Abstract: An apparatus, method and system for assembling lighting fixtures where reflective inserts are installed into a reflector frame to create a reflective surface for the fixture. According to one aspect of the method, some type of worker-perceivable indication prompts a worker as to which reflective insert should be installed at which mounting location on the reflector frame. The worker does not have to guess or translate written instructions. The method can be used sequentially to provide such assistance for each of a plurality of reflective inserts for a plurality of mounting locations. The method is particularly helpful if the reflective inserts are not identical for each mounting location. According to one aspect of an apparatus according to the invention, a reflector frame is removably mounted to a machine that holds the reflector frame in an indexed position.

Abstract: A method of matching the operations of a primary computer and a backup computer for providing a substitute in the event of a failure of the primary computer is described. The method comprises assigning a unique sequence number to each of a plurality of requests in the order in which the requests are received and are to be executed on the primary computer, transferring the unique sequence numbers to the backup computer, and using the unique sequence numbers to order corresponding ones of the same plurality of requests also received at the backup computer such that the requests can be executed on the second computer in the same order as that on the first computer. In this manner, the status of the primary and backup computers can be matched in real-time so that, if the primary computer fails, the backup computer can immediately take the place of the primary computer.

The present invention includes devices or components that include, but are not limited to high efficiency switchable gratings. In one embodiment of the invention, each of the “base” gratings have substantially identical spatial frequencies and each of the “vertex” gratings have substantially identical spacial frequencies. However, the “vertex” gratings have higher grating frequencies than the “base” gratings. In another embodiment of the invention, the “base” and “vertex” gratings have substantially the same grating frequencies.

Abstract: Methods and system for chromatic dispersion compensation in disperser-combiner optical systems. The chromatic dispersion in disperser-combiner optical systems is substantially compensated by, after separating the input optical radiation into distinct chromatic components, propagating the distinct chromatic components through the optical system so that a pre-selected relationship between optical path lengths through the optical systems of the distinct chromatic components is obtained, where the pre-selected relationship substantially compensates the chromatic dispersion. The pre-selected relationship is obtained by reflecting the distinct chromatic components from a suitably placed and shaped pixellated optical volume reflector. After propagating through the optical system, the distinct chromatic components are recombined.

Abstract: An apparatus and method for providing a temporary spread footing for supporting a variety of different vertically extending structures. The apparatus includes a frame with a top and bottom. The frame can have a substantial space or void in between the top and bottom into which weights or devices can be placed. A connection on top of the base removably connects to the structure to be supported. Outriggers could also be used to substantially increase the overturning moment resistance of the base. The outriggers can be removable or retractable so that for transportation, the base has minimum dimensions. The method includes pre-determining the needed weight and overturning moment resistance for a particular application and transporting the base to the site and thereafter adding weight and adjusting outriggers to match the pre-determined needed overturning moment resistance.
