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 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 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.

18. A method for determining a risk of injury to a human being comprising:
-
measuring at least one of a linear acceleration, an angular acceleration, an angular velocity and an orientation at a first location on the human being; 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 an observer via an associated output device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
