  • Patent number: 11837423
    Abstract: An electrical contactor module includes a pair of contactor assemblies each having an input contact, an output contact spaced apart from the input contact, and a linear solenoid disposed proximate the input and output contacts. Each linear solenoid has a housing, a plunger disposed within the housing so as to permit axial displacement of the plunger between an open position in which an end of the plunger is spaced apart from the input and output contacts and a closed position in which the end mechanically contacts and electrically couples the input and output contacts, a spring for biasing the plunger in the open position, and a coil within the housing for urging the plunger from the open position to the closed position along a linear direction. The contactor assemblies are fastened and arranged within an enclosure, with the linear directions for the contactor assemblies pointing in generally opposite directions.

  • Patent number: 11833901
    Abstract: A method includes placing a physical target on a windshield of a vehicle, mounting a fixture inside the vehicle to position a camera array on the fixture within a line of sight of a passenger, capturing images of the physical target using the camera array, and determining a difference between actual and target locations of the physical target in each image. In addition, the method includes controlling the HUD to display a virtual target on the windshield, capturing images of the virtual target using the camera array, and determining a target location of the virtual target in each image based on the difference. Further, the method includes determining an offset between an actual location of the virtual target in each image and the target location of the virtual target in each image, and adjusting the location of an image projected onto the windshield by the HUD based on the offset.

  • Patent number: 11835360
    Abstract: A map database stores data describing a set of connected roads each having one or more lanes, each having one or more lanes. The map database further stores data describing at an avoidance area comprising an area in the map database that an autonomous vehicle (AV) avoids traversing. A routability system determines at least one lane that can be accessed by the AV if the AV traverses the avoidance area, and generates a restored coverage area corresponding to the at least one lane. The restored coverage area corresponds to an area of restored coverage provided by the AV traversing the avoidance area. The routability system computes a score based on the restored coverage area, the score indicating an impact of restoring access by the AV to the avoidance area.

The sensor data can be input into a control model that outputs control signals, in accordance with which the AV operates. A learning cost, i.e., a cost of training or applying the control model, is determined. A performance of the AV during the simulation is evaluated. A simulation cost, i.e., a cost of running the simulation is determined. The control model can be optimized based on the learning cost and the performance of the AV. Settings of the sensors can be optimized based on the simulation cost and the performance of the AV. The optimization of the control model or the settings of the sensors can be done through reinforcement learning.
