Abstract: A parachute having two air-balloon sections within the upper portion of the main canopy. Each of these air-balloon sections is isolated from the main canopy and from the other air-balloon section. Both air-balloon sections are filled with lighter-than-air gas, for example helium, and thus provide an active lift to the parachute. At least one inflating air valve and deflating air valve are provided at each air-balloon section for inflating and deflating them. The sections are filled either manually, in accordance with a predetermined scheme, by the parachutist himself or automatically after the main canopy opens up. Gas is preferably contained within two gas tanks, one for each section, located on the back of the parachutist on both sides of the backpack, containing the parachute and attached to the harness worn by the user. The provided parachute may be used as safety equipment, a sport or recreational device, and/or as a mode of transportation allowing a prolonged floating in the air.

Abstract: A clearing system for external mirrors and side windows of a vehicle provides a flow of compressed warm air to an air distribution unit equipped with a number of openings to direct the flow of air towards the surface of the mirror or a side window. In one embodiment, the air compressor, the air heater and an optional air filter are located in the housing of the external mirror. In another embodiment, a supplemental air distribution unit is provided to be mounted along the door of the vehicle to increase the coverage area of the side window. In a further embodiment of the invention, the system is made adjustable for allowing the most appropriate angle for the air openings towards the mirror and the side window. Provisions are also made to use the system for newly designed vehicles and incorporate the elements of the system into the design of the vehicle door. Alternately, an add-on elements are described to allow existing vehicles to benefit from the system.
