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: Robust estimation of a characteristic of a user's physiological signals can be achieved by filtering or classifying samples. Rather than estimating the characteristic of the user's physiological signals based on each sample at a first wavelength and a second wavelength, a robust system and method can, in some examples, estimate the characteristic using samples at the first wavelength and the second wavelength that meet one or more criteria and filter out samples that fail to meet the one or more criteria. In some examples, the system and method can weight samples based on the one or more criteria, and estimate the characteristic using the weighted samples. Samples failing to meet the one or more criteria can be given less weight or no weight in the estimation. The one or more criteria can include a criterion based on at least the physiological signal at a third wavelength.

Abstract: A wearable electronic device (e.g., an electronic watch) may detect and analyze one or more sensing signals corresponding to light detected by the device to determine whether the device is in a sensing state (e.g., the device is within a maximum sensing distance of a user). If the wearable electronic device is in the sensing state, the device may determine one or more physiological parameters from the same signals used to determine whether the device is in the sensing state.
