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.

    Abstract: In at least one embodiment a fault sense circuit includes a current sense device, a voltage sense device, a power sense device, a sub-combination thereof or a combination thereof. The current sense device is positioned to sense a drive current provided to a load by a drive circuit. The voltage sense device is coupled across the current sense device and receives a threshold signal at a first input and provides an output signal on an output whose value is dependent upon whether a sense signal at a second input is above or below the threshold signal. A level of the threshold signal changes in response to a voltage level of a power supply that supplies the drive current to the drive circuit.

    Abstract: A unitary electro-optic window assembly includes a window element. A first substantially transparent substrate defines a first surface, a second surface, and a first peripheral edge. A second substantially transparent substrate defines a third surface, a fourth surface, and a second peripheral edge. The first and second substantially transparent substrates define a cavity there between. An electro-optic medium at least partially fills the cavity and is configured to reduce light transmissivity of the window element. A controller is adjacent to the window element and is in electrical communication therewith. The controller is configured to change a voltage applied to the electro-optic medium to change the light transmissivity of the window element. An interface is in electrical communication with the controller. A transparent dust cover is positioned over the window element, the controller, and the interface.

    Abstract: An autobias vehicular microphone system (300) includes a microphone (301) 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 an voltage reference (303). The voltage reference (303) operates to provide an autobias to the amplifier (306) based upon amplifier loading. Thus, a DC feedback loop works as an average voltage sensing circuit operating to center the amplifier (306) to an operating point near one half its supply voltage. By allowing the bias point to vary, a constant clip level can be maintained depending on varying load conditions of electronic devices (307, 309, 311) using the microphone (301).
