    摘要： An apparatus compensates for mechanical disturbances during a print process by adjusting the generation of image generating head actuation signals in anticipation of a mechanical disturbance. The apparatus includes a printer controller for generating signals to coordinate movement of components with a rotating image receiver in a printer and for generating data identifying a process disturbance arising from interaction of the rotating image receiver with the components and an expected time for the process disturbance, a process disturbance compensator for generating a process disturbance compensation signal that corresponds to the process disturbance identification and timing data, and an image generating head controller for adjusting an image generating head actuation signal with the process disturbance compensation signal.

A vehicle image can be captured by the image capturing unit in order to estimate speed of the vehicle utilizing an ALPR unit. The license plate characters can be located and extracted from the captured image. A distance of the license plate from the image capturing unit can be calculated utilizing a physical character height from a reference point of the image capturing unit and a pixel character height generated by the ALPR unit. A position of the license plate in the field of view of the image capturing unit along with the distance information can be utilized to determine a height of the license plate from a road surface. The height of the license plate can be employed to accurately estimate the vehicle speed.

    摘要： A power saving apparatus and method for imaging modules in a variable data lithography system is provided. The imaging modules are arranged adjacent to each other to project a scan line of imaging data on a rotating imaging member in a variable data lithography system. The imaging module includes a look ahead buffer which stores imaging data and from which the stored data is read out for projection on the imaging member. The power saving apparatus uses an image look ahead concept to save part of the power consumed in the imaging modules in the projection mode of operation by selectively powering each laser source based on the imaging data in the look ahead buffer.
