Patent number: 9260308Abstract: Process for producing nanomaterials such as graphenes, graphene composites, magnesium oxide, magnesium hydroxides and other nanomaterials by high heat vaporization and rapid cooling. In some of the preferred embodiments, the high heat is produced by an oxidation-reduction reaction of carbon dioxide and magnesium as the primary reactants, although additional materials such as reaction catalysts, control agents, or composite materials can be included in the reaction, if desired. The reaction also produces nanomaterials from a variety of other input materials, and by varying the process parameters, the type and morphology of the carbon nanoproducts and other nanoproducts can be controlled. The reaction products include novel nanocrystals of MgO (percilase) and MgAl2O4 (spinels) as well as composites of these nanocrystals with multiple layers of graphene deposited on or intercalated with them.Type: GrantFiled: April 16, 2013Date of Patent: February 16, 2016Assignee: Graphene Technologies, Inc.Inventors: Robert Wayne Dickinson, Oliver Douglas Ousterhout, Lawrence Joseph Musetti, Douglas Paul DuFaux

Publication number: 20150210558Abstract: Process for producing nanomaterials such as graphenes, graphene composites, magnesium oxide, magnesium hydroxides and other nanomaterials by high heat vaporization and rapid cooling. In some of the preferred embodiments, the high heat is produced by an oxidation-reduction reaction of carbon dioxide and magnesium as the primary reactants, although additional materials as reaction catalysts, control agents, or composite materials can be included in the reaction, if desired. The carbon dioxide and magnesium are combusted together in a reactor to produce nano-magnesium oxide, graphenes, graphene composites, and possibly other products which are then separated or excluded by suitable processes or reactions to provide the individual reaction products. The reaction is highly energetic, producing very high temperatures on the order of 5610° F. (3098° C.Type: ApplicationFiled: February 5, 2015Publication date: July 30, 2015Inventors: Robert Wayne Dickinson, Jon K.

Publication number: 20140014495Abstract: System and process in which graphene, which may be produced on a commercial scale, is highly purified, then functionalized in a vertical plasma reactor which can also deagglomerate and/or delaminate the graphene, as well as separating or classifying the functionalized graphene particles according to size. In one disclosed embodiment, the graphene is produced by combustion of magnesium (Mg) and carbon dioxide (CO2) in a highly exothermic reaction. The graphene is separated from the other reaction products and purified in a series of washing, heating, and drying steps, following which it is functionalized and otherwise processed in the plasma reactor.Type: ApplicationFiled: August 12, 2013Publication date: January 16, 2014Applicant: High Temperature Physics, LLCInventors: Robert Wayne Dickinson, Douglas Paul DuFaux, Maurice Yvon Belisle

Patent number: 8054187Abstract: A precipitation gauge for measuring liquid and frozen precipitation includes a support structure having at least one light sensor, or pair of electrodes, and at least one light source disposed thereon so that the light sensor may receive light that is emitted from the light source. The light sensor or light sensors and the light source or light sources generally extend a substantial height of the support structure. The light sensor or light sensors generate an output signal in response to the amount of light received from the light source. A microprocessor receives the output signal or output signals from the light sensor or light sensors and determines whether precipitation is present between the light sensor or light sensors and the light source or light sources. Based on the output signal or output signals, the microprocessor determines and displays the level of precipitation. The microprocessor may also determine the density of frozen precipitation.Type: GrantFiled: December 14, 2009Date of Patent: November 8, 2011Assignee: Noonan Technologies, LLCInventors: Douglas Paul Dufaux, John Paul Higgins

Patent number: 6798401Abstract: A virtual data input device to optically interface with an operator to detect the position of objects within an input zone, i.e., an area defined as a “virtual keyboard” in which the operator may interact to enter character or other data into computing equipment. The input device includes a source of optical sensor light illuminating the input zone that reflects off the objects in a direction generally toward the input device. The device also includes an optical detector arranged to receive reflected sensor light as a light pattern, representing the position of the objects within the input zone, and converts the reflected light pattern to an electrical signal. A microprocessor then receives the electrical signal and correlates the electrical signal to character or other data. An image generator may be used to project an optical image that represents, for example, an image of a keyboard.Type: GrantFiled: May 6, 2003Date of Patent: September 28, 2004Assignee: Tree Frog Technologies, LLCInventor: Douglas Paul DuFaux

Publication number: 20030193479Abstract: A virtual data input device to optically interface with an operator to detect the position of objects within a particular input zone, i.e., an area defined as a “virtual keyboard” in which the operator may interact to enter character or other data into associated computing equipment. Each character data corresponds to a unique arrangement and position of the objects within the input zone, e.g., operator's fingers on the virtual keyboard. The input device includes a source of optical sensor light illuminating the input zone with sensor light. The source of optical sensor light may be ambient light surrounding the operator or a light emitting device adapted to emit light in a direction toward the operator's fingers. The sensor light reflects off the objects in a direction generally toward the input device.Type: ApplicationFiled: May 6, 2003Publication date: October 16, 2003Inventor: Douglas Paul DuFaux
