This invention generally relates to automated shade systems that employ one or more algorithms to provide appropriate solar protection from direct solar penetration; reduce solar heat gain; reduce radiant surface temperatures; control penetration of the solar ray, optimize the interior natural daylighting of a structure and optimize the efficiency of interior lighting systems. The invention additionally comprises a motorized window covering, radiometers, and a central control system that uses algorithms to optimize the interior lighting of a structure. These algorithms include information such as: geodesic coordinates of a building; solar position; solar angle solar radiation; solar penetration angles; solar intensity; the measured brightness and veiling glare across a surface; time, solar altitude, solar azimuth, detected sky conditions, ASHRAE sky models, sunrise and sunset times, surface orientations of windows, incidence angles of the sun striking windows, window covering positions, minimum BTU load and solar heat gain.

A passive collimating tubular skylight consisting of a radiant energy-collecting aperture, a radiant energy-delivering aperture, and a radiant energy passageway between these two apertures, the passageway having a specularly reflective interior surface and a configuration to improve the collimation of the radiant energy passing therethrough. The skylight can be configured with the radiant energy-collecting aperture located above the roof of a building, oriented to collect sunlight; and equipped with a sealed weatherproof glazing, with the radiant energy-delivering aperture, or luminaire, located at ceiling level within the building, and equipped with a diffusing glazing; and with the reflective tubular light passageway constructed with a larger cross sectional area near the radiant energy-delivering aperture than near the radiant energy-collecting aperture. In complete accord with the second law of thermodynamics, and as proven by experimental results, the new passive collimating tubular skylight provides significant advantages over the prior art, including better solar energy collection, higher throughput optical efficiency, improved radiant energy collimation, enhanced interior illumination levels, and more precise positional control of the interior illumination.

An illuminated sign having front, back and side surfaces. A plurality of first cavities are formed into the back surface of the sign. A plurality of light emitting modules are disposed in the plurality of first cavities. The modules each include a light emitting diode having an emission axis and for producing at least some light output generally parallel to the emission axis, an optical device disposed adjacent the light source having a reflective surface for reflecting the light output in directions that are generally perpendicular to the emission axis, and a guide element disposed adjacent the optical device for coupling the reflected light output into the interior of the sign. The guide element includes a second cavity formed therein in which the optical device is disposed. The front surface is illuminated by the coupled light output from the light emitting modules by reflection and / or diffusion inside the sign.

A powered adjustable seat assembly for a motor vehicle includes a seat, an adjuster mechanism operatively connected to the seat to adjust the seat, a controller operatively connected to the drive motor of the adjuster mechanism to selectively adjust the seat, and a plurality of lights located below the seat and operatively connected to the controller to selectively illuminate the lights upon predetermined conditions. The lights are secured to a moving portion of the adjuster mechanism so that the lights move with the seat. Preferably, one of the lights is positioned to direct illumination in a forward direction toward operator pedals, one of the lights is positioned to direct illumination in a rearward direction toward a rear seat, and one of the lights is positioned to direct light in a lateral direction toward a vehicle door.

Laryngoscope handles including a handle shell having a pair of opposite semi-cylindrical metal or plastic handgrip support members permanently joined together to form a tubular handgrip support and a non-metal sleeve-like handgrip encircling the handgrip support. Rechargeable illumination units for use with laryngoscopes and including a light transmissive end cap diffusely glowing on interior illumination by a least one user indication light source for providing at least one visual user indication regarding the operability of an illumination unit.

A portable, self-contained, black light device that is incorporated into or adaptable to a head gear to be used in combination with fluorescent or phosphorescent material for entertaining effect or promotional purposes. The portable black light device has a housing with a plurality of openings, a plurality of UV LEDs protruding from each opening and a power source within the housing for energizing the UV LEDs. With the portable black light device incorporated or adaptable to the visor or brim of a head gear, and in combination with fluorescent paint or make up on a wearer's face or fluorescent decorative element, cause the fluorescent paint to glow as if internally lit, providing an effective entertainment or advertisement.
