Abstract: An all-optical cross-connect switching system provides optical switching that may reduce processing requirements by three orders of magnitude over conventional techniques by associating at least one optical detector with an optical beam steering element. In one embodiment, a first beam steering element, having a reflective surface in optical association with a first optical fiber array, and a second beam steering element, having a reflective surface in optical association with a second optical fiber array, are optically arranged to direct an optical beam from a first optical fiber in the first optical fiber array to a second optical fiber in the second optical fiber array. The optical detector provides information about a first position of the optical beam on the second beam steering element. Based on this information, the angle of the first beam steering element may be adjusted to cause the optical beam to change to a second position on the second beam steering element.

Abstract: A water treatment apparatus including a series of pairs of water filtration cells of an upwelling type. Each cell of each pair has a longitudinally extending water conduit in fluid communication between an upper and a lower end of each cell. The first cell of each pair is a fluidized bed type containing a biologically active media, the water entering a bottom of this cell upwelling through the biologically active media to discharge from a discharge port at or near the top of the first cell. The second cell of each pair has the upper end of its water conduit in fluid communication with the discharge port of the paired first cell and contains media which removes nitrates from the water entering and upwelling through the nitrate removing media for discharge from the second cell.

Abstract: A network design that reduces the number of wavelengths needed to support communications in a Wavelength Division Multiplexing (WDM) network is disclosed. Wavelengths are reused in isolated sub-networks that do not share common network paths, allowing for the reduction in cost of the WDM equipment supporting the communications in the network.
