    摘要： An autobias vehicular microphone system (300) includes a microphone (301) which uses an amplifier (306) for amplifying an output of the microphone. A first feedback path (308) provides an amplifier output signal to the amplifier input for providing amplifier linearity, and a second feedback path (305) is used for providing bias to a voltage reference (303). The voltage reference (303) operates to provide an autobias to the amplifier (306) based upon amplifier load-ing. By holding the bias point to a constant voltage, a constant clip level can be maintained depending on varying load conditions of electronic devices (307, 309, 311) using the microphone (301). Additionally, one or more switches can be used to vary the bias point which can be interpreted to control functionality of the electronic devices (307, 309, 311).

    摘要： A rearview assembly comprising a rearview element, a rearview element support assembly supporting the rearview element and a mount adjacent the housing. The mount is configured to connect the rearview assembly to a windshield. At least one of the rearview element support assembly and the mount comprises a crush bracket having at least two legs adapted to be compressed as a force strikes a front of the rearview element. The crush bracket can include at least one tab contacting a heat emitting component and/or an electrically conductive component of a circuit to provide a heat sink for the heat emitting component or a ground for the electrically conductive component, respectively.

    摘要： A vehicular microphone system (200) for post processing optimization of a microphone signal includes a first transducer (201) and second transducer (203) separated by a predetermined distance within an automotive mirror. A first high pass filter network (205) is connected to the first transducer (201) while a second high pass filter network (207) connected to the second transducer (203). A low frequency shelving filter (209) is used for receiving the output from the second high pass filter (207). A first all pass filter (211) is connected to the low frequency shelving filter (209) and a second all pass filter (213) is used in connection with the first all pass filter (211) for tailoring audio characteristics. A summing amplifier (215) is used for summing the output of the first high pass filter network (201, 205) and the second all pass filter network (203, 207, 209, 211, 213) such that the first transducer (201) and second transducer (203) operate with improved directivity resulting in enhanced signal-to-noise performance in a substantially noisy vehicular environment.

    摘要： A microphone assembly includes one or more transducers (2210) that are positioned in one or more housings. A preprocessing circuit (2215) includes a inverted comb filter (2245) for eliminating predetermined frequencies between harmonics of the human voice in a predetermined frequency range. A processing circuit (2220) coupled to the preprocessing circuit (2215) is used for outputting an electrical signal such that the transducers (2210) used in combination with the processing circuit (2220) very effectively cancels noise. The microphone assembly can be employed in a vehicle accessory such as a vehicular mirror.
