Patent number: 11823005Abstract: 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.Type: GrantFiled: March 11, 2022Date of Patent: November 21, 2023Assignee: KEYENCE CORPORATIONInventor: Ikuo Yamada

Patent number: 11072305Abstract: 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.Type: GrantFiled: October 30, 2018Date of Patent: July 27, 2021Assignees: Toyota Jidosha Kabushiki Kaisha, Toyoda Gosei Co., Ltd.Inventors: Yasunobu Yamazaki, Mitsuyoshi Ohno, Ikuo Yamada
