    Abstract: Methods, systems and computer program products for radionavigation for swimmers are described. A mobile device configured to estimate a location using radio frequency signals can estimate a position of the swimmer when the mobile device is worn on a limb of the swimmer and periodically submerged. The mobile device can supply auxiliary information to a radionavigation subsystem to correct a navigation solution affected by limb motion of the swimmer and affected by the periodic submersion of the mobile device.

    Abstract: Systems, methods and computer-readable storage mediums are disclosed for a pedometer with lag correction. In some implementations, a method comprises: determining, by a first pedometer of an electronic device, a first step count based on sensor data provided by a motion sensor of the electronic device; determining, by a second pedometer of the electronic device, a second step count based on a window of the sensor data; responsive to determining that a step was detected by the second pedometer, determining a third step count based on the window of sensor data; and determining a corrected step count based on the third step count.

    Abstract: An electronic device may include a motion sensor for detecting movement of the electronic device. Applications that run on the electronic device such as fitness applications or activity logging applications may use motion sensor data to track a user's physical activity. To avoid mischaracterizing a user's movement, motion sensor circuitry in the electronic device may supplement motion sensor data with additional information in instances where motion sensor data alone may be insufficient to distinguish between different types of physical activity. For example, information on a user's speed may be synthesized with motion sensor data to help characterize a user's movement. Information on a user's speed may be determined based on location information. The location information may, for example, be gathered using IEEE 802.11 transceiver circuitry or, in more rural areas, may be gathered using Global Positioning System receiver circuitry.
