20100138164	PHYSICAL GEOLOCATION SYSTEM - A real-time system for determining the geographic movements of an individual or object by sampling particulates contained thereon. The system includes particle collection, sample preparations, and sample analysis using three primary modes of detecting certain particulates. The first mode involves the imaging of pollen, spores, or other biological material which are visible through a light microscope when properly stained or prepared. The second mode involves the use of real-time polymerase chain reaction to amplify and detect target nucleic acid sequences. The third mode involves the use of X-ray diffraction to identify mineral particles. The results from any mode, or any combination of modes, are analyzed by comparison to a reference database containing geographic information and the results are compiled by a controller for visual display.	06-03-2010

20110158741	Nodal Member For A Frame Structure Nodal Assembly - A nodal assembly, such as for a frame structure, includes a nodal member which has a fastening flange for connecting to a hollow frame member. An adhesive channel runs helically around an outer surface of the fastening flange, substantially transversely to a pushing-on direction of the frame member. The frame member is pushed onto the flange, and an adhesive is injecting into the adhesive channel via an adhesive injection opening formed in the frame member.	06-30-2011

20110232482	Moisture Mitigation in PSA Air Fractionation - Disclosed is a method for subjecting feed air to fractionation for recovery of a product oxygen fraction therefrom in a pressure swing adsorption (PSA) process utilizing a nitrogen-selective adsorbent (“NSA”) that is sensitive to water. The PSA process includes the steps of feed pressurization, production, equalization, and blowdown. The improvement to this PSA process commences with placing a bed of pre-treatment adsorbent between feed air and a bed of NSA. Next, a controllable valve is interposed between the pre-treatment adsorbent bed and the NSA bed. Finally, the controllable valve is kept closed during the steps of production, equalization, and when the process is idle. An advantageous NSA is LiX zeolite, Li-LSX zeolite, CaX zeolite, and similar adsorbents, particularly highly hydrophilic zeolites. Another feature of the disclosed PSA cycle is that the pre-treatment adsorbent bed blows-down while the NSA bed equalizes.	09-29-2011
