Abstract: An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable. The trolley comprises front and back wheels conjoined via left and right trolley plates and a handle bar. Front and back hand brake levers are mounted onto the handle bar. When front and back hand brake levers are squeezed by the rider, they create a constricting force which applies friction to the suspended cable via brake pads. This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along the suspended cable. The rider is able to quickly and easily remove the trolley from the suspended cable and transport it to another.
Abstract: The lever, wheel and axle, pulley, wedge, screw, and inclined plane are the six Simple Machines of the Classical era. Over 2000 years ago a man from Syracuse used them to create a way to move water against the pull of gravity. The Archimedes' screw is still a standard for simple efficiency. In homage to those early machines and the dreamers who built them, the Human Flying Apparatus provides a carriage, wheels and an axle, a harness, and a braking and steering system and, in specific embodiments, thrusters, all suspended from a single rail, which allows a human being to soar in simulated flight that is safe, sustained, and suitable for all skill levels. “For once you have tasted flight, you will walk the Earth with your eyes turned skyward, for there you have been, and there you long to return.

A magnetic field may be induced by rotational movement of the first or second moving element relative to at least one conducting plate in a direction to oppose acceleration of at least one drive assembly as it rotationally engages the object.
Abstract: An embodiment of the invention is directed to a system having a pulley attached to a building. A closed loop of cable is installed around the pulley. The loop is of sufficient length so as to reach, when deployed outside of the building, below the pulley to where emergency personnel gather in an area next to a base of the building (when responding to a disaster situation in the building). A winch around which the loop is to be operatively installed is located in the area next to the base. Other embodiments are also described and claimed.
Abstract: A magnetic descent control device is disclosed. The device comprises an input shaft affixed to a rotating driven sheave acting as a drive assembly, which grips a cable guiding the descent path of a body carrying cage. The input shaft has a shoulder upon which rests a rotor. The rotor is encased within a front and back enclosure of conductive material. Disposed along at least one surface of the rotor and/or at least one of the conductors, is a series of magnets such that rotation of the rotor relative to the conductors creates relative motion between the magnets' magnetic field and the conductor inducing eddy currents in the conductor that oppose the magnetic field creating a rotational braking force. As a result, very precise and/or controllable descent may be obtained over a broad range of descent angles and/or distances with little or no mechanical wear or risk of overheating. Preferably, the sheave gripping the cable may have a circumferential groove to better improve traction and grip of the cable.
Abstract: A device for the safe descent of people or cargo along the cable, for example, for the salvation of people in case of fire in high-rise building. To provide the salvation of a few people during the same rescue operation, the device ensures movement along the cable in both directions, downwards and upwards. There is no need for any extensive preparation before using the device. The cable, with or without a handing device, is fixed in the point of lowering, dropped downwards with the weight and then is reeled three times upon the contact disk. Such connection ensures moving the contact disk along the cable without sliding.

Up to 1440 persons could be evacuated in one hour. More could be evacuated by using more cables such as one on each corner of the building.
Abstract: The system for safe descent of people or cargoes, for example for rescuing people in case fire in high-rise buildings consists of a device for control movement along the cable, the cable itself and a connection between them. There is no need for any serious preparation before using the system: the cable by means of hanging device or without them is dropped downwards or the cable is discharged from the cross bow to the lower object where the harpoon fixes itself. The control over the speed of the descent is performed automatically by means of electric frictional brake. Required energy is used from energy weight of descending object. The rotor of a generator of direct current and the axis of the movable disk of the brake is connected with the axis of the contact disk through the reducer. Three revolutions of the cable are reeled upon this contact disk.
