Abstract: Hardware cabinets contain air-cooled electronic components and are configured to operate in a data center or the like in which the cabinets are arranged in one or more rows and receive coolant air supplied to a cold-air aisle facing the cabinets. Heated air exiting the cabinets is directed to a hot-air aisle for HVAC system return in the data center. An air-flow device component of a hardware cabinet is positioned to create a curtain or wall of air extending from the housing to separate cold air in the cold-air aisle from hot air in the hot-air aisle. Hardware cabinets and retrofit kits using cross flow blowers are disclosed.

Abstract: An air-cooled electronic component cabinet has an air sampling conduit to enable smoke detection from air from different areas within the cabinet. An air sampling conduit has one or more orifices to sample air from the different areas within the cabinet, such as adjacent different electronic chassis assemblies or enclosures stacked in a rack within the cabinet. An axial fan or blower draws air samples into the conduit, or the air samples are drawn in by operation of convection or other airflow established within the cabinet. In the air sampling conduit, the air samples are mixed and conveyed for sampling by one or more smoke detection devices mounted, e.g., within the conduit, or within an attached expansion joint section to reduce the airflow velocity or accommodate multiple smoke detection devices. Orifices in the air sampling conduit varying in size or number at different conduit areas regulate associated sampled air proportions. A variety of configurations in which such air sampling conduits are deployed are presented.

Abstract: A first method for fabricating low-noise optical components for use in optical metrology systems includes shaping a glass substrate to obtain a desire shape and then coating the glass substrate with a reflective coating. A second method includes shaping a glass master die to a desired shape and then using the glass master to form a glass substrate to the desire shape. A third method includes diamond turning a substrate to a desired shape and then polishing the substrate to meet two surface conditions which in turn ensures that the scattered light is minimized and the metrology instruments performance is greatly increased. These conditions relate to a measurement of encircled energy compared to an ideal diffraction limited component of the same focal length and diameter.

Abstract: A combiner for optical beams includes a substrate overlaid by a multi-layer dielectric film stack. The substrate is a clear material and the dielectric film stack is a series of alternating layer of high and low refractive index. This gives the combiner relatively high reflectivity across UV wavelengths and relatively high transmissivity in the visible and longer wavelengths and allows visible light to pass through the combiner while UV light is reflected. At the same time dielectric film stack has minimal absorption and scatter. This means that the intensity of visible light maintains at least 90% of its intensity as it passes through combiner and UV light retains at least 90% of its intensity as it is reflected by combiner.

Abstract: The present invention provides for a method of and apparatus for compressing and uncompressing image data. According to one embodiment of the present invention, the method of compressing a color cell comprises the steps of: defining at least four luminance levels of the color cell; generating a bitmask for the color cell, the bitmask having a plurality of entries each corresponding to a respective one of the pixels, each of the entries for storing data identifying one of the luminance levels associated with a corresponding one of the pixels; calculating a first average color of pixels associated with a first one of the luminance levels; calculating a second average color of pixels associated with a second one of the luminance levels; and storing the bitmask in association with the first average color and the second average color. In one embodiment, the color cell includes a matrix of 4×4 pixels, the bitmask includes 32-bits and each of the color values includes 16-bits such that a compression rate of 4-bits per pixel is achieved. The present invention is particularly applicable to compress texture data such that the texture data can be more efficiently cached and moved during texture mapping. In that embodiment, the present invention can also support the compression of luminance, intensity and alpha textures.

Abstract: An optical filter for the selective attenuation of specific wavelengths of light includes at least one spectrally dispersive element, such as a diffraction grating or prism, in combination with an optical filter. A dispersive element separates broadband light into a constituent wavelength spread in angle space. An optical filter, or filter array, can block and/or attenuate specific wavelengths or wavelength ranges of interest while the light is angularly dispersed. A second dispersive element can recombine this filtered, separated wavelength fan of light into a coaxial broadband beam having a smoother intensity profile than the unfiltered beam.

Abstract: An infrared filter for an optical metrology tool includes a substrate having film stacks on opposing surfaces thereof. A first film stack can be used to reflect ultra-violet radiation and transmit radiation at non-ultraviolet wavelengths. The second film stack can be used to reflect visible to near-infrared radiation and transmit infrared radiation. The combination of film stacks can therefore extract infrared radiation from a broadband beam, with the remaining ultra-violet radiation and visible to near-infrared radiation forming the product of the filter. The filter can be used as part of the illumination or collection side optics in a broadband optical metrology tool.
