Abstract: 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.

Abstract: 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.

Abstract: A scooter is disclosed which positions a center of gravity of a rider toward the front the scooter so that the rider can more easily perform a 180 degree turn trick. Since the rider is positioned closer to the front wheel, it becomes easier for the rider to flip over the handlebars. Fortunately, the scooter reduces a moment arm that defines a deceleration moment to reduce the likelihood that the rider will flip over the front handlebars.

Abstract: A truck assembly for a vehicle such as a skateboard or scooter may have a kingpin about which a hanger rotates. The hanger may be biased toward a caming surface having a depressed configuration by a spring, weight of the rider and also via a centrifugal force created during turning. This aids in dynamically stabilizing the truck assembly and the vehicle to which the truck assembly is mounted based on the particular rider and the maneuver being performed on the vehicle. The caming surface may have a regressive configuration such that the spring compresses at a different rate per degree of rotation of the hanger.

Abstract: A skate truck is disclosed which provides for a wide yaw angle for a hanger, minimal friction during yawing of the hanger, and a suspension that is dynamically stabilized based on a weight of a rider and a turn radius of a vehicle to which the skate truck is mounted. Additionally, a tension of the skate truck can be adjusted by preloading a spring which accommodates a wide weight ranger of riders. The truck may have a hanger supported between two bearings, namely, a sliding bearing system and a thrust bearing. The sliding bearings slide within grooves that define a pivot axis of the hanger. The grooves can also have various customized ramp profiles to provide a different feel during turning of the vehicle.

Abstract: 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.
