    摘要： An optical and mechanical design of a sealed, non-round fluid-filled lens capable of providing variation of optical power. The fluid lens includes at least three optical components: at least one mostly rigid optical disc, at least one mostly flexible optical membrane and a layer of a transparent fluid that is in communication via a fluid channel with a reservoir of excess fluid contained in a reservoir that can be accessed to augment the fluid volume inside the fluid lens to change the power of the fluid lens. The fluid lens is capable of providing correction of spherical and astigmatic errors, and utilizes contoured membranes to minimize image aberrations.

    摘要： A gas release port and methods of fabricating such port are described herein. In an example embodiment, the gas release port is for an oil-free compressor. The compressor includes a compressor housing with a compression chamber having at least one rotor bore therein. The housing also has an inlet nozzle with the discharge port. The nozzle is configured to permit process gas to bleed out before a complete release of compressed gas. The compressor also includes at least one rotor assembly positioned within the frame. The rotor assembly includes a rotor shaft and a rotor. The rotor is positioned within the rotor bore.

    摘要： To reduce the performance penalty associated with frame buffer memory access times for each page when rendering a primitive having scan lines which cross page boundaries, rendering is constrained to a single page at a time. All pixels mapping to a currently-cached frame buffer page are rendered before loading a different frame buffer page into the cache in order to render other pixels within the primitive. Any pixels within a scan region which map to a different page than the active page are temporarily skipped until all pixels mapping to the current page are completed. Only when no more pixels require rendering within the primitive which map to the currently active frame buffer page is another frame buffer page loaded and all pixels mapping to that page are rendered. In processing a scan region which crosses a page boundary, the next pixel or pixel group to be rendered is examined to determine if it maps to the currently active frame buffer page. If so, it is rendered; if not, however, the position is latched, together with any other necessary state information, and rendering proceeds with the next scan region. Once all pixels for a currently active page are rendered, the latched position is loaded, together with the frame buffer page necessary to render the corresponding pixels, and rendering of the primitive proceeds until complete.

    摘要： A method and apparatus for generation of pixel lookahead information in a cached computer graphics system is provided. For each pixel-based memory operation, several data items may be generated, such as numerical values representing a coordinate point in an image coordinate space or display coordinate space and characteristic data representing a color value or depth value for the pixel. In addition, lookahead data correlated with the coordinate data is generated. The pixel operation is then issued with the characteristic data, the coordinate data, and the lookahead data. The lookahead data may contain a lookahead vector, which specifies a lookahead vector direction and a lookahead vector length, and a lookahead valid flag, which indicates whether associated lookahead data is valid for the pixel operation. The lookahead direction may be computed based on the coordinate data of the pixel operation and coordinate data for a pixel operation to be performed within a threshold number of pixels operations from the pixel operation. By providing lookahead information based on the rendering state of the graphics subsystem, pixel operation intentions may be indicated prior to the issuance of a pixel operation so that the pixel data may be prefetched into a cache.

    摘要： A method and system for an approximation of a filter function for computing a characteristic value of an output pixel based on characteristic values of a plurality of input pixels is provided. A filter response curve adjustment value is obtained, preferably from a lookup table, based on a distance interval between coordinates of the output pixel and coordinates of a selected input pixel. A normalized filter response curve input value is computed based on the distance interval and the filter response curve adjustment value, preferably by adding the values together. The characteristic values at a plurality of input pixels are obtained. A linearly interpolated value for the characteristic value of the output pixel is then computed based on the characteristic values of the plurality of input pixels and the normalized filter response curve input value.
