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 mounting assembly (800A/800b) include one or more transducers (801) mounted to a printed circuit board (PCB) (805) where a spacer (803) is used having a channel (807) positioned on the PCB (805) for allowing acoustical energy to pass through the channel (807) to a port (809) in the PCB (805). A first cover (811) is positioned over the channel (807)for disrupting the direct encounter with airflow into the channel (807) while a top section (813) having a second cover (815) is further positioned adjacent to the first fabric cover (811) for preventing debris from obstructing the first fabric cover (811).

摘要： An imaging assembly for use in a vehicle is disclosed. The imaging assembly may include an image sensor configured to capture image data and an electro-optic element configured to selectively control a range of wavelengths corresponding to light in a near infrared (NIR) range of light entering the image sensor. The electro-optic element may include a first portion configured to absorb the range of wavelengths entering the image sensor and a second portion configured to absorb the range of wavelengths entering the image sensor in a first state and to transmit the range of wavelengths entering the image sensor in a second state. The second portion may be electrically isolated from the first portion. A controller may be in communication with the image sensor and the electro-optic element. The controller may be operable to switch the second portion between the first state and the second state.

摘要： A non-spatial speech detection system includes a plurality of microphones whose output is supplied to a fixed beamformer. An adaptive beamformer is used for receiving the output of the plurality of microphones and one or more processors are used for processing an output from the fixed beamformer and identifying speech from noise though the use of an algorithm utilizing a covariance matrix.
