Abstract: A method for improving intelligibility of speech and/or warning sounds generated in a noisy environment including receiving an audio signal from the noisy environment, segmenting the audio signal into a plurality of frequency bandwidths to provide a plurality of temporal bandwidth limited signals, and providing each temporal bandwidth limited signal to an associated signal path and an associated control path in parallel with the associated signal path. The method also includes filtering the temporal envelope bandwidth signal in each associated control path using a delayless filter to provide an associated control signal, modulating an amplitude of the temporal bandpass signal in each associated signal path using the associated control signal to provide an associated output signal, and combining the associated output signals to provide a combined output signal that improves the intelligibility of the speech and/or warning sounds generated in the noisy environment.

Abstract: In accordance with one embodiment of the present disclosure, a method includes generating a plurality of icons, wherein each icon has a target frequency unique from each other, receiving brain activity data based on an epoch, generating a reference signal based on the epoch, calculating correlation coefficients between the brain activity data and the reference signal, wherein the correlation coefficients are calculated in a window that is within ±0.5 Hz of the target frequencies, including endpoints, determining a confidence score based on the correlation coefficients and the epoch, and determining a selected icon among the plurality of icons based on the correlation coefficients in response to the confidence score surpassing a threshold confidence score.

Abstract: A vehicle system includes a controller programmed to display a plurality of icons on a HUD of the vehicle, receive EEG data from a driver of the vehicle, perform a Fast Fourier Transform of the EEG data to obtain an EEG spectrum, input the EEG spectrum into a trained machine learning model, determine which of the plurality of icons the driver is viewing based on an output of the trained machine learning model, and perform one or more vehicle operations based on the output of the trained machine learning model.

Abstract: In accordance with one embodiment of the present disclosure, a method includes measuring brain activity for a target frequency and a second harmonic frequency based on a default value of display parameters for a plurality of icons, determining whether a strength of the target frequency and the second harmonic frequency are below a threshold level, and modifying one or more display parameters in response to the strength of the target frequency and the second harmonic frequency being below the threshold level.
