    • A rearview mirror assembly is disclosed including a housing adapted to be mounted to the vehicle, a mirror disposed in the housing, at least one electrically powered device disposed in the housing, and a power supply for receiving power from a vehicle power source having a voltage in excess of about 24 V and for supplying power at a voltage of about 5 V or less to the electrically powered device. The electrically powered device and the power supply exhibit an electromagnetic interference level of less than about 41 dB&mgr;V/m for emissions in the frequency range from about 0.4 MHz to about 20 MHz. The mirror is preferably an electrochromic mirror, and the electrically powered device may be a control circuit for the electrochromic mirror.
    • 公开了一种后视镜组件,其包括适于安装到车辆的壳体,设置在壳体中的反射镜,设置在壳体中的至少一个电动设备,以及用于从具有电压的车辆电源接收电力的电源 超过约24V,并且用于向电动设备供电约5V或更低的电压。 对于在约0.4MHz至约20MHz的频率范围内的发射,电力设备和电源对于小于约41dBmuV / m的电磁干扰电平。 反射镜优选为电致变色镜,电动装置可以是用于电致变色镜的控制电路。
