1. An impact awareness device (IAD) to reduce the likelihood of head and vertebral column injuries, the IAD comprising:
an impact switch configured to transition from an open-circuit state to a close-circuit state when a force is exerted on the IAD in a first direction and exceeds a force threshold, the impact switch comprising:
a hub comprising:
a hub base coupled to the hub and having a central axis centered in the hub base, anda conductive body with a body axis coupled to the hub base, the body axis lies along the central axis;a conductive member coupled to the hub base along the central axis;a first wire electrically coupled to the conductive member;a second wire electrically coupled to the conductive body; a headliner configured to couple with a protective headgear, comprising:
a flexible band comprising one or more substrates configured to conform to a headband of the protective headgear, andan electronic circuit coupled to the flexible band and electrically coupled to the switch and wherein when the force threshold is exceeded the electronic circuit transmits an indication signal; and an indicator circuit coupled to the protective headgear and electrically coupled to the electronic circuit, the indicator circuit is configured to provide an indication of the likelihood of a head and a vertebral column injuries when the indicator signal is received. |
