Patent number: 11304001Abstract: A method for detecting wind using a microphone and a speaker of an electronic device. The method obtains a microphone signal produced by the microphone. The method obtains a speaker input signal produced by the speaker that is emulating a microphone capturing ambient sound in an environment through the speaker. The method determines a coherence between the microphone signal and the speaker input signal and determines whether the coherence is below a coherence intensity threshold. In response to determining that the coherence is below the coherence intensity threshold, the method determines a presence of wind in the environment.Type: GrantFiled: May 11, 2020Date of Patent: April 12, 2022Assignee: APPLE INC.Inventors: Nikolas T. Vitt, Joyce E. Gorny, Thomas M. Jensen, Jeffrey N. Gleason, Tyrone T. Chen

Patent number: 10302456Abstract: Various embodiments include a position sensor configuration that compensates for a bias field offset. The position sensor configuration may be used for position sensing of components, such as camera components, that are movable via an actuator (e.g., a voice coil motor actuator). In some embodiments, the actuator may include an asymmetric magnet arrangement that produces an asymmetric magnetic field. The asymmetric magnetic field may include one or more bias field components that are offset relative to one or more axes. In some examples, the position sensor configuration may include one or more magnetic field sensor packages. Individual ones of the magnetic field sensor packages may include a magnetic field sensor and one or more compensation magnets. The compensation magnets may be configured to contribute to one or more compensation magnetic fields that counteract the bias field components such that the compensation magnetic fields compensate for the bias field offset.Type: GrantFiled: September 13, 2017Date of Patent: May 28, 2019Assignee: Apple Inc.Inventors: Hyuk J.
