A protective article formed of a laminate between at least a layer of a liquid-impermeable, vapor-permeable barrier, and at least a layer of a stretchable or elastomeric, nonwoven fiber web is described. The barrier is reinforced at least on one side by the nonwoven fiber web, which remains elastic after being bonded to the barrier layer. The elasticity of both barrier and bonded fiber layers simulate the flexibility of natural or synthetic latex or other polymer films. The nonwoven fiber web includes at least about 75% of individual fibers with a length of over about 1 mm, and the fibers are substantially continuous. A second nonwoven web, a second barrier layer, or both may be attached to the exterior side of the breathable barrier. An elastomeric material coating, such as either a nature or synthetic latex or other polymers, may be applied over at least a portion of the article to provide for additional protection.

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

A knee protection airbag for protecting the knees of a vehicular occupant. The airbag is inflated from a storage position to a deployed position to substantially fill a space between the knees of the occupant when seated on a front seat and an instrument panel. By filling the space between the knees and the instrument panel, injury to the knees, and other body parts, is prevented. Inflation of the airbag is caused by a determination by a crash sensor system of a pending or actual crash involving the vehicle and may include an anticipatory crash sensor which forecasts a crash between the vehicle and another object prior to impact of the vehicle by the other object. In this manner, the airbag is inflated prior to the crash.
