Abstract: Gaps between transmitters and receivers in wireless power systems and related systems, methods, and devices are disclosed. A housing includes an internal surface configured to face a receive power coil and an external surface configured to face a wireless power transmitter. The external surface is shaped to define one or more gaps between the external surface and a surface of the wireless power transmitter responsive to placement of the external surface into engagement with the surface of the wireless power transmitter. An electronic device includes a receive power coil and a barrier including an internal surface facing the receive power coil and an external surface configured to face a transmit power coil. The external surface defines a gap between the external surface and a surface of the wireless power transmitter responsive to placement of the external surface in engagement with the surface of the wireless power transmitter.

Abstract: Audio operating systems and related systems, methods, and devices are disclosed. A portable electronic accessory includes a microphone to receive audio inputs, a speaker to provide audio outputs, and control circuitry including a cellular data radio circuit and an application processor. The cellular data radio circuit is configured to communicate with a cloud server through a cellular data network. The application processor is configured to execute at least a portion of an audio operating system. The audio operating system is configured to host audio software applications provided by the cloud server. The audio software applications are configured to operate free from graphical user interface elements based at least in part on the audio inputs and the audio outputs. The cloud server includes one or more data storage devices including software application code for audio software applications to be hosted by an audio operating system (OS) of the portable electronic accessory.

Abstract: Noise-canceling audio devices may include a first vibration member, a second vibration member, and a microphone supported by a housing. A feedback, noise-cancelation circuit may be operatively connected to the microphone, the feedback, noise-cancelation circuit configured to generate a first portion of a modified audio signal by combining an audio signal with a noise-canceling signal generated in response to a signal from the microphone to at least partially cancel at least a portion of an audible response of the second vibration member. A feed-forward, noise-cancelation circuit may be operatively connected to the microphone, the feed-forward, noise-cancelation circuit configured to compare the signal from the microphone to a predetermined SPL profile and generate a second portion of the modified audio signal configured to at least partially cancel environmental noise, the feedback, noise cancelation circuit configured to output the modified audio signal only to the first vibration member.

Abstract: Noise-canceling headphones may include a headband, an audio input, and earcups supported proximate ends of the headband. A first vibration member operatively connected to the audio input, a second vibration member operatively connected to the audio input, and a microphone may be supported by a housing of at least one of the earcups. A feedback, noise-cancelation circuit configured to reduce a user's perception of a portion of an audible response of the second vibration member may be operatively connected to the microphone. The feedback, noise-cancelation circuit may be configured to modify an audio signal from the audio input at least in part based on a signal from the microphone and send the modified audio signal to the first vibration member.

Abstract: Methods of operating headphones may involve filtering an input signal into a first filtered input signal and a second filtered input signal utilizing a filter. The second filtered input signal may be sent directly to a tactile vibration driver and tactile vibrations may be produced. A fixed, predetermined inverse transfer function may be applied to the first filtered input signal, generating an anti-wave signal. The anti-wave signal may be summed with the first filtered input signal, generating an output signal. Alternatively, a fixed, predetermined transfer function may be applied to the first filtered input signal, generating a modified input signal. The modified input signal may be subtracted from the first filtered input signal, generating an output signal. Audio sound waves may be produced with an acoustic driver responsive to the output signal, reducing effects of incidental acoustic noise generated by the tactile vibration driver.

Abstract: Presented are systems and methods that analyze an individual's state based on selected criteria, and then adaptively provide stimuli to affect the individual's performance compared to established benchmarks and pre-set plans. The methods or systems can provide audio and/or tactile inputs to a human subject to obtain a specific performance state. A music or sound selection engine considers the sensory and environmental inputs and selects the appropriate music or auditory stimulus, with the intent to reach a desired state of flow. The methods and systems can employ multiple measurements of personal data that can correlate to the emotional state of a subject. By manipulating stimuli delivered to an individual, ultimate performance can be improved over various planning horizons.

Abstract: Noise-canceling headphones may include a headband, an audio input, and earcups supported proximate ends of the headband. A first vibration member operatively connected to the audio input, a second vibration member operatively connected to the audio input, and a microphone may be supported by a housing of at least one of the earcups. A feedback, noise-cancelation circuit configured to reduce a user's perception of an undesirable audible response of the second vibration member may be operatively connected to the microphone. The feedback, noise-cancelation circuit may be configured to modify an audio signal from the audio input at least in part based on a signal from the microphone and send the modified audio signal to the first vibration member. The modified audio signal may be configured to at least partially cancel at least a portion of an audible response of the second vibration member.

Abstract: A wireless earbud system includes a first earbud assembly and a second earbud assembly. Each of the first earbud assembly and the second earbud assembly include a housing, an audio driver disposed within the housing, and a wireless receiving unit operatively coupled to the audio driver. The wireless receiving unit is configured to receive a wireless data signal and drive the audio driver based on audio data transmitted in the wireless data signal. The wireless earbud system may also include a tether with a first end and a second end. The first end of the tether is configured to removably couple to the first earbud assembly by a first detachable connector, and the second end of the tether is configured to removably couple to the second earbud assembly by a second detachable connector. Methods also relate to the wireless earbud system.
