| 20080264140 | VAPORIZED HYDROGEN PEROXIDE PROBE CALIBRATION RIG - A method and apparatus for calibrating a sensor used to sense the concentration of vaporized hydrogen peroxide (VHP). A concentration of liquid hydrogen peroxide in an aqueous solution is determined and correlated with a corresponding concentration of vaporized hydrogen peroxide indicative of an “actual” vaporized hydrogen peroxide concentration. An error value is determined by comparing the “actual” vaporized hydrogen peroxide concentration to a “measured” vaporized hydrogen peroxide concentration, indicated by the sensor being calibrated. The error value is used to properly calibrate the sensor. | 10-30-2008 |
| 20080267818 | VAPORIZED HYDROGEN PEROXIDE DECONTAMINATION SYSTEM WITH CONCENTRATION ADJUSTMENT MODE - A decontamination system for decontaminating a region with a vaporized decontaminant, such as vaporized hydrogen peroxide. The concentration of the vaporized decontaminant within the region is modified in response to operating conditions. The decontamination system adjusts the concentration of the vaporized decontaminant in response to the monitored saturation concentration of the decontaminant, thereby preventing condensation of the vaporized decontaminant during a decontamination cycle. The decontamination system also adjusts the concentration of the vaporized decontaminant in order to minimize the time required to complete a successful decontamination operation. | 10-30-2008 |
| 20080279722 | TRANSPORTABLE DECONTAMINATION UNIT AND DECONTAMINATION PROCESS - The disclosed invention relates to a portable decontamination unit. The invention also relates to a decontamination process. The decontamination unit may be ruggedized for use in hostile environments such as those that may be anticipated for military applications. | 11-13-2008 |
| 20090047174 | METHOD AND APPARATUS FOR DECONTAMINATING A REGION WITHOUT DEHUMIDIFICATION - A method and apparatus for decontaminating a region with a gaseous or vaporous decontaminant (e.g., vaporized hydrogen peroxide) without dehumidification (e.g., without the use of a dryer). The saturation concentration of the decontaminant inside the region is monitored, and the concentration of the decontaminant inside the region is regulated to prevent condensation of the decontaminant. The bioburden reduction is continuously monitored during a decontamination phase to ascertain successful completion of a decontamination process in accordance with a target bioburden reduction. | 02-19-2009 |
| 20090087921 | VAPORIZED HYDROGEN PEROXIDE CONCENTRATION DETECTOR - A method of determining the presence of vaporized hydrogen peroxide (VHP) in a region, comprising the steps of providing a sealable region having an inlet port and an outlet port, creating a flow of a carrier gas into, through and out of the region, delivering vaporized hydrogen peroxide into the carrier gas flow upstream of the region inlet port, destroying the vaporized hydrogen peroxide at a first location downstream from the region outlet port, monitoring the temperature of the carrier gas before and after the first location, and determining a presence of vaporized hydrogen peroxide in the region based upon the temperature readings before and after the first location. | 04-02-2009 |
| 20110072759 | BOTTLE DECONTAMINATION SYSTEM - A system for sterilizing bottles with a gaseous sterilant. The system includes moving means for continuously moving bottles one after another along a path. An assembly is provided for distributing a predetermined amount of the gaseous sterilant from a source of gaseous sterilant to each of the bottles. The assembly includes a plurality of injectors that are movable with the bottles. One of the plurality of injectors is associated with each of the bottles. The injector is fluidly connected to the source of gaseous sterilant when the bottle associated with the injector is disposed along a first portion of the path. The injector is disposed above the bottle when the injector is in a first position. The injector is disposed within an interior of the bottle when the injector is in a second position such that the predetermined amount of the gaseous sterilant is conveyed into the interior of the bottle. | 03-31-2011 |
| 20110076189 | FEED BACK AND DOSE CONTROL OF DISTRIBUTED DECONTAMINATION SYSTEMS - A sterilization system includes a plurality of vaporizers that are controlled by a network of interconnected controllers. The network includes a plurality of control units with each control unit controlling an associated vaporizer to adjust independently the rate at which the associated vaporizer injects vaporized sterilant into the different regions of an enclosure. The network also includes a master control unit configured to control each control unit over the network to coordinate the aggregate injection of sterilant vapor. | 03-31-2011 |
