摘要： An improved, large-format digital inkjet print engine that includes a group of co-operating print engine subassemblies that embody various novel elements that both discreetly and cumulatively advance the current art. The group of subassemblies and sensors cooperate to produce high quality graphic images using a plurality of different colors of ink and different types of print media at speeds several times faster than similar conventional inkjet printers. In addition, the use of cooperating elements permit the manufacture of complex, large-format digital color inkjet print engines that are less expensive to fabricated, operated, and serviced. The present invention finds use in large-format digital color printing and imaging, where successful repeatable printing requires precise placement of droplets of ink, toner or other marking material on a print medium such as paper, vinyl, film, or similar substrate.

摘要： Apparatus for determining the number of cycles occurring in a frequency modulated signal during a sample period, including not only the number of full cycles but any portion of a cycle, by determining the number of whole cycles and adding to this a value obtained by counting the number of high frequency clock cycles occurring between the time of the last rising edge of a full cycle and the end of the sample period, and the number of high frequency clock cycles occurring from the last rising edge prior to the start of the sample period and the start of the sample period and the number of high frequency clock cycles in a whole cycle.

摘要： A low voltage comparator circuit is utilized for comparing the current flowing into and out of one of the electrodes of a gas discharge device with a preselected value. The comparator provides an output signal to an optical isolation means for generating light waves in response to the comparator means output. The optical isolation means includes a photosensitive means for providing an output signal which is responsive to the intensity of light waves generated by the light generating means. The output of the photosensitive means is electrically connected to an input means for a current control which includes a first terminating means electrically connected to the one electrode of the gas discharge device, and a second terminating means electrically connected to the high voltage supply.
