ECE 477 – Team 5

Introduction

Riddell - HITS System» Positive:

˃ All sensors stay in place and intact˃ Low profile

» Negative:˃ Only works for helmet based

sports˃ Does not accurately reflect the

accelerations seen on the head

X2Impact – BTX2 Mouth

guard » Positive:

˃ Reflects true acceleration values˃ Stays in place

» Negative:˃ Electronics are placed in mouth˃ “The added equipment made the

mouth guards a little too cumbersome for most players last season. ”

˃ Cannot be used by all sports˃ Not very durable
