Abstract: A creel assembly having an outer wall defines an interior space, a plurality of yarn package engagement locations distributed within the interior space, a gantry that is movable secured within the interior space, and at least one processor. The gantry is positioned to selectively engage yarn packages within the interior space. In use, the gantry can selectively access the plurality of yarn package engagement locations. The processor is communicatively coupled to the gantry and receives an input corresponding to a selected action by the gantry. Modular creel systems can be formed from a plurality of the disclosed creel assemblies. Methods of using and assembling the disclosed creel assemblies and modular creel systems are also disclosed.

Abstract: Systems and methods for controlling navigation of an autonomous vehicle are disclosed. The system receives information relating to a geonet that represents a portion of a map area within which the autonomous vehicle is allowed to operate, and a lane-level map comprising a plurality of lane segments corresponding to the map area. For each of the plurality of lane segments, the system identifies a match geonet element from a plurality of geonet elements included in the geonet, determines a match distance between the match geonet element and that lane segment, and selects that lane segment for inclusion in the geonet upon determining that the match distance is less than a threshold distance. An updated lane-level map is generated using one or more lane segments selected for inclusion in the geonet for use by an autonomous vehicle to navigate between an origin location and a destination location within the geonet.

Abstract: A light fixture includes a housing with a channel configured to contain a driver for driving one or more light emitting diodes located outside the channel. The housing includes slots configured to receive and secure a lens. The light fixture further includes a removable channel cover, tabs located along the length of the channel and adjacent to the channel on the housing, and a lens bar having a first flange configured to secure the lens and a second flange configured to be inserted underneath the tabs. The lens bar is secured in place with the second flange underneath the tabs by the channel cover which prevents the lens bar from moving laterally with respect to the tabs. The slots, the first flange, and a flange running the length of the light fixture perpendicular to the slots are configured to cover the edges of the lens when installed.

Abstract: A lighting fixture includes a core member, a first elongated lamp extending outwardly from the core member, a second elongated lamp extending outwardly from the core member, a cap coupled to at least one of the first elongated lamp and the second elongated lamp, and a connector selectively coupling at least one of the first elongated lamp and the second elongated lamp to the core member. A space is defined between the first elongated lamp and the second elongated lamp. The first elongated lamp and the second elongated lamp are positioned such that the space at least one of (a) allows debris to pass therethrough and (b) increases the heat transfer coefficient of the first elongated lamp and the second elongated lamp by at least reducing an overlap between boundary layers, developed from natural convection, associated with the first elongated lamp and the second elongated lamp.
