Patent number: 11650596Abstract: A load alignment aid with range finding sensors positioned diagonally on a mounting platform to calculate range, vertical alignment, and horizontal alignment. Each sensor measures a distance (d) from the mounting platform to the load. Where d(1) does not equal d(2) and d(1) does not equal d(3), a misalignment due to tilt or chassis misalignment is detected. The aid further includes a display which may show a graphic representation of the approach to a load and an alert for misalignment notification.Type: GrantFiled: May 31, 2019Date of Patent: May 16, 2023Assignee: Cascade CorporationInventor: Pat McKernan

Patent number: 11644575Abstract: A technique is provided to more easily measure a distance of a target from a ground surface or a ceiling surface. A surveying device has a laser scanner part and a total station in a unitary manner. The surveying device includes a TS functional part, a laser scanner part, and a distance calculator. The TS functional part positions a reflective prism by using laser light. The laser scanner part performs laser scanning of a ground surface along a vertical plane containing the reflective prism and an optical axis for the laser positioning to obtain a laser scanned point cloud. The distance calculator calculates a distance between the ground surface and the reflective prism on the basis of one or multiple points, which are extracted from the laser scanned point cloud and in proximity to a straight line connecting the reflective prism and a specific plane.Type: GrantFiled: January 3, 2019Date of Patent: May 9, 2023Assignee: TOPCON CORPORATIONInventor: Nobuyuki Nishita

Patent number: 11634888Abstract: When an EMV performs an action comprising moving a tool of the EMV through soil or other material, the EMV can measure a current speed of the tool through the material and a current kinematic pressure exerted on the tool by the material. Using the measured current speed and kinematic pressure, the EMV system can use a machine learned model to determine one or more soil parameters of the material. The EMV can then make decisions based on the soil parameters, such as by selecting a tool speed for the EMV based on the determined soil parameters.Type: GrantFiled: May 3, 2022Date of Patent: April 25, 2023Assignee: Built Robotics Inc.Inventors: Gaurav Jitendra Kikani, Noah Austen Ready-Campbell, Andrew Xiao Liang, Joonhyun Kim
