Abstract: Detecting user contact with one or more electrodes of a physiological signal sensor can be used to ensure physiological signals measured by the physiological signal sensor meet waveform characteristics (e.g., of a clinically accurate physiological signal). In some examples, a mobile and/or wearable device can comprise sensing circuitry, stimulation circuitry, and processing circuitry. The stimulation circuit can drive one or more stimulation signals on one or more electrodes, the resulting signal(s) can be measured (e.g., by the sensing circuitry), and the processing circuitry can determine whether a user is in contact with the electrode(s). Additionally or alternatively, in some examples, mobile and/or wearable device can comprise saturation detection circuitry, and the processing circuitry can determine whether the sensing circuitry is saturated.

Abstract: An earbud may have a housing with an ear portion and an elongated out-of-ear portion that protrudes away from the ear portion. A speaker may be aligned with a speaker port in the ear portion and may emit sound for a user. Audio playback functions and other operations may be controlled using a controller in the earbud. The controller may gather capacitive sensor data and other data and may use this data in identifying an operating mode of the earbud. Using information such as whether the earbud is in an in-ear state or an out-of-ear state or other sensor data, the controller may take actions such as pausing or resuming audio playback or adjusting playback volume. The capacitive sensor data can be gathered using capacitive sensing electrodes located on the ear portion and the stalk portion of the earbud.

Abstract: Embodiments are directed to methods, devices and systems for determining and applying a gain adjustment to sensed electrical signals. The methods can include operating a device to determine that a user is wearing the wearable electronic device and applying a test signal to a sensing electrode of the wearable device. An input impedance for the sensing electrode can be determined using the test signal. The input impedance and a baseline impedance can be used to determine a gain adjustment. An electrical signal of the user can be measured using the sensing electrode and the gain adjustment can be applied to the electrical signal. A physiological parameter of the user can be determined using the measured electrical signal having the gain adjustment applied.

Abstract: An optical sensor can be multiplexed for different clients/features including estimating information or characteristics of a user's physiological signals. Additionally, the clients/features can include estimating information or characteristics independent from a user's physiological signals. As the number of clients increase and/or as the requirements for the clients increase, flexibility can be provided to accommodate the various clients. Parallelization of the optical sensor can be used to improve performance as the number of clients increase. For example, the hardware and software architecture can assemble patterns of time slots that measure all desired light paths for the multiple clients and distribute the corresponding measurements to each client according to the client requests. In some examples, the scanning sequence can be represented by frames including slots associated with multiple clients to compress the representation for larger or more complex scan sequences.

Abstract: This relates to methods and apparatus for mitigating effects of the presence of RF communication signals. In some examples, non-linearity and rectification of the RF communication signals can become rectified in sensor circuitry such that spectral components of a frame or sub-frame timing of the RF communication signals can be aliased into the sensor circuitry output within a bandwidth of interest. In some examples, a notch filter can be employed to remove the aliased RF communication signals from the sensor output. In some examples, a sampling rate used for sampling the user's physiological signals can be generated such that the sampling of the sensor is synchronous with the RF communication signals. In some examples, the sampling rate for the sensor can be generated as an integer multiple or integer submultiple of the frame or sub-frame timing of the RF communication signals.
