Abstract:
1. A child safety barrier, comprising: a passageway barrier assembly for a passageway, said passageway having first and second opposed sides, wherein said barrier assembly comprises: a first correlated magnet attachable to a structural element on the first side of said passageway and a barrier comprising a second correlated magnet, said barrier being attachable to a second structural element on the second side of the passageway opposing said first side and positionable into a closed state in which the barrier spans across the passageway and an open state in which the barrier does not span across the passageway; and wherein: said first correlated magnet is capable of being aligned with said second correlated magnet such that said first and second correlated magnets produce an attractive force that holds said first and second magnets together and secures said barrier in said closed position; said attractive force is a peak spatial force of a spatial force function; said spatial force function corresponds to a code modulo defined by a code that defines said peak spatial force and a plurality of off peak spatial forces; and said plurality of off peak spatial forces have a largest off peak spatial force that is less than half of the peak spatial force.
