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 multitouch-capable touchscreen is realized in that a large number of pressure sensors are attached under a flexible surface and thus both the pressure distribution and also the deformation of the surface is measured. Local pressure maxima occur due to the flexibility of the surface material with associated deformation on contact. As several local pressure maxima can exist, it is thus also possible to identify a plurality of contacts simultaneously. It is possible from the strength of pressure and pressure distribution to determine the force that is used for pressing such that this information can also be used in the user interface. Such sensors can be produced very efficiently and inexpensively by printing an ink that changes its resistance under pressure onto PCB tracks designed as sensor surfaces. The PCB tracks and the sensor surfaces can also be printed out using an ink with as low a resistance as possible.

A vaso-occlusive device includes inner, intermediate, and outer elements arranged coaxially. The inner element is a filamentous element, preferably a microcoil. The intermediate element is made of a non-metallic material, preferably an expansile polymer. The outer element is substantially non-expansile and defines at least one gap or opening through which the intermediate element is exposed. In a preferred embodiment, when the intermediate element is expanded, it protrudes through the at least one gap or opening in the outer element and assumes a configuration with an undulating, convexly-curved outer surface defining a chain of arcuate segments, each having a diameter significantly greater than the diameter of the outer element. The expanded configuration of the intermediate element minimizes friction when the device is deployed through a microcatheter, thereby reducing the likelihood of buckling while maintaining excellent flexibility. The result is a device with enhanced pushability and trackability when deployed through a microcatheter.
