A method for electrically controlling a functional element with electrically controllable optical properties enclosed in a glazing unit includes controlling the optical properties by a control unit connected to two transparent flat electrodes of the functional element, and applying a voltage by the control unit between the flat electrodes and the polarity of the voltage is periodically changed. The voltage has a trapezoidal profile and by the control unit an increasing electrical voltage is applied for charging the functional element, the electrical voltage increasing to a first peak value, the electrical voltage is reduced from the first peak value to a final voltage for discharging the functional element, the functional element is charged with the increasing electrical voltage with reversed polarity, wherein the electrical voltage increases to a second peak value, the electrical voltage is reduced from the second peak value to the final voltage for discharging the functional element.

A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures images of the face of a driver or other passenger and, based on the captured images, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from striking the eyes of the driver, while leaving the remainder of the visor transparent. The visor system advantageously predicts future positions of the head or eyes of the driver when the driver’s head is in motion. Based on the predictions, the optical state of the visor is updated proactively to anticipate future movements of head of the driver. In this way, some of the negative effects of measurement and processing latencies are mitigated when responding to rapid head motions.

The visor system advantageously detects certain combinations of facial expression and head gestures from which an error or issue with the operation of the visor system can be inferred. In response to such designated combinations of head gestures and facial expressions, the visor system adapts one or more operating or calibration parameters of the visor system to provide more accurate updates to the optical state of the visor.
