摘要： A technique of approximating exponential transformations such as gamma correction is disclosed that achieves high resolution without requiring relatively large RAMs for lookup tables or specialized DSP processors. The technique includes the acts of scaling the pixel values according to their values, wherein smaller pixel values are scaled with larger scale factors and larger pixel values are scaled with smaller scale factors; quantizing the scaled pixel values; looking up the quantized pixel values in a lookup table to provide lookup values; and scaling the lookup values responsive to their scale factors to provide the gamma-corrected pixel values.

摘要： This invention relates to a method for the removal of oil from an oil in water emulsion by passing the emulsion through a fibrous structure comprising fibres having finely divided particles having an average size of one micron or less and which exhibit oleophilic and hydrophobic properties adhered to and penetrating their outer surfaces, and removing the coalesced oil droplets so formed.

摘要： The present invention is directed to a serial bus extension that provides for a new class of 1394 devices called versaphy devices. A versaphy device has a static (permanent or semi-permanent) address or versaphy label. In addition, the versaphy device has a new register structure called a versaphy register. The versaphy register may contain the versaphy label. The versaphy register can be written to by non-local devices such a controller. New simple versaphy packets are defined to facilitate communication between a versaphy device and a controller. The versaphy device can transmit unsolicited responses. These features reduce the complexity necessary for a device to connect to a 1394 bus and, therefore, reduce the cost of these devices.
