A system to deliver or remove an inflation expandable stent in a body vessel. The system avoids causing damage or embolisms to a body vessel it is traversing by restraining the edges of the stent from scraping against the walls of the body vessel. The edges are restrained by balloon folds, compressive wedging, and angled reflective resistance. In addition the device can also inflate or deflate the balloon more efficiently.

The invention is an inflatable mailer having a liner that can be inflated at the point of use. The liner includes a series of inflatable chambers that are in fluid communication with a common channel. A controlled volume of gas is disposed in the liner. The gas is sufficient to inflate the common channel but is not sufficient to appreciably inflate the inflatable chambers. As a result, the inflatable mailer is in a relatively compact state. The invention includes an apparatus for inflating the mailer. The apparatus includes a nip for moving the controlled volume of gas into the common channel; an inflation nozzle adapted to pierce the inflated common channel and introduce a second portion of gas into the liner until the liner is inflated to a desired level; and a sealing device to seal the inflated liner.

An inflatable structure generally includes a valve formed between a pair of edge portions and an internal edge portion formed of a flexible film such that an enclosed chamber of the inflatable structure substantially envelops the internal edge portion. The valve and remainder of the inflatable structure can be formed from a single piece of flexible film using a method of manufacturing an inflatable structure from a continuous web of flexible film. A corresponding inflation device fills the inflatable structure with air and may do so without requiring heat sealing or contact between the inflatable structure and outlet of the inflation device. The inflation device may include a mechanical registration device which can engage an optional locator aperture in the inflatable structure such as to assist in temporarily locating the outlet of the source of pressurized air proximate to the valve in the inflatable structure.

An input device for providing user input to a computing device includes a seat portion allowing a user to sit on the device.

Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 7 seconds. All coatings, in particular elastomeric, non-silicon coatings, and coated airbags, meeting these criteria are intended to reside within the scope of this invention.

A cushion for protecting a vehicle occupant's head. The cushion inflates and deploys smoothly and is configured so that gas leakage out of the cushion is reduced in order to maintain the inner pressure high for an extended period of time. The cushion includes a protective cushion element and outer shell fabrics superposed on both outer surfaces of the protective cushion element. The cushion element includes a cabin-side base fabric and a window-side base fabric that are sewn together by sewing yarns after being bonded to each other by adhesive. The outer shell fabrics are bonded to the protective cushion element by adhesives. When the protective cushion element is inflated, the outer shell fabrics are tightly stretched over the outer surfaces of the inflated protective cushion element so as to cover depressed portions of the base fabrics.

A flight control system for an airfoil comprises a control surface, a chamber connecting the control surface to the airfoil, and a pneumatic mechanism fluidly connected to the chamber. The chamber may be comprised of at least two cells that may be fluidly separated by a membrane. The pneumatic mechanism is configured to provide differential pressure to the cells in order to alternately increase volume/pressure of the cells to cause deflection of the control surface. The cells may have a stretchable outer surface to allow for changes in the length of the outer surface in response to inflation/deflation of the cells. The outer surface of the cells may be substantially continuous with outer mold lines of the airfoil and of the control surface.

A water sport belt that includes an inflatable bladder that is be secured around the waist of a user to provide a flotation mechanism in an emergency. The inflatable bladder has a number of accordion fold sections that are inflated with an initial amount of air sufficient to provide buoyancy without the need for the user to blow with sufficient force to overcome the elastic walls of the bladder. The water sport belt also includes a water-tight compartment within which a user may safely position items to be kept safe and dry. A card holding structure is provided within the water-tight compartment to prevent damage to credit cards and the like by items such as coins and keys.

A unit is mounted directly on a tank of pressurized gas used to inflate a balloon and includes a supporting bracket having ribbon-accommodating holes defined through one end thereof and a support section on the other end. A ribbon supporting spool is rotatably mounted on the support section and ribbon drawn off the spool is threaded through the ribbon-accommodating holes to be captured in a knot formed in the neck of the balloon after that neck has been drawn around the supporting bracket and formed into a knot. A method of forming a knot in the balloon and capturing the ribbon therein is also disclosed.

The invention discloses a method for modifying wood by filling grafted cell walls with organic monomers and polymerization-filling cell cavities, which relates to a wood modification method. The invention solves the problem of difficulty in simultaneously enhancing mechanical properties and durability of wood in the existing wood modification method. The method comprises the following steps: 1, preparing organic acid anhydride solution; 2, soaking the wood with the organic acid anhydride solution; 3, filling grafted wood cell walls with organic acid anhydride by heating; 4, preparing the organic polymerizable monomer solution; 5, soaking the wood with the organic polymerizable monomer solution; and 6, carrying out polymerization-filling on the wood cell cavities with the monomers by heating. Since organic function micromolecules firstly enter the wood cell walls, the method realizes filling and bonding and eliminates a great deal of hydroxyl groups in the cell walls, thereby enhancing wood durability; and the wood cell cavities are soaked by the organic polymerizable monomers to initiate the polymerization and realize the filling of the cell cavities, so that the wood has higher mechanical properties and durability.

The present invention is directed to an adjustable trailer hitch that provides a suspended connection between a tow vehicle and an attached trailer. The hitch includes a support member that is adapted to be attached to a tow vehicle and a frame having first and second pivots for pivotally support a hitch plate, which is operative to connect to a trailer (e.g., engage a trailer pin). A first air spring has a first end fixedly connected to the support member and a second end fixedly connected to the frame. The air spring permits relative movement between the support member and the frame as well as transmitting towing forces therebetween. The air spring provides a pliable connection that at least partially mechanically isolates the trailer and the vehicle from each other. Instead of acting as a single unit, the vehicle and the trailer act at least partially independently of each other.

Novel airbag coating compositions comprising at least two separate and distinct layers are provided. The first layer (base coat), being in contact with the airbag surface, comprises a composition of at least one coating material which may comprise up to 30% by parts of the total amount of material in the first layer of a silicone resin which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and blocking characteristics to permit effective potential long-term storage and optimum use upon the occurrence of a collision. Such a second layer (topcoat) is preferably a silicone material but may also be selected from the group consisting of homopolymer and coplymer resins based on ethylene, propylene, acrylates, methacrylates, vinyl esters, acrylic acid, methacrylic acid, polyurethanes, polyamides, and inorganic materials such as talc, silica, silicate, calcium carbonate, alumina, and the like. This two-layer system permits excellent strength and blocking properties to prevent undesired adhesion between portions of the target airbag when stored as well as to prevent seam combing at relatively low cost due to the materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.

A balloon has an inflatable main body with a flexible extension. The extension is connected to the main body in such a manner that, when they are inflated, the extension forms a semirigid handle. The balloon therefore requires no separate holder. The balloon can be deflated for storage or shipment and reinflated when desirable or necessary.
