摘要： An apparatus for dissociating gases includes a plasma chamber that may be formed from a metallic material and a transformer having a magnetic core surrounding a portion of the plasma chamber and having a primary winding. The apparatus also includes one or more switching semiconductor devices that are directly coupled to a voltage supply and that have an output coupled to the primary winding of the transformer. The one or more switching semiconductor devices drive current in the primary winding that induces a potential inside the chamber that forms a plasma which completes a secondary circuit of the transformer.

摘要： An improved toroidal low-field plasma source allows plasma ignition within a wider range of gas conditions than permitted by prior art plasma sources. Power efficiency of the plasma source is improved by automatically adjusting the power delivered to the plasma based on the load to the power supply. The plasma source can be operated over a wider pressure range than allowed by prior art plasma sources. The plasma source can be operated so as to increase the output of atomic species from the source. The plasma source can be operated to increase the etch rate of organic materials. The plasma source can efficiently remove hazardous gas compounds from effluent gas streams by converting them into scrubbable products.

摘要： A system for defining structures within an image is described. The system includes reading of an input file, preprocessing the input file while preserving metadata such as scale information and then detecting features of the input file. In one version the detection first uses an edge detector followed by identification of features using a Hough transform. The output of the process is identified elements within the image.

摘要： A power system for a dielectric barrier discharge system, such as used for generating ozone, can include a full bridge inverter stage and parallel resonant tank outputting a signal for powering a dielectric barrier discharge cell stack. The inverter stage is controlled using a combination of pulse width modulation (PWM) and frequency modulation (FM) to enable soft switching through all load conditions—from full load to light load. A current control loop error amplifier compensator can provide a duty cycle adjustment signal to a phase shift PWM controller chip that generates the switching signals for the inverter stage. A feedback signal is also used to adjust a clock frequency time constant of the PWM controller chip to provide the FM. In one embodiment, the feedback signal is an output of an inverting amplifier connected at an output of the current control loop error amplifier compensator.

摘要： A system and methods are described for generating reagent ions and product ions for use in a mass spectrometry system. Applications for the system and method are also disclosed for detecting volatile organic compounds in trace concentrations. A microwave or high-frequency RF energy source ionizes particles of a reagent vapor to form reagent ions. The reagent ions enter a chamber, such as a drift chamber, to interact with a fluid sample. An electric field directs the reagent ions and facilitates an interaction with the fluid sample to form product ions. The reagent ions and product ions then exit the chamber under the influence of an electric field for detection by a mass spectrometer module. The system includes various control modules for setting values of system parameters and analysis modules for detection of mass and peak intensity values for ion species during spectrometry and faults within the system.

摘要： An improved plasma vessel (i.e., plasma applicator) that provides effective cooling includes a plurality of generally linear tubes having a dielectric interior fluidly connected together by dielectric connectors. The tubes and connectors are joined together to form a leak-tight plasma vessel. A cooling system surrounding the improved plasma vessel includes a rigid cooling plate and a deformable thermal transfer material disposed between the plasma vessel and the cooling plate. After use or at an operator's discretion, the plasma vessel can be removed from the cooling system and a new vessel may be inserted in its place. Alternatively, the used vessel may be refurbished and re-inserted into the cooling system. The new or refurbished vessel may or may not be of the same size or configuration as the used vessel. Thermal contact between the cooling system and the new or refurbished vessel, however is maintained through the deformable thermal transfer material.
