A flashing apparatus for external use on structures is described. The flashing apparatus essentially serves as an accessory for fiber cement siding and is designed to provide a certain level of water resistance in the seams between the ends of the sections of the siding. The flashing apparatus has a forward projecting flange and comes in various heights to accommodate different sizes of fiber cement siding that may be used in constructing a structure.

A system and method for generating achromatic components for output incorporate receiving input color data defined in a first color space. The received input color data is converted to intermediate color data defined in an intermediate color space. Typically the intermediate color space is defined only in terms of chromatic components. A black or achromatic component is then calculated. The black or achromatic color component is a function of both the input color data in the first color space and the intermediate color data in the intermediate color space. This black or achromatic color component is associated with the intermediate color data for further processing and output.

An automobile vent extender that decreases discomfort by allowing hot and cold air to be directed from an automobile vent directly onto a body portion of an automobile passenger. Preferably, the automobile vent extender removably attaches to a vent diffuser embedded within the dash of an automobile.

Techniques for black and white pattern rendering that increase processing speed and reduce memory requirements while providing improved pattern selection performance are provided. The hue angle and lightness of a color input are determined. The hue angle is used to index into a lookup table of halftone functions that specify default frequency and spot functions for a hue angle range. For each selected halftone, the determined hue angle is substituted from the hue angle range if the determined hue angle differs from the last determined hue angle range by more than a threshold difference value. The determined lightness is used to determine the halftoning threshold value and rendering then occurs.

Image values are adjusted based on image object or component type and in a perceptually linear manner based on user set control values. Image values are also scaled based on dynamic ranges of an input and output device, such as a monitor and a printer. A lookup table is generated for converting image values from an adjustment color space to a printer color space by measuring a test print, inverting the measured data to an adjustment color space and generating a final lookup table based on the adjustment color space data and the inversion color space data. Image values are adjusted in a perceptually linear manner by converting the image values to a perceptually uniform color space and adjusting the values in the adjustment color space before converting the values to a printer device space.

An apparatus for filtering and cooling liquid, with four filtration chambers are connected by a series of passageways. The apparatus is mounted on a cart so that it may be rolled into position under a machine quickly and easily. Once the apparatus is in position, the machine is drained of its debris-laden oil which flows directly into the first chamber and through the first wire mesh filter. The liquid is then forced either by gravity or by pressure through the remaining chambers and their respective filters which have progressively smaller pore sizes. The tortuous movement of the liquid around the weirs helps to cool the liquid while the filters remove foreign particles from the liquid. Once the liquid reaches the fourth chamber, a pump is used to pump the cleansed liquid back into the machine so that it may be reused. The inlet to the pump may be fitted with an optional fifth filter element. Each chamber houses a tray assembly which includes a handle that protrudes above the chamber, a bracket that hold the replaceable wire mesh filters, and a catch pan that collects any solids that have settled to the bottom of each chamber. The filters have gaskets to prevent fluids from by-passing the filters and the filter pore size can vary with the application. The first embodiment may be operated at atmospheric pressure, while a second embodiment is equipped with a top on the tank which allows the system to be pressurized.

A method and apparatus for blending pictorial and graphical look-up tables is provided. The blended look-up table, addressable by image signals from both pictorial and graphical objects, produces printer signals which are a blend of the output of the pictorial and graphical look-up tables. For image signals that are inside the pictorial gamut of the printer, only the output of the pictorial look-up table is used in the blended look-up table. For image signals that are outside the pictorial gamut, a blend of the output of both pictorial and graphical look-up tables is used in the blended look-up table. To blend the tables, graphical and pictorial image signals are selected from the surface of the graphical and pictorial gamut which have the same hue and luminance as the desired image signal. Printer signals output by both the graphical and pictorial look-up tables are weighted in accordance with the proportions of graphical and pictorial character container in the desired image signal, determined from the difference in saturation between the desired image signal and the selected graphical and pictorial image signals. The weighted printer signals are added and mapped to the desired image signal, the mapping being stored in an image signal translator.
