Abstract:
1. An interior rearview mirror system for a vehicle, said interior rearview mirror system comprising: an interior rearview mirror assembly, said interior rearview mirror assembly comprising one of (a) a variable reflectance reflective element having a reflectivity which is variable in accordance with a voltage applied thereto and (b) a prismatic reflective element; said reflective element having a field of view rearward of the vehicle when said interior mirror assembly is attached at a portion of the interior of the vehicle; said interior mirror assembly including at least one pivot element enabling a driver of the vehicle to adjust the rearward field of view of said reflective element to that driver's desired setting; said interior mirror assembly comprising a mirror support; said mirror support comprising a mounting portion for attaching said assembly to the said portion of the interior of the vehicle; said mirror support including said at least one pivot element; said reflective element disposed in a mirror housing; electrical circuitry, said electrical circuitry comprising a microprocessor; said electrical circuitry disposed in said mirror housing behind said reflective element such that adjustment about said at least one pivot element by the driver to set the rearward field view of said reflective element moves said electrical circuitry in tandem with movement of said reflective element; said electrical circuitry comprising a compass sensor; said compass sensor comprising a magneto-responsive sensor selected from the group consisting of a magneto-resistive sensor, a magneto-capacitive sensor, a Hall affect sensor and a magneto-inductive sensor; and wherein said interior rearview mirror assembly comprises a CMOS video microchip.
