  • Automated camera flat fielding and alignment
    Patent number: 8923571
    Abstract: In an example, a method for automated camera flat fielding and alignment may include determining a magnification of a camera relative to a first camera axis that is generally parallel to a first print media axis by evaluating first and second magnifications between transitions from a first color to a second color on a setup plot. The method may further include determining, by a processor, a rotation of the camera relative to the first camera axis such that the first magnification is approximately equal to the second magnification.

  • Measuring latency in a video conference system
    Patent number: 8330792
    Abstract: A method of measuring video latency between a sender and a receiver in a video conference system is disclosed. In an embodiment, the method includes initiating an electrical signal from a first location in a video conference system, transmitting the electrical signal through the video components of the video conference system, reflecting the electrical signal back through the video components of the video conference system and measuring the latency of the electrical signal at the first location related to the transmission and reflection of the electrical signal.

  • Laser marking
    Patent number: 7005603
    Abstract: A method for marking a polymeric surface includes directing a first laser beam on the surface to form a lightened area on the surface and directing a second laser beam upon the lightened area to form a mark darker than the lightened area.
