Patent ID: 8382685

Claim:
An electronic safety device in a sport-specific helmet for protecting the head of a first participant of an impact-sport, when the head is tilted beyond a threshold unsafe position and comprising: (a) a position sensor in the helmet for sensing when the position of the head of the first participant is tilted beyond a threshold unsafe position and providing a signal indicative of the sensed unsafe head position; (b) a processor in the helmet connected to the position sensor for receiving the signal indicative of the sensed head position, the processor incorporating means operable to determine if the head of the first participant has been in the unsafe position for a first continuous duration of time, and further being operable to generate a signal qualifying the determination, after said first continuous duration of time ; and, (c) an indicator in the helmet connected to the processor for receiving the signal qualifying the determination, and subsequently indicating that the head of the first participant is in an unsafe position; (d) processor further incorporating means operable to determine when the head of the first participant has been in an unsafe position for a second continuous duration of time, which is longer than the first continuous duration of time; and, (e) said processor being operative to generate a stop signal to said indicator indicating that said second duration of time is longer than said first duration of time , and stopping said indicator from indicating that the head has been in the unsafe position for the second continuous duration of time.
