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.

A velocity control device for controlling the velocity of a load on a flexible tension member. The device can include a housing having a housing peripheral surface, with a portion of the housing peripheral surface defining an exit opening. The device can also include a phasing induction brake, the phasing induction brake being adjustable to control flux density in a magnetic circuit.

The invention relates to an abseiling device comprising a bidirectionally rotatable guiding arrangement (25) for guiding a pulling means (26); further comprising a braking mechanism (30) that is coupled to the guiding arrangement (25); a driving means (34; 35) can be connected to the guiding arrangement (25) so as to actuate the guiding arrangement (25). In order to create an abseiling device that prevents an individual from being injured or parts of the abseiling device from being damaged during rescue operations in particular of people, a mechanical torque limiter (33) decouples the driving means (34; 35) and the guiding arrangement (25) or the pulling means (26) when the torque exceeds a certain threshold value.

A personal escape device includes a main housing, a shaft, a magnet housing, and a plurality of magnets. The shaft is rotatably coupled with the main housing and is rotatable about a rotational axis. The magnet housing is positioned in the main housing and is coupled with the shaft such that the magnet housing rotates together with the shaft. The plurality of magnets is coupled with the magnet housing such that the plurality of magnets rotates together with the magnet housing. The stator assembly is coupled with the main housing and surrounds the magnet housing. The stator assembly and the magnet housing are radially spaced from each other to define an air gap therebetween.

A movable cable loop descent system comprises a cable for forming into a loop, a receiver for attachment to a structure having a receiver pulley for engaging the cable loop, a brake assembly, having a drive pulley for being rotated by the cable loop, the brake assembly for slowing a rate of travel of the cable loop and a carriage supporting a load for attachment to the cable loop at a point and for movement between the structure and the ground. A rotor and substantially parallel conductive frame is mounted on an axle through the drive pulley. Magnets on a surface of the rotor and/or the frame induce eddy currents, as they are relatively rotated, which create a rotational braking force controlling descent of the carriage and load. The brake assembly may be removably positioned by a drive-on anchor. The cable is removable and the system may form a kit.

This invention presents a brake control device for high-rise fire rescue systems, notable for its well-thought-out design, high safety standards, and consistent, dependable functionality. The system features two main elements: cable take-up device A on base frame A, and cable take-up device B on base frame B. A connecting device ensures the A transfer spindle of device A and the B transfer spindle of device B rotate in unison. Central to the system is the emergency braking device, comprising a reduction gearbox located under either the A or B cable take-up device. This gearbox is equipped with an input shaft and an output shaft, linked by a gear transmission set. The input shaft connects to the A or B cable take-up device via a transmission member. A magnetic block is affixed to the output shaft's end, and a permanent magnetic crane is positioned at the magnetic block's end.
