A CHMSL (16) or other lighting system feature of an automobile (10) includes a feature for presenting personal expressions in the form of words or symbols but is automatically deactivated when the regular vehicle lighting system is in use. The personal expression is fixed in a tangible medium by way of phosphor-coated indicia (34) placed within a UV impervious housing (18). A secondary UV light source (36) selectively energizes the phosphor-coated indicia (34) so that the irradiated material glows and is visible through a light transmissive screen (20). The light transmissive screen (20) is provided with a UV blocking agent so that harmful UV rays do not escape the housing (18). The phosphor-coated indicia (34) can be mounted on a removable transparent plate (30), on light dispersion optics (24, 26), or on the inner face of the light transmissive screen (20). A control circuit (42″) manages the primary light source (22) and the secondary UV light source (36) so that only one of the light sources can be energized at any one time.

The present invention discloses the utilization of zeolites for controlled-release of cosmetic and pharmaceutical compositions by nano-diffusion technology. The treatment and protection of skin surface requires that certain compositions be delivered to the skin surface and allowed to remain on the skin surface for as long as possible before such ingredients are absorbed into deeper layers of skin and carried into the bloodstream. Zeolites do not absorb into the skin, which is useful for topical delivery of cosmetic and pharmaceutical compositions, for example antiaging, anti-wrinkle, antioxidants, skin whitening, acne treatment, rosacea treatment, sun screens, UV blocks, anesthetics, skin soothers, anti-irritants, anti-inflammatory agents, vitamins, hormones, and such that are electronically attached to the outer surfaces of such zeolites and are released to the outer surface of skin by a diffusion-controlled thermodynamic process.

The invention relates to the field of printed security documents and, more particularly, to security documents and methods of making security documents bearing enhanced security features. The security documents may include identification documents or any other known documents of value.

When both face and back sides are simultaneously illuminated with ultraviolet light, the patterns printed on both sides of the ultraviolet blocking agent within the area of the transparent window become visible at the same time.

A UV air cleaning and disinfecting system has an enclosed chassis with an inlet / outlet surface panel on one planar side thereof, and the chassis is mounted in the space behind a drop ceiling with its surface panel coplanar with the ceiling surface and facing into the room space. The surface panel has a pair of inlet vent arrays on opposite longitudinal sides of the surface panel from each other, and a pair of outlet vent arrays on opposite latitudinal sides of the surface panel from each other. Arranged in the chassis are an air blower unit and an array of UV lamps. The positioning of the inlet and outlet vent arrays establish four mutually circulating air streams in a four-leaf-clover pattern in the room space, which obtains a high-efficiency throughput of air handled by the system.

The system's chassis is dimensioned to fit on ceiling rails spaced at standard 4 foot length and 2 foot width intervals. The system can provide 99% or higher inactivation of pathogens in the air with 2 to 7 or more air changes per hour for standard sized rooms.
