Abstract

Head impact event evaluation systems and methods. A system and computer implemented method for event detection includes collecting sensor data transmitted from one or more sensor devices being attached to one or more users. The sensors transmit data when an event results in sensor data above a threshold value. At least one force is determined based on the collected sensor data. At least one force vector is determined based on a location of one or more sensors associated with the sensor devices and the determined at least one of the linear or rotational force. At least a portion of a human form is displayed with the determined force vector based on the determined at least on force vector on a display.

Core Innovation

A computer implemented method and system for event detection and analysis receive sensor data detected by a sensor attached to a head of a user, where the sensor monitors an impact parameter associated with an impact event. The method determines a time since the impact event and calculates an assessment score as a function of the impact parameter and the time since the impact event.

The method also determines an impact vector as a function of the impact parameter associated with the impact event. In determining at least one impact vector, the method translates the impact vector from a location of the sensor to an associated vector experienced by at least one other location in the head of the user, including axes translated to the brain center of mass.

The system classifies impacts with alerting in an assessment system by computing an assessment criterion score, including alerting representations. An injury prediction engine uses medical history and the assessment criterion score, where the assessment includes a recovery time weighting based on time since the impact event and then produces an alert classification.

Claims Coverage

The partial document provides two independent claims (clm-00001 and clm-00007). Across these independent claims, the inventive core is the computation of an assessment score and an impact vector from sensed impact parameter information and time since impact, together with translation of the impact vector from the sensor location to a vector experienced at other head locations.

The independent claim set covers a head-worn sensing arrangement where sensed impact parameter data and time-since-impact are used to compute an assessment score, and where an impact vector is computed and then translated from the sensor location to associated vectors at other head locations. Dependent claims refine the impact vector characterization, including axes associated with the brain center of mass and rotational direction and magnitude, and further include threshold-based alerting and time-weighted assessment scoring.
