The system may additionally include an interpolation controller configured for collecting a plurality of reflection radar spectrum samples from the reflected signals, identifying an interpolation point between two or more interpolation samples of the samples, calculating an interpolation weight for the each of the interpolation samples, and determining an interpolated spectrum at the interpolation point as a summation of a product of the interpolation weights and the interpolation samples.
Abstract: A battery module includes neighboring first and second battery cells and a heat sink in contact with and configured to absorb thermal energy from each of the battery cells. The module additionally includes a module enclosure surrounded by ambient environment, housing each of the first and second battery cells and the heat sink, and configured to include a thermal conductivity path from the first cell to at least one of the second cell and the heat sink and from the heat sink to the enclosure. The battery module further includes a metal-hydroxide element configured to undergo a chemical decomposition and discharge moisture within the thermal conductivity path in response to thermal energy released by the first cell when the first cell undergoes a thermal runaway event. The metal-hydroxide element thereby controls propagation of the thermal runaway event from the first cell to the second cell.
Abstract: A method that includes obtaining demand data, consumer data, and historical demand data, the demand data represents a demand of consumers for a supply over a past time period in a geographic zone. The demand data includes a recent time segment having unreliable demand information. The consumer data. The method further includes, based on the demand data, estimating a scalar of the demand, and, based on the historical demand data, modeling a standardized model demand profile of mean demand over multiple past time periods. Further, the method includes producing a short-term demand prediction of the consumers of the supply over a portion of a forthcoming time period. The short-term demand prediction is based, at least in part, on the standardized model demand profile, the demand data, and the consumer data.

Abstract: A transmission system for a vehicle includes a first helical pinion gear having a helix angle coupled to a first shaft and configured to receive an input torque. The transmission system includes a second helical pinion gear having a first helix angle coupled to a second shaft and configured to receive the input torque. The second shaft is disposed within the first shaft and rotatable within the first shaft. The transmission system includes a differential assembly having a third helical gear having the first helix angle coupled to the first helical pinion gear, and a fourth helical gear having the helix angle coupled to the second helical pinion gear. The third helical gear and the fourth helical gear are coupled to a differential gear set to drive a first output shaft and a second output shaft associated with the vehicle.
Abstract: A multi-actuator capable vehicle headrest includes a headrest support and a multi-cam release mechanism mounted to the headrest support. The multi-cam release mechanism includes a first cam and a second cam. A headrest shell member is pivotally mounted to the headrest support through the multi-cam release mechanism. An actuator is mounted to the headrest shell member. The actuator includes a first actuator portion operable to disengage the multi-cam release mechanism based on a first input and a second actuator portion operable to disengage the multi-cam release mechanism based on a second input that is distinct from the first input allowing the multi-actuator capable vehicle headrest to transition between a deployed configuration and a folded configuration.

Abstract: Presented are electric machines with optimized stator tooth geometries and multi-gauge stator conductors, methods for making/using such electric machines, and motor vehicles equipped with such electric machines. An electric machine includes a housing, a rotor assembly rotatably attached to the housing, and a stator assembly coaxial with and separated by an airgap from the rotor assembly. The rotor assembly includes one or more magnets mounted to a rotor core. The stator assembly includes a stator core with multiple axially elongated, circumferentially spaced stator slots, multiple radially aligned stator teeth interleaved between and separating the slots, and multiple electromagnetic windings wound through the slots. Each stator tooth has an elongated tooth body with a tooth head at a radial end of a tooth root, which attaches to a cylindrical hub of the stator core. The tooth head has an axial cross-section with a trapezoidal crown integral with a rectangular tip.
Abstract: A height adjustable top mount for adjusting a ride height of a vehicle comprising includes a top plate, a worm wheel, a core, and worm gear. The top plate is configured to mount to a body of the vehicle and movable between a first position and a second position. The worm wheel is received in the top plate and includes an inner wheel surface and an outer wheel surface. The core is received within the worm wheel and helically meshed to the inner wheel surface of the worm wheel. The worm gear is meshed to the outer wheel surface of the worm wheel. Rotation of the worm gear drives rotation of the worm wheel, rotation of the worm wheel simultaneously moves the top plate vertically relative to the core, and movement of the top plate adjusts the ride height of the vehicle in a corresponding direction.
