The at least one Button configured to accept a knuckle bump may be configured to be adjacent to a user's metacarpophalangeal index finger joint. The at least one Button configured to accept a knuckle bump may be configured to be adjacent to a user's metacarpophalangeal thumb joint. The Takeup Module (300) comprises a Motor Compartment (305), a Takeup Spool Compartment (310), a Takeup Spool Gear Compartment (315), a Takeup Film Window (320), a Motor (325), a Motor Gearbox (330), and at least one Takeup Spool Gear (340). The Takeup Module (300) may further comprise a Takeup Spool Window (350) configured to provide a view of a Takeup Spool (345) within the Takeup Module (300). Also disclosed is a Takeup Spool (500) comprising a Spool Alignment Tab Wheel (505), a Spool Ribbed Shaft (510), a Rib Quarter Section Cutout (515), a Spool Alignment Slot Wheel (525), a Spool Alignment Tab (530), a Spool Alignment Slot (535), a Plurality of Wheel Cutouts (540), and a Plurality of Wheel Slots (545). Also disclosed is a method for maintaining clear vision with goggles comprising receiving a command input via a knuckle bump, transmitting a designated signal to a module comprising a Motor and a Takeup Spool, activating the Motor to cause the Takeup Spool to rotate, and winding a Transparent Film a designated distance over goggles.

A stack of laminated transparent lenses consists of two alternating optically clear materials in intimate contact. The materials are a plastic lens and clear adhesive. The adhesive is uninterrupted. The lens and the adhesive have refraction mismatch of less than 0.2. A tab portion is part of each lens acts as an aid in peeling away the outermost lens after contamination of the lens layer during racing conditions. The lens stack can be mounted to the posts on the face shield or laminated directly to a windshield.

A visor (26) for a helmet (22) comprises: an air delivery element (34) for delivering air to a surface of the visor (26). The air delivery element (34) comprises: at least one inlet (28) for receiving air from an air source (30); and a plurality of outlets (44) through which air is transportable to the surface of the visor (26). The visor (26) may also include a ridge (84) formed adjacent to the plurality of outlets (44) for creating a Coanda effect in air passing through the plurality of outlets (44).

A windshield cleaning system includes a vehicle that has a windshield and a pair of windshield wipers. Each of the windshield wipers includes a wiper blade that is removably coupled to an associated one of the windshield wipers. A pair of abrasive strips is provided. Each of the abrasive strips is attached to the wiper blade of an associated one of the windshield wipers. Thus, each of the abrasive strips frictionally removes debris from the windshield.

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.

A multi-layer visor system for a surgical hood or garment is provided. The system includes a base film layer and one or more removable film layers that are coextruded at high temperature to form a sterile surface between each of the film layers should the surgeon elect to peel away a soiled or splattered removable film layer during the course of a surgical procedure so that an unobstructed view can be maintained. Thus, no separate sterilization step is required in order to sterilize the layers of the visor system. Each of the removable film layers can additionally include a tab having distinctive features in order to enable a wearer to easily distinguish between the tabs in order to make it easier for a wearer to know which tab to pull first to remove the outermost removable film layer. Further, because the tabs are located about the perimeter of the removable films, viewing is not obscured, yet the film layers are held securely in place until easily removed from the underlying removable film layer or base film layer.

Described herein is a self-cleaning visor (1) comprising: a support structure (2) having a see-through portion (2a); an endless transparent film (3); a film drive means (4); and at least one film cleaning means (5); and two fasteners (6). The support structure (2) is releasably attachable to an associated helmet (10) by the two fasteners (6) such that it is tiltable between a raised see-through position (A) and a lowered see-over position (B). The support structure (2) encloses the endless transparent film (3) except for at the see-through portion (2a). The support structure (2) comprises the film drive means (4) and the at least one film cleaning means (5). The support structure (2) supports the endless transparent film (3) to selectively be driven by the film drive means (4) in a continuous loop over the see-through portion (2a) and past the at least one film cleaning means (5).
