  • Detection and prevention of non-linear excursion in a haptic actuator
    Patent number: 12159528
    Abstract: A method for determining and mitigating over-excursion of an internal mass of an electromechanical transducer may include measuring a sensed signal associated with the electromechanical transducer in response to a driving signal driven to the electromechanical transducer, determining a non-linearity value based on the sensed signal, mapping the non-linearity value to a probability of over-excursion of the internal mass, and applying a gain to a signal path configured to generate the driving signal based on the probability.

  • Frequency-domain haptic waveform compensation for haptic transducers
    Patent number: 11641546
    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.

  • Methods and apparatus for outputting a haptic signal to a haptic transducer
    Patent number: 11069206
    Abstract: Embodiments described herein provide methods and apparatus for outputting a haptic signal to a haptic transducer. A method comprises storing a representation of a part of the haptic signal comprising a first information point indicating a first amplitude and at least one first frequency of the part of the haptic signal at a first time, wherein the representation is associated with a user experience; responsive to receiving an indication of occurrence of the user experience, determining the haptic signal based on the first information point such that the part of the haptic signal has the first amplitude and the at least one first frequency at the first time. The method may further comprise outputting the haptic signal to the haptic transducer.
