The present subject matter is an improved skylight employing four key elements to achieve its twin objectives of improved low sun-angle light collection and reduced high sun angle light and heat collection: (1) a transparent truncated pyramid-shaped dome, (2) two horizon-facing parabolic reflectors, (3) a collimating curb, and (4) a dual-pane diffuser assembly.

A solar shading panel for use in north and south sides of a building is described, where the solar shading panel is effective in preventing against direct sunlight partially or throughout the year without angle adjusting equipment, while allowing building occupants to perceive external views at all times. The solar shading panel includes a frame and an opaque panel with spacing perforates attached to hollow cylinders. An upper portion of the hollow cylinders can be configured to protect against direct light and a lower portion of the hollow cylinders can be configured to receive and reflect natural light into the building.

A versatile length, deep well skylight, with supplementary light emitting diodes, that are powered by a back-up battery, charged by the sun. This green energy unit is self-contained and saves the cost of primary power. It is dual domed which attracts solar rays which are then reflected through a mirror polished aluminum interior. The light is then diffused through a lower lens to produce cool, even light in the structure interior.

The rim of the upper lens houses multiple solar panels which collect the solar energy for the battery back-up. The battery back-up provides the energy to the light emitting diodes through the inverter which converts the direct current electricity to alternating current electricity and then through the driver which in turn produces light from the light emitting diodes.

Light which is produced directly from the sun and/or indirectly through the light emitting diodes is then reflected through the deep well, mirror polished aluminum interior to the diffuser. The lower lens or diffuser spreads the light evenly across the interior of the structure. The unit is thermal neutral and designed for leak-proof installation. It is also designed for simple, easy maintenance with snap in parts and a hinged lower lens.

A portable inflatable golf studio including an arcuate shaped roof panel, first and second side panels, a floor panel, a front panel, a back panel, a projector screen, a projector, and a tracking system. The first and second side panels are positioned parallel from one another and are attached to the arcuate shaped roof panel, wherein one of the first and second side panels defines a cavity configured to receive a television monitor. The floor panel configured to connect the first and second side panels to one another. The front panel removable attached to the arcuate shaped roof panel and the first and second side panels. The back panel positioned parallel to the front panel and attached to the arcuate shaped roof panel and the first and second side panels. Each panel includes one or more of inflatable sections.

The present subject matter comprises a simple, passive skylight dome with relatively tall partially vertical sides comprising partially transparent material which diffuses the transmitted light, and a mostly opaque sun shade near the top of the relatively tall partially vertical sides. The partially vertical sides are able to better intercept sunlight from low sun elevation angles than conventional horizontal skylights. The mostly opaque sun shade is able to block sunlight from high sun elevation angles to prevent such sunlight from entering the building below the dome. By enhancing the collection of low-sun-elevation-angle light, the subject matter improves the daylight performance of the skylight early and late in the day, and all day in the winter months. By reducing the collection of high-sun-elevation-angle light, the subject matter reduces the solar heat gain near solar noon in the summer months, thereby reducing air conditioning loads and related costs.

The present disclosed subject matter is a curved reflective skylight curb insert which intercepts and reflects low sun elevation angle sunlight, thereby minimizing glare and providing more uniform illumination within the building below.

The present invention is directed generally to a new flat or A-frame pop-up canopy, shelter, cover, and/or awning, to the integration of skylights and electrical lights systems, to clocks and watches that can record a persons preferred alarm voice or video, winter gloves made to look like or with caricatures formed with or on them, digital radio and TV systems with a method of overcoming lost signal interruptions, and a single vent HVAC temperature control systems. Each of these approaches make life easier and/or more fun for people.

An improved skylight is described that includes a plurality of compound parabolic concentrator like structures into the functional layers of the skylight to provide more visual light transmittance with less solar heat gainmore light with less heatto wider areas of building interiors.

The present disclosure relates to a roof window (1), wherein the roof window comprises a frame (2) supporting a glass unit (3) comprising an first outer major surface (9a) for facing the interior of a building, and a second outer major surface (9b) for facing away from the interior of a building when the window is installed in an aperture of a building. The frame (2) comprises one or more frame profiles (2a-2d) that is/are hollow and comprises an interior frame profile space (7) enclosed by exterior frame profile walls (5a-5f). A frame reinforcement profile (8) is arranged in the interior frame profile space (7), and the thermal conductivity coefficient (k.sub.rp) of the material of the reinforcement profile (8) is higher than the thermal conductivity coefficient (k.sub.sw) of the material of the exterior frame walls (5a-5f). The reinforcement profile (8) comprises a wall part (8w) extending in a direction away from a first region located proximate a first plane (P1) comprising the first outer major surface (9a) of the glass unit (3), and moreover extends in the interior frame profile space (7) in a direction away from a second plane (P2), so that the interior space (7) is split into a first space part (7a) located at a first side of the reinforcement profile, and a second space part (7b) located at a second side of the reinforcement profile. The second plane (P2) is perpendicular to the first plane (P1), extends parallel to the longitudinal direction of the frame profile, and touches a part of an exterior surface (6a1) of a first exterior wall (5a) of the frame profile that faces and is proximate the frame opening (4).
