  • Patent number: 9933995
    Abstract: Method and system for displaying images on headphones worn by a user and/or for displaying a status of the user. The headphones include a display screen on an outward-facing surface of the headphones. The display screen can display images related to audio being listened to by the user. The display screen can also display a status of the user, such as “on the phone” or “busy.” The display screen can be a touch screen display, and the user can input commands to the headphones by touching and/or gesturing on the display.

  • Publication number: 20160363992
    Abstract: A wearable device worn on the head of a user determines the head orientation of the user. A tracking application executing on the wearable device determines the orientation of the wearable device relative to a frame of reference. A mobile application executing on a mobile device likewise determines the orientation of the mobile device relative to the frame of reference. The frame of reference may be magnetic north or an inertial reference frame shared between the wearable device and the mobile device. The tracking application estimates the head orientation of the user, relative to the mobile device, based on the relative orientations of the wearable device and the mobile device.

  • Patent number: 9008331
    Abstract: Frequency equalization system substantially equalizes the room frequency responses generated by at least one loudspeaker within a listening area so that the frequency responses in the listening area are substantially constant and flat within a desired frequency range. The frequency equalization system uses multiple microphones to measure the impulse responses of the room and uses the impulse responses to design filters to process the audio signals of one or more subwoofers to achieve an improved bass response that is flat across the relevant frequency range. The system employs an algorithm that is a closed-form, non-iterative, mathematical solution and features very short computation time.

  • Publication number: 20050063554
    Abstract: A system is provided for configuring an audio system for a given space. The system may statistically analyze potential configurations of the audio system to configure the audio system. The potential configurations may include positions of the loudspeakers, numbers of loudspeakers, types of loudspeakers, listening positions, correction factors, filters, or any combination thereof. The statistical analysis may indicate at least one metric of the potential configuration including indicating consistency of predicted transfer functions, flatness of the predicted transfer functions, differences in overall sound pressure level from seat to seat for the predicted transfer functions, efficiency of the predicted transfer functions, or the output of predicted transfer functions.
