The elastic conductive cover comprises a hooking member with an opening that is rotatably connected to the ADSC, cannot be independently removed from the ADSC, and includes an inner surface having at least one extended member with a sealing member that is configured to seal a port of the at least one port.
Abstract: A control loop for scaling cloud-based agents in a cluster includes a controller and a feedback signal. The controller may be a proportional-integral controller, or a proportional-integral-derivative controller. The controller may calculate a control variable based on a target number of idle agents for the cluster. The controller receives a target number of idle agents, as well as a current number of idle agents in a cluster. The controller computes the control variable based on the error between the target and current numbers of idle agents, and an integral of the error over time.

Abstract: A light inspection system positions an autonomous vehicle (AV) in a field of view of a camera such that the camera captures an image of a light of the AV. The light inspection system instructs a camera to capture an image of the light while the light is switched on. The light inspection system receives the captured image, determines a luminance of the light based on the image, and determines to service the light in response to the luminance of the light being below a threshold luminance.

Abstract: The navigation of an AV in an environment may be planned based on a model of a restricted traffic zone in the environment. Information of the environment (e.g., a vector map, information of one or more objects, a temporal sequence of semantic grids, a query grid, etc.) may be input into a neural network. The neural network may include a CNN and a GNN. The map and tracks may be input into the GNN. The temporal sequence of semantic grids or query grid may be input into the CNN. The neural network may output edges of the restricted traffic zone. The neural network may output a grid of points representing locations in the environment and information indicating drivability of each respective point. The neural network may output one or more polylines dividing the environment into regions and information indicating whether the AV can drive to or in each respective region.
Abstract: Tandem charging for electric vehicles (EVs) electrically interconnected with each other. The tandem charging may include determining a plurality of EVs requesting to be charged with electrical power available from a charging station, determining charging parameters for the EVs, scheduling charging of the EVs according to the charging parameters, and/or authorizing a pecuniary charge to billing accounts of the EVs in recompense for the charging.

Abstract: Patterns in lane data and traffic signal data around intersections are used to detect potential errors in map databases and automatically generate data for map databases. Groups of lanes inbound into intersections and/or outbound from intersections can be categorized, and these categories may be used to compare lanes around an intersection, or at multiple intersections along a roadway or in a region. Deviations from expected patterns of these intersection categories may be used to identify errors. Patterns of internal lanes based on external lanes and traffic signal data may be used to automatically generate internal lane data for intersections.
