    摘要: A vehicle rain sensor system for detecting precipitation on an exterior surface of a window (19) including an illumination sensor (36) that is decoupled from the window. The illumination sensor is preferably an imaging array sensor which communicates a signal control (42) which further determines whether rain is present on the window. The control preferably includes an edge detection (44) for detecting edges of precipitation droplets on the window and activating the windshield wipers (22) of the vehicle when the number of edges detected exceeds a predetermined threshold value. The rain sensor system may further include a polarizing filter (62) and an illumination source (55), such that rain sensor system may not only prevent false signals of rain when only fog is present on an interior surface (28) on the window, but also allows the rains sensor system to actually detect fog particles on an interior surface on the window, thereby allowing the control to further be connected to a ventilation blower within the vehicle for the purpose of activating the blower to eliminate the fog.

    摘要: An interior rearview mirror system (10) includes a compass system (18) and a display (20). The compass system (18) is operable to display information indicative of a directional heading of the reflective coating of a mirror reflective element (16) and includes illumination sources (24) positioned behind and generally aligned with corresponding ones of the ports. Each of the illumination sources (24) may be energized to project illumination through a respective one of the ports such that the ports are backlit by the respective illumination sources (24) in order to convey the directional information to the driver of the vehicle. The system may include a microprocessor (119) operable to control each illumination source via a respective wire connected between the microprocessor (119) and each illumination source (24). The compass system (18) may utilize a global positioning system for vehicle direction determination.
