Abstract: An augmented-reality (AR) eyewear display utilizes an optical waveguide having multi-layered optical gratings in a repeating arrangement. The optical gratings include varying depths, slope angles, lengths, and/or widths in order to tune the gratings to provide an improved AR eyewear display. By using the different configurations of two-dimensional or three-dimensional gratings disclosed herein in a waveguide of an AR eyewear display, optical characteristics of the waveguide are optimized to provide, e.g., high resolution and/or contrast, high display uniformity, high input coupling efficiency, and/or high output coupling efficiency. Accordingly, in some embodiments, aspects of the present disclosure enable lower-power AR eyewear displays to produce the same quality of display of a higher-power conventional AR eyewear display waveguide.

Abstract: Safety metrics and/or statistical system assurance of a particular package of autonomy driving software may be substantially measured using data collected from manually driving a vehicle in the real word, simulations of scenarios which may be faced by a vehicle in the real world, simulations executed with actual software and/or hardware on a vehicle, and/or end-to-end testing of a vehicle in a test environment. Safety metrics and performance of AV software and hardware may be further evaluated through vehicle-in-the-loop testing. During each test scenario, a corresponding set of simulated perception data may be injected to the systems of the autonomous vehicle to cause the autonomous vehicle to react and behave as if one or more simulated objects described by the set of simulated perception data were in the environment of the autonomous vehicle. Each test scenario may be triggered to be performed based on, for example, the autonomous vehicle's location within a real-world vehicle testing space.
