  • Patent number: 10779084
    Abstract: Embodiments are described for a method for localizing a set of speakers (106) and microphones (108), having only the times of arrival between each of the speakers and microphones. An autodiscovery process (107) uses an external input to set: a global translation (3 continuous parameters), a global rotation (3 continuous parameters), and discrete symmetries, i.e., an exchange of any axis pairs and/or reversal of any axis. Different time of arrival acquisition techniques may be used, such as ultrasonic sweeps or generic multitrack audio content. The autodiscovery algorithm is based in minimizing a certain cost function, and the process allows for latencies in the recordings, possibly linked to the latencies in the emission.

  • Patent number: 10728681
    Abstract: Embodiments are provided for intelligently activating an amplifier in a playback device based on proximity detection. The playback device may be in a quasi-idle state when the playback device is not rendering media content. The quasi-idle state of the playback device may involve an amplifier in the playback device being inactive, while some other components or modules of the playback devices remain active. The playback device may include a proximity sensor configured to detect movement relative to the playback device. If movement is detected indicating that a user input to cause the playback device to render media content is anticipated, the amplifier may be pre-emptively activated such that the playback device enters an active state from the quasi-idle state. In some cases, the playback device may send a message to one or more other playback devices to cause the other playback devices to enter an active state.

  • Patent number: 10714116
    Abstract: Various technologies described herein pertain to active noise cancellation in the interior of a vehicle. In exemplary embodiments, a microphone mounted on the vehicle outputs an audio signal indicative of noise emitted by a noise source. A computing system of the vehicle determines a position of the noise source based upon sensor signals output by sensors mounted on the vehicle. The computing system further determines a position of a passenger in the vehicle based upon a sensor mounted inside the vehicle. The computing system generates a complementary signal that is configured to attenuate the noise based upon the audio signal, the position of the noise source, and the position of the passenger. The complementary signal is then output by way of a speaker in the interior of the vehicle.

  • Patent number: 10701485
    Abstract: One embodiment provides a method comprising determining a potential energy in a loudspeaker, a kinetic energy in the loudspeaker, and an electrical energy in the loudspeaker based on a physical model of the loudspeaker. The method further comprises determining a total energy stored in the loudspeaker based on the potential energy, the kinetic energy, and the electrical energy. The method further comprises determining a maximum potential displacement of a diaphragm of a speaker driver of the loudspeaker based on the total energy, and limiting the total energy stored in the loudspeaker by attenuating a source signal for reproduction via the loudspeaker. An actual displacement of the diaphragm during the reproduction of the source signal is controlled based on the attenuated source signal.

  • Patent number: 10694107
    Abstract: A process for the elimination of thermal interferences in the infrared and video fire detection at an early stage in waste incineration plants, recycling facilities, warehouses and the like. The process is characterized by an additional noise and vibration analysis, by measuring the noise level of vehicles situated in the area to be detected or other thermal interference sources, with a distinction in measuring the noise level between day mode and night mode. The volume thresholds can thus be determined and be used as a threshold for determining whether a fire extinguishing sequence should be triggered.
