An electric magnetic resistance control structure for an exercise machine includes a base; a flywheel, pivotally connected to the base through a rotating shaft, the rotating shaft defining an axial direction, the flywheel, a non-magnetically sensitive layer being coupled to a circumference of the flywheel; a power unit, fixed to the base; a magnetic resistance unit, including a coupling portion corresponding to an arc of the non-magnetically sensitive layer, at least one magnetic member being provided on the coupling portion and kept at a distance from the non-magnetically sensitive layer to generate a magnetic resistance effect; a control unit, configured to control a current applied to the power unit to drive the magnetic resistance unit to move along the axial direction, thereby changing an overlapping area of the magnetic member and the non-magnetically sensitive layer in the axial direction, so as to adjust a magnetic resistance of the flywheel.

Tuning of a kinematic relationship between members

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetic flux interaction that, in effect, may provide a tunable resistance to movement, changing the rate of relative movement between the members. In one embodiment, the device comprises a first member in a kinematic relationship with at least one further member to form a system. The system moves within a limited range of motion and the system interacts when an external energizing force is imposed on the system causing the members to respond due to their kinematic and dynamic characteristics and thereby creating relative motion between the members. The trigger member is coupled to the at least the first member and moves in response to a pre-determined system movement. When the trigger member moves, the trigger member imposes a braking action on the system or a member or members thereof. The speed and/or intensity of the braking action imposed by the trigger member on the system or a member or members thereof is controlled by the trigger member rate of movement. This rate of movement is in turn governed by a magnetic flux interaction between the trigger member and the at least one first member causing formation of a magnetically induced eddy current force between the parts.

MAGNET ASSEMBLIES OF ELECTROMECHANICAL ACTUATORS FOR ELEVATOR SYSTEMS HAVING ENCAPSULATED SWITCH

Magnet assemblies of electromechanical assemblies for elevator systems are described. The magnet assemblies include a magnet, at least one rail engagement block, and an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material. A target extension is formed from the material of the encapsulating body and extends away from the magnet and the at least one rail engagement block. A proximity switch target is held within the target extension for detection by a proximity switch.

Latch activation between members

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.
