The present invention discloses an intelligent life-saving system for a high-rise building and an electromechanical device for intelligent fast descent. The life-saving system includes a coverall with short-term high temperature resistance, cushioning and collision resistance, an oxygen-supplying helmet, a high-temperature resistant sling, and an electromechanical device for intelligent fast descent. The electromechanical device includes an intelligent detection and control device, a frame, a follow-up reel, a main shaft, and a fire-proofing and flame-retardant lifeline wound around the follow-up reel. The electromechanical device further includes a permanent magnet generator; brake mechanisms, where the intelligent detection and control device is configured to control the current of an active brake coil in real time based on the descent speed of the fire-proofing and flame-retardant lifeline to adjust a frictional resistance between dynamic brake pads and a stationary brake pad; and a forced braking manipulation.

A self-retracting lanyard system includes a self-retracting lanyard having a main body and a retractable line, a harness connected to the retractable line and wearable by the user of the self-retracting lanyard, and an electronic device disposable on the harness. The electronic device includes an accelerometer, a processor or programmable circuit, and a non-transitory program storage medium on which are stored instructions executable by the processor or programmable circuit to perform operations including receiving a measurement from the accelerometer, comparing the measurement to a threshold, detecting that the user of the self-retracting lanyard has fallen based on a result of the comparing, and instructing a wireless transmitter to transmit a wireless signal in response to the detection that the user has fallen.

Line dispensing devices include a coupling transmission, a retraction mechanism, and a rotor that rotates around a shaft. Rotation of the rotor causes a portion of at least one pivotable member to move into and out of a magnetic field.

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.

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.
