  • Patent number: 7035945
    Abstract: One embodiment of the present invention provides a system that facilitates identifying expansion cards installed in a computer system. The system operates by first examining a device tree for the computer system to identify nodes within the device tree that are associated with the computer expansion cards. Next, the system obtains a subset of parameters from the device tree that are associated with the computer expansion cards, and then performs a pattern match between the subset of parameters for each card and entries in an information file to identify each computer expansion card.

  • Patent number: 7015488
    Abstract: In an exposure apparatus of the invention, for a spatial light modulator, each of a plurality of pixel portions fewer than the total number of the pixel portions is controlled with a control signal generated according to exposure information. Namely, a part of the pixel portions is controlled without controlling a whole of the pixel portions on the substrate. Thus, the number of pixels in the pixel portions is decreased, and transfer time of the control signal becomes short. This enables modulation speed of the laser beam to be increased and the high-speed exposure to be performed. An incorporated laser light source, in which the laser beams are incorporated and struck on the optical fiber, is preferable to the laser device. By adopting the incorporated laser light source, high brightness and high output can be obtained, and it is preferable to the exposure of the spatial light modulator. Since the fiber array is obtained with few optical fibers, it is low cost.

    Abstract: A method of bleaching fabrics comprises contacting the fabrics with a liquor containing a surfactant and a chlorite such as sodium chlorite and irradiating the fabric and/or the liquor with ultra-violet light derived from an artificial source or from daylight. The liquor has a pH ideally above 8.5. A UV-light exposure equivalent to 2 hours daylight gives good results. The liquor may contain a number of other components common in bleaching products. The composition is a particulate detergent composition comprising at least 1% by weight of surfactant, 0.1-40% by weight of chlorite and less than 20% by weight of water, yielding a pH of about 8.5-11 when dispersed in water at a concentration of 0.5-10 g/l. The compositions are stable on storage and the time and degree of bleaching can be controlled by control of the exposure to UV-light.

  • Patent number: 4456452
    Abstract: A process is proposed for bleaching textiles or removing stains from textiles and for combating micro-organisms in or on organic or inorganic substrates, or for protecting the latter against attack by micro-organisms, by treating the textiles or the substrates to be freed of or protected from micro-organisms with a water-soluble zinc phthalocyanine or aluminium phthalocyanine, in the presence of water and under irradiation with light, in which process a sulfonated zinc phthalocyanine or aluminium phthalocyanine which is further substituted by neutral groups which do not confer solubility in water, for example by halogen atoms or pseudo-halogens, or a mixture of these phthalocyanine compounds, is used as the water-soluble zinc phthalocyanine or aluminium phthalocyanine.

  • Patent number: 4445901
    Abstract: A fabric conditioning composition in solid or liquid form contains a fabric softening agent and a halite material such as sodium chlorite as a bleaching and/or germicidal agent. When in liquid form the composition may contain a stabilizing material to improve physical stability. In use, fabrics are contacted with a liquor containing the composition and the fabric and/or the liquor is irradiated with UV-light from an artificial source or from daylight.
