Abstract: A fitting system for an earpiece that comprises a support structure that is configured to contact at least one of the ear canal or the concha of an ear of a user, including at least first and second spaced electrodes that are each configured to contact the user's skin, circuitry that is configured to determine an impedance between the first and second electrodes, and a controller, responsive to the determined impedance, for causing the earpiece support structure to move.

Abstract: A method for adjusting an RF amplifier is provided. The method includes determining link statistics corresponding to wireless data received by a first device. The wireless data was transmitted by a second device, such as via a Bluetooth protocol. The method further includes adjusting an RF amplifier of the first device or the second device based on the one or more link statistics. The one or more link statistics may include RSSI, PER, buffer level, audio drop data, and acknowledgement packet data. The RF amplifier may be a low noise amplifier or a power amplifier. The adjusting may include increasing or decreasing a gain of the RF amplifier. Alternatively, the adjusting may include activating or deactivating the RF amplifier.

Abstract: Various implementations include wearable devices and methods for managing respiration and user health. In some particular implementations, a wearable device includes: a mount sized to couple with a body part of a user; and a housing coupled with the mount. The housing at least partially contains: a contact element for applying pressure to the body part; and an actuator coupled with the contact element, the actuator configured to actuate the contact element in applying pressure to the body part according to a prescribed pattern. The prescribed pattern includes at least two repetitions, each repetition having: a first segment at a progressively increasing pressure; a second segment at a substantially constant pressure, following the first segment; a third segment at a progressively decreasing pressure, following the second segment; and a fourth segment at a substantially constant pressure that is less than the substantially constant pressure of the second segment.

Abstract: A method of transferring audio signals from an analog audio source to an audio sink, where the audio sink has a multiple-pin connector. A cable is coupled to the audio source and to the multiple-pin connector of the audio sink, where the cable is constructed and arranged to carry audio signals. The audio sink detects a return signal provided to the audio sink over the cable, where the audio sink is configured to interpret the receipt of a return signal as indicating that an audio source is operably connected to the audio sink by the cable. Responsive to this detecting, the audio sink receives audio signals from the audio source over the cable.

Abstract: Aspects of the present disclosure provide an electro-acoustic transducer that serves as an acoustic transducer and as an NFMI coil. The use of a single coil eliminates the need for a dedicated NFMI coil, thereby reducing design complexity and cost of production. Circuity is provided to allow selective filtering of acoustic and NFMI signals so the acoustic and NFMI signals may coexist in a frequency-divisional multiplexing fashion on a same electro-acoustic transducer coil.

Abstract: An on/off head detection system uses magnetic field intensity to determine a configuration, position, and/or orientation of a headphone. In some implementations, the system may determine whether a headphone is on or off a user's head. The system includes a magnetic field sensor configured to detect a magnetic field emitted by a magnetic field source associated with an earpiece of the headphone. A control module determines an intensity of the magnetic field and whether the intensity of the magnetic field satisfies a threshold. An operational mode associated with the headphone or an associated device is performed in response to the intensity of the magnetic field satisfying the threshold.
