  • Publication number: 20140129198
    Abstract: Computer-implemented methods and non-transitory computer readable storage media facilitate calculating outflow of water from a selected catchment. A computer-implemented method calculates an outflow of water from a selected catchment is calculated. An identification of a selected catchment from a plurality of catchments within a geographical area is received from a user workstation. A database of multilayered data is accessed, where the data includes hydrological data, geophysical data, and meteorological data for each of the plurality of catchments within the geographical area. From the multilayered data, one or more additional catchments are automatically identified within the plurality of catchments, to identify a group of navigated catchments that drain into the selected catchment. For a given time period, a model is generated determining an outflow of water from the selected catchment and the group of navigated catchments.

  • Patent number: 8691171
    Abstract: A process for removing sulphur oxides from a fluid stream, such as flue gas, comprising: providing a non-aqueous absorption liquid containing at least one hydrophobic amine, the liquid being incompletely miscible with water; treating the fluid stream in an absorption zone with the non-aqueous absorption liquid to transfer at least part of the sulphur oxides into the non-aqueous absorption liquid and to form a sulphur oxide-hydrophobic amine-complex; causing the non-aqueous absorption liquid to be in liquid-liquid contact with an aqueous liquid whereby at least part of the sulphur oxide-hydrophobic amine-complex is hydrolyzed to release the hydrophobic amine and sulphurous hydrolysis products, and at least part of the sulphurous hydrolysis products is transferred into the aqueous liquid; separating the aqueous liquid from the non-aqueous absorption liquid.

  • Publication number: 20140080729
    Abstract: An optical sensing device and associated apparatus are configured for multiplexed detection of specific analytes in fluid samples. The device has a wavelength-tunable grating-coupler configuration in which a grating is disposed on a surface of a waveguide. Different regions of the grating may be functionalized with different receptors, and may form binding-specific sensors and reference sensors. The receptors are exposed to a fluid sample utilizing a fluidic structure mounted to the device. The device utilizes evanescent waves to sense analytes bound to the waveguide surface. The evanescent wave is sensitive to changes in refractive index at (or near) the waveguide surface. Changes in refractive index occur proportionally to the mass of the bound analyte. The apparatus utilizes a tunable light source to implement swept wavelength interrogation while the input beam is held at a fixed coupling angle relative to the waveguide and grating.

  • Patent number: 8671560
    Abstract: Low temperature bond balls connect two structures having disparate coefficients of linear thermal expansion. An integrated circuit is made to heat the device such that the low temperature bond balls melt. After melting, the bond balls solidify, and the device is operated with the bond balls solidified. In one example, one of the two structures is a semiconductor substrate, and the other structure is a printed circuit board. The integrated circuit is a die mounted to the semiconductor substrate. The bond balls include at least five percent indium, and the integrated circuit is an FPGA loaded with a bit stream. The bit stream configures the FPGA such that the FPGA has increased power dissipation, which melts the balls. After the melting, a second bit stream is loaded into the FPGA and the FPGA is operated in a normal user-mode using the second bit stream.

  • Publication number: 20140042753
    Abstract: An energy management system includes an energy storage reservoir and a fluid pump. The reservoir includes a fluid reservoir configured to contain varying quantities of a fluid and to isolate the fluid from the ambient. The fluid reservoir has a top surface, bottom surface, flexible member, and at least one opening for filling or emptying the reservoir. A pressing mass of solid material is positioned above the fluid reservoir with a weight sufficient to press the reservoir and empty the reservoir of fluid when the reservoir opening is open. The pressing mass is supported by the fluid reservoir when the reservoir contains fluid and is closed. The flexible member is disposed around the fluid reservoir to seal the fluid and to facilitate vertical motion of the pressing mass as the reservoir is filled and emptied. The pump supplies fluid to the fluid reservoir via the opening.

  • Patent number: 8541884
    Abstract: A TSV structure suitable for high speed signal transmission includes a metal strip portion that extends through a long and small diameter hole in a substrate. In one example, the metal strip portion is formed by laser ablating away portions of a metal sheath that lines a cylindrical sidewall of the hole, thereby leaving a longitudinal section of metal that is the metal strip portion. A second metal strip portion, that extends in a direction perpendicular to the hole axis, is contiguous with the metal strip portion that extends through the hole such that the two metal strip portions together form a single metal strip. Throughout its length, the single metal strip has a uniform width and thickness and therefore can have a controlled and uniform impedance. In some embodiments, multiple metal strips pass through the same TSV hole. In some embodiments, the structure is a coaxial TSV.
