Abstract: A lithographic patterning of a resist is performed to create a mandrel over a substrate. A deposition of one or more functional materials on the mandrel is performed. And each functional material has a respective refractive index. A selective removal of the mandrel is performed to create a plurality of grating elements formed from the one or more functional materials. The plurality of grating elements are self-aligned and form a diffraction grating. Each grating element may have a heterogenous refractive index (e.g., substantial normal to and/or parallel to a surface of the substrate). The diffraction grating may be used in a near-eye display.

Abstract: An online system causes a graphical user interface to display at a client device. The graphical user interface includes a story field that displays ephemeral content items which are created within a threshold time period and are automatically removed after the time period. The online system uses a computer learned model to rank the selected ephemeral content items for display. The display of a set of ephemeral content items is associated with a session. The computer learned model is trained with sample sets that use an entire past session that includes a plurality of ephemeral content items. The computer model proposes a ranked order of the content items in the past session. Based on the past user actions performed on the past content items, a normalized discounted cumulative gain is determined for the past session. The computer model is trained to optimize the normalized discounted cumulative gain.

Abstract: A waveguide display is used for presenting media to a user. The waveguide display includes a light source assembly, an output waveguide, and a controller. The light source assembly projects an image light at least along one dimension. The output waveguide includes a waveguide body with two opposite surfaces. The output waveguide includes an input area, an output area, a first diffractive element on the first side, and a second diffractive element on the second side of the output waveguide. The output area is located between the input area and the first and second diffractive elements. The first and second diffractive elements reflect a second portion of the expanded image light back toward the output area for outcoupling to the eyebox. The controller controls the scanning of the light source assembly to form a two-dimensional image.

Abstract: Disclosed herein are techniques for fabricating straight or slanted variable-etch-depth gratings. A photoresist material for fabricating a variable-etch-depth grating in a substrate is sensitive to light with a wavelength shorter than 300 nm and has an etch rate comparable to the etch rate of the substrate. A depth of an exposed portion of a photoresist material layer including the photoresist material correlates with the exposure dose. After exposure using a gray-scale mask and development, the photoresist material layer has a non-uniform thickness. The photoresist material layer with the non-uniform thickness and the underlying substrate are etched using a straight etching or slanted etching process to form the straight or slanted variable-etch-depth grating in the substrate. The variable-etch-depth grating is characterized by a non-uniform depth profile corresponding to the non-uniform thickness of the photoresist material layer before etching.

Abstract: A video effects application executes on a client device having an image capture device and receives video data captured by the image capture device. The video effects application extracts information from the captured video data and stores the extracted information as metadata associated with the captured video data. For example, the video effects application identifies objects in the captured video data or identifies optical flow of the captured video data and stores the identified objects or identified optical flow as metadata associated with the captured video data. The video effects application stores information describing modifications to the captured video data in association with the captured video data. When the captured video data is presented, the captured video data, associated metadata, and information describing the modifications is communicated to a renderer, which uses the metadata to perform the identified modifications to the captured video data when presenting the captured video data.

Abstract: It is determined whether an installed firmware of a device matches a reference firmware for the device. In response to a determination that the installed firmware of the device does not match the reference firmware for the device, different types of content sections of the installed firmware of the device are extracted. At least one of the content sections is identified as a dynamic section. A portion of the installed firmware selected to exclude at least the dynamic section is compared with a corresponding portion of the reference firmware to determine a comparison result. A security action is performed based at least in part on the comparison result.
