Patent number: 11984621Abstract: A battery interconnect may include a desired current capacity, integrated fusible links, and be manufacturable using cost effective techniques. In some embodiments, a battery interconnect includes a busbar and relatively thinner links. A busbar carries larger currents and accordingly its cross-sectional areas are relatively larger to reduce ohmic losses. A link carries a much smaller current, and a fusible link is configured to break the circuit when the current is above a threshold, thus requiring a relatively small cross-sectional area. These sometime disparate length scales are addressed using several techniques such as layering a busbar and a foil sheet and pressing portions of a busbar to form the links. The links can be affixed to a plurality of battery cells to connect the cells in parallel or series.Type: GrantFiled: July 17, 2023Date of Patent: May 14, 2024Assignee: Rivian IP Holdings, LLCInventors: Nathaniel Christopher Wynn, Kyle William Butterfield, Tyler David Collins, Charles Ed Chang

Patent number: 11943539Abstract: An environmental capture system (ECS) captures image data and depth information in a 360-degree scene. The captured image data and depth information can be used to generate a 360-degree scene. The ECS comprises a frame, a drive train mounted to the frame, and an image capture device coupled to the drive train to capture, while pointed in a first direction, a plurality of images at different exposures in a first field of view (FOV) of the 360-degree scene. The ECS further comprises a depth information capture device coupled to the drive train. The depth information capture device and the image capture device are rotated by the drive train about a first, substantially vertical, axis from the first direction to a second direction. The depth information capture device, while being rotated from the first direction to the second direction, captures depth information for a first portion of the 360-degree scene.Type: GrantFiled: May 13, 2022Date of Patent: March 26, 2024Assignee: Matterport, Inc.Inventors: David Alan Gausebeck, Kirk Stromberg, Louis D.
