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.

Detection and characterization of head impacts

Systems and methods are provided for registering a sensor assembly, implemented on a base apparatus, to a desired location associated with a head of a user. A position of a reference point on the base apparatus is determined relative to an external anatomical landmark of the user. A position of the external anatomical landmark is determined relative to the desired location. The position and orientation of the sensor assembly is determined relative to the desired location according to the determined position and orientation of the sensor assembly relative to the reference point, the determined position of the reference point relative to the external anatomical landmark, and the position of the external anatomical landmark relative to the desired location.

Registration of head impact detection assembly

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.

Classification of impacts from sensor data

Systems and methods are provided for enhancing a presentation of an athletic event. Data is received at a sensor located at a first location on a first athlete. The data represents an impact applied to the first athlete by a second athlete. One of an acceleration and a force at a second location on the first athlete induced by the impact is determined. A representation of the determined one of the acceleration and the force at the second location on the first athlete is displayed to an audience of the athletic event.
