  • Publication number: 20210325967
    Abstract: A method may include measuring an electrical parameter of an electromagnetic load having a moving mass during the absence of a driving signal actively driving the electromagnetic load, measuring a mechanical parameter of mechanical motion of a host device comprising the electromagnetic load, correlating a relationship between the mechanical parameter and the electrical parameter, and calibrating the electromagnetic load across a plurality of mechanical motion conditions based on the relationship.

  • Publication number: 20210328535
    Abstract: A method for minimizing undesired movement of a moving mass of an electromagnetic load may include detecting undesired movement of the moving mass based on real-time measurements of one or more parameters associated with the electromagnetic load and, responsive to detecting undesired movement of the moving mass, affecting a signal applied to the moving mass to reduce the undesired movement.

  • Patent number: 11139767
    Abstract: According to embodiments described herein, there are provided methods and apparatus for providing a driving signal to a transducer, wherein the driving signal is output by an amplifier. A method comprises receiving an indication of a voltage and a current of the driving signal; based on an electrical model of the transducer and the voltage and the current of the driving signal, estimating an estimated electrical response of the transducer representative of movement of a mass in the transducer; comparing the estimated electrical response to a desired electrical response; and controlling the driving signal based on the comparison.

  • Patent number: 11121661
    Abstract: A method for minimizing settling of a moving mass of an electromagnetic load may include determining a polarity and a magnitude of a velocity of the moving mass based on real time measurements of one or more parameters associated with the electromagnetic load and based on the polarity and the magnitude of the velocity, generating a braking signal to be applied to the moving mass that opposes the polarity of the velocity.

  • Publication number: 20200396538
    Abstract: A method for minimizing post-playback oscillation during playback of a haptic playback waveform to a haptic transducer may include determining whether a frequency response of the haptic playback waveform has a notch with a notch frequency at approximately a resonant frequency of the haptic transducer and, responsive to the notch frequency differing from the resonant frequency, modifying the haptic playback waveform for playback to the haptic transducer by shifting the notch frequency to approximately the resonant frequency.
