    Abstract: Methods and systems (10) for plasma-assisted nitrogen surface-treatments are provided. The method can include subjecting a gas (24) to electromagnetic radiation (26) in the presence of a plasma catalyst (100, 120, 140) to initiate a plasma containing nitrogen. The surface region of an object can be exposed to the plasma for a period of time sufficient to transfer at least some of the nitrogen from the plasma to the object through the surface region.

In one embodiment, an engine exhaust treatment system includes at least one conduit with an inlet portion (215), an outlet portion (216), an intermediate portion (205), and at least one plasma cavity (210). The inlet portion is configured to connect to an engine block (510) and receive an exhaust gas. The outlet portion emits the exhaust gas after plasma treatment. The intermediate portion conveys the exhaust gas from the inlet portion to the outlet portion. In one embodiment, one or more plasma cavities (342, 344, 346) are located proximate to the inlet portion for treating the exhaust gas. The system also includes an electromagnetic radiation source (340) connected to the cavities for supplying radiation to the cavities, wherein the radiation has a frequency less than about 333 GHz.

    Abstract: Methods and apparatus are provided for plasma-assisted gas production. In one embodiment, a gas, which includes at least one atomic or molecular species, can flow into a cavity (305). The gas can be subjected to electromagnetic radiation having a frequency less than about 333 GHz (optionally in the presence of a plasma catalyst) such that a plasma (310) forms in the cavity (305). A filter (315) capable of passing the atomic or molecular species, but preventing others from passing, can be in fluid communication with the cavity (305). In this way, the selected species can be extracted and collected, for storage or immediate use.

    Abstract: Apparatus for suppressing fluid-borne noise in a fluid conduit (12 or 12a) that includes a vibration sensor (36, 36a or 36b) for operative coupling to the conduit for providing an electrical sensor signal as a function of fluid pressure fluctuations in the conduit. A piezoelectric actuator (40, 40a or 40b) is adapted to be mounted on the conduit for imparting pressure fluctuations to fluid in the conduit. An electronic controller (38, 38a or 38b) is responsive to the sensor signal for energizing the actuator 180° out of phase with fluid pressure fluctuations sensed by the sensor. The sensor may be either closely coupled to the actuator, or separate from the actuator and disposed upstream of the actuator with respect to the direction of fluid flow through the conduit. The sensor in the preferred embodiments of the invention comprises a piezoelectric sensor, and the actuator comprises a stack of piezoelectric elements.
