Described herein is a system, method of use and Self Retracting Lifeline (SRL) apparatus using a system that governs a dynamic response between members causing a halt in relative motion between the members. Magnetic interactions, eddy current drag forces and centrifugal and/or inertial forces may provide various mechanisms of governing movement.

Latch activation between members

Described herein are eddy current brakes and associated methods of their use, particularly configurations that have a kinematic relationship with at least two rotational degrees of freedom used to tune operation of the brake or apparatus in which the brake is located.

Eddy current brake configurations

Described herein are braking mechanisms and related methods of using eddy current interactions to resist relative movement between members, the magnetic flux about an eddy current region being modified beyond an inherent drag effect resulting from a simple magnetic pole arrangement.

Methods of altering eddy current interactions

Described herein is an assembly and methods of use thereof for controlling or governing the relative speed of motion between the assembly parts via eddy current formation. The assembly and methods also may minimize the number of parts required and may minimize the number of moving parts thereby increasing the mechanical durability of the assembly compared to art designs that may have more moving parts and greater part complexity.

Assembly to control or govern relative speed of movement between parts

Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.

Latching devices

Described herein is an apparatus and method to convey an object through the air in a controlled and repeatable manner. The apparatus may comprise an object attached to at least one resilient member, the resilient member or members constraining object movement in a substantially vertical y-axis direction. The apparatus may also comprise at least one support member coupled to the at least one resilient member, and the support member or members constrain object movement in a substantially horizontal x-axis direction. In use, the resilient member is energised, movement initiated, and object movement then occurs in an x-axis and a y-axis direction, the movement path substantially governed by the resilient member(s) and the support member(s). The apparatus and method may allow the object to experience a variety of movement sensations, one being the feeling of flight or gliding.
