1. A system for determining the acceleration delivered to an object as a result of an impact, the system comprising:

  • a plurality of sensor modules configured to detect an acceleration force applied to a user'"'"'s head,wherein at least one of said sensor modules is embedded in an earpiece worn inside in car of the user, and another of said sensor modules is mounted in a helmet worn by the user,wherein each sensor module comprises a 3-axis linear accelerometer, a sensor interface and control unit, and a wireless data and power unit,wherein at least one of said sensor modules includes a gyroscope;

    a wireless data link mounted inside the helmet;

    an acceleration data processing module comprising computer-executable code stored in non-volatile memory;

    a processor;

    a memory; and

    a communications means,wherein said acceleration data processing module, said processor, said memory, and said communications means are operably connected and are configured to;

    receive acceleration data from said plurality of sensors via said wireless data link; and

    analyze said acceleration data collected by said sensor moduleswherein sensor data from the earpiece sensor module is used to correct for inaccuracies in sensor data from the helmet sensor module caused by the helmet moving independently of the user'"'"'s head in response to an impact.
