  • Publication number: 20220198168
    Abstract: Even if a size of a read image is large, a code search process can be speeded up to enable immediate output of a decoding result. Each time a predetermined number of lines of image data is taken, a pre-processing circuit executes pre-processing on the image data and calculates a characteristic amount indicating the likelihood of the code for each area in the image data. A processor determines a code candidate area based on the acquired characteristic amount and executes a decoding process of the determined area to generate a decoding result.

  • Patent number: 11203320
    Abstract: An airbag uses a rear surface side when inflated as an occupant protection section. The occupant protection section includes a frontal collision restriction surface, oblique collision restriction surfaces on left and right sides of the frontal collision restriction surface, and restriction recessed portions between the frontal collision restriction surface and each oblique collision restriction surface. A recessed portion tether links a tip end side of a recess of the restriction recessed portions and a front end side of the airbag to each other to the inside thereof, and when inflated, at the time of dividing the region into two in the left-right direction around the vicinity of the attachment center to the storage part, provides a remote side region on a side away from a driver seat and a driver seat side region. The capacity of the remote side region is smaller than the driver seat side region.

  • Patent number: 11072305
    Abstract: There is provided a passenger seat air bag having a portion which is unfolded to a side toward a center side of a vehicle in which a pressure difference in the portion is suppressed. A passenger seat air bag includes a front unfolding portion which is unfolded in front of the passenger seat, and a side unfolding portion which is in communication with the front unfolding portion and which is unfolded to side, of the passenger seat, nearer to a center of the vehicle. A horizontal tether is provided in the side unfolding portion in an arrangement which is approximately horizontal during unfolding. When unfolding gas is injected from the front to the air bag, because the horizontal tether does not block flow of the unfolding gas, pressure us the side unfolding portion is made uniform.

  • Patent number: 10661746
    Abstract: An airbag device for a passenger seat is disclosed. The airbag includes a main section whose rear plane forms a front-collision arresting plane, and a sub section which is disposed on a side of the main section and includes a protruding region protruding farther rearward than the main section. The side plane of the protruding region forms an oblique-collision arresting plane. Between the front-collision- and oblique-collision arresting planes is an arresting recess denting forward. The airbag further internally includes a front-rear tether jointed to the front-collision arresting plane, and a recess-pulling tether jointed to the bottom of the arresting recess. The front-rear tether and recess-pulling tethers share a mounting base by which the tethers are mounted on an airbag case, and bifurcate from the mounting base. The front-rear tether extends from a rear edge of the mounting base, and the recess-pulling tether extends from an edge of the mounting base adjoining the front-rear tether.
