1. A system for classifying an impact to a head of a human being as one of a plurality of event classes, the system comprising: a sensor assembly, located in an article worn by the human being, positioned at an associated measurement point on the head and configured to measure at least one of a linear acceleration, an angular acceleration, an angular velocity, and an orientation of the head at the associated measurement point during the impact to provide the sensor data, wherein the location of interest is remote from the associated measurement point, the worn article being one of a mouth guard and a lip guard; a sensor interface configured to determine an acceleration at a location of interest on the human being from provided sensor data in response to the impact; a feature calculation component configured to calculate a plurality of impact parameters from the determined acceleration at the location of interest; a pattern recognition classifier configured to associate the impact with an associated event class of at least three associated event classes according to the calculated plurality of impact parameters; and a post-processing component configured to communicate the associated event class to an observer via an associated output device.
