Abstract: Pest control in an enclosed area, such as a room of a building, by positioning an ozone producing device in an area to be treated. Ozone generating ultraviolet lamps emit ozone around the entire perimeter of the device, generating ozone from the atmosphere within the enclosed area. A concentration of ozone in the area is measured by a sensor. Production of ozone by the ozone generating ultraviolet lamps is terminated upon the ozone concentration reaching a predetermined concentration of ozone or by time of exposure. Pests that are subject to treatment include invertebrates, such as insects and arachnids, or small mammals, such as mice and rats.

Abstract: Devices and methods for defining a data set, referred to herein as a signature, for a particular device having interior channels. A baseline signature is established for the particular device while the particular device is known to be in a decontaminated condition. After use of the device and subsequent decontamination of the device, a signature for the particular device is determined and compared with the baseline signature to verify that the latter signature is within an acceptable range.

Abstract: A disinfector disinfects an object having channels therein, such as an endoscope, by one or more light emitting diodes that emit UV-C radiation. The object, including interior channels of the object, is exposed to emissions of UV-C radiation. One or more light emitting diodes provide UV-C radiation to the interior channels of the object. Operation of the device through the channels is responsive to cumulative levels of radiation received by the sensor(s) associated with the light emitting diode(s).

Abstract: An ultraviolet area sterilizer (UVAS) is mobile or stationary. The UVAS is positioned in a room, such an operating room or intensive care unit. Motion detectors sense movement, to assure that personnel have evacuated the space to be sterilized. Subsequently, UV-C generators, such as a bank of mercury bulbs, generate intense levels of UV-C. An array of multiple UV-C sensors scan the room, and determine the darkest area, or the area reflecting the lowest level of UV-C back to the sensors. A BASIC Stamp contained in the device calculates the time required to obtain a bactericidal dose of UV-C reflected back from darkest area. Once a bactericidal dose has been reflected to all the sensors, the unit notifies the operator and shuts down. By relying on reflected doses rather than direct exposure, the UVAS is able to sterilize or sanitize all surfaces within the room that are within view of an exposed wall or ceiling.
