  • Patent number: 7809296
    Abstract: A method and computer program for preventing excess supply of toner in an imaging device include detecting a change in a tribo-electric charge of toner after a period of inactivity of the imaging device, compensating a toner dispense control value, such as a PID (Proportional, Integral, Differential) value, based on the detected change in the tribo-electric charge of toner, and outputting the compensated toner dispense control value. A system for preventing excess supply of toner includes a sensor that detects a change in a tribo-electric charge of toner after a period of inactivity of the imaging device, and a controller that compensates the toner dispense control value based on the detected change in the tribo-electric charge of toner and outputs the compensated toner dispense control value. The detected change may be based on a charge prior to the inactivity.

  • Patent number: 7809551
    Abstract: A system for retrieving documents related to a concept from a text corpus includes a set of stored semantic classes which are combinable to express the concept each class including a set of keywords, each set of keywords including at least one keyword. Syntactic rules are applied to identified text portions which include one or more of the keywords. A rule is satisfied when keywords from the first and second semantic classes are in any one of a plurality of syntactic relationships. A concept matching module identifies text portions within the text corpus which include one or more of the keywords, for applying the syntactic rules to the text portions, and for identifying those text portions which satisfy at least one of the rules. Documents to be retrieved may include at least one of the identified text portions.

  • Publication number: 20100248118
    Abstract: The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a UV additive that renders them visible when exposed to UV light of a specific wavelength. By selecting the appropriate UV additive and ionic crosslinker, with optional chelating agent, the gloss of the toner may be tailored to match the gloss of any substrate, such as paper, to which the toner is to be applied, thereby further enhancing its invisibility under visible light.
