Publication number: 20130071297Abstract: A microplasma device includes a microcavity or microchannel defined at least partially within a thick metal oxide layer consisting essentially of defect free oxide. Electrodes are arranged with respect to the microcavity or microchannel to stimulate plasma generation in said microcavity or microchannel. At least one of the electrodes is encapsulated within the thick metal oxide layer. A method of fabricating a microcavity or microchannel plasma device includes anodizing a flat or gently curved or gently sloped metal substrate to form a thick layer of metal oxide consisting essentially of nanopores that are perpendicular to the surface of the metal substrate. Material removal is conducted to remove metal oxide material to form a microcavity or microchannel in the thick layer of metal oxide.Type: ApplicationFiled: June 20, 2012Publication date: March 21, 2013Applicant: The Board of Trustees of the University of IllinoisInventors: J.

Patent number: 8388900Abstract: An assembly and method for treating or otherwise improving an atmosphere contained within an enclosed space. The enclosed space can be a container such as a bag or other housing for equipment, food and/or suitable material. Ozone is generated within an atmosphere that is exposed to the material. The generated ozone is mixed with the atmosphere. At least a portion of the generated ozone is then removed from the mixed atmosphere. The assembly and method can be used to treat contaminated sports equipment and the like, as well as to treat food storage atmospheres, such as those exposed to fresh fruits and vegetables.Type: GrantFiled: October 14, 2009Date of Patent: March 5, 2013Assignee: Primaira, LLCInventors: Karen Benedek, Philip C. Carbone, Derek Affonce

Patent number: 8372345Abstract: An ozone generating apparatus includes a base container for holding water, and a head assembly connected to the upper edge of the base container, the head assembly containing a plurality of ozone generating cells each having a dielectric tube and an electrode assembly coaxially disposed within the associated dielectric tube. The dielectric tubes and electrode assemblies are disposed and connected such that the tube and/or electrode assembly of each ozone generating cell can be accessed independently of all other ozone generating cells, and such that the possibility of cascade failure of all remaining ozone generating cells upon failure of a single cell is substantially eliminated. The base container is provided with a process back flood prevention structure to protect the ozone generating cells.Type: GrantFiled: August 20, 2010Date of Patent: February 12, 2013Inventor: Wayne Wolf

Patent number: 8367007Abstract: A control circuit is connected to sense the impedance changes in a transformer driven ozone generating circuit cause by inadvertent immersion in water of the ozone generating field and to respond by reducing the strength of the ozone generating field as result thereof. To retain some ozone generating usefulness during the presence of mist or vapors in the ozone generating field the control circuit includes a series connected operational amplifier in the feedback loop that while operating in its linear range effects a proportional feedback response to reduce the ozone output. In this manner the usefulness of ozone generation is extended during highly active periods in a pool or spa.Type: GrantFiled: January 15, 2010Date of Patent: February 5, 2013Inventors: Edward R. Otero, Peter K. C. Yeh

Patent number: 8349253Abstract: A product package is provided for containing a product or object. The package contains a first agent that is energizably convertible by an energy source to a sanitizing agent including ozone in the package. The sanitizing agent including ozone in the package is transferred to the product or object while in the package. The first agent can include oxygen. The oxygen converts to ozone after being energized by ultraviolet radiation energy inside the package. The ultraviolet radiation energy can be radiated from outside the package, through the package, and into the package to energizably convert the oxygen to ozone in the package. The product or object in the package can be treated with the sanitizing agent including ozone in the package to provide a sanitizing, disinfecting, or sterilizing treatment, in the package.Type: GrantFiled: October 31, 2007Date of Patent: January 8, 2013Inventor: Jose Gutman
