Abstract: A hands-free intercom may include a user-tracking sensor, a directional microphone, a directional sound emitter, a display device, and/or a communication interface. The user-tracking sensor may determine a location of a user so the directional microphone can measure vocal emissions by the user and the directional sound emitter can deliver audio to the user. The hands-free intercom may provide privacy to the user. The hands-free intercom may prevent an eavesdropper from hearing the user's vocal emissions, for example, by canceling the vocal emissions at the eavesdropper's ear. The directional sound emitter may deliver out-of-phase sound to cancel the vocal emissions. The hands-free intercom may also, or instead, cancel ambient noise at the user's ear. The hands-free intercom may measure or predict a filtration of the sound to be canceled and compensate for the filtration when canceling the sound.

Abstract: Technologies pertaining to calibration of filters of an audio system are described herein. A mobile computing device is configured to compute values for respective filters, such as equalizer filters, and transmit the values to a receiver device in the audio system. The receiver device causes audio to be emitted from a speaker based upon the values for the filters.

Abstract: The present disclosure provides systems and methods for using compressed sensing for imaging an object for use in combination with an entertainment or infotainment device. For example, the system may utilize a few—(e.g., 1, 2, 3 . . . ) pixel imaging sensor to obtain coarse image data from each of a plurality of subregions of a region of interest. Compressed sensing techniques may then be used to estimate a higher resolution image of the region of interest using the coarse image data from the plurality of subregions.

Abstract: Technologies pertaining to provision of customized audio to each listener in a plurality of listeners are described herein. A sensor outputs data that is indicative of locations of multiple listeners in an environment. The data is processed to determine locations and orientations of the respective heads of the multiple listener in the environment. Based on the locations and orientations of heads of the listeners in the environment, for each listener, respective customized audio signals are generated. The customized audio signals are transmitted to respective beamforming transducers. The beamforming transducers directionally output customized beams for the first listener and the second listener based upon the customized audio signals and locations of the heads of the listeners.

Abstract: The present disclosure provides systems and methods for using two imaging modalities for imaging an object at two different resolutions. For example, the system may utilize a first modality (e.g., ultrasound or electromagnetic radiation) to generate image data at a first resolution. The system may then utilize the other modality to generate image data of portions of interest at a second resolution that is higher than the first resolution. In another embodiment, one imaging modality may be used to resolve an ambiguity, such as ghost images, in image data generated using another imaging modality.
