Approximately 100,000 concussions were diagnosed in Canadian hospitals in 2010 and approximately two-thirds were sports related. A Canadian electronics manufacturing company, Artaflex (Markham, Ontario Canada), have manufactured a tri-axial linear accelerometer and gyroscope system that fits within athlete's helmets; it is capable of measuring the linear and rotational accelerations when an athlete receives an impact while participating in sports (Gforcetracker - GFT). This company is interested in receiving assistance developing an analysis approach that would use the GFT signals to predict the acceleration of the football player's head during impacts. We propose to concurrently measure head accelerations using an anthropomorphic test dummy (crash test dummy headform) and GFT data for a series of controlled impacts using a linear impactor resulting in linear and angular accelerations. Our analysis will focus on modelling the relationship between the GFT outputs and the accelerations of the head.

2010年，在加拿大医院被诊断出大约100,000次脑震荡，大约三分之二与体育有关。一家加拿大电子制造公司Artaflex（加拿大安大略省Markham）生产了适合运动员头盔内的三轴线性加速度计和陀螺仪系统。当运动员在参加运动时受到影响时，它能够测量线性和旋转加速度（GFORCETRACKER -GFT）。该公司有兴趣获得协助开发一种分析方法，该方法将使用GFT信号来预测撞击期间足球运动员头部的加速。我们建议使用拟人化测试虚拟（崩溃测试假发）和GFT数据同时测量头部加速度，以使用线性影响器进行一系列受控撞击，从而导致线性和角度加速度。我们的分析将着重于建模GFT输出与头部加速度之间的关系。
