Abstract: An improved luminaire configured to detect dawn and dusk and to turn on, dim and/or turn off in response to the ambient light level. The luminaire is configured to delay turning on, dimming, and/or turning off such that light emitted by the luminaire can be utilized by neighboring luminaires in calculating the ambient light level in determining if dawn, dusk, or other low light condition has begun or is ending. The luminaires further utilize a timer for measuring the ambient light so as to avoid momentary or brief ambient light changes caused by, for example, weather conditions or temporarily reflected light such as by a vehicle positioned proximate to on or more of the luminaires.

Abstract: The software on the host machine examines a pixel, either alone or in relation to adjacent pixels. Based on the image data contained in the pixel or group of pixels, a multi-bit value is generated that can be used by the printing device to easily reproduce the necessary detail of the original pixel. The multi-bit value also contains print engine control parameters to handle items such as toner miser mode, toner explosion, edge roll off, etc. The multi-bit value can be generated algorithmically by using a lookup table or by some combination of these methods.

Abstract: A method for image processing loads a cache line width column of image data into a data cache. The cache line width column of image data is then processed to enhance the image data; and the enhanced image data is then outputted.

Abstract: A method for use in faxing with a multifunction printer. A control sheet indicative of a set of files accessible by the printer is printed. The control sheet is optically scanned so as to recognize marks made by a user which are indicative of at least one designated file. The designated files are rendering into fax-formatted output data, and at least some of the output data is faxed to each of at least one designated destination.

Abstract: The printing speed of a page printer is modified relative to rasterization execution time (RET) for display commands that define images to be printed on each page strip of a page. The printer includes a variable frequency clock for producing a plurality of clock frequencies for modifying the printing speed. A processor compares the RET for each page strip with a threshold value. When a complex page strip is found whose RET exceeds the threshold, the variable frequency clock is appropriately controlled to generate a lower frequency clock signal to the print engine. The lower frequency signal causes the print engine to operate at a modified (slower) rate for a sufficient amount of time on any previously queued page strip(s) to provide an extended time frame for allowing the complex page strip to be rasterized. Printing speed is slowed, but rasterization time (clock speed) for the complex page strip is not slowed.
