    Abstract: A mobile device includes a pedometer function that calculates an estimated distance based on sensor measurements. The sensor measurements are used to determine a step frequency of the user, which is used to estimate the distance traveled by the user. To correct for the unique step frequency of the user, a calibration factor is calculated that can be multiplied by the estimated distance to improve the accuracy of the distance estimate. New calibration factors resulting from calibration trials are assigned to step frequency bands. An average calibration factor is calculated for each frequency band. The average calibration factors of the bands are updated to ensure that the average calibration factor of any given band is greater than or equal to the average calibration factors in all lower bands.

    Abstract: A host device can establish a verified session with a wearable device. The host device can determine whether the verified session is in progress. In accordance with a determination that the verified session is in progress, the host device can provide a user interface to request confirmation that the identifier is to be provided to the wearable device. The host device can receive an input at the user interface and, in accordance with a determination that the input indicates a confirmation that the identifier is to be provided to the wearable device, the host can identify a user identifier to provide to the wearable device, and transmit the user identifier to the wearable device.

    Abstract: A mobile device uses externals microphone signals to improve the estimate of background noise that it computes. In order to improve voice quality in a first signal that is produced by an internal microphone, the mobile device identifies an external microphone device within proximity of the mobile device. The mobile device establishes a wireless connection with the external microphone device. The mobile device receives a second signal from the external microphone device through the wireless connection. The second signal is produced by a microphone of the external microphone device. The mobile device generates a noise profile based on the second signal, and then suppresses background/ambient noise from the first signal based on the noise profile. Other embodiments are also described.

    Abstract: Systems and methods for processing data from a motion sensor to detect intentional movements of a device are provided. An electronic device having a motion sensor may process motion sensor data along one or more dimensions to generate an acceleration value representative of the movement of the electronic device. The electronic device may then determine whether the acceleration value changes from less than a low threshold, to more than a high threshold, and again to less than the low threshold within a particular amount of time, reflecting an intentional movement of the electronic device by the user. In response to determining that the acceleration value is associated with an intentional movement of the electronic device, the electronic device may perform a particular event or operation. For example, in response to detecting that an electronic device has been shaken, the electronic device may shuffle a media playlist.
