Abstract: A structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.

Abstract: A ceiling system for a clean room, a clean room ceiling and a method for constructing a ceiling for a clean room are provided. T-shaped beams support the ceiling from a building structure. Channels support composite panels on the bottom side of the T-shaped beams. Each of the channels is attached to the top side of a composite panel and each engages a first or second leg of a T-shaped beam. The channels may be Z-channels.

Abstract: A structural beam and light fixture for a walkable ceiling of a clean room is composed of an elongated channel and a lamp disposed in the elongated channel. The lamp is configured to direct light through the bottom side of the elongated channel. The structural beam and light fixture is attached to adjoining ceiling components and is configured to support a load applied to the adjoining ceiling components. The structural beam and light fixture, combined with other walkable ceiling components, define ceiling top and bottom sides that are flush.

Abstract: Software code for execution in an EDM application in presenting data from one or more data sources to an EDM application user, is generated from the source metadata obtained by analysis of the data sources in accordance with the structural entities of a generic data repository.

Abstract: The specification describes a structure for a vehicle simulator in which realism is maximized. For a simulator in which a trainee can see out, the outer surface is contoured to match the contour of the vehicle being simulated only over that surface which is seen from the trainee's seat. To accomplish this, a first pair of sills are supported above a base surface by a first plurality of ribs, and a second pair of sills are supported above the first pair of sills by a second plurality of ribs. The length of the second ribs space the second sills above the first sills by a distance pre-calculated to cover only the portion of the vehicle that is visible to the trainee.
