20100012840 | METHOD AND SYSTEM FOR THERMAL IMAGING HAVING A SELECTIVE TEMPERATURE IMAGING MODE - The present invention is a method for operating a thermal imaging camera for selective temperature imaging, and a thermal imaging system having a selective temperature imaging mode. When first entering the selective temperature imaging mode of operation, the system and method automatically determine the hottest area in a scene and display it in a predetermined hue. The remainder of the scene is displayed in grayscale. The method and system allow further adjustment of the set point of the selective temperature imaging mode, and display portions of the scene as hot as or hotter than the set point value in gradient shades of the predetermined hue. | 01-21-2010 |
20090314295 | POWERED AIR PURIFYING RESPIRATOR - A powered air purifying respirator includes a housing defining an air inlet and an air outlet; a filter assembly operably connected to the housing for removing contaminants from air passing therethrough; an impeller/motor assembly contained within the housing for drawing air through the air inlet and through the filter; a flow sensor contained within the housing for measuring air flow from the air inlet to the air outlet; and a liner contained within the housing for locating and retaining the various internal components, while also aiding in attenuating a force of impact to the housing, the liner further defining an air pathway from the impeller/motor assembly through the flow sensor and to the air outlet. | 12-24-2009 |
