摘要： An eyewear control system for a variable transmittance optical filter assembly configurable to cover at least a portion of a lens of an eyewear device. The eyewear control system includes a controller communicatively coupled to a pair of load terminals. The eyewear control system also includes a light sensor communicatively coupled to the controller to provide a detector output signal, the light sensor being positioned to receive sunlight transmitted through the optical filter assembly and towards an eye of a person wearing the eyewear device, the detector output signal being set in dependence on an amount of sunlight received by the light sensor. The eyewear control system also includes a memory communicatively coupled to the controller and having encoded thereon computer program code executable by the controller to transition the optical filter assembly between operating states when coupled to the pair of load terminals. The controller is operable to vary a voltage across the load terminals in dependence on the detector output signal to vary an amount of sunlight transmitted to the eye by the optical filter assembly.

摘要： A control system for a variable transmittance optical filter assembly includes a controller in communicatively coupled to a pair of load terminals, and a memory communicatively coupled to the controller and having encoded thereon statements and instructions executable by the controller to transition the optical filter assembly between operating states when coupled to the pair of load terminals. The controller is operable to perform any one or more of: allowing the optical filter assembly to transition to a dark state by shorting the load terminals together, maintaining the optical filter assembly in a hold mode by applying a pulse width modulated voltage signal across the load terminals, and transitioning the optical filter assembly between operative states by applying a voltage signal having voltage pulses of opposite polarities to the load terminals.

摘要： A layered structure for a variable transmittance optical filter includes a transparent conductive electrode and a substrate layer. The transparent conductive electrode includes a charge injection layer that has one or more of gold, molybdenum, palladium, reduced graphene oxide, amorphous indium gallium zinc oxide (a-IGZO), platinum, nickel, ruthenium, rhodium, asmium, selenium, tellurium, graphene, and carbon nanotubes. The substrate layer includes a transparent substrate and is positioned relative to the transparent conductive electrode such that light passing through the transparent conductive electrode passes through the substrate layer.
