Abstract: A bipolar electrode for use in a lithium-ion battery includes a current collector, an anode having high aspect ratio conductive carbon particles and an anode binder, and a cathode having cathode active particles in a cathode binder. The high aspect ratio conductive carbon particles in the anode are aligned so that a long axis of the high aspect ratio conductive carbon particles is substantially perpendicular to the current collector. The cathode active particles are paramagnetic, diamagnetic, or magnetic and have been magnetically aligned, the cathode further comprises high aspect ratio conductive particles aligned so that a long axis of the high aspect ratio conductive particles is substantially perpendicular to the current collector, or both. The bipolar electrode can be made by subjecting the current collector coated with slurries including the components for the anode and the cathode to a magnetic field while drying.

Abstract: Headrest assemblies and method of use thereof are provided to support a neck of an occupant of a seat. The headrest assemblies include a headrest cushion, a neck support cushion, and one or more extension members coupling the neck support cushion to the headrest cushion. The extension member(s) are configured to be transitioned between a retracted configuration in which the neck support cushion is adjacent to the headrest cushion and a first dimension is defined along a central longitudinal axis of the extension member(s), and an extended configuration in which the neck support cushion is cantilevered from the headrest cushion and a second dimension is defined along the central longitudinal axis of the extension member(s) that is greater than the first dimension. The extension member(s) are configured to releasably lock to secure the neck support cushion in a fixed position at least while in the extended configuration.

Abstract: A vehicle system for a vehicle includes a vehicle processor for storing vehicle data including vehicle location, vehicle event data, and vehicle mode. The vehicle system also includes a server communicatively coupled to the vehicle processor. The server is configured to determine if a transport mode has been selected based on one or more of the vehicle mode or the vehicle location. The server is also configured to determine if a current battery change is above a state-of-charge limitation based on the vehicle event data. Additionally, the server is configured to activate the transport mode if the current battery charge is below the state-of-charge limitation.

Abstract: A method for SLAM-based parking assist includes determining that a host vehicle is entering a corridor adjacent a target parking slot and determining a potential reusability of at least one of a plurality of previously determined training outcome of a training process for the target parking slot. The training outcome includes training identifying data of a potential parking slot. The method further includes receiving identifying data of the target parking slot, identifying which of the plurality of training outcomes is reusable based on the identifying data of the target parking slot to select an identified training outcome, comparing the identifying data of the target parking slot with the identifying data of the potential parking slot of the identified training outcome, and loading the identifying data of the target parking slot into a SLAM-based parking assist.
