Patent number: 8808733Abstract: Disclosed are methods and compositions for the controlled release of a drug or agent from a liposome using light or radiation. Also disclosed are compositions comprising liposomes having a lipid layer, wherein the liposomes contain an agent, an enzyme capable of releasing the agent from the liposome, and an enzyme activator sequestered by a molecular cage. In another aspect, methods of delivering an agent to a target in a subject are disclosed.Type: GrantFiled: March 31, 2010Date of Patent: August 19, 2014Assignee: The Board of Trustees of the University of ArkansasInventors: Daniel Fologea, Greg Salamo, Ralph Henry, Michael J.

Publication number: 20140147621Abstract: Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.Type: ApplicationFiled: November 29, 2012Publication date: May 29, 2014Inventors: Thomas Richard Chapman, Jacob George, Ralph Henry Hagg, Amit Halder, Huthavahana Kuchibhotla Sarma

Patent number: 8417959Abstract: The present disclosure relates to an apparatus and/or method of identifying a user comprising illuminating a user with electromagnetic energy to induce luminescence and producing an output data signal. A reference data signal corresponding to the luminescence of a selected user may be identified and compared to the output data signal. In such a manner, an identification may be made as to whether a selected user is present.Type: GrantFiled: December 18, 2006Date of Patent: April 9, 2013Assignee: Southwest Research InstituteInventor: Ralph Henry Hill, Jr.

Patent number: 8134127Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include a non-laser light source and thermal imaging camera that allow for detection of a target gas (or gasses) that absorbs at least some of the light source's wavelengths of operation. The light source can be implemented, for example, with an incoherent infrared (IR) light source, such as a resonance lamp configured with a gas cell containing a volume of a gas that, when excited by electric discharge, emits a wavelength that is absorbed by the target gas.Type: GrantFiled: July 29, 2011Date of Patent: March 13, 2012Assignee: Southwest Research InstituteInventor: Ralph Henry Hill, Jr.

Patent number: 8085301Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.Type: GrantFiled: March 16, 2009Date of Patent: December 27, 2011Assignee: Southwest Research InstituteInventors: Ralph Henry Hill, Jr., Joseph Nathan Mitchell

Patent number: 8011188Abstract: A gas turbine engine augmentor includes an annular trapped vortex cavity pilot having a cavity forward wall, a cavity radially outer wall, and a cavity aft wall, an annular cavity therebetween, and cavity fuel injector tubes operably disposed through the outer wall into the cavity. Circumferentially spaced apart radial flameholders with integral spraybars and/or radial spraybars interdigitated with the radial flameholders radially inwardly into an exhaust flowpath of the augmentor just forward and upstream of the trapped vortex cavity pilot at a radially outer portion of a combustion zone of the exhaust flowpath. An annular trapped dual vortex cavity pilot version is operable for producing trapped dual counter-rotating inner and outer vortices of fuel and air mixtures.Type: GrantFiled: August 31, 2007Date of Patent: September 6, 2011Assignee: General Electric CompanyInventors: Ivan Elmer Woltmann, Sean Stacey Archer, Frank Gerald Bachman, Ralph Henry Winslow

Patent number: 7858756Abstract: The invention generally relates to monoclonal antibodies that recognize at least one compound from the group consisting of (+) methamphetamine, (+) amphetamine, and (+) 3,4-methylenedioxymethamphetamine ((+) MDMA). Generally speaking, the monoclonal antibodies do not recognize (?) methamphetamine, (?) amphetamine, or (?) MDMA.Type: GrantFiled: June 15, 2007Date of Patent: December 28, 2010Assignee: The Board of Trustees of the University of ArkansasInventors: S. Michael Owens, Melinda Gunnell, Yingni Chi, F.

Patent number: 7803303Abstract: A plugging apparatus for plugging channels in a honeycomb structure used to form a particulate filter. The apparatus includes an extrusion apparatus that holds plugging material and that has an opening through which the plugging material is extruded. An extrusion plate having first through holes that correspond in location to a subset of honeycomb channels is arranged adjacent the opening. An annular flow plate is operatively arranged face-to-face with the extrusion plate. The annular flow plate has second through holes corresponding in location to the first through holes but that are smaller to compensate for a radial variation in the extrusion rate when plugging the channels in the honeycomb structure. The plugging apparatus is thus able to fill select channel ends with same-size plugs, which leads to a better-performing filter.Type: GrantFiled: November 29, 2007Date of Patent: September 28, 2010Assignee: Corning IncorporatedInventor: Ralph Henry Hagg

The segment may include a forward subcomponent including the cavity forward wall attached to an aft subcomponent including the cavity aft wall. The forward and aft subcomponents include forward and aft portions of the cavity radially outer wall respectively. A ring of the segments may be circumferentially disposed about an axis to form an annular segmented vortex cavity assembly.Type: GrantFiled: July 21, 2006Date of Patent: August 24, 2010Assignee: General Electric CompanyInventors: Leonard Paul Grammel, Jr., David Lance Pennekamp, Ralph Henry Winslow, Jr.
