  • Patent number: 11146887
    Abstract: An in-vehicle noise-cancellation system may optimize far-end user experience. The noise-cancellation system may incorporate real-time acoustic input from the vehicle, as well microphones from a telecommunications device. Audio signals from small, embedded microphones mounted in the vehicle can be processed and mixed into an outgoing telecom signal to effectively cancel acoustic energy from one or more unwanted sources in the vehicle. Multiple microphones may be mounted to headrests and spaced apart in one or more directions to give an indication of the direction of incoming sound from one or more listening zones so that sounds from certain zones may be suppressed. Unwanted noise captured by the embedded microphones may be used as direct inputs to the noise-cancellation system. As direct inputs, these streams can, therefore, be cancelled from the outgoing telecom signal, thus providing the user's far-end correspondent with much higher signal-to-noise ratio, call quality, and speech intelligibility.

  • Patent number: 11123225
    Abstract: A wireless audio system suppresses exterior noise and directs desired sound into a user's ear canal. An audio system may include an earplug to create a seal in the interior of an ear canal. The earplug may include a ribbed exterior profile and can be flexible to create the seal. A speaker may be inserted within the earplug. A channel may extend through a body of the earplug to direct sound into a user's ear canal. A proximal opening may extend from the speaker to the channel of the earplug, and an audio wire may be connected to the speaker. The audio wire may connect to a wireless receiver, or other receiver, to allow audio data to pass through the wire and to the speaker, where it can be converted to audio that is passed directly into the ear canal of the user.

  • Patent number: 11120814
    Abstract: Microphone signals are received from microphones of a computer device. Each microphone signal of the microphone signals is acquired by a respective microphone of the microphones. A previously unselected microphone is selected from the microphones as a reference microphone, which generates a reference microphone signal. An adaptive filter is used to create, based on microphone signals of the microphones other than the reference microphone, predicted microphone signals for the reference microphone. Based on the predicted microphone signals for the reference microphone, an enhanced microphone signal is outputted for the reference microphone. The enhanced microphone signal may be used as microphone signal for the reference microphone in subsequent audio processing operations.

    Abstract: An image capture device includes a processor for wind noise processing. The processor receives signals from a first microphone, a first plurality of microphones, and a second plurality of microphones. The processor may segment each signal into low frequency bins and high frequency bins. The processor may select a minimum level signal bin for each low frequency bin. For the high frequency bins, the processor may select a minimum level signal bin for a first group of microphones or a second group of microphones. The processor may generate a composite signal by combining the selected minimum level signal bins for each low frequency bin and the selected minimum level signal bins for each high frequency bin.

  • Patent number: 11089416
    Abstract: A head-mounted wearable device provides many functions to a user. The functions may be provided based in part on whether the device is being worn (donned) or not worn (doffed). Force sensing resistors in the device provide output indicative of forces associated with wearing the device. A time series of values indicative of the magnitude of a force may be determined. An increase or decrease in force values measured at different times may indicate that the device has been donned or doffed, respectively. If a subsequent force value does not differ substantially from a previous force value, this may indicate that the device has remained donned or doffed.

    Abstract: An amplifier having one or more channels where each channel includes a two half bridges (a master and slave sub-channel). The sub-channels can be connected either in parallel or in a full-bridge configuration via internal switches that route signals to a pair of speaker jacks. One switch in the amplifier has a first position that selectively connects the outputs of the master and slave sub-channel to the same input of the speaker load so that the two sub-channels will drive the speaker load in parallel and a second position where the output of the slave sub-channel is connected to another input of the speaker load so that the master sub-channel and the slave sub-channel will drive the speaker load in a Full-bridge configuration.
