Abstract: Example aspects of the present disclosure allow an end user to determine how a finite amount of a measurable resource is allocated among the various balanceable and feature zones of control defined within the overall measurable resource control system, and which can be implemented using a wide variety of hardware/components. A control program allows the end user unprecedented flexibility and control to determine how the resource is allocated among the various zones or types of resource use within the application, as long as the total resource consumed does not exceed the predetermined/predefined total maximum allowable resource. When the end user adjusts a feature or balanceable zone level, the control program adjusts the other balanceable zones based on predefined algorithms, when necessary, to ensure that the maximum measurable resource consumed by the system does not exceed the predetermined/predefined overall maximum resource allocation.

Abstract: The invention offers an improvement in lighting control systems by providing a simplified power switching control system (i.e., using direct AC line voltage or DC current power switches instead of low voltage switches that control higher-current-capable relays) that controls the power to the power supplies that drive the light producing devices in a plurality of luminaires or lighting fixtures in a given installation. The lighting control system facilitates multiple modes of lighting configurations while requiring fewer switches that the prior art and also being easier to operate. The system supports the simultaneous use of multiple lighting technologies. Other embodiments showing extensions to the invention are also disclosed.

Abstract: The invention provides an improvement in suspendable structures and assemblies such as linear lighting fixtures/luminaires that are intended to be suspended from ceilings or other such structures. The housings of the assemblies are designed to include at least one structural member with prestressing in at least along a major longitudinal axis over at least a portion of the length of the member. Once the structural member is incorporated into the housing and overall assembly, the housing and/or assembly is substantially planar and uniform once the assembly is suspended, making the assembly both stronger and more aesthetically appealing. Other embodiments showing extensions to the invention are also disclosed.

Abstract: An indirect fluorescent luminaire with planar specular reflectors arranged in such a manner as to project its maximum intensity approximately at 130.degree. above nadir to optimize the uniformity of ceiling luminance. The lamps are stacked vertically to further minimize the vertical projection of intensity and enhance the lateral projection. The fixture may be suspended at distances of 12 inches or less from the ceiling without causing excessive luminance on the ceiling above the luminaire or excessive luminance ratios between the brightest area directly over the fixture and a point midway between them.
