  • Patent number: 8147026
    Abstract: A method and system for improved image quality using an image quality matching method is used to match the optical density of single prints produced on multiple print engines by first sensing the optical density of a first image produced on a first print engine and then sensing the optical density of a second image produced on a second print engine before comparing the optical densities and determining if they are substantially equal. If they are not equal set points and exposures are adjusted on one or both print engines until the differences between the optical densities is less than 0.05, preferably 0.03. The density is changed by adjusting the initial voltage on the primary imaging member of at least one print engine and/or by adjusting the exposure of the primary imaging member of at least one print engine.

  • Patent number: 7911614
    Abstract: The non-contact measurement probe is capable of dimensional measurement of a workpiece while it is being machined, and reporting dynamic error for real-time compensation by the machining tool. Measurement includes diameter and roundness of the workpiece. The measurements are automatically fed back to a machine controller for intelligent error compensation. Based on known laser Doppler techniques and real time data acquisition, the probe delivers dimensional accuracy at few microns over a range of 100 mm. The measurement probe employs a differential laser-Doppler arrangement, allowing acquisition of information from the workpiece surface. Moreover, the measurements are traceable to standards of frequency allowing higher precision.
