  • Apparatus and methods for feeding sheets of media to a media processor
    Patent number: 6923437
    Abstract: Apparatus for feeding sheets of media to a media processor may include a take-away roller for engaging a first sheet of media. It may further include a first sensor for detecting a movement of the first sheet of media past the take-away roller. The apparatus may include a feed roller and a second sensor for detecting a movement of the first sheet of media past the feed roller. The apparatus may further include a second motor for driving the feed roller. Also, the apparatus may include an ejection roller, a third sensor for detecting the movement of the first sheet of media past the ejection roller, and a third motor for driving the ejection roller.
    Type: Grant

  • Apparatus and methods for averaging image signals in a media processor
    Publication number: 20040101208
    Abstract: A first signal and a second signal are obtained using a first and second image sensors, respectively. The first signal and the second signal are converted from analog to digital form. The first signal and the second signal are then averaged to improve the signal to noise ratio of the resulting signal. The first signal may be obtained using a channel corresponding to a first channel. The second signal may be obtained using a channel corresponding to a second channel. Further, a third signal may also be obtained using a channel corresponding to a third channel. Then, the first, second, and third signals may be averaged to generate an averaged signal.
