An original mesh is provided with a bounding surface and a convex hull surface. A first tessellation links the convex hull to the original mesh, and a second tessellation links the bounding surface to the convex hull. Using the tessellations to find a first intersection between a ray and the original mesh by finding a first intersected polygon of the bounding surface, and then traversing adjacent intersected polygons starting from the first intersection until the intersection is found. When the ray is moved, a second ray-surface intersection can be found by finding a polygon locally near the first intersection and containing a first intersection with the moved ray, traversing out from the local polygon through adjacent polygons intersected by the moved ray, and determining whether traversed polygons are unoccluded based on whether they are part of the convex hull surface.

The present invention relates generally to assembly techniques. According to the present invention, the alignment and probing techniques to improve the accuracy of component placement in assembly are described. More particularly, the invention includes methods and structures to detect and improve the component placement accuracy on a target platform by incorporating alignment marks on component and reference marks on target platform under various probing techniques. A set of sensors grouped in any array to form a multiple-sensor probe can detect the deviation of displaced components in assembly.

A hydraulic hammer having a sealing bushing includes a percussion piston that delivers strokes to a tool. A lower part of the percussion piston is sealed with respect to a frame by the sealing bushing, which includes one or more lower seals. The sealing bushing does not contribute to the bearing of the percussion piston and it is arranged in place through the lower end of the hydraulic hammer.

The present invention provides a method for patterning a quantum dot layer and a method for manufacturing a quantum dot color filter. The method for patterning a quantum dot layer according to the present invention uses a photoresist layer having a patterned structure as a shielding layer to subject a monocolor quantum dot layer to etching to form a patterned quantum dot layer. The method simplifies the constituent components for making a quantum dot paste that is used to form a quantum dot layer and simplifying a surface chemical environment of the quantum dots to thereby increasing light emission efficiency of the quantum dot. Further, the method may manufacture a fine quantum dot pattern, greatly improving the resolution of the patterned quantum dot layer. The method for manufacturing a quantum dot color filter according to the present invention is applied to manufacturing a quantum dot color filter on the basis of the above-described method for patterning a quantum dot layer and the quantum dot color filter so manufactured has a fine quantum dot pattern, the light emission efficiency of the quantum dots being high to thereby effectively improve the resolution and backlighting utilization of a display device.

A method of determining a corneal thickness and an apparatus for determining the same. The method comprises the following steps of illuminating a cornea by a plurality of stimulator point light sources, capturing an image of the cornea comprising reflected images of the stimulator point light sources, obtaining a first model representing an anterior surface of the cornea, constructing a second model representing a posterior surface of the cornea from the image by ray-tracing the reflected images of the stimulator point light sources towards the first model representing the anterior surface of the cornea, and determining the corneal thickness from the first model representing the anterior surface and the second model representing the posterior surface.

Systems and methods for approximating terrain data representing a water surface are disclosed. A computer-based geographical information system for approximating terrain data representing a water surface is provided. The system includes a mesh simplifier and a surface inversion corrector. The mesh simplifier simplifies initial water surface and water bottom meshes. The surface inversion corrector corrects simplified water surface and / or water bottom meshes to avoid having a water bottom surface incorrectly appear above a corresponding water surface in a display view. In one example, the mesh simplifier simplifies the initial water surface mesh while accounting for water / land boundaries. The mesh simplifier also simplifies the initial water bottom mesh while accounting for geographic features and / or water / land boundaries. A computer-implemented method for approximating terrain data representing a water surface is provided. In further embodiments, systems and methods for altering tile information received at a client device are provided.
