Publication number: 20070212256Abstract: Provided herein are systems and methods associated therewith for killing molds and reducing other contaminating bioburden that may include bacteria and their spores, yeast, and viruses within various dwellings including homes, office buildings, institutions, and any other enclosed space in which humans reside, either temporarily or permanently. The technology of the present invention can be used to treat vehicles, airplanes, and ships. A process according to the invention includes the generation of a gaseous oxyhalogen species and distribution of the gaseous oxyhalogen species throughout a selected dwelling. It has been unexpectedly found that the concentration level of gaseous oxyhalogen species necessary to kill molds according to the inventive methods is far below that previously recognized in the art as being necessary for the killing of such molds. Thus, mold infestations may be killed in dwellings with minimal disruption to the usual business of the inhabitants.Type: ApplicationFiled: September 12, 2006Publication date: September 13, 2007Inventors: Danny Helton, David Hobson, Lawton Seal

Publication number: 20050150665Abstract: A fire extinguisher includes a tank and a gas generator breech connected to the tank. The gas generator breech is provided with a hermetically sealed gas generator cartridge. The hermetically sealed gas generator cartridge avoids the need to have a release poppet or burst shims on the gas generator breech. The enclosed space that contains combustion gas pressure is provided by the gas generator cartridge itself and not the gas generator breech. The gas generator cartridge is made from a container that can be the precursor to a beverage can used for carbonated beverages. The beverage can may come in a thickness and material of construction that makes it a suitable, cost-effective container for the gas generator cartridge. However, other containers besides precursors of beverage cans can be used.Type: ApplicationFiled: October 15, 2004Publication date: July 14, 2005Applicant: Aerojet-General CorporationInventors: Paul Wierenga, Cristy Kumasaka, David Hobson, Alexander Mathers

Patent number: 6025841Abstract: A method for managing simultaneous display of multiple windows in a graphical user interface (GUI). A computer system with a display and user interface input device displays a primary or container window on the display, comprising a predetermined region for displaying information and/or receiving user commands associated with a first computer process. The system displays a target window comprising a predetermined region for displaying information and/or receiving user commands associated with a different computer process. The target window is typically displayed in a higher z-order relative to the primary window to maintain it on top. In response to a predetermined triggering condition, the target window is manipulated by movement, temporary disappearance, and/or size reduction, while maintaining the relative z-order of the target window relative to the primary window and away from a predetermined avoidance region associated with the first computer process.Type: GrantFiled: July 15, 1997Date of Patent: February 15, 2000Assignee: Microsoft CorporationInventors: Erich Soren Finkelstein, Samuel David Hobson, Adrian Klein, Benjamin Waldman
