Abstract: Embodiments of the present invention provide a Gaussian adaptive filter for ground clutter filtering and signal parameter estimation for weather radars in the time domain. In some embodiments, the filtering can be applied to dual polarization radar systems. In some embodiments, the clutter component of the signal can be transformed to noise. An interpolation procedure can then be used to recover the transformed part of the weather. A unique filter can be designed to use for both H and V channels for dual-polarization parameter estimation. In addition, the filter can be directly extended for staggered PRT 2/3 sampling scheme.

Abstract: Systems and methods for the prevention or dissolution of hydrates in an undersea well. One example system includes a submersible isolation bell for capturing effluent being exhausted from the well, and an umbilical. A power cable supplies electric power to the submersible isolation bell, for example for heating of the interior of the submersible isolation bell to prevent or discourage the formation of methane hydrates and the precipitation of other byproducts. Diluents may be supplied to the submersible isolation bell to further discourage the formation of hydrates and precipitation of other byproducts. The diluents may be heated locally at the submersible isolation bell, using electric power supplied by the power cable. A conformable seal may substantially seal the submersible isolation bell to a riser or other structure at the wellhead.

Abstract: The present invention provides microwave systems and methods for achieving better control of process and film properties by optimizing plasma containment shield shaping around an antenna. By using a containment shield, plasma generated by microwave may become more homogeneous, and the pressure inside a processing chamber may be reduced. By optimizing the shape of the containment shield, the lifetime of metastable radical species may be increased. One aspect of extending the lifetime of metastable radical species is to allow better control of chemical reaction and thus help achieve the desired film properties. For an array of antennas, the containment shield comprises a dielectric coated metal base with dividers between the antennas. The divider comprises a dielectric material or a mixture of a dielectric layer and a dielectric coated metal layer, and allows coupling among the antennas. Such a dielectric coated metal containment shield may be easier to be manufactured at lower cost than a containment shield comprising only dielectric material such as quartz.

Abstract: Method and systems for patterning a hardmask film using ultraviolet light is disclosed according to one embodiment of the invention. Embodiments of the present invention alleviate the processing problem of depositing and etching photoresist in order to produce a hardmask pattern. A hardmask layer, such as, silicon oxide, is first deposited on a substrate within a deposition chamber. In some cases, the hardmask layer is baked or annealed following deposition. After which, portions of the hardmask layer are exposed with ultraviolet light. The ultraviolet light produces a pattern of exposed and unexposed portions of hardmask material. Following the exposure, an etching process, such as a wet etch, may occur that removes the unexposed portions of the hardmask. Following the etch, the hardmask may be annealed, baked or subjected to a plasma treatment.
