The invention relates to an automatic documentation tool and associated method. The method includes embedding comments into a plurality of source files defining the design, creating a configuration file including parameters associated with each source file, and extracting the comments from each source file responsive to the parameters. The method is capable of operating on a plurality of source files originating from a plurality of design tools. The method is capable of sorting through keywords preceding each comment and ordering the comments according to a user's request. The method is capable of receiving register definitions from a header file.

Extracting comment keywords from distinct design files to produce documentation

A pulse width position modulator (PWPM) includes a digital delay circuit that outputs multiple subclocks according to a native pixel clock. The multiple subclocks are each skewed within different time periods of the native pixel clock period. A skew pulse generator receives the multiple subclocks from the digital delay circuit and outputs multiple subpixels according to different logical combinations of the multiple subclocks thereby providing increased subpixel output resolution using the native pixel clock. A clock skew synchronizer aligns the subpixels with a line synchronization signal. The clock skew synchronizer allows lines in a printed image to be aligned with the line synchronization signal within subpixel resolution without using high frequency sampling circuity.

The invention relates to an inkjet temperature regulation controller that includes a time base circuit adapted to generate a clock signal and a head temperature sampler adapted to generate head temperature data by sensing print head temperature responsive to the clock signal. A preheat data generating circuit is adapted to translate the head temperature data into head preheat temperature data. A preheat data delivering circuit is adapted to provide the preheat temperature data to at least one preheating element. A monitor circuit is adapted to generate statistical data according to the head temperature data. The preheat data generating circuit receives updated head preheat temperature data responsive to the statistical data.
