Detection and characterization of head impacts
First Claim
1. A non-transitory computer readable medium storing executable instructions executable by an associated processor to perform a method for determining an acceleration at a location of interest within one of a user'"'"'s head and neck, comprising:
- receiving, at a processor, sensor data including one of linear acceleration data, angular acceleration data, angular velocity data, and orientation data, the sensor data being received using a sensor assembly remote from the location of interest and mounted on or within one of a mouthpiece, an instrument mounted in the auditory canal, an instrument mounted in the nasal canal, and an instrument inserted into eyewear;
accessing registration data relating to a position of the sensor assembly relative to a position of the location of interest;
calculating an acceleration at the location of interest using a time varying function based on the sensor data, the time-varying function representing the location of interest as a linear combination of the linear acceleration and twice a cross-product of the angular velocity with a relative velocity between the sensor position and the location of interest; and
providing the acceleration to one of the user and an observer at an associated display.

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.

11. A system for characterizing an impact to a user comprising:
-
a sensor assembly configured to measure a linear acceleration and an angular velocity at a sensor position, the sensor assembly being mounted on or within one of a mouthpiece, an instrument mounted in the auditory canal, an instrument mounted in the nasal canal, and an instrument inserted into eyewear; a data transform component operatively connected to the sensor assembly and configured to represent a location of interest in one of the head and the neck of the user relative to the sensor position as a time-varying function, in which a distance between the location of interest and the sensor position can vary with time, and to calculate an acceleration at the location of interest as a linear combination of the linear acceleration and a cross-product of the angular velocity with a relative velocity between the sensor position and the location of interest; registration data accessible by the data transform component and establishing a relative position of the sensor assembly and the location of interest; and a system interface configured to provide the calculated acceleration at the location of interest to a user at an associated display. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
