METHOD AND APPARATUS FOR CONTROLLING AN ELECTROCHROMIC DEVICE |
摘要 |
A method and concomitant apparatus for use in an electrochromic control system in which components causing the charging and discharging of an electrochromic device are subject to drift errors and other errors. In the case of such errors, the actual programming level and the desired programming level as indicated by, e.g., a count value, may diverge. The invention periodically determines the actual programming level of the electrochromic device and responsively adjusts a parameter representative of the desired programming level. |
