A multi-layer cover for an electronic device having one or more of a sensor panel, a proximity sensor, an ambient light sensor, and a display device can include an outer hardcoat, a structural layer, an IR transmissive ink layer, a mask layer, and a backside hardcoat. The backside hardcoat can reduce cover warpage, enable full surface lamination of the cover to the sensor panel, prevent bubbles from forming in transparent windows in the cover, enable a wider range of functional inks to be applied in various layering orders to allow certain types of light to pass through while blocking others, and hide the sensors to provide a seamless, uncluttered visual appearance.

A double chambered transfer mattress is provided capable of partial deflation that that includes a top inflatable mattress and a bottom inflatable mattress that are separated by a common wall from one another. A selectable inlet/outlet valve is arranged for airflow communication between an interior chamber of the bottom inflatable mattress and a source of pressurized air. A one-way valve is positioned through the common wall so as to provide selective air flow communication between the top inflatable mattress and the bottom inflatable mattress so that when the inlet/outlet valve is opened, so as to deflate the bottom inflatable mattress, the one-way valve is actuated so as to prevent deflation of the top inflatable mattress.

A method of forming a via in a low-k dielectric material and without the attendant via poisoning problem, or a dual damascene structure formed in the same dielectric and without the same problem are disclosed. The vertical walls of the via opening are first lined with a low-k protection layer and then covered with a barrier layer in order to prevent outgassing from the low-k dielectric material when copper is deposited into the via opening. In the case of a dual damascene structure, it is sufficient that the hole opening underlying the trench opening is first lined with the low-k protection layer. The resulting via or dual damascene structure is free of poisoned metal and, therefore, more reliable.

The valved ostomy drainage device of the present invention includes a primary conduit which may be inserted into either a colonoscopy or ileostomy. Once inserted, a balloon cuff or collar on the inner aspect of the conduit is inflated which holds the conduit in place in the ostomy. The conduit is anchored on the exterior surface of the patient by a soft, malleable ring which acts as a resilient pad seal and by an anchoring collar which mounts onto the exposed end of the conduit to sandwich the ring against the patient's abdomen. With the collar so mounted the remaining exposed end of the conduit is adapted for sealing by the releasable mounting thereon of a rigid sealing member such as a threaded cap or other means of closure. A flexible one-way valve mounted in the conduit inhibits waste such as bowel contents or stool extruding through the conduit until the cap is removed and the one-way valve biased open by a secondary conduit inserted into the primary conduit and pushed against the one-way valve so as to open the valve.

An occupant protection device that is provided in a door on the side of a vehicle, including an inflator that has an end portion at which a fluid delivery port is formed and delivers a fluid during a vehicle collision, and an expanding body that expands by the fluid fed by the inflator to cover the inside surface of a window provided in the door, with the end portion of the inflator being directly inserted in the expanding body, and the inflator being provided on the side of the door to be mounted to the vehicle body in the longitudinal direction of the vehicle.

A capped micromachined device has a movable micromachined structure in a first hermetic chamber and one or more interconnections in a second hermetic chamber that is hermetically isolated from the first hermetic chamber, and a barrier layer on its cap where the cap faces the first hermetic chamber, such that the first hermetic chamber is isolated from outgassing from the cap.

A lithographic apparatus having a positioning device that facilitates the maintenance of a conditioned environment, is presented. Embodiments of the invention include a combination of a first drive unit and a second drive unit for positioning an object table in a lithographic apparatus. The first drive unit has a first part connected to the object table and a second part connected to a first part of the second drive unit. First and second part of the first drive unit are separated from each other by a wall. Maintaining a conditioned environment surrounding the object is thereby facilitated.

A structural, informative and/or decorative balloon display is comprised of a plurality of connected, inflatable chambers formed by a plurality of die applications to a plurality of layers of film. The largest die application produces a set of seals that encompasses an area smaller than the area encompassed by all such sets of seals. In one preferred embodiment connected chambers have and maintain fluid communication. In another preferred embodiment, connected, inflatable chambers have no fluid communication but have a beginning and an end. In other preferred embodiments fluid communication is terminated after inflation. Other embodiments take advantage of variations of numbers of layers, configurations of layers, and treatment of surfaces to create special balloon forms.

A method of preparing components for use in a vacuum chamber of a lithographic apparatus is disclosed. The method includes coating the component with a non-metallic material. The method may further include treating the coating so as to harden the coating. Preferably, the coating material is a hydrogen silsesquioxane (HSQ), which may be applied via spraying, brushing, or spinning and can be treated by heating or by irradiation with an electron beam. The resulting components strongly reduce outgassing of water and hydrocarbons when subjected to a vacuum environment.

The quality of painted surfaces of polymer composites is improved by first forming an electroless metal coating on the molded surface of the composite and then electroplating a coating of zinc or zinc alloy on the metallized composite surface. The “galvanized” composite surface provides a good base for electrostatic deposition of either liquid or powder paint and the zinc surface prevents the formation of defects in the painted surface during heating of the composite to dry or cure the paint film.
