    Abstract: An automotive balanced microphone system (300) includes a microphone (303) located in a vehicle mirror (301) connected in a balanced configuration for eliminating noise. A split resistor network (305) is used for supplying a supply voltage to the balanced microphone (303). The split resistor network (305) allows the microphone (303) to be easily powered while noise induced into the supply lines can easily cancelled at the microphone output for use with an electronic device (309).

    Abstract: A rearview assembly (10) includes a mounting structure (154) for attaching to a vehicle. The mounting structure (154) includes a housing (30) that has a rearview element (40) disposed inside for providing a driver of the vehicle with a view to the rear of the vehicle. The rearview assembly (10) also includes a continuously variable slope delta encoder module (11) in or on the mounting structure (154) configured to generate a feedback signal. The rearview assembly (10) also includes a pre-processing module (12) on or within the mounting structure (154). The pre-processing module (12) is configured to process a source signal and the feedback signal from the continuously variable slope delta encoder module (11), and to provide a pre processed signal to the continuously variable slope delta encoder module (11) based on the value of the source signal and the feedback signal.

    Abstract: 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).

    Abstract: A control system for one or more electrochromic elements used in an outside electrochromic (OEC) mirror used in automobiles or other vehicular applications, to control the glare of both IEC elements used as a rearview mirror (20) as well as the OEC elements (24, 26) used as sideview mirrors (24, 26). An ambient light senor (129) and glare sensor (133) operate to determine a glare level used to control both IEC and OEC electrochromic elements. The drive circuits for the OEC's elements may be controlled so as to account for various factors such as tinted glass characteristics in the vehicle.

    Abstract: An interior rearview mirror assembly (101) for a vehicle includes a mirror housing (106) adapted for attachment to the interior of the vehicle, the mirror housing (106) including a back surface (107) generally facing the front of the vehicle and an opening generally facing the rear of the vehicle. A mirror (108) is disposed in the opening of the mirror housing (106) where a first microphone assembly (108a), second microphone assembly (108b), and third microphones assembly (108c) are positioned in the mirror housing (106) along its rear, bottom, or top surface. Each of the three microphone assemblies (108a, 108b 108c) are arranged in a substantially triangular configuration for reducing unwanted sound in the vehicle from at least one direction. The microphone assemblies may operate using a delay-and-sum beam-former (403, 405) and digital signal processor (DSP) (407) for enhancing the directivity of the microphone array within the vehicle.
