  • Publication number: 20240382064
    Abstract: An information processing apparatus (2000) detects an abnormal region (30) in each of a plurality of video frames (14) constituting video data (12) in which the inside of a body is captured. The information processing apparatus (2000) outputs output information related to the detected abnormal region (30). Herein, the information processing apparatus (2000) starts outputting of the output information when a detection score based on a proportion of the number of the video frames (14) in which the abnormal region (30) is detected becomes equal to or more than a first threshold value in a state where outputting of the output information is not being performed. Further, the information processing apparatus (2000) ends outputting of the output information when the detection score becomes equal to or less than a second threshold value in a state where outputting of the output information is being performed.

  • Patent number: 11014868
    Abstract: A method for producing acetic acid includes subjecting an acetic acid solution to an acetic anhydride decreasing treatment. The acetic acid solution is present typically in, or downstream from, a distillation column (5) of acetic acid production equipment (X), includes acetic acid in a concentration of 90 mass percent or more, acetic anhydride, and water, and is in such a state that an equilibrium concentration of acetic anhydride is higher than an acetic anhydride concentration. The acetic anhydride decreasing treatment includes at least one of water concentration increasing and temperature lowering so as to bring the acetic acid solution into such a state that the equilibrium concentration of acetic anhydride is lower than the acetic anhydride concentration.

  • Patent number: 10936414
    Abstract: The purpose of the present invention is to provide a display device for a vehicle which is capable of avoiding NAND flash memory data loss. Provided is a display device for a vehicle, comprising: a display unit 6 which displays vehicle information; a NAND flash memory 1 which stores, together with an error correction code, data which is related to the display of the display unit 6; and a control unit (for example, a second control unit 2) which causes the display 6 to display the vehicle information using said data. When a load upon the vehicle is low, such as when a switch key for commencing the driving of the vehicle is off, the control unit (for example, a first control unit 3), as a data loss avoidance process, assesses, with the error correction code, whether an error is present in the data which is recorded in the NAND flash memory 1. If the error is present in the data, the control unit (for example, the first control unit 3) corrects the error with the error correction code.
