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.

Abstract: A control system (10) for a variable transmittance optical filter assembly (46) includes a controller (48) in communicatively coupled to a pair of load terminals (45), and a memory (49) communicatively coupled to the controller (48) and having encoded thereon statements and instructions executable by the controller (48) to transition the optical filter assembly (46) between operating states when coupled to the pair of load terminals (45). The controller is operable to maintain the optical filter assembly (46) at a certain transmittance value between lower an upper transmittance thresholds in a hold mode by applying a pulse width modulated voltage signal (30) across the load terminals (45).
