A system for predicting and warning of impacts includes a sensor located remote from a user and configured to acquire user data regarding motion of the user and object data regarding motion of the object; and a processing circuit configured to predict a potential impact between the user and the object based on the user data and the object data; and control operation of a user-wearable warning device to provide a warning output to the user in advance of a predicted time of the potential impact.

System and method for impact prediction and proximity warning

A penalty allocation system includes a processing circuit configured to receive first data from a first player-worn sensor regarding a first player involved in an impact, receive second data from a second player-worn sensor regarding a second player involved in the impact, identify one of the first player and the second player as an at-fault player in connection with the impact based on the first data and the second data, and determine a penalty for the at-fault player based on the first data and the second data.

Systems and methods for determining penalties

An airbag inflation system includes a processing circuit configured to receive object data including positional data regarding an object and at least one of a relative velocity and a relative acceleration of the object relative to a first helmet and control operation of an inflation device to inflate an airbag based on the object data.

Helmet airbag system

A helmet with an airbag assembly coupled to the shell of the helmet. The airbag assembly includes an airbag and an inflation device. The inflation device is configured to at least partially inflate the airbag upon deployment of the airbag assembly. The helmet also includes a processing circuit disposed at least partially within the shell. The processing circuit is configured to receive helmet data regarding a second helmet, transmit deployment data regarding inflation of the airbag assembly, and control operation of the inflation device to inflate the airbag based on the helmet data.
