DETECTION AND CHARACTERIZATION OF HEAD IMPACTS
First Claim
1. A method for determining an acceleration at a location of interest within one of a user'"'"'s head and neck, comprising:
- producing at least one of linear acceleration data, angular acceleration data, angular velocity data, and orientation data using at least one sensing device substantially rigidly attached to an ambient-accessible surface of the user'"'"'s head;
representing the location of interest relative to a position of the at least one sensing device as a time-varying function;
calculating an acceleration at the location of interest as a function of the data produced at the sensing device and the time-varying function representing the location of interest; and
providing the calculated acceleration at the location of interest to at least one of the user and an observer in a human-perceptible form.

Abstract
Systems and methods are provided for determining an acceleration at a location of interest within one of a user'"'"'s head and neck. At least one of linear acceleration data, angular acceleration data, angular velocity data, and orientation data is produced using at least one sensing device substantially rigidly attached to an ambient-accessible surface of the user'"'"'s head. The location of interest is represented relative to a position of the at least one sensing device as a time-varying function. An acceleration at the location of interest is calculated as a function of the data produced at the sensing device and the time-varying function representing the location of interest. The calculated acceleration at the location of interest is provided to at least one of the user and an observer in a human-perceptible form.

25. A system for characterizing an impact to a head of an athlete during an athletic event comprising:
-
a sensor assembly mounted within one of a mouth guard and a lip guard worn by the athlete and configured to measure at least one of the linear acceleration, angular velocity, angular acceleration, and orientation of the sensor assembly; a data transform component operatively connected to the sensor assembly and configured to calculate the acceleration of at a center of gravity of the head from the measured at least one of the linear acceleration, angular velocity, angular acceleration, and orientation of the sensor assembly and a position of the sensor assembly relative to the center of gravity of the head; and a system interface configured to provide the calculated acceleration at the center of gravity to one of the athlete, a coach of the athlete, a family member of the athlete, a trainer of the athlete, an official associated with the athletic event, and an audience associated with the athletic event. - View Dependent Claims (26, 27)
