US Patent 12024948 Systems and methods for controlling an electrostatic shutter

Disclosed herein is an electrostatic shutter system including an electrostatic shutter configured to be selectively raised and lowered based on a voltage applied to the electrostatic shutter, at least one sensor system configured to detect a position of the electrostatic shutter, and a controller communicatively coupled to the electrostatic shutter and the at least one sensor system. The controller is configured to apply an initial voltage to the electrostatic shutter to lower the electrostatic shutter, receive an output signal from the at least one sensor indicating the electrostatic shutter has reached a predetermined position, and based on the received output signal from the at least one sensor, apply an updated voltage to the electrostatic shutter to hold the shutter at the predetermined position.
