Patent number: 8100836Abstract: The present invention generally relates to an apparatus and method analyzing the respiratory characteristics of a human respiratory system from impulse oscillometry data, through the use of a linear network of electrical components. The present invention offers an improved alternative to the RIC respiratory circuit model, with an addition of a peripheral resistance to account for the resistance presented by the respiratory system's small airways and of a capacitor to account for extrathoracic compliance. After air pressure and air flow measurements are obtained from the subject by performing Impulse Oscillometry System testing, a graphical representation of a mechanical impedance characteristic may be derived. This allows for the estimation and adjustment of parameter values of the linear network whose components correlate to the resistances, compliances and inertances inherent in the respiratory system.Type: GrantFiled: December 6, 2006Date of Patent: January 24, 2012Assignee: Texas Christian UniversityInventor: Billy Ming Diong

Patent number: 8100546Abstract: A sculpted decorative object, such as a Christmas tree, is shown which has a motor driven vertical drive shaft and three rotating sections. Rotation of the vertical drive shaft and an associated drive gear causes relative rotation of a driven gear and, in turn, a respective rotating section of the object about the axis of the drive shaft. A fiber optic bundle is mounted within each rotating section of the object. Each bundle contains several fiber optic strands which terminate at a LED light source at one end and at a light emitting element at an opposite end. Each LED light source is supplied from a common electrical source by means of a series of wiper contacts and rotatable contact rings carried by respective stationary and rotating portions of the sculpted object.Type: GrantFiled: March 1, 2010Date of Patent: January 24, 2012Inventors: Frank Lutz, Jon Turan

Patent number: 8033754Abstract: An installation technique is shown for use with a pre-insulated steam piping system having an inner steel carrier pipe surrounded by a layer of foam insulation and then by an outer protective jacket. An expansion loop is used to create an artificial low point in the overall pipeline which allows the pipeline to avoid a buried obstruction without the necessity of increasing the depth of the remaining portion of the pipeline on either side of the loop. The expansion loop has a pair of oppositely arranged side legs which are joined by a cross-leg portion of the loop, the cross-leg portion of the loop being angled downwardly at a predetermined angle, to thereby provide a change in elevation which avoids the buried obstruction in the pathway of the pipeline.Type: GrantFiled: August 19, 2009Date of Patent: October 11, 2011Assignee: Thermacor Process, L.P.Inventor: Thomas Joseph Keyes

Patent number: 8034147Abstract: A naturally occurring zeolite is coated with a special nanophase Fe oxide, thereby forming a nanophase Fe oxide coated zeolite. The composition thus formed can be used for a variety of horticultural and floricultural end applications. When the nanophase Fe oxide coated zeolite is dosed with plant nutrients and is then mixed with a suitable potting compound, the result is a Complete Plant Growth Medium (CPGM). Blending 5% to 25% CPGM by weight with sand, peat, compost, vegetable and flower beds, and native and manufactured soils, provides a number of beneficial properties. Also, CPGM alone can be used for growing indoor plants to avoid plant pests and compost odor.Type: GrantFiled: November 20, 2007Date of Patent: October 11, 2011Assignee: ChK Group, Inc.Inventors: Rajan K.

Patent number: 8028410Abstract: A regenerator core for use in a gas turbine regenerator has integral manifold openings formed in the tube plates used to make up the core and has special reinforcing elements which provide high pressure containment in critical portions of the plate-and-fin heat exchanger construction. The reinforcing elements include a series of hoops of U-shaped cross section which are used to bridge the juncture lines of the heat exchanger manifolds. An outer channel region of the hoops is provided with a reinforcing strip of gusset material. The hoops with their reinforcing strips provide structural reinforcement in the region between the manifolds and the conventional side bar reinforcing members in the central core section.Type: GrantFiled: April 23, 2009Date of Patent: October 4, 2011Inventor: Randy Thompson

Patent number: 8028872Abstract: A utility pocket is shown for use with a tool pouch or bag, or with such items as a brief case, soft sided cooler, or a backpack. The utility pocket has a clam shell shaped outer member which is biased toward an associated sidewall panel by means of elastic webbing. A pair of mating permanent magnets come into contact as the pocket moves from the open position to the closed position and help to bias the pocket to the closed position, as well as imparting a snap-closure action to the pocket. The material chosen for the pocket helps it to retain its clam shell shape without requiring internal reinforcing members, such as wire springs or other metal reinforcing elements.Type: GrantFiled: October 12, 2007Date of Patent: October 4, 2011Assignee: OmniQuest Ltd.Inventor: Brian Hamlin

Patent number: 8002002Abstract: A fluid filter draining device is shown for draining fluid from a fluid container, such as an oil filter, in a controlled manner. An engagement ring is frictionally engaged on the outer sidewalls of a fluid filter. The engagement ring carries a threaded screw with a sharpened tip and a channel communicating between an opening at a forward end of the screw and a rear region of the threaded screw. When the screw is turned it penetrates the sidewall of the fluid container and enters the fluid containing cavity of the filter. Fluid is drained through the channel in the drill tip and out through an associated swivel hose connection and swivel hose to a collection container.Type: GrantFiled: September 18, 2009Date of Patent: August 23, 2011Inventor: Bobby Knoll
