Patent number: 11767010Abstract: A driving assist system executes risk avoidance control for reducing a risk of collision with a target existing ahead of a vehicle. A vehicle state parameter includes imaginary relative position and velocity of the vehicle. A target state parameter includes expected direction and speed of movement the target. A risk value is expressed by a function of an estimated collision speed between the vehicle defined by the vehicle state parameter and the target defined by the target state parameter. The driving assist system sets multiple patterns of the target state parameter and sets a probability of each target state parameter. A partial risk value is the risk value when each target state parameter is used. A final risk value applied to the risk avoidance control is a sum of products of the probability and the partial risk value with respect to the multiple patterns of target state parameter.Type: GrantFiled: February 11, 2021Date of Patent: September 26, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Fumio Sugaya

Patent number: 7048489Abstract: A slide pack container housing a plurality of piled slide packs has a cut-off portion. The cut-off portion has a width slightly larger than the width of a slide contained in each slide pack. As a sucker of a package take-out apparatus draws one of the slide packs from the slide pack container through the cut-off portion, a sealed portion of the slide pack interfering with the edge of the cut-off portion is folded inward so that the slide pack is successfully taken out. The sucker transfers the slide pack to a separated unwrapping apparatus. The sucker releases the slide pack when the front edge of the slide pack is caught between paired rollers of the unwrapping apparatus. After a cutter makes a slit on the slide pack, the paired rollers transfer only a wrapping sheet to separate the wrapping sheet from the slide wrapped therewith.Type: GrantFiled: June 12, 2003Date of Patent: May 23, 2006Assignee: Fuji Photo Film Co., Ltd.Inventors: Fumio Sugaya, Yoichi Endo, Akihiro Komatsu, Tomoyuki Takiue

Patent number: 6642058Abstract: An analysis method using a dry chemical analysis element accurately measures change in optical density indicating the composition of a liquid sample without requiring accurate control of the amount and position of the liquid sample dripped on the dry chemical analysis element.

Concurrently, the one-dimensional or two-dimensional optical reading apparatus measures a length or a spread area of the reacted portion. Physical density or activity of a target component contained in the liquid sample is determined based on an integrated value of the degree of the color reaction and the measured length or the spread area of the reacted portion.Type: GrantFiled: May 14, 2001Date of Patent: November 4, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Fumio Sugaya, Yoichi Endo, Nobuaki Tokiwa, Akihiro Komatsu, Yoshihiro Seto
