4 US Patent: Filled October 10, 2001 Patent covers the position of accelerometers around the head. Patent covers algorithm used to calculate impact levels from single axis-accelerometers. System and method for measuring the linear and rotational acceleration of a body part. Riddell Inc. HITS Helmet

5 US Patent: Riddell Inc. HITS Helmet Accelerometer placement for best accuracy (spaced 120 o ° apart). Each accelerometer’s data is fed into an equation that generates a cosine wave and compares them to known data. One is chosen as a best fit using least squares regression techniques. Impact location, direction, and magnitude is found from this algorithm.

6 Patent Liability: ( ) Keep 3 accelerometers but place them at different locations. Maybe 0 o, 140 o, -140 o. Increase the number of accelerometers. Possible literal infringement. We have 3 accelerometers placed throughout the helmet at the 0 o, 120 o, -120 o locations. We do not use a cosine best fit method. We do not use single-axis accelerometers. Solution: Riddell Inc. HITS Helmet

7 US Patent: Filled June 11, 1997 Recording head movement during a sport or other activity into mass memory for later study. Memory can be local or sent wirelessly to another device’s storage medium. Helmet system including at least three accelerometers and mass memory and method for recording in real-time orthogonal acceleration. Head Acceleration-monitoring Technology (HAT)

8 Patent Liability: ( ) Remove the ‘record threshold’ and only record impacts that trigger a sideline alert. Limit the user from setting the trigger threshold too low. Do not store raw data, only calculated results. Possible literal infringement. We do record all significant head movement onto a removable memory card. Data is time stamped for future reference and study. Solution: Head Acceleration-monitoring Technology (HAT)

9 US Patent: Filled December 20, 1995 Uses LEDs mounted on helmet to notify officials, players, coach or other supervisor when a player is potentially injured. A signaling device is installed in headwear and includes sensing devices for detecting linearly and rotationally directed impacts above a selected magnitude. Helmet-mounted Injury Notification System

10 Patent Liability ( ): Possible licensing or royalty fees. Possible infringement under doctrine of equivalence. The Instrumented Football Helmet impact notification feature does not use any perceivable light or audio signals. Solution: Helmet-mounted Injury Notification System
