4. »Patent #: 6,826,509 B2 »Filed: 10-10-2001 »Date of Patent: 11-30-2004 »Title: System and Method for Measuring the Linear and Rotational Acceleration of a Body Part »Sensor Type/ Placement Claims: ˃ 2&3 state single or multi-axis accelerometers may be used ˃ 12, 13 & 14 refer directly to head placement being either in a helmet or headband ˃ 18 claims the sensors may be mounted on any “geometric shape” on the body »Data Transmissions Claims: ˃ 10 covers wired transmission ˃ 11 covers radio transmission »Data Processing Claims: ˃ 17 A hit profile is created using normalized vectors to show a hit occurred ˃ 42 Employs a least squares regression model to determine best fit profile

5. »Patent Application #: 20110181419 »Filed: 07-28-2011 »Title: Head Impact Event Reporting System »Claim 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. »Main Differentiating Factor: Data Processing ˃ Claim 10: a total assessment score is a sum of the assessment score for each one of the plurality of impact events. ˃ Claim 11: …wherein the assessment score is multiplied by a weight related to the time since the impact event… ˃ Claim 12: …the assessment score equals the weight times an impact score…

6. »Patent Application #: 20110184663 »Filed: 10-10-2001 »Title: Head Impact Analysis and Comparison System »Claim 1: A computer implemented method for head impact analysis comprising: receiving impact data related to an impact parameter for an impact event experienced by a head of a user; comparing the impact data to previously stored impact parameter data in a data store, wherein the previously stored impact parameter data is associated with prior impact events; and generating an association between the impact event and one or more of the prior impact events. »Claim 16: The computer implemented method of claim 15, wherein the stored programming instructions further cause the processor to determine a percentage of associated events in which the prior impact events experienced a concussion.

7. »Literally infringing functions ˃ Accelerometers mounted on head ˃ Accelerometers measure acceleration on the head ˃ Sensor data transmitted wirelessly to “base-station” ˃ Sensor data is processed to determine impact force and location »Answer: »Obtain license/ pay royalty fee

8. »Infringement under doctrine of equivalents ˃ Data from head mounted sensors is processed to predict potential brain injury »Answer: »Use gyroscopes to collect the rotational data »Patent a better way to process the stored data and then co-license or sell rights (What use is the device if it can’t predict well?)

9. Is not binary -> Current: Concussed or not concussed (stupid thresholds) Proposed Method- Create an adaptive network ˃ Has an initial training set of size n created from PNG data ˃ Once system is trained it will be able to make predictions but may still be trained with available values to refine output ˃ System will output predicted regional change in brain tissue morphology -> This allows better prediction to whether or not critical damage has occurred and how to prevent further damage to regions showing susceptibility Non-ConcussedConcussed mTBI
