A floating wind turbine platform includes a floatation frame (105) that includes three columns (102, 103) that are coupled to each other with horizontal main beams (115). A wind turbine tower (111) is mounted above a tower support column (102) to simplify the system construction and improve the structural strength. The turbine blades (101) are coupled to a nacelle (125) that rotates on top of the tower (111). The turbine's gearbox generator and other electrical gear can be mounted either traditionally in the nacelle, or lower in the tower (111) or in the top of the tower-supporting column (102). The floatation frame (105) includes a water ballasting system that pumps water between the columns (102, 103) to keep the tower (111) in a 10 vertical alignment regardless of the wind speed. Water-entrapment plates (107) are mounted to the bottoms of the columns (102, 103) to minimize the rotational movement of the floatation frame (105) due to waves.

An improved multi-layered diagnostic sanitary test strip for receiving a heterogenous fluid, such as whole blood, to test for presence and/or amount of a suspected analyte in the fluid by facilitating a color change in the strip corresponding to the amount of the analyte in the fluid, wherein the test strip includes fluid volume control dams to prevent spillage of the fluid from the strip and a chemical reagent solution that facilitates end-point testing. The improved test strip comprises no more than two operative layers and: (a) a reaction membrane containing a reagent capable of reacting with the analyte of interest to produce a measurable change in said membrane; (b) an upper support layer defining a sample receiving port for receiving the fluid sample thereat; (c) one or more structures for directing the sample containing the analyte of interest through at least a portion of said reaction membrane; and (d) a lower support layer having a reaction viewing port in vertical alignment with said membrane for displaying said measurable change, said lower support being associated with said upper support to secure said reaction membrane in said test strip.

The present invention provides a vertical alignment film having a polymerizable liquid crystal compound having negative dielectric constant anisotropy, where the polymerizable liquid crystal compound is vertically aligned against the surface of the substrate, and then the polymerizable liquid crystal compound is fixed to form the vertical alignment film.

A vertical alignment liquid crystal layer is sealed between a first substrate having a first electrode and a second substrate having a second electrode, each pixel region has a reflective region and a transmissive region, and a gap adjusting section is provided on one of sides of the first substrate and the second substrate which sets a thickness (gap) d of the liquid crystal layer which controls a phase difference of incident light to the liquid crystal layer so that a gap dr in the reflective region is smaller than a gap dt in the transmissive region. An alignment controller which divides alignment of the liquid crystal within a pixel region is provided in the pixel region on at least one of the sides of the first substrate and the second substrate. It is also possible to optimize by changing the gap in red, green, and blue.

The present invention provides a liquid crystal display device having a high display quality. The liquid crystal display device displays an image by applying a voltage by a first electrode and a second electrode across a liquid crystal layer which takes a vertical alignment in the absence of an applied voltage. The first electrode includes a lower conductive layer, a dielectric layer covering at least a portion of the lower conductive layer, and an upper conductive layer provided on one side of the dielectric layer which is closer to the liquid crystal layer. The upper conductive layer includes a first opening, and the lower conductive layer is provided so as to oppose at least a portion of the first opening via the dielectric layer.

A vertical alignment liquid crystal display device capable of a complete contrast compensation, particularly by performing an optical compensation using an optically uniaxial anisotropic sheet and an optically biaxial anisotropic sheet. A retardation of the optically uniaxial anisotropic sheet should have an opposite sign to the retardation of a liquid crystal layer, and absolute value of the retardation of the optically uniaxial anisotropic sheet should be within the range of 75 to 100% of the retardation of the liquid crystal layer. The optically uniaxial anisotropic sheet may be united with a polarizing plate. The optically biaxial anisotropic sheet should have a retardation axis which is parallel to a transmitting axis of any one of the polarizing plates. The optically biaxial anisotropic sheet should exhibit an in-plane retardation of 190 to 390 nm, and exhibit a retardation of 0.28 to 0.67 in its thickness direction. The resulting vertical alignment liquid display device has a high contrast even when viewed from an oblique direction.

The liquid crystal display device of the present invention includes a first substrate, a second substrate, and a vertical alignment type liquid crystal layer provided between the first substrate and the second substrate, and includes a plurality of picture element regions each defined by a first electrode provided on one side of the first substrate that is closer to the liquid crystal layer and a second electrode provided on the second substrate so as to oppose the first electrode via the liquid crystal layer. The first substrate includes a first orientation-regulating structure in each of the plurality of picture element regions, the first orientation-regulating structure exerting an orientation-regulating force so as to form a plurality of liquid crystal domains in the liquid crystal layer, each of the liquid crystal domains taking a radially-inclined orientation in the presence of an applied voltage. The second substrate includes a second orientation-regulating structure in a region corresponding to at least one of the plurality of liquid crystal domains, the second orientation-regulating structure exerting an orientation-regulating force for orienting liquid crystal molecules in at least one liquid crystal domain into a radially-inclined orientation at least in the presence of an applied voltage.

A method of registering and vertically aligning multiply-layered images into a mosaic is described. The method comprises performing an iterative process of vertical alignment of layers into a mosaic using a series of defined alignment correspondence pairs and global registration of images in a layer using a series of defined registration correspondence points and then redefining the identified alignment correspondence pairs and/or registration correspondence points until a satisfactory result is obtained. Optionally, an initial global registration of each layer could be performed initially before commencing the alignment process. The quality of the result could be determined using a least squares error minimization or other technique.

A liquid crystal display (LCD) panel and driving circuit having a high response speed is provided. The LC panel at least includes a first group of gate lines, a second group of gate lines, and a first group of source lines, in which gate pulse signals can be fed to the LCD panel through the two groups of gate lines. Preferably, the LC panel further includes a second group of source lines, in which one of the two groups of source lines can be fed with the image data, and the other one is fed with a black image data. Accordingly, the LCD panel can only use the twisted nematic LC or the vertical alignment LC (VA-LC), without need of optically compensated birefringent LC (OCB-LC). Thus, the problems of a fast response speed LC panel using an OCB-LC can be avoided.
