot water supply tank, via an injection unit. A proportional valve controls a combustion state in the combustion tube based on the detected oxygen concentration to thereby heat water supplied in the hot water supply tank. A purging process is performed to supply air into the combustion tube, at a timing between an extinguishment operation first performed after the ignition the gas mixture in the combustion tube and a re-ignition operation. Changes of signal output characteristics of the A/F sensor are subject to the calibration after the purging process.

  • Patent number: 10685258
    Abstract: According to the present invention, a total value profile to be used for searching a lung field end is generated based on a radiation image. A pacemaker and an annotation reflected in a radiation image are merely reflected darkly in the image, and the existence is not particularly emphasized by edge enhancement. Therefore, the total value profile according to the present invention is not significantly affected by a pacemaker and/or an annotation. Therefore, according to the present invention, there occurs no false recognition regarding the end of the lung field due to a pacemaker and/or an annotation.

  • Publication number: 20200013147
    Abstract: A center of gravity of a chest front image is obtained by a center of gravity calculation using pixel values in the chest front image, and a vicinity pixel position of the center of gravity is set as a center position P of a circular search region having a radius of a predetermined length. The shortest line segment of four line segments obtained by drawing perpendicular lines down from the center position P of an irradiation field to boundary lines of the upper, lower, left and right irradiation fields. The line segment, which is a radius of the circular search region, is rotationally displaced for each predetermined angle ?0, and the profile of the average value for each predetermined angle ? is obtained. From the displacement angle ? of the line segment in which the average value becomes minimum, the orientation of the subject from the head to the abdomen reflected in the chest front image is determined.

  • Patent number: 10495617
    Abstract: A controller as a CO2 sensor reference value calibration apparatus calibrates a reference value of the CO2 sensor in the following manner. Introduction of outside air is started after a person is not detected. A CO2 concentration, which is acquired when a preset first waiting time elapses, is set as a provisional reference value. The carbon dioxide concentration, which is acquired when a preset second waiting time elapses, is compared with the provisional reference value. In a case where a change rate of the carbon dioxide concentration is out of a preset allowable range, the carbon dioxide concentration is acquired when the second waiting time elapses after newly setting the acquired carbon dioxide concentration as the provisional reference value. In a case where the change rate of the carbon dioxide concentration is in the allowable range, the currently set provisional reference value is set as the reference value.

  • Patent number: 10293842
    Abstract: An on-board device is loaded in a moving vehicle and includes a control device configured to control the traveling of the moving vehicle. In the control device, an in-field traveling instructing section determines whether a blockade moving vehicle exists to hinder the traveling of the moving vehicle on a traveling route to an inspection field in a railyard, based on different moving vehicle related data in the railyard when the moving vehicle is an inspection waiting vehicle. A traveling route securing section requests securement of the traveling route to a railyard interface device that controls branching on the traveling route when there is not the blockade moving vehicle on the traveling route. A traveling permission section permits the traveling of the moving vehicle on the secured route based on traveling route state data from the railyard interface device.
