  • Patent number: 6639669
    Abstract: In a color analysis method in which sheets with multiple different color printed test patches are moved relative to a color analyzing spectrophotometer, and in which fiducial marks are printed adjacent to respective test patches and optically detected by a fiducial mark detector to provide a triggering system for the respective test patch analysis, there is provided automatic diagnostic testing of the spectrophotometer and the fiducial mark triggering system, including automatically generating special test sheets, some of which may include test areas of varying density black.
    Type: Grant
    Filed: September 10, 2001
    Date of Patent: October 28, 2003

  • Patent number: 6603551
    Abstract: A method is provided for measuring the color of irregular surface materials, including textiles which may provide dissimilar color measurements from different viewing angles, by illuminating a sampling area of the irregular surface material approximately perpendicularly thereto and measuring the color reflected from that area at a substantial angle, preferably about 45 degrees, with a plurality of separate photodetectors arrayed circularly around the illuminated sampling area of irregular surface material to receive the reflected illumination from substantially opposing directions and at a substantial angle to the illuminated area, for providing a more accurate yet lower cost color measurement system for textiles that can be used easily, quickly, and uncritically in terms of the handling, positioning and orientation of the textile material being tested.

  • Patent number: 6205416
    Abstract: A computer network environment (10) allowing connection of a client system (36) to a legacy host system (18,19) using a server (26) is provided The computer network environment (10) includes a legacy host system (18,19) having TCP/IP connectivity. The legacy host system (18,19) is operable to support a terminal session for access to the legacy host system (18,19). The computer network environment (10) also includes a server (26) operable to communicate with the legacy host system (18,19) across a persistent TCP/IP socket connection (30). The computer network environment (10) further includes a client system (36) executing an applet process (42) under a web browser (38).

  • Patent number: 5907155
    Abstract: An apparatus for maintaining a substantially consistent current to voltage relationship in a corona charging device having an electrode energized by an AC voltage biased by a first DC offset voltage which is modified by a second DC voltage, and a control surface energized by a third DC voltage which is also varied by the second DC voltage. The apparatus includes a system for monitoring a portion of the AC voltage, and for superimposing the first DC voltage on the monitored voltage to generate a control voltage having an AC component and a DC component, and for further superimposing the second DC voltage on the control voltage to vary the control voltage in response to changes in the second DC voltage. The control voltage is then applied to the electrode of the corona charging device. The apparatus provides a constant DC offset coronode voltage tracking circuit that maintains a substantially consistent current to voltage relationship in a scorotron-type corona charging device.
