Claim 16:
17. A fall protection apparatus comprising:
a primary system configured to undergo motion when a force is imposed on the primary system, the primary system comprising a moving member and at least one further member linked to the moving member, the at least one further member acting as a first motion characteristic sensor that senses at least two motion characteristics of the primary system; and
a secondary system;
wherein, below a threshold of sensed motion characteristics, the primary system and secondary system remain kinematically independent of one another, and, above the threshold of sensed motion characteristics, the at least one further member moves to cause direct engagement between the primary system and the secondary system, thereby slowing or stopping independent kinematic motion between the primary system and the secondary system;
wherein the at least one further member of the primary system comprises a pawl sensing primary system velocity and an inertial mass sensing primary system acceleration, the pawl and inertial mass retained together via a bias element, wherein the moving member of the primary system comprises a rotatable disk rotatably movable about a central axis, wherein, in use, the primary system undergoes motion according to a kinematic relationship when a force is imposed on the rotatable disk, the pawl having a centripetal force acting thereon when the rotatable disk spins, this centripetal force acting against the bias element;
wherein the secondary system is kinematically independent to and surrounds at least part of the primary system, the secondary system comprising a latch member.
