Publication number: 20230324545Abstract: An object detection device includes: a position detection unit configured to detect a position of an object outside a vehicle based on sensor information obtained at a predetermined cycle by an object detection sensor mounted on the vehicle; and a determination unit configured to determine whether the object is a moving object based on a time-series amount of change in the position of the object detected by the position detection unit. A first threshold on a lower limit side and a second threshold on an upper limit side are set as thresholds for the amount of change in the position of the moving object. The determination unit determines that the object is a moving object when the amount of change in the position is larger than the first threshold and equal to or smaller than the second threshold.Type: ApplicationFiled: March 30, 2023Publication date: October 12, 2023Applicant: AISIN CORPORATIONInventors: Koji NAGASE, Hideaki HIROSE, Eiji ITAMI, Kenichi TAGUCHI

Patent number: 5372167Abstract: A cylindrical housing 6 is secured to the bottom surface of an elevatable filling liquid tank 2, and a liquid injection pipe 16 is mounted on the bottom of the housing 6. An exhaust pipe 18 axially passes through the housing 6 and the liquid injection pipe 16, and is disposed for elevating movement. The exhaust pipe 18 is driven by an elevating mechanism 21. A holder 54 carrying a bottle mouth stuffing 52 is fitted in the housing 6, and is urged down by a spring 61. The bottle mouth stuffing 52 tightly engages the mouth of a vessel which is being raised as carried on a vessel receptacle, and accordingly its position is determined by the height of the vessel. The position of the liquid injection pipe 16 and the exhaust pipe 18 is modified in accordance with the elevation of the tank 2, independently from the bottle mouth stuffing 52. Accordingly, a void which remains in the top of the vessel after the vessel is filled with the liquid is adjusted only in accordance with the elevation of the tank 2.Type: GrantFiled: April 15, 1993Date of Patent: December 13, 1994Assignee: Shibuya Kogyo Co., Ltd.Inventors: Hideaki Hirose, Shigeru Yoshida

Patent number: 4832092Abstract: A weight-operated filling system of rotary type is disclosed which is adapted to detect the weight of a vessel and content thereof by means of Roberval weigher. In such system, the centrifugal force which is applied to the vessel and the content thereof causes a metering error, and accordingly the invention provides a rotation detector which detects the rotation of a rotatable member in which Roberval weigher is mounted. A detection signal from the detector is used to correct for the error to derive a true weight. A filling valve is closed to terminate the filling operation when the true weight reaches a given value.Type: GrantFiled: August 7, 1987Date of Patent: May 23, 1989Assignees: Shibuya Kogya Co., Ltd., Yamato Scale Co., Ltd.Inventors: Hideaki Hirose, Shigeru Yoshida, Toru Kohashi
