  • Patent number: 8682005
    Abstract: 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.

  • Patent number: 8224012
    Abstract: A microphone assembly includes one or more transducers positioned in a housing. Circuitry is coupled to the transducer for outputting an electrical signal such that the microphone has a main lobe directed forwardly and attenuates signals originating from the sides and/or rear. The transducers can advantageously include multiple transducers, which, with the circuit, produce a desired sensitivity pattern. The microphone assembly can be employed in a vehicle accessory.

  • Patent number: 7825600
    Abstract: A system and method of automatically controlling exterior vehicle lights includes an image sensor and a controller to generate control signals. The control signals are derived based on information obtained from the image sensor as well as other detected parameters pertaining to the detected light source(s), the vehicle having the inventive control system, and the ambient environment. The control circuit may simply turn certain exterior lights on or off, or change the brightness, aim, focus, etc. to produce various beam patterns that maximize the illuminated area in front of the vehicle without causing excessive glare in the eyes of other drivers.
