A device testing capability is presented herein. In one example, an athletic monitoring device may include or be associated with multiple types of movement sensors and switch between the sensors or use both depending on various factors including type of workout. A portion of the data structure is forwarded to a receiving forum participant, thereby communicating the digitized speech from the transmitting forum participant. The second phone device reception slot includes a second data synchronization port configured to receive and transmit data with respect to a second phone device when the second phone device is disposed within the second phone device reception slot and is in electrical contact with the second data synchronization port. The sharpness index is used to minimize a cost function for determining parameters for use by the image capture device. A ground-contacting member is movably coupled to the platform.
