  • Patent number: 10422989
    Abstract: A near-eye-display device includes a pair of fluid-filled lenses. The power of an inner lens of the pair of lenses can be set to position a focal plane for a virtual object from infinity to a predefined distance. The optical power of an outer lens of the pair of lenses is set to cancel out the optical power of the inner lens. A single actuator coupled to a reservoir pumps fluid into or out of the lenses to change their optical power. When the actuator is activated, fluid flows into one of the lenses in a pair and out of the other lens in the pair. The amount of fluid in each lens in a pair of lenses is thereby maintained to cancel out the optical power of the other lens. A single actuator can also be utilized to modify the power of two or more pairs of lenses.

  • Patent number: 10423044
    Abstract: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.
