  • Patent number: 10238761
    Abstract: The present invention is an improved method for decontamination of a space and an integrated device that completes the decontamination cycle extremely fast while still being compact, lightweight, simple to operate and easy to move as a single unit. The method of the present invention delivers less biocide than is used in prior art methods at a very high rate of flux, allows the biocide to reside in the space being decontaminated to achieve a predetermined kill level, and then aerates the space. Because a nominal amount of biocide is used, there is less biocide to remove from the space than in prior art methods thereby reducing the time required for aeration and shortening the downtime for safe entry of the facility.

    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).

  • Publication number: 20140271347
    Abstract: Provided are methods for decontamination of compartments, such as aircraft compartments and other types of compartments, and systems for implementing these methods. In some embodiments, a method involves detecting presence of one or more contaminants in a compartment. This information is used to select various decontamination conditions. In some embodiments, additional information, such as the type of the compartment (e.g., an aircraft compartment), temperature, and humidity, may be also considered while selecting the decontamination conditions. The decontamination conditions include identification of one or more decontaminating agents to be dispensed in the compartment, temperature profile of the air to be flown into the compartment, and timing of the decontaminant dispensing and air flowing operations. These conditions are selected to increase efficacy of the selected decontaminating agents with respect to the one or more detected contaminants and reduce impact on the aircraft compartment.

  • Patent number: 8771593
    Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.
