A protective shield includes a rigid base layer, and a flexible outer cushioning layer formed from a flexible film material laminated to an outer surface of the base layer. The outer cushioning layer includes two or more layers of flexible film laminated together via an intermediary adhesive. The protective shield also has a mounting adhesive layer applied on the lower surface of the shield. The mounting adhesive allows the shield to be removably mounted to a display surface, such as a touch screen surface for an electronic device. When the shield is properly mounted to the display surface, the outer layer formed from flexible film material faces away from the display surface. The flexible cushioning layer on the outer surface of the shield allows the shield to protect the display surface such that the display surface can withstand higher levels of impacts without breaking or shattering.

A tear-off capture system includes an eye protector with a base lens. The eye protector has a retention mechanism mounted on one side, and a support mechanism that supports the eye protector on the head of a wearer. A two-tabbed stack of laminated tear-off lenses mounts to the eye protector via an adhesive. The stack mounts so that the first tab of the stack aligns with the first side of the eye protector and the second tab engages with the retention mechanism. Via the second tab and the retention mechanism, released tear-off layers are directed toward the second side of the eye protector away from the base lens. A capturer helps hold the initially released tear-off layer to the eye protector. An exposed tacky surface on each released tear-off helps hold the subsequently removed tear-off layers.
An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.

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.

An automobile or vehicle having a high efficiency solar control system is provided. The automobile may have a painted surface and a film mounted to its exterior side. The film may reflect solar radiation in the near and mid infrared ranges yet allow high transmission of light in the visible range such that the painted panel may be seen. The film may have a layer of silver which reflects the solar radiation in the near and mid infrared ranges. Since the silver is susceptible to oxidation and turns the silver into a black body which absorbs the near and mid infrared radiation, the film may be designed to slow the rate of oxidation of the silver layer to an acceptable level. The silver layer may be sandwiched between the glass which does not allow oxygen to diffuse there through and reach the layer of silver and a stack of sacrificial layers having a certain thickness which slows down the rate of oxygen diffusion to an acceptable level.
