Abstract: The present disclosure is directed to a plurality of different software models allowing a processor to perform calculations associated with different sets of criteria using data associated with variables that have a strong correlation with one or more of the different criteria sets. Methods consistent with the present disclosure may use several different sets of software that include instructions associated with the collection and evaluation of data associated with a vehicle and with an automated driving system. Different criteria sets may be associated with a range of operating modes, spectral content of received signals, phases of radar signals, and an angular coverage/field of view of the radar apparatus. Results generated by each of the software models may allow a processor to assign weights to the results generated by the different models to generate a combined result that in turn is used to update an operational mode of the radar apparatus.

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.
