  • Publication number: 20240353627
    Abstract: An optical module according to the present invention includes: an optical device including an optical waveguide chip; an optical fiber block bonded to and arranged on an end face of the optical waveguide chip; an optical fiber that has one end optically connected to the optical waveguide chip via the optical fiber block; an optical fiber holding mechanism for holding the other end of the optical fiber; and an optical fiber carrier. The optical fiber is arranged while being curved from the optical fiber carrier toward the optical fiber block in a U-shape, and a wall structure is formed on the surface of the carrier while being adjacent to the optical fiber at, for example, a position on the outer side of the U-shaped curve of the optical fiber position at which the wall structure reduces a normal force of the optical fiber.

  • Patent number: 12110030
    Abstract: A vehicle behavior estimation system includes: a yaw rate sensor that detects a yaw rate of a diagnosis target vehicle; a vehicle speed sensor that detects a vehicle speed of the diagnosis target vehicle; and a processor. The processor acquires a first curvature that is a curvature of a traveling locus of the diagnosis target vehicle based on the yaw rate and the vehicle speed, and performs a driving diagnosis related to steering of the diagnosis target vehicle based on a criterion and a curvature-related value. The criterion defines a relationship between a steering angle-related value that is a value based on a steering angle of a steering wheel of a reference vehicle that is a vehicle different from the diagnosis target vehicle and a behavior of the reference vehicle caused by steering. The curvature-related value is a value based on the first curvature.

  • Publication number: 20240326734
    Abstract: A variable vent mechanism has an air bag having a vent hole, a flap attached to the air bag at a first fix portion and covering the vent hole, a strap extending from a connection end of the flap, fixed to an attachment portion at a second fix portion, and fixing the flap in a closed position where the vent hole is closed, and a device which brings the strap into a free state. A relationship L3/L4 between a maximum length L3 between the first fix portion and the connection end in a first direction connecting the first and second fix portions, and a maximum length L4 of the first fix portion in a second direction orthogonal to the first direction satisfies 0.5?L3/L4?3.0. A length of the flap in the second direction is shorter on the connection end side than on the first fix portion side.
