  • Publication number: 20240029453
    Abstract: This paper discloses a careless driving determination apparatus. The careless driving determination apparatus captures a plurality of face images of a driver of a vehicle in a predetermined period using a driver monitor camera. Then, it determines whether each of the plurality of face images shows first status in which the driver wears a wearing object or second status in which the driver does not wear the wearing object, the wearing object covering a part of a face of the driver. Then, it calculates a distribution range of angles of face directions or angles of gaze directions of the driver. Then, it sets a threshold range based on ratio of face images that show the first status and ratio of face images that show the second status. Then, it determines that the driver is in a careless driving state when the distribution range is included in the threshold range.

  • Publication number: 20240003959
    Abstract: In an insulation inspection method for detecting creeping discharge that occurs in a coil in an armature, a predetermined impulse voltage is applied to the coil, and an electrical current value of a current that flows to a current detector that is connected to the coil is detected. The detected electrical current value is analyzed to acquire a relationship between a frequency and an electrical current value spectrum in the detected electrical current value. Based on the acquired relationship, a total sum of electrical current value spectrum areas in a high-frequency band is calculated as a high-frequency spectrum area. The high-frequency band differs from a predetermined low-frequency band in which partial discharge that occurs in a portion of a thin coating of the wire configuring the coil can be detected. Based on a magnitude of the calculated high-frequency spectrum area, creeping discharge that occurs in the coil is detected.
