  • Patent number: 11998391
    Abstract: Systems and methods of 3D ultrasound imaging with one or more “thick-slice” 3D ultrasound imaging zones and one or more 2D ultrasound zones using a multi-zone, multi-frequency image reconstruction scheme with subzone blending. The first zone can be a thick-slice imaging zone and the second and third zones are 2D imaging zones. The first zone and the second zone can be thick-slice imaging zones and the third zone can be a 2D imaging zone. The first zone can be a 2D imaging zone, the second zone can be a thick-slice imaging zone and the third zone can be a 2D imaging zone. A method includes imaging a first zone using plane wave imaging, a second zone using tissue harmonic imaging, and a third zone using fundamental and subharmonic deep imaging. The depth of each zone can vary based on the ultrasonic array and the F# used for imaging the zone.

  • Patent number: 11373665
    Abstract: The disclosure includes a voice isolation system comprising an acoustic echo-cancelation subsystem configured to receive a plurality of input signals, subtract an interference component from the input signals, and provide a plurality of output signals. The system also includes an adaptive beamformer subsystem configured to receive the plurality of output signals from the acoustic echo-cancelation subsystem and compute a signal-to-noise ratio enhanced signal based on the received output signals. The system also includes a residual noise suppressor subsystem configured to attenuate at least one portion of the SNR enhanced signal received from the adaptive beamformer subsystem based on the at least one portion having an SNR below a predetermined SNR threshold. The system also includes an automatic gain control subsystem configured to process a signal outputted from the residual noise suppressor subsystem and transmit a resulting signal as an output signal.

  • Patent number: 10516960
    Abstract: An audio speaker system for a home theater including a number of microphones, a number of speakers, each speaker located at a different location in a room, and a processor electrically connected to the plurality of microphones and wirelessly connected to the plurality of speakers. The processor is configured to generate an audio signal to send to each speaker of the plurality of speakers, output audio from each speaker of the plurality of speakers based on the audio signal, receive the audio at each microphone from each speaker of the plurality of speakers, determine a location of each speaker relative to the plurality of microphones based on the received audio at each microphone, and assign an audio channel to each speaker based on the determined location.
