  • Publication number: 20110178975
    Abstract: In a scheduling or planning process, a hybrid process is determined representing operation of a system. The hybrid process includes stochastic jumps. An approximate linear program is constructed respective to the hybrid process and a set of control actions for controlling the system. The approximate linear program includes a stochastic jump constraint term representative of stochastic jumps of the hybrid process. The approximate linear program is solved. The system is controlled based on the solved approximate linear program.

  • Publication number: 20110177441
    Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a cyan toner with a lower colorant loading in addition to a first cyan toner. In embodiments, the cyan pigmented particles may be cyan emulsion aggregation toners. In accordance with the present disclosure, a pair of cyan toners are matched in color, wherein the color of a first cyan toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second cyan toner, which is lighter than the first cyan toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light cyan toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 500 and 600 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers.

  • Publication number: 20110175280
    Abstract: Registering a sheet in a differential drive registration system by identifying observed state values corresponding to a sheet handled by the differential drive registration system. The method also including determining an error vector, wherein the error vector is defined by a difference between the observed state values and reference state values for the sheet. Control input values are also determined based on the error vector, a set of control parameters, and the observed state values. The control input values being determined such that there is a linear differential relationship between the observed state values and the control input values. Additionally the method includes generating drive wheel velocities in the differential drive registration system based on the control input values. The identifying and determining steps being repeated for the sheet in a closed-loop process such that the observed state values substantially track the reference state values.

  • Publication number: 20110176735
    Abstract: A form identification apparatus includes a form registration unit and a candidate registered form extracting unit. The form registration unit registers stylized forms as registered forms, and sets, for each of the registered forms, content of form processing and a threshold for determining a degree of difference in accordance with the content of the form processing. The candidate registered form extracting unit extracts, as a candidate registered form, the registered forms in which content of form processing executable on a to-be-processed form has been set, based on a degree of difference between an image of the to-be-processed form and an image of each of the registered forms and the threshold.
