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 Riddell - US Patent #1
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… X2Impact- Pending Patent #1
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. X2Impact- Pending Patent #2
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 Analysis of Patent Liability
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?) Analysis of Patent Liability
Non-Concussed mTBI Concussed 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 <Player, Impact # in last month, Time from last impact, Location, Peak Force, Decay Time, Angle of Rotation, % Change in MRI morphology, ABET rating, IMPACT test score> • 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 Answer – New Prediction Method
