Abstract: A subgrade with local deep excavation and backfilling structure and a rapid construction method thereof are provided. Supporting cast-in-place piles are laid at positions where an underground pipe gallery is located in a subgrade structure, and soil there between are longitudinally excavated to form a line-shaped foundation pit. A bottom of the line-shaped deep foundation pit is reinforced to support the underground pipe gallery, and lateral peripheral regions and top peripheral regions of the underground pipe gallery are backfilled with block geobag reinforced fillers. Geogrids are placed on the top of the underground pipe gallery, then backfilling compaction and reinforcing are performed, and the geogrids are fixedly assembled with anchor bolts. The construction method is simple and easy. By using compacted block geobag reinforced fillers and cement solidified slurry, an overall quality of the subgrade structure after backfilling can be ensured, and construction period and cost can be greatly reduced.

Abstract: The present invention relates to the technical field of filtering materials and provides a reverse osmosis membrane support material. The support material is obtained by hot pressing treatment of a surface layer, a middle layer and a bottom layer which are sequentially disposed from top to bottom. The surface layer and the bottom layer are each a spunbond non-woven fabric layer made of thermoplastic polymer spunbonded fibers, and the middle layer is a polymer nanofiber membrane. In accordance with the invention, the comprehensive mechanical strength of the reverse osmosis membrane support material is improved, and the overall anti-leakage performance is enhanced. A spunbond technology and a nanofiber preparation technology are combined organically, and the method is simple and controllable. The support material can be produced in batches.

Abstract: A system is configured to determine a color distribution of an object moving along a flow direction relative to a spatial filter. The light emanating from the object is time modulated according to the mask features of the spatial filter. First and second detectors are arranged to sense the modulated light. The first detector senses light having a first wavelength spectrum and generates a first electrical output signal in response to the sensed light. The second detector light senses light having a second wavelength spectrum and generates a second electrical output signal in response to the sensed light. Signals from the first and second detectors include information about color distribution of the object.

Abstract: Spatially modulated light emanating from an object moving along a flow path is used to determine various object characteristics including object length along the flow direction. Light emanating from at least one object moving along in a flow path along a flow direction of a spatial filter is sensed. The intensity of the sensed light is time modulated according to features of the spatial filter. A time varying electrical signal is generated which includes a plurality of pulses in response to the sensed light. Pulse widths of at least some of the pulses are measured at a fraction of a local extremum of the pulses. The length of the object along the flow direction is determined based on the measured pulse widths.

The detected light has a component along a detection axis that makes a non-zero angle with respect to the longitudinal and lateral axes. An electrical output signal that includes information about the trajectory depth of the object is generated in response to the detected light.

Abstract: A light emitting device includes a p-side heterostructure, an n-side heterostructure, an active region disposed between the p-side heterostructure and the n-side heterostructure. An electron blocking layer (EBL) disposed between the p-side heterostructure and the active region comprises an aluminum containing group-III-nitride alloy. An aluminum composition of the EBL decreases as a function of distance along a [0001] direction from the active region towards the p-side heterostructure over a majority of the thickness of the EBL.

Abstract: A device includes a spatial filter arranged in a Cartesian coordinate system having orthogonal x, y, and z axes. The spatial filter has mask features that are more light transmissive and mask features that are less light transmissive. The mask features are arranged along the x-axis in the flow direction of a flow path. A detector is positioned to detect light emanating from at least one object in the flow path, the object having a width along the y-axis, a thickness along the z-axis, and a length along the x-axis. Light emanating from the object is time modulated according to the mask features as the object moves along the flow path. The detector is configured to generate a time-varying electrical signal in response to the detected light that includes information about the width or thickness of the object.

Abstract: An ionic wind engine unit for cooling semiconductor circuit assemblies includes a curved micro-spring and an associated electrode that are maintained apart at an appropriate gap distance such that, when subjected to a sufficiently high voltage potential (i.e., as determined by Peek's Law), current crowding at the spring's tip portion creates an electrical field that sufficiently ionizes neutral molecules in a portion of the air-filled region surrounding the tip portion to generate a micro-plasma event. In one engine type the electrode is a metal pad, and in a second engine type the electrode is a second micro-spring. Ionic wind cooling is generated, for example, between an IC die and a base substrate in a flip-chip arrangement, by controlling multiple engines disposed on the facing surfaces to produce an air current in the air gap region separating the IC device and base substrate.
