Abstract: A handsfree system and method to modify at least one microphone output based on a linearized correlation between a modified Speech Intelligibility Index (mSII) and a Mean Opinion Score (MOS). The at least one microphone output signal is compared to predetermined thresholds for the mSII that correspond to a noise condition and the microphone output signal is modified to optimize Speech Intelligibility and Sound Quality for the noise condition.

Abstract: A system and method for estimating secondary path impulse response (IR) for an active noise cancellation (ANC) system to enhance performance of the ANC system in a near-imperceptible manner is provided. An adaptive music interference canceller (AMIC) uses music signals as test signals and ANC error microphones to estimate the secondary path IR between all speakers and microphones. The system validates that the music signals have sufficient audio content to be considered an adequate test signal. Furthermore, the system employs additional signal processing to ensure that a unique IR for all speakers and microphones can be obtained using the audio test signals. New coefficients of the AMIC filter are calculated, in real time, using the music signals and can be copied into the estimated secondary path for the ANC system. A supervisor unit manages enabling and disabling the AMIC as needed for calculating and copying coefficients.

Abstract: The present disclosure relates to systems, devices and methods for contextualizing objects relative to a vehicle horizon. In one embodiment, a method is provided including identifying a vehicle horizon based on vehicle trajectory and roadway data relative to the vehicle position and vehicle trajectory. The vehicle horizon is identified to determine at least one roadway segment. Objects relative to the vehicle may be identified and assigned to a roadway segment. Objects may be contextualized by assigning only objects that are associated with the vehicles horizon. Each object assigned to a roadway segment is assigned based on the vehicle horizon. The method may include monitoring each object assigned to a roadway segment associated with the vehicle horizon. By monitoring assigned objects, objects of little to no consequence to the vehicle can be ignored and computing resources of the vehicle may not be wasted on tracking objects of no interest.

Abstract: A speaker having a support structure having a bracket, and a vibration structure having a bend ring. The bend ring comprises an arc portion and an outer brim connected to the bracket. The outer brim of the bend ring extends downwardly to abut and connect to an outer brim of the top of the bracket, and the outer brim of the bend ring does not exceed the outermost end of the arc portion in the radial direction. The effective vibration area of a speaker is increased by using the above structure, so that the sensitivity of the speaker is improved.
