Abstract: A penalty allocation system includes a first equipment, a second equipment, and a processing circuit. The first equipment is configured to be worn by a first player. The first equipment includes a signal-carrying material configured to carry a signal. The second equipment is configured to be worn by a second player. The second equipment includes a sensor configured to acquire signal data from the signal in response to the sensor of the second equipment directly engaging the signal-carrying material during an impact between the first equipment and the second equipment. The processing circuit is configured to determine at least one of a penalty and a reward for a recipient regarding the impact between the first player and the second player based on the signal data. The recipient includes at least one of the first player and the second player.
