  • Patent number: 11381804
    Abstract: An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.

  • Patent number: 11360385
    Abstract: Methods and systems for manufacturing an optical waveguide include depositing an adhesion promoting layer on a substrate. Multiple curable resist droplets are dispensed on the adhesion promoting layer. The adhesion promoting layer is disposed between and contacts the substrate and the curable resist droplets. The curable resist droplets define an optical eyepiece layer such that a zero residual layer thickness (RLT) region of the optical eyepiece layer is free of the curable resist droplets. The optical eyepiece layer is incised from the substrate to form the optical waveguide.

  • Publication number: 20220179039
    Abstract: This document describes facia, including parts of vehicles, for supporting an ultra-wide radar field-of-view, for example, in automotive contexts. The facia is configured as a radome for supporting an ultra-wide field-of-view with an antenna despite the facia obstructing a field of view. The facia has one exterior surface or interior surface this is a mostly smooth or has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and increase light transmission through the facia. The other of the exterior or interior surface, has a pattern of hemispherical indentations or domes that are configured to reduce reflections off that surface and further increase light transmission through the facia.

  • Publication number: 20220113792
    Abstract: Techniques are disclosed for performing localization of a handheld device with respect to a wearable device. At least one sensor mounted to the handheld device, such as an inertial measurement unit (IMU), may obtain handheld data indicative of movement of the handheld device with respect to the world. An imaging device mounted to either the handheld device or the wearable device may capture a fiducial image containing a number of fiducials affixed to the other device. The number of fiducials contained in the image are determined. Based on the number of fiducials, at least one of a position and an orientation of the handheld device with respect to the wearable device are updated based on the image and the handheld data in accordance with a first operating state, a second operating state, or a third operating state.

The waveguide substrate can include an input coupler grating (ICG), an orthogonal pupil expander (OPE) grating, a spreader grating, and an exit pupil expander (EPE) grating. The ICG can couple at least one input light beam into at least a first guided light beam that propagates inside the waveguide substrate. The OPE grating can divide the first guided light beam into a plurality of parallel, spaced-apart light beams. The spreader grating can receive the light beams from the OPE grating and spread their distribution. The spreader grating can include diffractive features oriented at approximately 90° to diffractive features of the OPE grating. The EPE grating can re-direct the light beams from the first OPE grating and the first spreader grating such that they exit the waveguide substrate.

    Abstract: A secure data fabric (SDF) can include a security platform for sharing data, access and discovery of data, and audit traceability, across disparate data stores and networks. A SDF can leverage blockchain with attribute-based access control (ABAC). A SDF platform can include an immutable data storage medium, a data sharing node, a central processing unit, and memory having software, which can be configured to implement a blockchain and an ABAC module. The immutable data storage medium can be part of a network. The immutable data storage medium can be immutable off-chain data storage for the SDF, and a multi-layered ABAC security policy can be implemented for the SDF. The SDF can have a cross-domain topology model. A multi-party workflow for account keys and digital signatures management can be further implemented.

  • Patent number: 11199719
    Abstract: Methods and systems for qualifying a multi-layered optical stack include providing the multi-layered optical stack including a first optical layer and a second optical layer. The first optical layer includes a first pair of fiducial marks and the second optical layer includes a second pair of fiducial marks Each of the first pair are spaced laterally from each of the second pair such that the first pair and the second pair are visible through the optical stack. A first angle defined between a first reference line connecting the first pair and a global reference line is determined. A second angle defined between a second reference line connecting the second pair and the global reference line is determined. The multi-layered optical stack is qualified for use in the optical projection system based on whether a difference between the first angle and the second angle is less than a predetermined threshold.

  • Publication number: 20210311298
    Abstract: Embodiments of the present disclosure are directed to an optical device, such as an eyepiece, including multiple layers of waveguides. The optical device can include an edge sealant for reducing light contamination, a lamination darn to restrict the wicking of the edge sealant between layers of the optical device, and venting gap (s) in the sealant and darn to allow air flow between the exterior and interior of the eyepiece. The gap(s) allow outgassing from the interior of the eyepiece of unreacted polymer and/or accumulated moisture, to prevent defect accumulation caused by chemical reaction of outgassed chemicals with the (e.g., ionic, acidic, etc.) surface of the eyepiece layers. The gap(s) also prevent pressure differences which may physically deform the eyepiece over time.
