Classification of impacts from sensor data
First Claim
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.

Abstract
Systems and methods are provided for classifying an impact to a head of a human being as one of a plurality of event classes. A sensor interface is 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 is configured to calculate a plurality of impact parameters from the determined acceleration at the location of interest. A pattern recognition classifier is 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. A post-processing component is configured to communicate the associated event class an observer via an associated output device.

16. A method for determining a risk of injury to a human being from a measurement at a sensor assembly comprising:
-
measuring at least one of a linear acceleration, an angular acceleration, an angular velocity and an orientation measured at the sensor assembly, the sensor assembly being located at a first location in an article worn by the human being, the article being one of a mouth guard and a lip guard; determining an acceleration at a location of interest on one of a head and a neck of the human being from the measured at least one of a linear acceleration, an angular acceleration, an angular velocity and an orientation at the first location, the first location being remote from the location of interest; calculating a plurality of impact parameters from the determined acceleration at the location of interest; associating the calculated plurality of impact parameters with an associated injury class of a plurality of injury classes, each injury class representing a range of probabilities that the human being will suffer an injury to a structure within one of the head and the neck given the calculated plurality of impact parameters; and communicating the associated event class to an observer via an associated output device. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
