Abstract: An electronic device may include a first bias lens that transmits world light to an output coupler on a waveguide. The output coupler may transmit the world light while coupling image light out of the waveguide. A second bias lens may transmit the world light and the image light to an eye box. A tint layer may transmit the world light towards the output coupler. The tint layer may be planar and layered onto a planar surface of the first bias lens or another lens, may be separated from the first bias lens by an air gap, may be non-parallel relative to the waveguide, and/or may be curved and separated from the first bias lens and the waveguide by air gaps. When planar, the tint layer may be provided with spacers between substrates or between the tint layer and the waveguide to maximize parallelism.

Abstract: In various embodiments, both very high speed and very high sensitivity hydrogen detection is achieved by controlling water vapor concentration over the catalyst used to convert hydrogen in sample gas (e.g., ambient air) to water vapor, to provide a substantially stable water vapor mixing level at a target mixing ratio. The naturally-occurring water vapor in the sample gas, without further steps, typically would vary over time within a wide range (e.g., due to changing atmospheric conditions). By controlling a level of water vapor over the catalyst to be substantially equal to a target mixing ratio that is not too low as to impair response time, and not too high as to impair sensitivity, both very high speed and very high sensitivity can be provided.
