Abstract: A system and method for controlling a merge vehicle travelling along a highway having a merge lane and a main lane. The method includes receiving merge data about the merge vehicle and a surrounding environment of the merge vehicle. The method includes detecting an intent to perform a merge maneuver by the merge vehicle from the merge lane to the main lane based on the merge data. Further, the method includes generating a graph having a plurality of nodes connected by edges. The plurality of nodes includes a start node set to a current position of the merge vehicle and a goal node located in the main lane after the merge lane has ended. The method includes calculating a three-dimensional (3D) trajectory based on the graph by optimizing edge costs from the start node to the goal node, and controlling the merge vehicle based on the 3D trajectory.

Abstract: A kinetic energy harvesting device implementing a half-wave mechanical motion rectification (HMMR) mechanism is described. The energy harvesting device may include an energy harvesting railroad tie, where the tie includes a tie housing configured to be coupled to at least one rail. The tie housing includes at least one spring and at least one energy harvester. The at least one energy harvester includes a generator having an output shaft, a gearhead, a ball screw or other motion transmission, and a one-way clutch. Under a force of a passing wheel on the at least one rail, the at least one energy harvester is compressed, which causes a rotation of the ball screw or other motion transmission, a rotation of the output shaft, and a transmission of torque to a shaft of the gearhead, driving the generator in a unidirectional rotation to generate electrical power via the one-way clutch.

Abstract: Various embodiments of a smart non-pneumatic tire and methods for generating a mean vibration characteristic of the smart non-pneumatic tire are described. In one embodiment, a method for measuring the mean vibration characteristic includes receiving tire-road contact acceleration data from an accelerometer that is secured near a tire-surface contact region, where the tire-road contact acceleration data includes data captured by the accelerometer over a duration of time while a tread along an outer periphery of a sector of the tire contacts a surface. The method further includes receiving velocity data for the tire and load data for the tire over the duration of time. The method further includes generating a mean vibration characteristic based on the above-mentioned data. The method also includes changing a stiffness of spokes of the tire based on the generated mean vibration characteristic in some cases.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for training and deploying machine-learned communication over multi-input-multi-output (MIMO) channels. One of the methods includes: determining a transmitter and a receiver, at least one of which implements a machine-learning network; determining a MIMO channel model; determining first information; using the transmitter to process the first information and generate first RF signals representing inputs to the MIMO channel model; determining second RF signals representing outputs of the MIMO channel model, each second RF signal representing aggregated reception of the first RF signals altered by transmission through the MIMO channel model; using the receiver to process the second RF signals and generate second information as a reconstruction of the first information; calculating a measure of distance between the second and first information; and updating the machine-learning network based on the measure of distance between the second and first information.

Abstract: Aspects of an efficient compensation network for reducing reactive power in a wireless power transfer (WPT) system are disclosed. The compensation network comprises a series/series (S/S) constant current (CC) source, a reactive power compensation capacitor, and a constant current (CC)-to-constant voltage (CV) network. In an example, the S/S CC source comprises a first capacitor connected in series with a first inductor on a primary side of a transformer and a second inductor on a secondary side of the transformer. The S/S CC source converts an input voltage signal of the WPT system into a constant alternating current (AC) current signal. In an example, the CC-to-CV network comprises at least a third capacitor and a third inductor. The CC-to-CV network converts the constant AC current signal into a constant AC voltage signal.
