Abstract: An optical element is provided that has an outer surface, the optical element including: a coating on the outer surface for causing any fluid thereon to form into fluid droplets; a plurality of independently activated electrodes each having a plurality of interdigitated fingers positioned proximate the outer surface and extending across an area of the outer surface; and a drive circuit for selectively applying signals to the plurality of electrodes. The AC signals applied to electrodes having adjacent fingers each have a phase shift such that fluid droplets are continuously swept in a predetermined direction across the outer surface. The electrode fingers may be arranged with a uniform pitch, where the pitch is the distance between the centers of the electrodes, the pitch being less than or equal to 750 μm??. The electrode fingers may be arranged in a single plane with gaps therebetween.

Abstract: A rearview apparatus for a vehicle includes a first measurement device configured to detect a vehicle orientation. The first measurement device is in connection with a portion of the vehicle that maintains a fixed relationship relative to a body of the vehicle. A second measurement device is configured to detect an apparatus orientation of the rearview apparatus, which is adjustable relative to the body of the vehicle. A controller is in communication with the first measurement device and the second measurement device. The controller is configured to identify an orientation difference between the vehicle orientation and the apparatus orientation.

Abstract: An electro-optic system where an electrical potential is changed and/or regulated to achieve a desired potential applied to an electro-optic medium. The electro-optic system comprises an electro-optic medium disposed in a chamber defined in part by two electrodes. A power source is connected to the two electrodes and thereby operable to apply an electrical potential to the electrochromic medium across the two electrodes. A voltmeter is operable to measure an electrical potential between two points within the chamber. Additionally, a controller is connected to the voltmeter and the power source and is operable to regulate the electrical potential applied by the power source based, at least in part, on the electrical potential measured between the two points within the chamber by the voltmeter.
