There is provided height rescue apparatus comprising a casing which incorporates a bracket for attachment to a harness. The bracket can be releasably attached to a load element which is attached to a safety line which in turn can be attached to a secure anchorage. There is also a release means in the form of a pull cord for releasing the load element from the bracket after a fall and speed control means for controlling the rate of deployment of an elongate element stored within the casing and thus controlling the descent of a user.

A securing device for securing a person has an axle element attached torque-proofly to a rope drum and rotatably to a support structure, such that, by the axle element, the rope drum is supported rotatably at the support structure. A lever is attached pivotably to the support structure at a deflection point. In a blocking position of the lever, a blocking section is coupled to the rope drum in order to disable a rotation of the rope drum, and in a releasing position of the lever, the blocking section is decoupled from the rope drum and the rope drum is rotatable. A thread section of the lever is coupled to a further thread section of the axle element, such that, upon rotation of the axial element, due to the rotation of the rope drum, the thread section is shifted along the axle element, such that, due to the shifting of the thread section, a rotation of the lever around the deflection point and an adjustment between the blocking position and the releasing position of the lever are effected.

A line retraction device includes a rotatable drum having a line associated therewith, with the line including a first end directly or indirectly attached to the drum and a second end opposite the first end, and at least one retraction member biasing the drum in a first rotational direction of the drum opposite a second rotational direction of the drum, where the drum is configured to: (i) retract the line when the drum moves in the first rotational direction; and (ii) payout the line when the drum moves in the second rotational direction. The device further including a damper assembly configured to provide rotational resistance to the drum in: (i) the first rotational direction of the drum as the line is being retracted; and (ii) the second rotational direction as the line is being paid out.

The current subject matter describes a device and system including one or more movable arms containing one or more magnets that are caused to move relative to a non-ferrous material by motion of the device to generate eddy currents that cause a braking of the device. Devices of this disclosure may include one or more trolleys that moving along a coaster track and which contain braking arms having magnets that move due to inertial force and/or can be controlled by a remote server computer based on information obtained from the one or more trolleys as they move along the coaster track.

An escape system for descending a person from a window is disclosed. The escape system may be mounted above a window through which a person may egress and descend to the ground. The escape system includes a fenestration unit having a frame and a human support embedded into the frame in a stowed position. The human support carries a person during descent. A cable is wound about a shaft supported by the frame. The cable is connected to the human support. The escape system further includes a speed limiting device connected to the shaft that controls the speed of descent.
