Abstract: A self-powered variable transmittance optical device, such as a smart window or other device, and associated method are provided. The device comprises one or more transparent substrates, with a switching material disposed thereon or therebetween. The switching material may be a hybrid photochromic/electrochromic material capable of transitioning from a first transmittance state to a second transmittance state with application of electricity, and from second state to first state due to another stimulus, such as UV radiation. Electrodes are coupled to the switching material for applying electricity. An electrical system provides for controllable application of the electricity, and may store energy. Energy is provided by an energy-harvesting power source such as a solar cell or other photovoltaic source, or array thereof, or another device for harvesting vibrational or thermal energy. Energy harvesting, energy storage capacity and/or switching material may be configured to provide at least a predetermined level of device operability.

Abstract: 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.

Abstract: An optical filter and control system (40) suitable for a dimmable room window comprises a hybrid photochromic-electrochromic optical filter assembly (46) whose transmittance is variable, a controller (48) coupled to it which controls its transmittance (32) and a memory unit (49) coupled to the controller (48) which stores the statements and instructions to be executed by the controller (48) in order to switch the optical filter assembly (46) between operating states. The controller (48) is adapted to maintain the optical filter assembly (46) in a "hold mode" by supplying a pulse-width-modulated (PWM) voltage signal across it so that its transmittance (32) is held both at a certain average value (which can correspond to an intermediate operating state between the fully dark and fully light states) and at a certain variance; the average value of the transmittance (32) being held between lower (33) and upper (34) transmittance thresholds.
