Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.Type: GrantFiled: August 2, 2007Date of Patent: September 6, 2011Assignee: Vollara, LLCInventors: James Normark, Neal Morris, Allen Johnston

Patent number: 8008640Abstract: The present invention includes a system, methods and apparatus for sterilization of an object (e.g., food products). The present invention takes advantage of the electron scatter that occurs when electron beam is applied onto a surface. The present invention is capable of treating irregular surfaces (e.g., carcasses, spherical/round surfaces) or any type of surface where complete penetration is not needed or desired.Type: GrantFiled: July 1, 2009Date of Patent: August 30, 2011Assignee: The Texas A&M University SystemInventors: Joseph E. Maxim, Jack A. Neal, Alejandro Castillo

Patent number: 7989779Abstract: A universal ultraviolet light sanitation device that can be mounted to existing doors and the like wherein the UV light sources are positioned for treatment of a door knob or handle. The device provides for opposing UV lights in a light emitting housing around the doorknob. Sensor means within the assembly determines the non-presence of the user's hand and activates the UV lights before and after handle contact assuring sanitation of the light exposed non-porous surfaces.Type: GrantFiled: January 27, 2009Date of Patent: August 2, 2011Inventors: David A. Ray, Martin M. Abitzsch

Patent number: 7985956Abstract: There is described a fluid treatment system which may which may be used with radiation sources that do not require a protective sleeveāe.g., excimer radiation sources. An advantage of the present fluid system treatment is that the radiation sources may be removed from the fluid treatment zone without necessarily having to shut down the fluid treatment system, remove the fluid, break the seals which retain fluid tightness, replace/service radiation source and than reverse the steps. Instead, the present fluid treatment system allows for service/replacement of the radiation sources in the fluid treatment zone during operation of the fluid treatment system.Type: GrantFiled: December 21, 2006Date of Patent: July 26, 2011Assignee: Trojan Technologies Inc.Inventors: Jim Fraser, Michael Sasges

Publication number: 20110172810Abstract: Systems and methods to reduce bioburden on at least a portion of a fluid transfer port include supplying a dose of radiation to the portion in optical communication with at least one source of radiation. In an illustrative example, a medical container, such as a vial or IV bag, receives a dose of ultraviolet (UV) energy substantially at a predetermined region of a fluid transfer site. In some examples, such a sanitization process may precede a fluid transfer operation in which a fluid is transferred into or out of the medical container by passing through the sanitized region. Such fluid transfers may be used in automated or semi-automated pharmaceutical processes, such as drug reconstitution. Various embodiments may further include one or more seal assemblies, each seal assembly having an aperture through which the radiation dose is supplied from the source to a controlled region on the fluid transfer port.Type: ApplicationFiled: March 28, 2011Publication date: July 14, 2011Applicant: INTELLIGENT HOSPITAL SYSTEMS LTD.Inventors: Lance R.

Patent number: 7976777Abstract: A method, a sensor device (204), and a package storage system (200), are used to monitor the inside of a storage volume in a package container (202) containing at least one product and/or object (201). The sensor device is inside of the storage volume in the package container (202) and senses the presence of at least one of a sanitizing agent comprising ozone (316) and ultraviolet radiation energy inside of the storage volume. The sensor device (204) wirelessly transmits the sensed information from inside the at least one storage volume to a wireless receiver (222) outside of the storage volume to provide the sensed information to a processor (220) that monitors the presence of the at least one of the sanitizing agent comprising ozone (316) and ultraviolet radiation energy inside of the storage volume in the package container (202). The sensor device (204) can communicate using an RF ID device communication protocol.Type: GrantFiled: September 13, 2005Date of Patent: July 12, 2011Inventor: Jose Gutman

Patent number: 7972558Abstract: A method and an apparatus for sterilizing packaging material for use in packaging for protein containing products, such as food products or medical drugs. The packaging material is sterilized by irradiating it using a beam of ionizing radiation, such as an electron beam or a beam of gamma rays. Afterwards, the packaging material is processed in such a manner that protein reactive substances or compounds formed in the packaging material during the irradiation step are at least partly removed or rendered inreactive with respect to proteins. The processing step may advantageously be performed by heating the packaging material. Preferably, the processing step involves accelerating diffusion from the packaging material of protein reactive substances or compounds. Since the protein reactive substances or compounds are removed or rendered inreactive with respect to proteins, degradation of the product which is later stored in the packaging material is considerably reduced.Type: GrantFiled: February 28, 2007Date of Patent: July 5, 2011Assignee: Novo Nordisk A/SInventors: Lasse Hansen, Anders Dossing Norskov, Per Jeppensen, Signe Agnete Christensen

Publication number: 20110155924Abstract: A sterilizing apparatus is adapted for sterilizing kitchen utensils, and includes a hollow housing cooperating with a bottom seat and a top cover to define an accommodating space for receiving the kitchen utensils, and a transparent plate impermeable to ultraviolet light and disposed in front of and covering openably the accommodating space. Two sterilizing lamp mechanisms are disposed in the accommodating space, and are spaced apart from each other in a left-to-right direction, such that the kitchen utensils are disposed between the sterilizing lamp mechanisms. The sterilizing lamp mechanisms emit ultraviolet rays onto the kitchen utensils.Type: ApplicationFiled: March 30, 2010Publication date: June 30, 2011Inventor: Tien-Jen Lo
