20150201117 | DEVICE AND METHOD FOR CHARACTERIZING A SAMPLE USING LOCALIZED MEASUREMENTS - Device for characterizing a sample includes a measuring instrument for determining a physical characteristic of the sample at one point thereof; a positioning system for positioning the measuring instrument relative to the sample, to obtain a measurement at a point localized on the sample. The positioning system includes: a locating target connected to the sample and defining a reference system linked thereto; elements for acquiring and analyzing images, including lighting elements for illuminating the target; an optical imaging system connected to the measuring instrument for acquiring an image of at least one portion of the target; and image analysis elements for analyzing the image to determine the position and orientation of the optical imaging system relative to the target; calibration elements for determining the position of the measuring instrument relative to the optical imaging system; and processing elements for processing the results of the image analysis and of the calibration. | 07-16-2015 |

20100189475 | Intermediate Transfer Belt Steering System - Disclosed are embodiments that use multiple, belt-steering systems to control and maintain alignment of an endless belt. The position of the edge of the belt is measured by multiple belt edge sensors and then corrected by at least two steering rollers connected to corresponding steering mechanisms. The steering mechanisms tilt the rollers in order to selectively adjust the lateral position of the belt. Steering can be controlled independently with the tilt of each steering roller being adjusted based solely on information obtain from a corresponding belt edge sensor. Alternatively, steering can be controlled dependently with the tilt of each steering roller being adjusted based on information obtain from multiple sensors at multiple locations and further based on the predictable impact of the simultaneous movement of both rollers on belt positioning. In addition, at least one of the steering rollers can also be configured as a drive roller. | 07-29-2010 |

20100245467 | Print Head Maintenance System For An Ink-Jet Printer Using Phase-Change Ink Printing On A Continuous Web - A maintenance assembly for cleaning a plurality of printheads in a printing machine comprises two or more cleaning members, each of the cleaning members sized and positioned to clean at least one but less than all of the plurality of printheads when in a cleaning position. A drive mechanism associated with each of the two or more cleaning members is configured to selectively move an associated cleaning member to and from the cleaning position and a retracted position. The cleaning members are supported on a frame with a mechanism provided for translating the frame into position juxtaposed with the plurality of printheads and a further mechanism to swipe the cleaning members across the printheads. The maintenance assembly is operable to clean only selected printheads in a single operation. | 09-30-2010 |
