Abstract: The invention relates to a compact apparatus and method for the treatment of waste water using ultraviolet radiation. The fluid treatment device comprises:  a fluid inlet (24); a fluid outlet (26); a cylindrical housing (30) extending substantially vertically between the fluid inlet and the fluid outlet; flow control means (50) connected to the fluid outlet; and cooling fins (33) means externally mounted on the cylindrical housing. To ensure a thin laminar flow of fluid along the ultraviolet radiation source, the radial distance between the exterior surface of the ultraviolet radiation source and the interior wall of the cylindrical housing is between 0 and 0.25 inches. The method of treating a fluid utilizing the fluid treatment apparatus comprises the steps of: adjusting a flow control means to accommodate a flow rate of between 1 and 3 imperial gallons per minute; directing a flow of fluid into a fluid inlet;  irradiating the flow of fluid as it passes by an ultraviolet radiation source positioned in a housing; directing the fluid flow through a fluid outlet; and directing the fluid flow to the flow control means. A solenoid valve (44) mounted on the fluid inlet and connected to a delay switch stops the fluid flow into the housing for a predefined period whenever power to the ultraviolet radiation source is re-engaged following a power shutdown.  Utilizing the apparatus and method of the invention, efficient decontamination of human waste for residential or small commercial applications is possible.

Abstract: The present invention provides a system and method with the capacity to compare and analyze keywords of a specific area of study. By the use of the methods of the present invention, some sets of keywords will be seen as "warming up" due to their upward trends, whereas other keywords might be see n as "cooling down" due to their downward trends. Given the accepted fact that  growing areas of research are the ones that are more likely to produce scientific breakthroughs, the system identifies these emerging ("hot") areas  of research would accelerate the scientific advances of their users. Similarly, users will be able to view and shift from non-productive ("cool")  areas of research to productive "hot" areas. The invention involves the utilization of a commercially available database program and provides specif ic keywords associated with the investigated topic. The present invention also provides a method for indexing the keywords using a keyword tree structure database so the data is in the correct format for analysis. This invention also provides a method for analyzing the number of occurrences of keywords along with the analysis of an impact factor associated with the keywords. Th e formatted data then allows the construction of several charts so a user can easily assess the state and forefront of a specified topic.

Title: Dynamically reconfigurable optical amplification element
Inventor: SARGENT EDWARD H
IPC: G02B6/12
Filed: 2002-02-21
Abstract: Abstract of the Disclosure An optical amplifier has a spatially varying absorption spectrum formed in a monolithic InGaAsP structure whose quantum well active structure has modified effective bandgap properties. The effective bandgap properties can be modified by rapid thermal annealing to cause the diffusion of defects from one or two InP defect layers into the quantum well active structure. Multiple such optical amplifiers, having their effective bandgap properties modified to provide different gain spectra, can be monolithically formed in a single semiconductor structure for broadband amplification, in which case their individual gain spectra can be controlled to control the total gain spectrum dynamically.  Alternatively, the optical amplifier can be used in a Mach-Zehnder wavelength converter for broadband wavelength conversion.
