Abstract: A collision warning system notifies an occupant of a vehicle about a predicted collision between the vehicle and an object moving relative to the vehicle. The system includes an object input device, a vehicle input device, and a road detection module for generating a road signal associated with a road geometry that is visible through the windshield and located within a field of view of the occupant. The system further includes an ARHUD for generating multiple images upon the windshield and overlaid onto the road geometry. The system further includes a computer including a processor and a non-transitory computer readable storage medium storing instructions. The processor is programmed to determine a predicted collision between the object and the vehicle at a predicted time. The processor is further programmed to generate an actuation signal for actuating the ARHUD to generate the images upon the windshield and overlaid onto the road geometry.
Abstract: An infotainment system for a vehicle selects and plays recordings based on a current emotion of a user in response to receiving a user-generated query. The user-generated query includes one or more words indicating a current state of mind of the user. The infotainment system includes one or more controllers in electronic communication with one or more recording databases that store a plurality of content clusters that each describe a specific recording. The one or more controllers execute instructions to select a recording described by a selected content cluster, where the recording reflects the current emotion of a user.
Abstract: A method for forming a prelithiated, layered anode material includes contacting an ionic compound and a lithium precursor in an environment having a temperature ranging from about 200° C. to about 900° C. The ionic compound is a three-dimensional layered material represented by MX2, where M is one of calcium (Ca) and magnesium (Mg) and X is one of silicon (Si), germanium (Ge), and boron (B). The lithium precursor is selected from the group consisting of: LiH, LiC, LiOH, LiCl, and combinations thereof. The contacting of the ionic compound and the lithium precursor in the environment causes removal of cations from the ionic compound to create openings in interlayer spaces or voids in the three-dimensional layered material thereby defining a two-dimensional layered material and also causes introduction of lithium ions from the lithium precursor into the interlayer spaces or voids to form the prelithiated, layered anode material.

Abstract: A method includes obtaining an initial point cloud for each of two or more radar systems that share a common field of view. Each initial point cloud results from processing reflected energy at each of the two or more radar systems. Each point of the initial point cloud indicates one or more hypotheses for a range, a Doppler, and a direction of arrival (DOA) to an object that resulted in the reflected energy. A point cloud, obtained from the initial point cloud, has a same number of hypotheses for the range, the Doppler, and the DOA. Resolving ambiguity in the common field of view is based on the point clouds to obtain resolved and unresolved points in the common field of view. A radar image obtained from each of the two or more radar systems is used to control an aspect of operation of a vehicle.

Abstract: A system in a vehicle includes a radar system with a uniform linear array (ULA) of antenna elements and a uniform rectangular array (URA) of antenna elements to receive the reflected signals resulting from the emitted radio frequency energy. The ULA is arranged perpendicular to the URA. Processing circuitry estimates one or more elevation angles using the reflected signals received by the ULA of antenna elements and estimates an azimuth angle corresponding to each of the one or more elevation angles using the one or more elevation angles and the reflected signals received by the URA of antenna elements. Each of the one or more elevation angles and the corresponding one of the azimuth angles is referred to as an angle of arrival (AOA) of the reflected signals from an object. Control of an operation of the vehicle is based on each AOA of each object.

Abstract: A method for extracting lithium from lithium-based materials to be recycled using an electrochemical reactor includes applying a voltage to a current collector at least partially disposed in an electrolyte carried by the electrochemical reactor, where the lithium-based materials including lithium to be recovered is disposed in the electrolyte and lithium ions move from the lithium-based material towards the current collector upon application of the voltage. In certain variations, the method may also include, prior to the application of the voltage, applying a current to the current collector.

Abstract: Systems and methods of alerting an occupant of a vehicle to an obstacle to a side of the vehicle. The systems and methods include receiving turn indicating data from at least one vehicle system, receiving perception data from a perception system of the vehicle, predicting a vehicle turn based on the turn predicting data, generating an obstacle alert, which is output through an output device of the vehicle, when an obstacle is detected within a first sized detection zone or a second sized detection zone using the perception data, and switching from using the first sized detection zone to using the second sized detection zone for generating the obstacle alert in response to predicting the vehicle turn. The second sized detection zone is extended as compared to the first sized detection zone.
