In addition, at high voltages, the circuit has a high impedance at high frequencies but a low impedance at low frequencies. In biased transducers, this circuit may be used between the charge pump and the transducer. In general, the circuit may be provided in a signal path between the transducer and the amplifier. The circuit has as an advantage that at startup, low frequency signals at high intensities may overload the amplifier, whereas at operation, higher frequency signals are desired fed to the amplifier at the same intensity. This is facilitated by the circuit.

  • Patent number: 10182290
    Abstract: A computing device is provided, comprising a processor configured to receive a set of measurements of a vector x of acoustic data, including noise, interference, and a signal of interest. The processor may express x in a frequency domain discretized in a plurality of intervals. For each interval, the processor may generate an estimate ?x of a covariance matrix of x. For each ?x, the processor may use acoustic imaging to obtain an estimate ? of a spatial source distribution. For each ?, the processor may remove the signal of interest to produce an estimate ? of a noise and interference spatial source distribution. For each ?, the processor may generate an estimate ?n of a noise and interference covariance matrix. The processor may generate a beamformer configured to remove noise and interference from the acoustic data, wherein the noise and interference at each frequency are identified using ?n.

  • Patent number: 10104484
    Abstract: A computer-implemented system and method for identifying and locating an emitted acoustic signal from a source entity is disclosed. The system and method is capable of distinguishing between source entities of the same type. The system and method may further allow a user of the system to observe the movement of a source entity in real-time from a remote location as well as access stored data representative of the movement of the source entity from a remote location. The system and method is capable of identifying the identity of a source entity by using an average sound source comparing a received emitted acoustic signal from the source entity to a database of sounds. The system and method is capable calculating the source entity's distance and direction from an origin input sensor for each occurrence of emitted acoustic signals received from the source entity.

  • Patent number: 10089998
    Abstract: An electronic device includes a plurality of microphones, each pair of microphones in the plurality of microphones being a respective distance from one another. The electronic device also includes a beamformer functional block that receives audio signals from each of the microphones. The beamformer functional block detects a dominant microphone from among the plurality of microphones based on the audio signals from each of the microphones and the distances between the microphones, the dominant microphone being in a closest direction to a source of desired audio. The beamformer functional block also detects interfering audio signals based on phase coherence between audio signals from the dominant microphone and audio signals from other microphones in the plurality of microphones. The beamformer functional block generates a beamformed audio output signal based on the audio signals and the interfering audio signals from each of the microphones.

    Abstract: Various embodiments provide for an acoustically configurable microphone device that can adjust various parameters affecting sensitivity, acoustic overload point, signal to noise ratio, sample rate, and other parametric choices that affect the performance and function of the acoustic sensor based on commands received via acoustic communications. An acoustic analysis engine can analyze acoustic communications received to determine whether or not the acoustic communication contains a command associated with configuring the microphone. If the acoustic communication is determined to contain a configuration command, a controller on the microphone can implement the configuration command. The acoustic communications can be at ultrasonic frequencies in some embodiments so that the acoustic communications are outside the range of human hearing.
