Abstract: A charging unit guidance system includes a processor and a memory. The memory includes instructions that upon execution by the processor, cause the processor to receive a sequence of user states associated with a user of a first autonomous vehicle, each user state being one of a walking state and an at-charging-unit state and the sequence of user states being based on a sequence of observed user speeds associated with detected user position data associated with movement of the user from the first autonomous vehicle to a charging unit and at the charging unit, determine a charging unit location of the charging unit based on a correlation between the at-charging-unit states in the sequence of user states and the user position data, and upload the charging unit location associated with the charging unit to an edge computing system, the edge computing system being configured to provide guidance instructions to the charging unit to a second autonomous vehicle based at least in part on the charging unit location.

Abstract: A method of manufacturing a component having a porosity-controlled lithium metal coating includes setting up an aerosol spray apparatus having a material feeder and a confinement conduit in fluid communication therewith. The confinement conduit has an inlet end and a nozzle end. The method also includes setting up a substrate having an exposed surface on a moveable tooling plate and directing the nozzle end at the exposed surface. The method additionally includes loading a lithium metal into the material feeder. The method also includes feeding a high-pressure gas into the inlet end of the confinement conduit to thereby form an aerosol spray of lithium metal. The method further includes moving the tooling plate to regulate a thickness and a pattern of deposition of the lithium metal onto the exposed surface through the nozzle end to thereby generate a porous lithium metal coating on the substrate.

Abstract: A head-up display system of a vehicle visually transmits information to eyes of a first occupant and eyes of a second occupant. The system includes an illumination device emitting first and second display lights having first and second polarizations, respectively. The system includes a windshield and a holographic panel including first and second layers. The display lights emit toward the holographic panel at an entrance angle relative to an axis normal to the holographic panel. The first layer diffracts the first display light having the first polarization in a first exit direction at a first exit angle relative to the axis toward the eyes of the first occupant. The second layer diffracts the second display light having the second polarization in a second exit direction at a second exit angle relative to the axis, and different than the first exit angle, toward the eyes of the second occupant.

Abstract: A method for video streaming includes receiving video streaming data from a wireless camera. The camera is in wireless communication with a vehicle. The method further includes identifying a stable video region in the video streaming data received from the wireless camera, detecting stale video content in the video streaming data based on the stable video region, and in response to detecting the stale video content in the video streaming data, providing a notification to a vehicle occupant, via a display of the vehicle. The notification is indicative that a video streamed in the display of the vehicle is stale. The method described in this paragraph improves video and vehicle technology by identifying stale video content and notifying the vehicle occupant that the video is stale, thereby preventing the vehicle occupant from relying on stale video content.

Abstract: A method for downforce control includes receiving vehicle inputs. The method includes determining a first normal-force request at the front axle and a second normal-force request at the rear axle using the purality of vehicle inputs and a prediction model. The prediction model is a combined state space model that integrates a half-car state space model and an actuator state space model, the half-car state space model is developed using a half-car model, and the actuator state space model is developed using a neural network model. The method further includes determining a first position of the first aerodynamic body relative to the vehicle body and a second position of the second aerodynamic body relative to the vehicle body based on the first normal-force request and the second normal-force request, respectively.

Abstract: A method for controlling charging of a battery to minimize or avoid lithium plating. The method may include charging the battery during with a first charge current having a first charge profile, monitoring charging of the battery with the first charge current, and thereafter charging the battery with a second charge current having a cathode charge profile to prevent a cathode potential of the battery from exceeding a cathode threshold.
