Described herein are braking mechanisms and related methods of use 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.

Described herein is a transmission mechanism and an associated method of use for braking relative movement between members, movement and braking of the members being directed through one or more transmission elements.

Described herein is a transmission mechanism and an associated method of use for braking relative movement between members, movement and braking of the members being directed through one or more transmission elements.

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.

The present disclosure relates to a device for evacuating individuals from a structure during an emergency, comprising: a rotatable drum with a cable suitable length, wound thereon; and a rotation regulator, which is associated with the drum and is arranged to control the drum to limit a rotation speed thereof during unwinding of the cable from the drum. The rotation regulator allows for individuals to escape from a tall structure, regardless of their skill, agility or strength, and even irrespective of whether such individuals are conscious, or not. In an embodiment the device may further comprise at least one additional drum. The combination of the drum and the additional drum allows a plurality of people to escape.
