Abstract: A mirror assembly includes a housing, an angularly adjustable power pack, wires for supplying power and mirror angle control, an electrochromic mirror subassembly including a heater, and a turn signal device. The components include individual connectors that plug into a multi-prong connector on the bundle of wires, or that piggyback into each other. Optionally, the heater incorporates an internal wire with end connectors for communicating power to opposite sides of the heater, and also includes layers of light-transmitting/diffusing material for diffusing light passing from the turn signal device through the diffusing material. A printed circuit board fits into a pocket in the panel-shaped carrier, and an integral retainer releasably secures the printed circuit board. The power pack is attached to the carrier via a ring of resilient fingers, and a continuous hoop flange prevents distortion of the carrier and in turn of the glass elements in the mirror subassembly.

Abstract: A control system for a plurality of electrochromic elements, for example, used in automobiles, to control the glare of the IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). The drive circuits for the OEC's elements may be customized to account for various factors such as the type of curvature as well as the size, vehicle glass characteristics, such as tinting, operating temperature and shape.
