Abstract: Provided are a system and methods for a unified framework and tooling for lane boundary annotation, which include obtaining sensor data along a trajectory corresponding to locations of a base map. Features are extracted from the sensor data. The features are input into a trained neural network that outputs overlapping rich feature maps comprising polylines. The overlapping rich feature maps are aggregated according to an aggregation function to obtain raster image. Vectorization is applied to the raster images to extract roadway geometry represented by globally consistent polylines.

Abstract: A process for additive manufacture of an article including conjoined first and second metals, wherein the first metal includes one of steel and titanium and the second metal includes another of the steel and the titanium. The process comprises arranging an interface layer of a third metal on a substrate of the first metal, wherein the third metal is capable of forming an alloy with the first metal and capable of forming an alloy with the second metal. The process further comprises supplying a consumable form of the second metal to a locus of the interface layer and heating the locus of the interface layer in an non-reactive environment. In this process, the heating fuses the consumable form of the second metal to render a fused form of the second metal and joins the fused form of the second metal to the interface layer.

Abstract: An embodiment relates generally to an improved method and apparatus for modulating the amplitude and rotation of the plane of polarization of linearly polarized light for multiple uses but primarily as part of a noninvasive glucose monitoring system. As compared to previous monitoring systems, an embodiment provides faster monitoring while maintaining or even reducing noise and minimizing system complexity. Embodiments described herein address these concerns with a modulation and compensation approach that both uses a single high speed device and also modulation of the lasers.
