Method and apparatus for controlling an electrochromic device |
摘要 |
The invention comprises an apparatus and methodology facilitating an accurate, user-friendly system for controlling the charge state (i.e., color level) of an electrochromic device. The invention provides a two button control methodology implemented as a sequential logic controller or, in another embodiment, a microprocessor-based controller. After initiation via, e.g., an external switch, the invention iteratively modifies and measures a charge level of the electrochromic device until an additional switch activation or until a maximal or minimal charge level is achieved.
