  • Patent number: 11900588
    Abstract: An image based correction system compensates for the image quality artifacts induced by thermal ghosting on evolving imaging member surfaces. With thermal ghosting directly tied to previous image content, a feed forward system determines thermal ghosting artifacts based on images previously rendered and generates an open loop gray-level correction to a current image that mitigates undesirable ghosting. For example, the correction system compensates for the thermal ghosting by making the current image “lighter” in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions. A temperature sensor is used to measure the temperature of the imaging blanket due to the stresses induced by the image. This data is used to learn the parameters of the temperature model periodically during operation, and used in subsequent corrections to mitigate thermal ghosting in spite of changes in blanket properties over use and time.

  • Patent number: 11898957
    Abstract: Apparatus and methods are provided for quantitative detection of mercury vapor in gas samples using a film of nanoparticles. The localized surface plasmon resonance (LSPR) of an amalgam nanoparticle is sensitive to adsorbed mercury mass. The equilibrium mass of mercury on a gold nanoparticle is a function of the surrounding vapor concentration and the temperature of the gold. A device that introduces a temperature-controlled gold nanoparticle film to a controlled flow of sample gas responds predictably to a given mercury vapor concentration when optically probed in situ. Controlling the temperature of the film allows for control of adsorption and desorption rates. Equilibrium plasmonic mercury detection, described herein, removes the cycling necessary for many gold-based mercury analyses. Methods are given for the operation and analysis of the temperature-stabilized gold nanoparticle mercury sensor.
