Abstract: A system and method for tracking running activity that includes an activity monitor device with an inertial measurement system, a communication module, a processor configured to generate a set of biomechanical signals from kinematic data collected from the inertial measurement system, a housing that internally contains the inertial measurement system, the communication module, and the processor, and an electrical interface exposed on the external side of the housing; and a user application operable on a second computing device distinct from the activity monitor device; wherein communication and generation of biomechanical signals are operable in many modes.

Abstract: A system and method for customizing biomechanical wearable sensors can include a customizable biomechanical processing layer, activity model layer, and/or device communication and processing management. The system and method can include monitoring biomechanical signals at a first set of wearable sensors configured in an initial biomechanical processing configuration; selecting a configuration option for the first set of wearable sensors; delivering the configuration option to the at least one wearable sensor; and monitoring biomechanical signals according to an altered biomechanical processing configuration that is altered according to the configuration option.
