Abstract

A sensor module generates sensor data in response to an impact to protective headgear, wherein the sensor module includes an accelerometer and a gyroscope and wherein the sensor data includes linear acceleration data and rotational velocity data. A device processing module generates event data in response to the sensor data. A device interface sends the event data to a monitoring device when the device interface is coupled to the monitoring device.

Claims
