Abstract: A method can be used for fabricating first and second semiconductor regions separated by isolating trenches. A semiconductor substrate is covered with silicon nitride. The silicon nitride situated above the first region is doped by ion implantation. Trenches are etched through the silicon nitride and the doped silicon nitride is partially etching in an isotropic manner. The trenches are filled with an insulator to a level situated above that of the first region. The silicon nitride is removed resulting in the edges of the first region only being covered with an insulator annulus.

Abstract: This invention discloses an airlift pumping mechanism for a fluid container, which is intended to address the problem of decreasing efficiency of the pumping mechanism when the liquid level in the container is low in the prior art. For this purpose, the airlift pumping mechanism comprises an air compressor and a riser tube assembly, wherein the riser tube assembly is located in a fluid container, and the air compressor is in communication with the riser tube assembly for feeding the compressed air to the riser tube assembly so that the same flows upward through the riser tube assembly together with the fluid in the fluid container. The pumping mechanism is characterized by further comprising a sunken cavity downwardly extending from the inner bottom surface of the fluid container, wherein the sunken cavity is located between the air compressor and the riser tube assembly and is in communication with the air compressor and the riser tube assembly.

Abstract: An embodiment of a method includes receiving seismic data from an array of seismic receivers, selecting a time window, and dividing the time window into a plurality of consecutive time segments, each corresponding to a subset of the seismic data. The method also includes performing a transformation of each subset into a frequency domain subset having a total frequency band, and selecting a narrow frequency band bounded by the lowest frequency of the total band and a threshold frequency. The method further includes, for each of the plurality of frequencies in the narrow frequency band, determining a cross-spectral density matrix (CSDM) of data values in each frequency domain subset, decomposing the CSDM to generate a plurality of eigenvalues, and removing at least the most significant eigenvalue from each frequency domain subset. The method still further includes transforming each frequency domain subset into a time domain to generate de-noised seismic data.

Abstract: A spherical wheel to move a vehicle comprises two caps, the surface of which follows the spherical surface of the wheel, the caps being articulated by means of a pivot link relative to a shaft. The wheel further comprises two casters each arranged in an opening of each of the caps, the opening centered about the axis of the corresponding pivot link, each caster arranged in the extension of the pivot link of the cap concerned. Each caster ensures a rolling at the level of the spherical surface. Radii S of the opening of each cap and r of the corresponding caster are defined to substantially balance forces needed to drive a cap and the corresponding caster when the wheel goes from bearing on the ground on a cap at the edge of the opening to bearing on the ground on the corresponding caster.

Abstract: A system and method are provided for filtering scatterer noise energy from land seismic waves using three dimensional (3D) iterative filtering in a cross-spread source-receiver pattern. The system and method isolate scatterer noise energy associated with a scatterer based on a filtering process performed using a scatterer referential time delay. Then, the isolated scatterer noise energy can be subtracted from the surface wave data. This process can be repeated for each scatterer in the covered area to remove each of their contributions, and can be performed, for example, after a preliminary filtering of the surface wave data using 3D fk filtering or the like.
