Publication number: 20240094029Abstract: Techniques for representing a scene or map based on statistical data of captured environmental data are discussed herein. In some cases, the data (such as covariance data, mean data, or the like) may be stored as a multi-resolution voxel space that includes a plurality of semantic layers. In some instances, individual semantic layers may include multiple voxel grids having differing resolutions. Multiple multi-resolution voxel spaces may be merged or aligned to generate combined scenes based on detected voxel covariances at one or more resolutions.Type: ApplicationFiled: May 31, 2022Publication date: March 21, 2024Inventors: Hirotatsu Armstrong, Patrick Blaes, Michael Carsten Bosse, Jeffrey Eric Tolliver

Publication number: 20240055707Abstract: A method of forming a brazed joint is described. The method includes pressing a non-molybdenum component, such as a cross pin of a battery case assembly, against a molybdenum component, such as a terminal pin of the battery case assembly, and applying one or more electrical pulses to form an interface liquid layer between the components that cools to form the brazed joint. At least one of the electrical pulses has a constant voltage over a pulse time. A contact resistance between the components can decrease during the pulse time, and thus, the constant voltage can cause an uncontrolled electrical current of the electrical pulse to increase. The increasing electrical current heats the components sufficiently to form the interface liquid layer having a predetermined thickness that provides a required bend strength. Removal of surface oxides provide consistent mechanical strength for this joint. Other embodiments are also described and claimed.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Shichan Chiang, Christopher Hallmark, Michael Erickson, Kurt Erickson, Nicholas Hamor, Jeffrey Armstrong, Philip Edward Poole, Nathan Messerich

Patent number: 11767016Abstract: A method includes obtaining one or more images of a segment of a route from a camera while a vehicle is moving along the route. The segment of the route includes one or more guide lanes. The method also includes comparing, with one or more computer processors, the one or more images of the segment of the route with a benchmark visual profile of the route based at least in part on an overlay of the one or more images onto the benchmark visual profile or an overlay of the benchmark visual profile onto the one or more images. The one or more processors identify a misaligned segment of the route based on one or more differences between the one or more images and the benchmark visual profile and respond to the identification of the misaligned segment of the route by modifying an operating parameter of the vehicle.Type: GrantFiled: April 27, 2021Date of Patent: September 26, 2023Assignee: Transportation IP Holdings, LLCInventors: Nidhi Naithani, Dattaraj Jagdish Rao, Anju Bind, Sreyashi Dey Chaki, James D.

Patent number: 11735711Abstract: A battery includes a case having a feedthrough port, a feedthrough assembly disposed in the feedthrough port, and a cell stack disposed within the case. The feedthrough port includes an inner conductor and an insulator core separating the inner conductor from the case. The cell stack includes an anode, a cathode, and a separator insulating the anode from the cathode, wherein the anode and cathode are offset from one another. An insulating boot surrounding the cell stack insulates the cell stack from the case. The insulating boot has an opening configured to receive therein the feedthrough assembly, which may include overmolded insulation. The interior surfaces and interior walls of the battery case may be thermal spray-coated with a dielectric material to prevent lithium dendrite formation between cathode and anode surfaces.Type: GrantFiled: February 19, 2021Date of Patent: August 22, 2023Assignee: Pacesetter, Inc.Inventors: Russell Bruch, Joseph Beauvais, Jeffrey Armstrong, Del Charles Brooks, III, Christopher Hallmark, John Duggan
