Abstract: In various examples, segmented map creation for autonomous and semi-autonomous systems and applications is described herein. For instance, systems and methods described herein may segment a map into various portions, where the systems and methods then update the map based at least on the segmentation. For instance, based at least on receiving instances of data from machines navigating with an environment associated with the HD map, the instances of data may be associated with various portions of the map. Additionally, metrics associated with the portions of the map may be updated, such as by indicating the numbers of instances of data that are associated with the portions of the map. As such, when a metric associated with a portion of a map is satisfied, such as by reaching a threshold, the portion of the map may be updated without updating one or more other portions of the map.

Abstract: Field-deployable spatial positioning or measurement systems are provided for improved versatility, reliability and performance. The spatial positioning or measurement systems use rotating laser fans or beams for positioning and measuring and include a system integrated field-deployable length standard that uses a reelable tape with positional indents. The systems further include the use of labyrinth seals at interface volumes between rotating laser heads and transmitter assemblies to prevent ingress of contaminants and allow for elimination of the use of rotary seals. Further, new dynamic leveling techniques are provided to plumb positional laser transmitter systems. Still further, strobe beam configurations are provided for improved near/far performance and a vertical mode sensing scheme that allows switching to measuring tall structures when needed.

Abstract: The invention relates to a machining center comprising a pallet changing station in combination with a machining station. The pallet changing station includes a rotating column assembly supporting a platform on which multiple fixtures are supported and moved. A portion of the column assembly defines part of a hydraulic conduit for supplying hydraulic fluid from a fluid source to the fixture for use in clamping parts to the fixture. The integration of a portion of the hydraulic conduit with the rotating column reduces the tendency for the hydraulic conduit to become twisted during rotation of the column or for the various threaded connections of the hydraulic conduit from loosening.
