摘要： A display system may include a light source and a waveguide coupler configured to couple light from the light source. A waveguide coupler may include an in-coupling region and an out-coupling region having a plurality of multiplexed volumetric Bragg gratings. A computer-implemented method may include measuring from different angles, by at least one processor and using an imaging technique, skin hair coverage in a skin surface region of a user. Another computer-implemented method may include identifying and mitigating potentially harmful messages in public forums. A further computer-implemented method may include receiving, by at least one processor, imaging results from at least one imaging device. A system may include a substrate and a transparent conductive material applied to the substrate in a specified pattern that forms an antenna. Various other devices, systems, and methods are also disclosed.
