Metal And Wood Composite Framing Members For Residential And Light Commercial Construction (Div A), Armin Rudd
Metal And Wood Composite Framing Members For Residential And Light Commercial Construction (Div A), Armin Rudd
UCF Patents
Metal and wood composites are used to create framing members (studs and tracks, joists and bands, rafters, headers and the like.) for lightweight construction. Metal is utilized for its high strength, resistance to rot insects, cost stability, and potentially lower cost through recycling. Metal that can be used includes roll formed steel approximately 18-22 gauge. Wood is used primarily for its lower thermal conductivity and availability. The metal components form the primary structure while wood either solid or other engineered wood, provides some structure and a thermal break. The invention connects J-shaped or triangular shaped metal forms to wood sections. …
Pre-Stressed Frp-Concrete Composite Structural Members, Amir Mirmiran, Mohsen Shahawy
Pre-Stressed Frp-Concrete Composite Structural Members, Amir Mirmiran, Mohsen Shahawy
UCF Patents
Fiber reinforced plastic FRP formed about concrete piles and columns. The FRP components generally includes an exterior shell and an interior protruding portions. The concrete filled FRP tubes are enhanced by prestressing the concrete core, thereby increasing the bond with the tube and placing the tube in an active hoop tension. The prestressing can be developed by either post-tensioning a series of strands(or tendons) that are placed inside the core, or by using expansive core materials which do expand upon curing and will therefore impose an active pressure on the confining tube. The bond can be developed by either internal …
Heat Pump Dryer With Desiccant Enhanced Moisture Removal, Charles Cromer
Heat Pump Dryer With Desiccant Enhanced Moisture Removal, Charles Cromer
UCF Patents
A method and apparatus for enhancing the evaporation and moisture removal from moisture laden products in a dryer. The invention combines the inventor's prior U.S. Pat. No. 4,719,761, with a rotating drying drum having filters at the output area and a separate pump for allowing condensation from a chilled coil to drain off, while a desiccant formed from pads or a rotatable wheel is part of a continuous feedback loop for recycling moisture. A condenser is positioned between the desiccant and the drying drum and is used as a heat exchange for both the air inlet to the drum and …
Natural Language Method And System For Searching For And Ranking Relevant Documents From A Computer Database, James Driscoll
Natural Language Method And System For Searching For And Ranking Relevant Documents From A Computer Database, James Driscoll
UCF Patents
Natural Language search system and method for retrieving relevant documents from a text data base collection comprised of patents, medical and legal documents, journals, news stories and the like. Each small piece of text within the documents such as a sentence, phrase and semantic unit in the data base is treated as a document. Natural language queries are used to search for relevant documents from the data base. A first search query creates a selected group of documents. Each word in both the search query and in the documents are given weighted values. Combining the weighted values creates similarity values …
Coin Disks Replacement For Existing 3 1/2 Inch Floppy Discs, Issa Bataeseh, Zhihua Qu, Samuel Richie
Coin Disks Replacement For Existing 3 1/2 Inch Floppy Discs, Issa Bataeseh, Zhihua Qu, Samuel Richie
UCF Patents
A floppy disk cartridge adapter having a removable coin shaped memory disk. The 3 & 1/2 inch size cartridge adapter can fit into conventional personal computer disk drives. The small coin shaped magnetic disk has a diameter of approximately 1 inch, and can be easily snapped into and removed from the cartridge adapter. The coin disk fits on a spindle that is side by side to the floating drive plate used in regular 3 & 1/2 inch floppy diskettes. The spindle can be attached by various drive systems to rotate simultaneously with the rotating drive plate. One version is belt …
Optical Disk Readout Method Using Optical Coherence Tomography And Spectral Interferometry (Div.C), Peter Delfyett, Jannick Rolland
Optical Disk Readout Method Using Optical Coherence Tomography And Spectral Interferometry (Div.C), Peter Delfyett, Jannick Rolland
UCF Patents
An optical coherence tomography(OCT) and spectral interferometry imaging probe for the automatic screening and diagnosis of cervical and skin cancer in vivo. The probe eliminates the old techniques of having to perform Pap smears followed by a biopsy, known as colposcopy. The novel probe is cylindrical in shape and has a disposable outer plastic shield. Inside the probe is a motor driven rotatable casing having a planar optical fiber bundle array therein. The fiber bundle array has plastic light coupling lenslet arrays on both ends. The exposed end of the probe has one lenslet array disc that couples light between …

High Efficiency Ceiling Fan, Danny Parker, Bart Hibbs, Guan Su
UCF Patents
Ceiling fan blades for low speed fan operation. The blades have a positive twist at the root motor portion of the blade and a slightly twisted rounded tip. The chord of the blades taper down from the root to the rounded tip, and have a tapered airfoil from the aft forward aft edge to the trailing edge. The airfoil has a combination of a rounded leading edge with sharp trailing edge, and a square leading edge and rounded trailing edge. The blades can be twenty inches in length and twenty-six inches in length, and be used in ceiling fans having …
Polarization-Tunable Antenna-Coupled Infrared Detector, Glenn Boreman, Christos Christodoulou, Aristide Dogariu
Polarization-Tunable Antenna-Coupled Infrared Detector, Glenn Boreman, Christos Christodoulou, Aristide Dogariu
UCF Patents
An antenna-coupled infrared detector with polarization tuning over approximately 90 degrees by application of a bias voltage in the range of a few hundred millivolts. This mechanism of polarization tuning eliminates the need for bulk-optical polarization filters. When integrated into focal plane arrays, these detectors can be used in remote-sensing systems to facilitate enhanced image recognition, feature extraction and image-clutter removal. A preferred version of the antenna has longitudinal metal antenna arms extending outward from an infrared(IR) sensor in a spiral pattern, polarization tuning devices connected between the antenna arms, and a voltage for controlling the polarization tuning devices, wherein …
