Portable Wireless Personal Head Impact Reporting System

摘要

A system senses, analyzes, and reports a collision event experienced by a person or object. A sensor module records angular velocities over time and a processor analyzes the sensed velocities, calculates properties of angular velocities, such as jerk and jolt, compares these properties with threshold values selected to correlate to predicted severities of injury to the person or object, and transmits information regarding these properties to a communication device controlled by user-designated persons. Group tracking and communication devices are used by monitors to manage multiple persons equipped with sensor modules. The sensor modules and group tracking and communication devices are designed to be portable, attachable, and detachable so that they can be attached to different types of gear used by persons engaging in different activities.

1. A method of evaluating the severity of a collision event experienced by a person or object with another person or object, said method comprising:
sensing angular velocities of said person or object over time as a result of said collision event; calculating jerk and/or jolt from said angular velocities over time; and comparing said jerk or jolt with threshold values selected to correspond to one or more levels of severity of the collision event.
