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.

Claims

1. A computer implemented method for event detection comprising:

collecting sensor data detected by a sensor attached to a head of a user, the sensor monitoring an impact parameter associated with an impact event;

determining a time since the impact event;

calculating an assessment score as a function of the impact parameter and the time since the impact event.

2. The method of claim 1, wherein the impact event comprises a plurality of impact events and further wherein the step of calculating comprises determining an assessment score for each one of the plurality of events and summing the plurality of assessment scores to produce a total assessment score.

3. The method of claim 1, further comprising determining an impact vector as a function of the impact parameter associated with the impact event.

4. The method of claim 3, wherein determining the impact vector further comprises associating the impact vector with a center of mass of a brain of the user.

5. The method of claim 3, wherein determining an impact vector comprises determining a direction and magnitude of rotation of the head of the user as a function of the impact event.

6. The method of claim 3, wherein the step of determining at least one impact vector further comprises translating 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.

7. The method of claim 1, further comprising providing an alert when the assessment score is above an assessment threshold.

8. The method of claim 1, wherein providing an alert comprises at least one of an audible or visual signal.

9. A system configured to analyze impact event data, comprising:

a sensor configured to be worn on a head of a user, the sensor being capable of sensing an impact parameter;

a computer processor; and

a memory in communication with the processor and the sensor, the memory containing stored programming instructions operable by the processor to;

receive impact parameter information related to the sensed impact parameter; and

calculate an assessment score as function of the impact parameter information and the time since the impact event.

10. The system of claim 9, wherein the impact event comprises a plurality of impact events, and further wherein a total assessment score is a sum of the assessment score for each one of the plurality of impact events.

11. The system of claim 9, wherein the assessment score is multiplied by a weight related to the time since the impact event, the weigh equaling zero when the time is more than 48 hours, the weight equaling one when the time is less than 24 hours, and the weight equaling 1-0.04167(time-24) when the time is between 24 and 48 hours.

12. The system of claim 11, wherein the assessment score equals the weight times an impact score, the impact score equaling 0 when the impact parameter information is less than 50 g, the impact score equaling ⅓

when the impact parameter information is greater than or equal to 50 g but less than 70 g, the impact score equaling ½

when the impact parameter information is greater than or equal 70 g but less than 90 g, and the impact score equaling 1 when the impact parameter information is greater than or equal to 90 g.

13. The system of claim 12, further comprising a display, the display configured to present an indicator related to the assessment score.

14. The system of claim 9, wherein the programming instructions further cause the processor to determine an impact vector as a function of the impact parameter associated with the impact event.

15. The system of claim 14, wherein the impact vector is associated with a center of mass of a brain of the user.

16. The system of claim 9, wherein the programming instructions further cause the processor to determine a rotational direction and magnitude of the impact event as a function of the impact parameter information.

17. The system of claim 18, further comprising a display, the display presenting a graphical depiction of rotational direction and magnitude of the impact event.

18. The system of claim 9, wherein the programming instructions further cause the processor to determine an impact vector as a function of the impact parameter associated with the impact event, the processor further translating 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.

19. The system of claim 9, further comprising a user interface, the processor causing the user interface to provide an alert when the assessment score is above an assessment threshold.

20. The system of claim 18, wherein providing an alert comprises at least one of an audible or visual signal.
